Re: [PHP-DB] Re: Beginners Problem
Andy,
Thanks for your comment. What I posted is only part of my code though,
as the entire thing is a bit long, and with all the includes rather hard
to follow unless I posted the whole file set. Above the piece I posted I
have code to do slashing, and some MD5 hashing, as well enforcing string
lengths. So the $password I use in the query is actually MD5 hashed
already. I know I need to improve the security though, as my current
code do not counter for every possible attack, so your input is much
appreciated.

Could I recommend a more secure approach:
1) using two hashes to protect the data (in case the database is
compromised they are both one-way hashes, and using two protects
against collision attacks whereby a different password string
generates the same hash as the original password)
2) escaping user input to protect against SQL injection attacks (nasty
queries can get more data from the database than your original query
intended, or change the query's intended functionality).
Instead of:
$chkuserquery = SELECT userID
FROM $TB_USERS
WHERE `loginID`='$loginID' AND `password`='$password'
LIMIT 1;
$chkuser = $db-query($chkuserquery);
This example utilises the mdb2 database layer:
$user_credentials = array( //these are the credentials the user supplied
'user_name' = addslashes($username), //escape username input
'user_password_md5' = md5($password), //generate hash, no
injection is posisble
'user_password_sha1' = sha1($password) //due to 'scrambling' of string
);
foreach ($user_credentials as $k = $v) {//build string
$query_values .= $k . '=' . $db-quote(trim($v)) . ' AND ';
}
$query_values = '(' . substr($query_values, 0, -5) . ')'; //format
string and remove AND
$sql = SELECT COUNT(user_id) AS user_count FROM user WHERE $query_values;
$result = $db-query($sql);
//this if not only returns a row from the database query, it then
checks if the user_count
//field contains more than one or more results. if so, login is correct
if (($row = $result-fetchRow(MDB2_FETCHMODE_ASSOC)) $row['user_count']){
$valid_login = true;
//session - database etc
}
for this example, using 'root' and 'password', $query_values is:
(user_name='root' AND
user_password_md5='5f4dcc3b5aa765d61d8327deb882cf99' AND
user_password_sha1='5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8')
This code is identical in functionality to the previous example,
except the query has no LIMIT - this is not required as it prevents
the possibility of coding error handling for multiple accounts
(perhaps unnecessary, excepting very secure applications).

You should probably check out http://php.net/mysql_query for more
information on this function. The difference between empty result
and invalid query is significant. Once you've determined that the
query is valid, you must also then check to see if it returned any
rows, possibly using a function like mysql_num_rows.
I usually skip the validity check and simply check for rows. But then I
also write my code a little differently, which may be why it doesn't break.
This is part of my login code:
$chkuserquery = SELECT userID
FROM $TB_USERS
WHERE `loginID`='$loginID' AND `password`='$password'
LIMIT 1;
$chkuser = $db-query($chkuserquery);
if($db-num_rows($chkuser)) {
$userID = $db-result($chkuser,0);
$ip = $_SERVER['REMOTE_ADDR'];
// update active session
$query = UPDATE $TB_SESSIONS
SET `userID`='$userID',`logintime`=NOW(),`loginIP`='$ip'
WHERE `sessionID`='$sessionID'
LIMIT 1;
$result = $db-query($query);
$alert_level = 1;
$alert_message = 'You are now logged in. Please remember to logout
when done.';
} else {
$alert_level = 3;
$alert_message = 'Username and/or password incorrect';
}
May deserve some elaboration, as this is just a piece of a much bigger code.
$TB_USERS and $TB_SESSIONS are merely variables (constants) set earlier
so that I can re-use the code more easily for different projects. $db is
a simple database object that's merely a wrapper for the mysql
functions. Inside $db, all the mysql functions have the or die() part
set with mysql_errno() and mysql_error() which catches invalid queries.
I built my own sessions system, using the database and cookies. There's
always a session active, that's why this part of the code doesn't check
for it. I made it this way so I can run the login/logout script at any
phase of the code, without having to worry about setting sessions and
cookies before it sends the headers.

In the users table I then simply have a boolean field called 'confirmed', that's set to 0 (false) by default. When a user's email address have been confirmed, this field is changed to 1 (true). The only reason I have expiration time in this table is for cleanup purposes. 3.) Email the mail to the address specified with the url to the confirm page one must send the email manually or is there any automatic generator for email sending to users.? Read up on the mail() function. It's actually pretty simple. All you have to do is send an email, with some proper explanatory text, with a link to your confirm.php script (or what you choose to call it), either with a direct link with a get statement including the confirmation code, or with a link to the confirmation script, and then the confirmation code and instructions on how to enter it. Or at best: offer both options. Then simply have your user registration/signup code send the email whenever a user registers. this will confirm that they did in fact check thier email. how exactly, can explain little bit.? Make the code generate a unique confirmation code (this is pretty simple), and then just have your confirmation script compare the confirmation code with the one in the database. If there's a match then the user to whom you sent that particular code is confirmed. All of the code needed to do this is actually fairly simple to write.

So far, I have found a few mistakes in your SQL:

Why do you have backtick-quotes around variant? Know that backticks are used
to call system commands. You also use these backticks in the ORDER BY lines.
My guess is the backticks are causing your problems.
Because they have to be there for MySQL to understand the query ? I
sometimes have field names where part of the name is the same as a command,
so without the ticks MySQL can't understand the queries. They're actually
in the documentation for MySQL, so I don't get why it would cause problems.
I always use them, and when I don't, I have problems. And the ORDER clause
DOESN'T WORK without them... ever, when I try to do without them and have
more than order clause.
$query .= AND make.makeID='.$_GET['make'].';
...
$query .= AND make.makeID0;
If make.makeID is a number field, why is the value in quotes for the cases
where $_GET['make'] is set? Same with socket.socketID a few lines down.
Because it doesn't matter, function-wise, if they're there or not for
numbers. And it's easier and faster to just put them in for everything,
than remembering to exclude them for numeric fields, and include them for
non-numeric. Yeah, it takes MySQL a little longer to have to convert from
text to number and such, but it's a microscopic amount of time.
Unrelated but very important, putting form variables (either GET or POST)
directly into a query is dangerous. If I create a copy of your form and fill
$_GET['search'] with eg: a%';DELETE * FROM model;SELECT * FROM model WHERE
something LIKE '%a
Your query will be like this: SELECT .. FROM WHERE AND
model.modelName LIKE '%a%';DELETE * FROM model;SELECT * FROM model WHERE
something LIKE '%a OR VARIANT
You can't trust incoming variables.
Yeah, I know ... this code was from before I learned how to check and
escape form fields though, just didn't put the error checking/correction
into the code yet ... haven't worked on this thing for like a year cuz I
got sick of it after putting the several hundred rows manually into the
database. I wrote this script originally before I knew anything about using
relational tables in SQL, I simply just changed the query code to use the
relations instead, and that's when it died.
That said, the query worked when being put directly into a MySQL prompt,
albeit extremely slow and far beyond what's normal. But I gave up trying to
fix it as I couldn't find the problem, so I dumped the entire query part of
the code, and started over with new code, from another script that uses the
same tables, but have never caused me any problems ... and it works now.
And almost 10 times faster than before. It can pull the entire 882 rows,
and generate the entire page, in 12 seconds. And all I did was use a
different query as basis, write completely new query generating code from
scratch, and add some functionality to the form ...
I haven't added the LIKE part to the new code, but I've changed the field
select boxes to multi-select instead of single-select, and the order
picking now lets you choose 3 orders, instead of just 1, so the code's a
bit different now. I know it looks like it does some double-checking of the
same thing, but it's to be damn sure it doesn't run the code parts unless
it has to. And the code works, and much, much faster than the old one. In
fact it takes it longer to ship the data over my network than it takes the
server to run the script. I don't get why it's so much faster now, as
there's very little difference in the query, but it does, and it's all I
really wanted. It still needs some fine-tuning to handle the addslashes and
such, but I haven't gotten to it yet.

[PHP-DB] Why does this code/query hang time out ?
Hi gang
My CPU database (http://metalbunny.net/computers/cpudb.php) - still a work
in progress - used to be in 1 table, but for several reasons I've decided
it's better to split the data into multiple related tables. Obviously this
means I have to rewrite the query tool for it, and that's where my problem
lies. I've included the code I'm working with below, it's a little
different than the one for the above URL, as it uses my new faster
templates and relies more on the database than the old code did.
All the DB connect stuff is in the template, and I use MySQL. The new
version isn't available online, it's only on my local development server.
I'm pretty sure it's simply a coding problem, but for the life of me I
can't find anything that looks wrong ... but then I've been staring at it
for hours...
My problem came after I tried making it possible to pick 'all' as a search
option in make model, and now, nomatter whether it's set to all or not,
and nomatter what's in the search field, the code stalls and hangs ... and
in the last tries, Firefox ended up closing down ...
I tried putting athlon in the search box, and just leave everything on
default, and the generated query looks like this:
SELECT
make.makeID,makeName,model.modelID,modelName,fsb2,socket.socketID,socketName,cpuID,variant,clock,multi,fsb,l1,l2,l3,vcore,vcache
FROM cpu_maker AS make,cpu_model AS model,cpu_socket AS socket,cpu_cpus AS
cpu WHERE make.makeID=model.makeID AND socket.socketID=model.socketID AND
cpu.modelID=model.modelID AND model.modelName LIKE '%athlon%' OR `variant`
LIKE '%athlon%' AND make.makeID0 AND socket.socketID0
Leaving the search box empty produces no result - it's an unintended
leftover from the old code that I haven't found a good way to get around yet.
The code I'm working on looks like this (beware, it's rather long):
?php

Hi gang
I'm in need of, if at all possible, cutting down the processing time for
sending messages to multiple recipients with my insite messenger. The
current version runs 1 query to get the names of all recipients, then 1
query per recipient, and then 1 query to deliver a copy to the sender.
The code in question is below. $userID and $username is the current user,
and are set by the login system much further up. $_POST['rcvID'] is a
multi-select select box where the user can choose which users to send the
message to. The rest should be pretty obvious. I use a couple flags on the
messages so the system can tell received and sent messages apart in the
message boxes.
// add slashes as needed
if (! get_magic_quotes_gpc()) {
$subject = addslashes($_POST['subject']);
$message = addslashes($_POST['message']);
} else {
$subject = $_POST['subject'];
$message = $_POST['message'];
}
// get names of recipients
if (count($_POST['rcvID']) 1) {
$where = `userID` IN('.implode(',',$_POST['rcvID']).');
} else {
$where = `userID`='.$_POST['rcvID'][0].';
}
$rcvquery = SELECT userID,nickname

$rcvdata = mysql_query($rcvquery) or die('Unable to get recipient

your databes lags normalization!!!
My lack of normalization is open for debate, the tables are designed this
way to suit the flexibility I need ... the reason I have the ownerID in the
table is simply to make the code easier for me to read. I do know it's not
strictly needed because I can find the right owners by using the read and
sent flags, but it made the code harder for me to read when I did it like
that. Because this project is nowhere near finished, I need to keep the
code a little easier to read, at the cost of a little performance. I'm
aware that having the to/from names with the messages don't look
immediately like a good idea, because it adds apparently superflous data to
the table, but it serves a specific purpose. If I didn't have the names
with the messages, then I'd have to use joins to get those in when pulling
the messages from the database. That in itself isn't the problem. The
problem comes with deleting users. If a user is deleted, there's no
information to attach to the corresponding ID in the message, and thus the
join would omit any messages sent to/from users no longer in the system,
and in the case of userID recycling, there's the risk of it appending the
wrong username to the message.
The sheer number and size of the fields in the userprofiles in this system
makes it unpractical to simply mark them as deleted when deleting them. It
would mean a serious waste of diskspace that goes beyond what the little
lack of normalization in this one table causes. I have the username
fallback fields in 3 of 14 tables, with the planned design that will
eventually become around 20-22 total tables, because of alot of needed
cross-linking between tables. It goes back to the practicality of not
keeping user profiles in the system for any other purpose than making joins
work.
I'm by far not an expert on neither PHP nor SQL or database design, and
never claimed to be. I learned to program when I was 8, in Basic, and
learned about databases by fooling around with MS Access. It's been 20
years, and till last fall I've mostly never touched creating or designing
databases at all cuz I've mostly worked with the HTML side of things, and
otherwise only done coding for databases made by others, where I've had no
say in how the database was organized.
Everything I do these days is about learning how to push the limits of what
the code and the database allows. And to learn how to get the functionality
I want in the most efficient and practical way. Slandering my work will not
do me any good. If you wanna come with constructive criticism that's fine,
but have you ever considered that there are reasons for everything ? If you
don't know the reason for the design choice, or the whole picture, any
criticism you make will always and only be objective, and not constructive.
But most the entire database have fields cut back to make the normalization
as great as possible. I'm still largely working on getting all the
functionality working primarily, and thus I'm still doing some
experimentation with the database design, as in what fields I need and
don't need to do what I need to do. The 3 tables that aren't fully
normalized contain posts and messages in various forms. For the simple
reason of being able to display those posts/messages, and do so with the
correct original username, I slack a little on the normalization to make
that work.

RE: [PHP-DB] Book recommendation for using MySQL w. PHP
Thanks Rich I'm aware of that problem, but without getting my hands on the book it's a little hard to see if it covers my needs. It's the same with my PHP books ... everyone told me to get Sterling Hughes' PHP Developer's Cookbook, but beyond the chapter on constructing and using objects, and a little bit in the regular expressions part, I've not really had any use of that book at all - it simply does not cover the kinda stuff I work with... It was cheap enough though, so I'm not complaining, but alot of the things it covers aren't done deep enough for my needs. I'm sure there are others that could find more use of it, but for me it's limited... Undoubtfully the same with books on other parts of the coding ... most my C++ books are pretty useless, same with the ones on alot of other things.

[PHP-DB] Using an array(-ish) in SQL queries
X-posted to MySQL and PHP DB Hi gang Task at hand: deleting or selecting (same difference) several numbers of records using only 1 query. My first version simply looped through all the ticked off IDs and ran a single query for each delete routine. I've still not suceeded in getting the delete queries to work on multiple tables at once, despite the column names being the same. But besides this: My current version generates, for multi-select cases, queries like this: DELETE FROM the_table WHERE `ID`='1' OR ID`='2' OR `ID`='3' OR `ID`='4' OR `ID`='5' OR `ID`='6' or similar with the SELECT statement. On some occasions this can result in a very large amount of OR statements, like for 50 IDs totally. I've been reading through the MySQL manual and the comments in the select and delete parts, but cannot seem to find any mentioning of an easier way to do this. Or it's been deluting me cuz English is my second language, so the MySQL manual doesn't always make much sense to me. I'm looking for something like passing on an array (as comma-seperated-list maybe), and then just do statements like: DELETE FROM the_table WHERE `ID` ISIN(1,2,3,4,5,6) Did I totally miss that part of the manual, or is it just not possible with MySQL ? Now, for my script it doesn't really matter much which approach to use, but was more thinking performance wise it ought to be faster and less taxing for the server to parse an SQL statement that's closer to table structure, rather than the OR statements that has to be transformed first. Sorry if I'm just a blind mouse that can't seem to find things in the MySQL manual. It's not really my best friend...

If you know all the values in the array are escaped and safe you can just
use implode() to make the list for IN
$string = implode(',',$array);
$sql = SELECT FROM $table WHERE col_name IN('$string');
Notice I added single quotes around the string, that is because they will
be missing since implode only sticks the string between array elements.
However, you'd need a join that makes sense for a multi-table delete. I
don't know if it will work with a union, I have never tried, maybe somone
else will chime in.

[PHP-DB] How do I reverse-finding root entry in tree-structure ?
Hi gang This is possibly insanely simple, but I've been coding on it for the past 11 hours, so my head's gone a little fuzzy. been through the MySQL manual, but it's not really agreeing with me on finding anything useful... I've got a table of categories, organised in a tree structure: table wp_categories catID int(10) UNSIGNED parentID int(10) UNSIGNED rootID int(10) UNSIGNED level tinyint(3) UNSIGNED cat_title varchar(255) cat_desc text catID being the primary key, parentID the parent's ID, and rootID the ID of the root category of the branch this category belongs to. Level is simply a number as to how deep in the tree the given category is. I only use it to make it simpler to build the graphics. Here comes the problem: I need to be able to build visually the branch from root to a given folder, using only the given folder's ID as starting point. That is, traversing backwards up the branch from any given folder, and reattaching the branch till the root is reached. Building the entire tree from root down is easy enough, but for some reason I've got a brainfart as to how I can go backwards. That said, I know I could probably do this using recursive SQL statements, but I'd rather use as little talking with the DB as possible. The goal is to do this one task with as few SQL calls as entirely possible, preferably 1, 2 at most... since I found building arrays and traversing them is much faster than SQL calls... the root ID is 0, so any category in root, will have parentID of 0, and rootID of 0. I figure using the rootID to just pull the relevant branch might be part of it, but my problem comes with reattaching the branch correctly, and finding the root folder and stick the branch to it ... and doing all of this in reverse since that's what I need for the visual part... Using MySQL btw ... TIA Rene -- Rene Brehmer aka Metalbunny If your life was a dream, would you wake up from a nightmare, dripping of sweat, hoping it was over?

Re: [PHP-DB] MySQL max records
How many records it can hold before becoming too slow for practical use depends entirely of the hardware that makes up the server. Current versions of MySQL has a finite limit of 2^64 records per table, but how many billion records you can shove into it before you start seeing performance issues depends on the RAM size, the RAM/CPU roundtrip speed, and the pure processing power of the CPUs, as well as the overall load of the server. Obviously dedicated DB servers/clusters will be able to handle alot higher record counts than mixed-purpose servers.

queries on the same page.
$records = mysql_query(SELECT COUNT(*) AS count FROM persons) or
die('Unable to get record countbr'.mysql_error());
$totalcount = mysql_result($records,0) - 1;
$rndrecord = rand(0,$totalcount);
$personquery = mysql_query(SELECT personID FROM persons LIMIT

[PHP-DB] MySQL: Problem optimizing multi-table row deletion ... errors out :(
hi gang
I'm working on optimizing the SQL for my forum system, but have run into a
problem trying to optimize the function for deleting a thread with
accompanying stats data and posts from the database using 1 query.
The current function, that works, looks like this:
// delete all traces of a thread
function delThread($threadID) {
$result = mysql_query(DELETE FROM hf_threads WHERE
`threadID`='$threadID');
$result = mysql_query(DELETE FROM hf_thread_stats WHERE
`threadID`='$threadID');
$result = mysql_query(DELETE FROM hf_posts WHERE `threadID`='$threadID');
}
I went through the MySQL manual, to try and find a way to optimize this,
and came up with this variant:
// delete all traces of a thread
function delThread($threadID) {
$result = mysql_query(DELETE FROM hf_threads,hf_thread_stats,hf_posts
WHERE `threadID`='$threadID') or die('Unable to delete
threadbr'.mysql_error());
}
only it doesn't work at all ... the error output says this:
Unable to delete thread
You have an error in your SQL syntax near 'hf_thread_stats,hf_posts WHERE
`threadID`='85'' at line 1
(Obviously I attempted to delete the thread with ID 85 here)
I'm dealing with MySQL 3.23.56-log and PHP 4.3.0 ...
Any ideas for optimizing this will be greatly appreciated, esp since I'm
not all that great with the more complex SQL syntax...
TIA

[PHP-DB] Handling missing rows on joins
Working with PHP 4.3.0 and MySQL 4.0.14 (but code MUST be compatible with 3.23.56). For my forums, I've got this 4-way join to load (and output) the posts with info on the poster: $fullthread = SELECT postID,hf_posts.userID,name,time,post,edit,nickname,joined,location,posts,levelname FROM hf_posts,hf_users,hf_user_stats,hf_levels WHERE hf_posts.threadID='$threadID' AND hf_posts.userID=hf_users.userID AND hf_user_stats.userID=hf_users.userID AND hf_levels.levelID=hf_users.levelID ORDER BY hf_posts.time ASC; I'm not gonna paste the entire table structure, cuz it comes to rather many rows those 4 tables make up. But it's pretty basic really: hf_posts contain the posts in the forum. hf_users contains the static userinfo = the user's profile, level assignment and a few control values. hf_user_stats contains the dynamic user info - number of posts threads, last login and logout, last IP, and things like that. hf_levels contains information and general perms for the user levels. hf_posts has postID as primary key, and threadID and userID as foreign keys. hf_users has userID as primary key, and levelID as foreign key. hf_user_stats is basically an extension of hf_users, and thus only have userID as primary key, but it also functions as foreign key. hf_levels has levelID as primary key, and no foreign keys (it's a top-level table in the relations). The way it's made, when a post is made, the poster's userID and displayname is stored in hf_posts under 'userID' and 'name' respectively. But the poster's current displayname is always in hf_users.nickname. Posts by unregistered users (or those not logged in) are stored with userID 1. Since the system allows unregistered users to post, I've got a guest user implanted into the hf_users table on ID 1, just so the join won't fail to display those posts. When the script outputs the posts, it checks the userID of the posts. If the userID = 1, then it prints the displayname stored with the post, and skips the userdata for that post, otherwise it uses the displayname from the users table. But here comes the problem: If a user is deleted, the records from hf_users and hf_user_stats will be gone. On the join, this means that any posts made by the deleted users will not be included, and thus not displayed -- they become dangling posts in the database ... I haven't actually written the code to delete users yet, but my current idea for a workaround is that on deleting the users, changing all their posts to userID 1 (the system guest level). This would atleast let the posts be displayed, although make those posts display as posted by a guest, and because the displayname is stored with the post, it would not list as Visitor/guest. What I have problem with is figuring out whether this is a kludge or the only way to do it. Or is there a better way to make the join so it will include the posts even if it cannot find anything to join with in hf_users and hf_user_stats ??? I know it looks like deleting levels will cause problems as well, but the code for that has been made so deleting a level will move all users assigned to that level to a different one.

[PHP-DB] How to get only 2nd row in result set ???
I couldn't find anything like this from my archive searches ... so here goes:
I've got this query:
$levels = mysql_query(SELECT levelID from hf_levels ORDER BY levelorder
DESC LIMIT 2) or die('Unable to get levelsbr'.mysql_error());
but I can't figure out how to write the rest of the code ... I need to skip
the first row and get the data from the 2nd row... but because there's an
optional up to 255 possible rows in this table, and the order of these are
determined by a user customizable field called levelorder ... so I can't
just pick the specific numrows - 1 ... :-/
I know this is a kludge to do it this way ... but it's what I need for now
... later I'll get to do it a more brilliant way...
TIA

[PHP-DB] What's the difference here????
Hi gang
I ran into a minor, but weird problem yesterday ...
Query one:
$catpermsquery = mysql_query(SELECT cat_view FROM hf_category_perms
WHERE `catID`='$catID' AND `levelID`='$levelID' LIMIT 1) or die('Could not
get cat perms'.mysql_error());
$catperms = mysql_fetch_array($catpermsquery);
$cat_view = $catperms['cat_view'];
$perms = mysql_fetch_array(mysql_query(SELECT may_view FROM
hf_level_perms WHERE `forumID`='$forumID' AND `levelID`='$levelID' LIMIT
1)) or die('Unable to get permsbr'.mysql_error());
$may_view = $perms['may_view'];
Both queries are on the same page ... the first one makes the script
determine whether or not to run the query that generates the loop where the
second query is inside ...
If I write the first query like the second one:
$catperms = mysql_fetch_array(mysql_query(SELECT cat_view FROM
hf_category_perms WHERE `catID`='$catID' AND `levelID`='$levelID' LIMIT
1)) or die('Could not get cat perms'.mysql_error());
Then all it displays is my error message: Could not get cat perms ... and
no MySQL error message. I cut it up like above, and it works fine.
All I really wonder about is WHY it behaves like this in one query, but not
the other
the two tables that are used in here have similar structure, one primary
key, ID, that's merely an auto-increment that I don't use for anything but
the required indexing, then catID in the first table, forumID in the
second, and levelID in both. For each combo of levelID and catID/forumID
there's 1 row in each table. The only structural difference is that the
second table has 10 more fields than the first one...
This is the only time I've had a problem with putting
mysql_fetch_array(mysql_query()) inside each other ... some of the queries
I naturally have to split because I need to check if there's any result
returned from the query ... but with these perms query the data they look
for will always exist (unless MySQL makes a mistake and dumps a row without
being told to), because they're only run inside other queries that look for
the respective catID/forumID these uses, so they won't be called unless
that particular category/forum exists. So there shouldn't be a problem
combining the two statements into 1 ... (other than it not exactly being
textbook coding :p )
TIA

[PHP-DB] Looking for simpler way to do this...
I'm working with PHP 4.3.0 w. MySQL 4.0.14b on Windows XP
I've written my own (pretty advanced actually - or it will be once I get
the code completed) forum system (why? because I wanted to learn how to
handle relational databases with PHP/MySQL, and then I just decided to
complete the thing) ... it uses a multitude of 1-to-many relations across
several tables, to keep track of categories, forums, threads, posts, perms,
users and so on ...
This particular chunk of code is part of the show forum code. What the
first query does is pull out all the threads in the current forum ($forumID
... this valuable is set further up the code), and all the posts in each
thread to find the last post in that thread.
The second query is simply to figure out how many posts are in each thread.
If at all possible, I'd like to combine these two query pulls (to keep the
number of DB pulls per page down - there's currently 1 more, but going to
be 2-3 more queries on this page than just this), but since I'm still
rather n00bish at the SQL statements, I can't figure out how...
Code in question:
// get all the threads in current forum, and for each thread find the last post
$threadquery = SELECT * FROM hf_threads,hf_posts WHERE
hf_threads.forumID='$forumID' AND hf_posts.threadID=hf_threads.threadID
GROUP BY hf_threads.threadID ORDER BY hf_posts.time DESC;
$threads = mysql_query($threadquery) or die('Error in thread
querybr'.mysql_error());
while($thread = mysql_fetch_array($threads)) {
// info from hf_threads
$threadID = $thread['threadID'];
$threadtitle = $thread['threadtitle'];
$threadmaker = $thread['createnick'];
$threadstart = $thread['createtime'];
// info from hf_posts
$lasttime = $thread['time'];
$lastposter = $thread['name'];
// number of posts in thread
$threadposts = mysql_fetch_array(mysql_query(SELECT COUNT(`postID`) AS
numposts FROM hf_posts WHERE `threadID`='$threadID')) or die('Threadposts');
$numposts = $threadposts['numposts'];
// output thread data
echo(tda
href=\showthread.php?forumID=$forumIDthreadID=$threadID\$threadtitle/a/td);
echo(tdbBy:/b $threadmakerbrbAt:/b $threadstart/td);
echo(td align=\center\a
href=\editthread.php?forumID=$forumIDthreadID=$threadID\Edit/a/td);
echo(td align=\center\$numposts/td);
echo(tdbAt:/b $lasttimebrbBy:/b $lastposter/td\n);
echo(td align=\center\input type=\Checkbox\
name=\del$threadID\/td);
echo(/trtr\n);
}
Structure of tables in question:
#TABLE hf_threads:
threadID // ID of current thread
forumID // ID of forum where the thread belongs
userID // ID of thread creator (for perms reasons)
createtime // time of thread creation
createnick // name of thread creator
threadtitle // title of thread
sticky // not implemented yet
closed // not implemented yet
#TABLE hf_posts:
postID // ID of post
threadID // ID of thread where the post belongs
userID // ID of poster (for perms reasons)
name // name of poster
time // time of post
post // actual post content
edit // tracking data of editings
not that it's really relevant in this case, but these 2 tables are through
the relations tied together with 8 other tables handling the forums and
perms and users and statistics and such ... that's the reason why I want to
keep the number of queries down, as it has to do join searches on a couple
of these to handle the perms and other things on each page...
TIA

[PHP-DB] how to do query on partial field contents ???
hi gang
I've mentioned this project before a couple of weeks ago ... just been busy
with school, so haven't had time to work on it that much
But anyways ... the test version is running here:
http://metalbunny.net/computers/cpudb.php
it's running with debug code, which should be obvious if you test it ...
It's MySQL database ... testes it on both my webhost and my local test
server, result is the same.
If you fill in the search field and click the search button, I want it to
list all records where the fields partially matches... but as it is now, it
will only list records where the entire field matches. That is, if you
search for Athlon, it will only list those where a field exactly is
Athlon, whereas I want to list Athlon, Athlon XP, Athlon MP, and so
on ...
Figure that it would require some sort of wildcard, but the traditional
ones I've tried didn't work, so I'm at a dead end once again...
This is the 90 lines of code that generates the queries. Probably room for
improvement, but then I'm no expert at this:
$query = 'none';
$basequery = 'SELECT * FROM cpu';
if (isset($_GET['search'])) {
$query = $basequery.' WHERE cpuID 0 ';
$setorder = true;
$query .= AND `model` LIKE '.$_GET['search'].'; // this block split
for debug reasons
$query .= OR `variant` LIKE '.$_GET['search'].';
$query .= OR `type` like '.$_GET['search'].';
}
else if (isset($_GET['make']) || isset($_GET['model']) ||
isset($_GET['socket'])) {
$query = $basequery;
$setorder = true;
if ($_GET['make'] != 'All' || $_GET['model'] != 'All' || $_GET['socket']
!= 'All') {
$query .= ' WHERE ';
if ($_GET['make'] != 'All') {
$query .= `make`='.str_replace('+',' ',$_GET['make']).';
}
if ($_GET['make'] != 'All' $_GET['model'] != 'All') {
$query .= ' AND ';
}
if ($_GET['model'] != 'All') {
$query .= `model`='.str_replace('+',' ',$_GET['model']).';
}
if ($_GET['model'] != 'All' $_GET['socket'] != 'All') {
$query .= ' AND ';
}
if ($_GET['socket'] != 'All') {
$query .= `socket`='.str_replace('+',' ',$_GET['socket']).';
}
}
$linkquery = str_replace('
','+','make='.$_GET['make'].'model='.$_GET['model'].'socket='.$_GET['socket']);
}
if ($setorder) {
switch ($_GET['order']) {
case 'socket':
$query .= ' ORDER BY socket';
break;
case 'form':
$query .= ' ORDER BY form';
break;
case 'vcache':
$query .= ' ORDER BY vcache';
break;
case 'vcore':
$query .= ' ORDER BY vcore';
break;
case 'l2':
$query .= ' ORDER BY l2';
break;
case 'l1':
$query .= ' ORDER BY l1';
break;
case 'fsb':
$query .= ' ORDER BY fsb';
break;
case 'multi':
$query .= ' ORDER BY multi';
break;
case 'clock':
$query .= ' ORDER BY clock';
break;
case 'type':
$query .= ' ORDER BY type';
break;
case 'variant':
$query .= ' ORDER BY variant';
break;
case 'model':
$query .= ' ORDER BY model';
break;
case 'make':
default:
$query .= ' ORDER BY make';
break;
}
switch ($_GET['ad']) {
case 'd':
$query .= ' DESC';
break;
case 'a':
default:
$query .= ' ASC';
break;
}
}
The order part is of course not that relevant in this case, but I left it
in the snip for the variables set in the query part to make sense...
Question is simple: What do I change in the code to make it do partial
field matches, instead of complete ???
Hoping for help :) ... TIA

Re: [PHP-DB] PHP and mail forms
I wrote mine specially ... it runs with a preview phase which was pretty
tricky to put in ... but the to-value is hardcoded in the script, cuz it
just sends mail to [EMAIL PROTECTED] ... when the user fills in the
form the script checks it for errors, and then either bounce back to the
form if there are any errors, or to the preview if there's not (atleast I
think I kept the preview in there, not sure anymore, been a long while)
and then on to a thank you message
I control it all using hidden form fields ... pretty simple ... it's coded
to my old site-structure, before I started to use templates ... so it's a
bit difficult to peel it out and show it to you though but will try if
requested...

Some people like the approach:
if ($submit) { send_email(); }
or you can put a hidden field in your form, like op:
input name=op type=hidden id=op value=send /
and use:
if (isset($HTTP_GET_VARS['op']) ($HTTP_GET_VARS['op'] == 'send'))
{
send_email();
}
and there are many others.
by the way in the code you wrote you have:
form method=post .
and then you use:
$id=$_GET['id']; --- if this is the same than $HTTP_GET_VARS['id'] this
wont work
Where does that mail function (is it a function?) go?
The function sends an email, for more details consult the php manual.

hi gang okay, freeform may not be the right term, but dunno what else to call it...

But I have no idea what a query for that looks like ... none of my references do something like that Basically ... if you search for athlon, it should be able to find Athlon, Athlon XP, Athlon MP, and Athlon64 ... (which are all in the model field) ... or like you enter Thunderbird, and have model,variant, and type checked, it will be able to list only those that have Thunderbird in the type field... also ... how do I do range searches ... like listing all speeds from 500 to 1000 or something like that ??? yeah, I seriously need some decent documentation for constructing SQL search strings TIA Rene -- Rene Brehmer aka Metalbunny http://metalbunny.net/ References, tools, and other useful stuff... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For all users I create in the 'user' table in 'mysql' DB, if I set a password, that user becomes unable to access any DBs ... it doesn't matter if I set the pw as ASCII or password, still won't allow access... I've tried making new users and copying all settings of the default root user (which I've not set a PW for cuz I loose access to the main DB when I do that) ... nomatter what, all users can access the DBs fine when no pw is set, but if a pw is set, MySQL reports access denied... and yes, it actually also does this when using the MySQL command line tools which makes it even weirder... This is a single-user test setup for development use only ... I run MySQL 4.0.14b on Windows XP Pro SP1 ... with Apache 2.0.48 and PHP 4.2.3 on CGI. Doesn't matter what kind of DB access I try; the MySQL binaries, PHPMyAdmin, custom made PHP/MySQL apps, or PHPBB ... if I set a PW for a user, that user becomes unable of accessing the DBs ... I've tried opening up the firewall for the MySQL server modules to access the Internet, but does not make a change ... hostname is set to 'localhost' in the mysql table (since all it has to work with are connections from the same windows session anyways)... is there any other place in the mysql table that I have to add/change stuff than 'user' to get this to work??? so lost here ... any help appreciated (and as far as I can tell, I've done every step in all MySQL install guides I could find ... atm I'm running on a restored version of the default mysql DB with the % users set ... since the firewall locks out remote access, I didn't think it's a big deal)... n00b at SQL TIA Rene -- Rene Brehmer aka Metalbunny http://metalbunny.net/ References, tools, and other useful stuff... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] MySQL: How to properly extract fields from retrieved single record ???
Hi gang
Still working on this DB for my gameclan not that it's essential what
it's for... and be warned: Never worked with any form of DB in PHP before I
began this project, so I'm a total n00b at these MySQL commands (and the
manual for MySQL is by far nowhere near as good as the PHP one).
Anyways, I'm retrieving a single record from the DB table, and then,
because of the way the data needs to be displayed and manipulated, need to
extract every single field from that record as a seperate value.
I tried this:
$num2edit = $_POST['edit'];
$link = mysql_connect($host,$username,$password)
or die('Could not connect : '.mysql_error());
mysql_select_db($database) or die('Could not select database');
$query = SELECT
countryNum,country,nw,gov,strat,spy,troops,jets,turrets,tanks,ally,owner
FROM a2a WHERE countryNum=$num2edit;
$result = mysql_query($query);
$countryNum = mysql_result($result,1,'countryNum');
$country = mysql_result($result,1,'country');
$nw = mysql_result($result,1,'nw');
$gov = mysql_result($result,1,'gov');
$strat = mysql_result($result,1,'strat');
$spy = mysql_result($result,1,'spy');
$troops = mysql_result($result,1,'troops');
$jets = mysql_result($result,1,'jets');
$turrets = mysql_result($result,1,'turrets');
$tanks = mysql_result($result,1,'tanks');
$ally = mysql_result($result,1,'ally');
$owner = mysql_result($result,1,'owner');
/* Free resultset */
mysql_free_result($result);
/* Closing connection */
mysql_close($link);
But all it gives me are errors like this:
Warning: mysql_result(): supplied argument is not a valid MySQL result
resource in E:\web\mpe\a2aedit.php on line 350
Warning: mysql_result(): supplied argument is not a valid MySQL result

Obviously, the first mysql_result line is line 350 in the full code. I've
also tried changing the row number to 0, but results in the same errors.
I can't find any decent reference on the web that shows how to do this -
field extraction - when there's only the single record. So I've been mixing
code from various places. And I don't even know if it retrieves the right
record, or any record at all (how do I test that?).
Any help is highly appreciated :)
TIA

Re: [PHP-DB] How to do error feedback when adding to indexed table?
Sorry if I was being vague. But naturally, about half an hour after I
posted this, I found a simple and fool-proof way to do what I wanted:
Simply just have MySQL lookup the ID after all the other error checking was
done, like this:
if (! isset($error)) {
// DB check to ensure number is not already in DB
// only do this if no other errors are present, because it consumes more
// resources and time.
$link = mysql_connect($host,$username,$password)
or die('Could not connect : '.mysql_error());
// echo('Connected successfully');
mysql_select_db($database) or die('Could not select database');
$query = 'SELECT * FROM ally2ally WHERE id='.$_POST['num'];
$result = mysql_query($query);
$numrows = mysql_numrows($result);
if ($numrows 0) {
$error = 'The country number you entered already exists in the
database. To edit an existing entry,
please use the edit tool/function.';
}
Well, this is a simple way to me atleast. This is run after initial prost
procedure, and after all the other error checkers, so that it can bump it
back to the edit form without going through the preview first.
Thus I managed to figure it out on myself, although going about it quite
differently from what I originally thought I had to. So, I'm so sorry for
wasting everybody's time with this.
Should perhaps be said that the edit tool mentioned in the code above
isn't coded yet, so I might come back to you nice people once I get to that.
But, to answer Sebastian's questions:

Is that your Primary Key? Does this ID have a meaning to you, or is it
random?
Yes it is primary, and yes it has meaning. Each player in the game have a
single country. Each country have a unique number, generated by the game.
We use these numbers to indetify the countries, and thus it's only natural
to use it for the same purpose in my database.
Whenever someone wants to add data to the table, they fill out a form, hit
submit and either get an error about wrong or missing data, or if ok get a
preview before being able to finally add it to the table. As the script is
now, it will attempt to add the data to the table, but if already there,
nothing happens, and there's no response to the user about it.
Do you mean if the ID is already there?
Yes.
The rest of the code is not essential in this aspect. I just need some
help
to figure out how to make the script tell the user that it can't add the
data because the ID is already in the database...(that's the first field
btw).
I'm still not sure what exactly you want to do. But usually you make your
ID an AUTO_INCREMENT. That way you don't have to worry about giving the
same ID twice.
I am aware that :-). Problem here is that the information stored in the
database must match the content of the game, and therefor also use the same
ID numbers. I should probably have mentioned that in my initial posting,
sorry. The country we store information about, may only exist once in the
database, therefor I use the country's number as ID. If I used an
auto-incremented ID, it would be possible to enter the same information as
many times as one would like, which is not desirable.
If you don't know the game, I do realise that understanding what I talk
about may be a bit difficult. I apologize for that. But if anyone have
anymore questions to this project, I'll happily ask them. If it's about the
game, better keep it offlist, thank you.
Thanks for the help

[PHP-DB] How to do error feedback when adding to indexed table?
I'm not sure how to explain this, I'm totally new to MySQL and SQL as a
whole, this is my first ever code using SQL at all...so plz bare with me
here...
I'm working with PHP 4.2.3 and MySQL 4.something (not certain what version
the end-server runs).
For a game clan I'm in (MPE 1A in Earth: 2025 - 1a), I'm working on a DB to
store some rather game-specific info. It's only a single table in the DB,
but the table is indexed by the field 'id'.
Whenever someone wants to add data to the table, they fill out a form, hit
submit and either get an error about wrong or missing data, or if ok get a
preview before being able to finally add it to the table. As the script is
now, it will attempt to add the data to the table, but if already there,
nothing happens, and there's no response to the user about it.
I want it to give a feedback message that the data is already in the table,
and bump ppl back to the edit form with that message. For the other things
the script checks, all it does is load the variable $error with the
error-message and set a phase-flag to the right value, and then the page
generation part knows that there's been an error, and regenerates the entry
form with the submitted data. So what I want, is to have the add data part
to just change the two variables needed for the error system to see there's
something wrong, but I've got no idea what I need to change in the code to
do that. I've searched google and the archives, but come up with nothing...
Here's the add-data part of the code...the variables in the comment is just
so that I know what kind of data are in each variable, rather than what
they're actually set to in the DB:
elseif ($phase == 3) {
/*
num / id = int
country = string
nw = int
gov = string
strat = string
ally = string
spies = int
totdef = int
totoff = int
owner = string
*/
mysql_connect($host,$username,$password);
@mysql_select_db($database) or die('Unable to select database');
$query = INSERT INTO ally2ally VALUES
('.$_POST['num'].','.$_POST['country'].','.$_POST['nw'].','.$_POST['gov'].','.$_POST['strat'].','.$_POST['spies'].','.$_POST['totdef'].','.$_POST['totoff'].','.$_POST['ally'].','.$_POST['owner'].');
mysql_query($query);
mysql_close();
}
the error message part is simply this:
?php
// if there is an error in the submitted data, display the error message
if (isset($error)) {
?
table
tr
td?php echo($error); ?/td
/tr
/tablebr
br
?php
}
?
The rest of the code is not essential in this aspect. I just need some help
to figure out how to make the script tell the user that it can't add the
data because the ID is already in the database...(that's the first field btw).
TIA

[PHP-DB] Compiling 4.2.3 with MySQL ... what does it look for?
X-posted to PHP General, PHP DB, and MySQL Hi gang Attempting to get my Linux test-server working, but ran into a problem when making PHP... System is RedHat 8, Apache 1.3.27 (compiled myself, tested OK), MySQL 4.0.13. The Apache 2.0.40 and PHP 4.2.2 that came w. RH8 didn't work correctly, thus I've ventured into my own creation. Trying to build PHP 4.2.3 (because that's what my webhost runs, so need that version to test correctly) w. support for MySQL. Running ./configure --with-mysql=/[path to mysql] --with-apxs=/[path to apxs] Found the path to the apxs to be /usr/local/apache/bin/apxs, but for the life of me I cannot figure out what path to give it for MySQL. I installed MySQL from the the RPM files: MySQL-client-4.0.13-0.i386.rpm MySQL-devel-4.0.13-0.i386.rpm MySQL-embedded-4.0.13-0.i386.rpm MySQL-server-4.0.13-0.i386.rpm MySQL-shared-4.0.13-0.i386.rpm client and server first, the rest second ... used --force to get them in, because it complained about version issues with the one already there (even though the package manager was told not to put the Mysql in, it still put MySQL 3.something in...) When doing the configure above, I get this error: configure: error: Cannot find header files under /usr/include or whatever path I give it ... I'm having a hard time figuring out where the RPM puts everything, and an even harder time figuring out what path to stick to PHP ... Some detective work gave me these paths: MySQL (bins): /usr/bin /usr/share/mysql MySQL daemon (mysqld): /usr/libexec /usr/sbin MySQL headers (.h): /usr/include/mysql I've tried them all, but they all result in the above error. Anyone care to guess which path I should give to the configure? Or is it something else that causes this? I haven't ever used MySQL before, or any other SQL for that matter, so got 0 experience in getting the system up and running with it...

[PHP-DB] Re: [PHP] Headers in body - what am I doing wrong???
At 22:48 11-06-2003, you wrote: You are already pretty far in determining the problem. Indeed the border between the header and content of a mail is an empty line. What if i just give a hint? Look closely: $from = \$name\ $address\r\n; $headers .= From: .$from.\r\n; See ? Yup ... too many header fields, and just one that ain't ... so hadn't noticed it ... PS some mailservers do not like \r\n, check the manual on mail() and see what they suggest, i think it was just \n. I actually wrote this according to the manual, ... this is an extract of the offline version of the PHP 4.2.3 I've got: Multiple extra headers are separated with a carriage return and newline. Note: You must use \r\n to seperate headers, although some Unix mail transfer agents may work with just a single newline (\n). Sounds like you're reversed there ;-) Mercury only cares about whether or not it's conformant to RFC822 and the siblings. Anything non-compliant is simply ignored or discarded ... but my webhost use sendmail on Linux, and since I've got another mailscript that uses the same basic format, and it works exactly as intended, then I don't think it's a problem with the \r\n header seperators... Thanks to y'all ... now I just gotta figure out why Mercury doesn't process the commands. ... commands sent by regular mail are processed ... so it must be a problem with the script...
