RE: [PHP-DB] Another dynamic sql.
Seems like it will NOT work because you are selecting $car which is already
chosen by the user (i.e. which is a known value). I don't know how you laid
out your table but shouldn't your query be something like "SELECT price from
FROM varetabell where carid=$car" ??

Subject: [PHP-DB] Another dynamic sql.
Hi all!
I have this form with some choices:
Enter how many cars you want:
ford
bmw
mercedes
And then I am trying to get the price out of a table in my database with
this code:
$sql = mysql_query("SELECT '$car' FROM varetabell where carid='$carid' ");
$myrow= mysql_fetch_array($sql);
$x = $myrow["$car"];
$price = $x * $number;
Shouldn't this work? Or am I missing something here?
Best regards Raymond

RE: [PHP-DB] fwrite()
You don't have anything to write to the file.. mysql_query() function
returns true or false, it doesn't return the actual qurey result you'd see
in mysql monitor. You have to use some other functions such as
mysql_fetch_array(), mysql_num_rows() to retrieve the data before you can
write it into a file.

RE: [PHP-DB] fwrite()
Jamie,
The main problem here is , you are selecting the rows that are some null
values. mysql_fetch* doesn't return any null columns. Yes, you read it
right, if you have a table with say, 5 columns and if 3 columns in a row are
null then you'll only have 2 columns that are not null .
Make sure that this is not causing any problem for you.
What does your table look like and and what values do your columns have
when processed is null anyway?

Hi Shelly, It is just the old trick. You can get the time at the beginning of the page and at the end of the page and just calculate the difference in between two.

RE: [PHP-DB] [PHP] PHP and MYSQL Security`
The actual content of the .php files won't be seen from the net since it is
server side scripting language.. But if you are still concerned you can put
database connection info into another file (preferably .php file) and place
it somewhere outside your web directory and access it thru require() or
include() functions inside your actual web page.
But if your concern is for local users' access to those file , just set
your file/directory permissions accordingly.

Hi kevin,
Seems like in your while loop, you are not populating your list array
correctly with all the emails you have.
Try to have a count value and populate the array list accordingly such as:
$count = 0;
while ($row = mysql_fetch_row($result))
{
$real_name = $row[1];
$email = $row[12];
$list[$count] = $email;
$count = $count + 1;

Subject: [PHP-DB] arrays and email
I'm working on an application that will allow someone to view all attendees
for a specific webinar that my company is hosting. I want to allow the user
to send one group email to all participants scheduled for that particular
webinar.
After I connect to my database my code looks like this:
\n";
echo "\n";
echo "\n";
echo "To:\n";
echo "\n";
foreach ($list as $value)
{
print "$value, ";
$to = $value;
}

echo "\n";
echo "\n";
echo "\n";
echo "\n";
?>
The $to, $subject, & $message variables then get sent to a page that
actually mails the message. The problem I'm having is that it's only being
sent to the last person in the array. I understand why this is happening
but don't know enough about arrays to find a solution. As my code shows I
ambitiously tried setting $to to the entire array but that doesn't work.
If anyone would be kind enough to help me out I'd greatly appreciate it.
Thank you.

RE: [PHP-DB] MySQL Connection Class
Jas,
I can't know whether or not that's right for you. It all depends on what you
need to do.. If you only have one database connection with one userid/pass
combination, then yes it might be the solution you are looking for. But if
you want to be able to reuse your code for different types of databases,
userids, then you can write a class with different functions and variables
to do so.
For example you can something like
class myDBConnClass {
var $user;
var $pass;
var $host;
var $database;
function setUser($username)
{
$this -> user = $username;
}
function setPass($password)
{
$this -> pass = $password;
}
function setHost($hostname)
{
$this -> host = $hostname)
}
function setDatabasename($databasename)
{
$this -> database= $databasename;
}
function mySQLconn($username, $password, $hostname, $databasename)
{
mysql_pconnect("$username", "$password", "$hostname");
mysql_select_db($databasename);
}
function mySQL()
{
mysql_pconnect("($this -> host).", ".($this -> user).",
".($this -> pass)." );
mysql_select_db($this -> database);
}
.
.
.
.
} // end of class myDBConnClass
Say you have saved this into myDBConnClass.php .. Then in your php pages
you would first require this file with require("myDBConnClass.php");
statement, and then you would create another class extending this or just an
instance of this class (depending upon what you actually have in your class
and pages.
Keep in mind that this is a very primitive and kind of useless class.. You
can always have more properties of the class and more functions..
If you prefer you can hardcode the login, databasename info to the class
and call the connection fucntions without arguments, or you can set the
variables of the class and use it so, you can also have more functions to
connect to the different databases (PostGreSQL, Oracle, etc.) .
Does this help???

I am looking particularly at HTTP_REFERER, paths through the site, and most viewed products. Questions 1. Am I reinventing the wheel? and would it be better to buy a package (Spending money brings me out in a nasty rash, and leaves me feeling a little unsteady on my feet, but is sometimes the best option), or use a free one. The intended audience is non technical managerial type bods so nothing too difficult to understand :) 2. If I do use an existing package, are there any that are good with dynamic sites and the parameters passed to scripts, rather than just logging static pages? 3. Writing a database driven stats package on a medium traffic site (3-500 visits a day, Average 8-12 pages per visit=6000 inserts a day, peaking at 2-3 per second ) will mean lots of inserts, and a few reads when the analysis is run. Running MySql on a 1.5GHz 512MB machine, is it better to leave the table unindexed and put up with slow analysis, or will the machine cope with indexes? The data could be aggregated periodically, but if possible left intact for up to a year to follow trends. 4. Is a (MySql?) database driven system a good answer, or just the wrong way to go??

addslashes(), stripslashes(), strip_tags(), nl2br() , htmlspecialchars() etc. etc ... check PHP online documentation for more info on them..

RE: [PHP-DB] mysql and auto_increment
Yes you sure can,.. When you insert a row just use one of the older values that no longer exists on the table.. Alternatively, you can insert a blank value, mysql will automatically set it to the next value after the highest one in the table and then you can update it to one of the older values.

RE: [PHP-DB] Help on PHP vs JAVA
That's a pretty naive question to ask. For what specific task do you want to compare them ? Besides if you can't write a comparison article on PHP vs. JAVa , how can you set the outcome in PHP's favor? I would advise you to sit down and try to do the task both in Java and PHP , and compare both . They both are free, they both are cross-platform, but you can compare them in terms of their capabilities to do things, performance, speed, easiness to write and maintain the code , etc. And the result would differ according to the project you are working on...

RE: [PHP-DB] Parse Error
Not enough information given to figure out what's going on, but looking at
your query i see:
"WHERE $cars =
"$car_type\",\"$car_model\",\"$car_year\",\"$car_price\",\"$car_vin\",\"$dlr
_num\"");
do you keep 6 different values separated by commas in the field referenced
by $cars??? If this is correct what values you are passing for all those
variables? Is the $cars variable set to a valid column name in the "test"
table?? What is the data type for the column that $cars references?

First of all you don't have the variable $cars assigned..

RE: [PHP-DB] Parse Error
Ok then it sure will not work.. because you have :
"DELETE FROM $table_name WHERE $cars
=\"$car_type\",\"$car_model\",\"$car_year\",\"$car_price\",\"$car_vin\",\"$d
lr_num\"");
1- $cars is set to the value "checkbox" which doesn't exist in your test
table
2- The end of the statement $dlr_num\""); is not right , that
parenthesis isn't supposed to be there
3- The delete statement is wrong...You are storing all that info in the
separate fields but you are giving all combined as a condition in only one
field ($cars).
3- Rewrite your delete statement to delete the rows identified by the id
column as "DELETE FROM $table WHERE id ='id'"; Of course in the page where
you list the cars to be deleted associate each checkbox with the car's id.
Hope this helps..

Subject: [PHP-DB] IFNULL used in a UPDATE
Hello, I am new to SQL so I hope this is not a lame question.
I want to UPDATE two fields ('box1' & 'box2') in table 'users'.
One field I want to always set the current time.
The other field I want to put the current time ONLY if it has the value
NULL.
Here is my attempt:
UPDATE users SET IFNULL(box1 = NOW()), box2 = NOW() WHERE eMail =

Any help would be greatly appreciated.

RE: [PHP-DB] Random Selecting from mySQL
Hi! Do you have a primary key field in the table? If yes, you can after displaying the first 10 records you can put the primary key values of those records in an array and have "primary_key_fiels NOT IN (array_values_seperated_by_commas)" in your quesry.. So when you display your first page with 10 records, then you won't have any restricting values because the array will be empty. When you display it second time then you will have the first 10 records excluded and your array will be populated 20 values so that when you display the third page thos 20 will be excluded and vice versa.. Did I confuse you enough?:) I hope this helps..

RE: [PHP-DB] DB Class pointer as var in another class
Hi Gary,
I didn't understand what you were actually trying to do here.. You stated
that "Our goal here is to minimize the number of database connections per
function call." but seems like you are connecting to the database in the
constructor? So each instance will automatically connect to the DB??
Why don't you write a DB connection class and inherit it for every other
class you need to write so that all of its functions will be available in
the derived class as well and so that you won't have to call the class
inside another class?

Subject: [PHP-DB] DB Class pointer as var in another class
We've been considering the following implementation of a class pointer
within another class. Our goal here is to minimize the number of database
connections per function call. It seems to work just fine, but I wanted to
post this up for comments. PHP 4.1.1 doesn't seem to have a problem with
it. We have a couple classes working this way in some of our beta code.
I've never seen anyone do this before so I just wanted to make sure we
weren't wandering into uncharted waters.
class my_class
{
var $test;
var $db_class;
function my_class($test)
{
$this->test = $test;
$this->db_class = new database_class(DB_NAME);
}
function get_db_info()
{
... use db here via $this->db_class ...
}
}

RE: [PHP-DB] Is there a better way to do this?
Hi,
Why don't you add another column to your "items" table for the item
name..Then you can just fetch each row to an array and call it by
$row["item_name"] ?
For better explanation:
Say you added a column to hold item names in your items table called
item_name ...
I have no idea how you query items table based on which customers has what
items because you stated that there was only coumn in items table, but if
you were to query everything in the items table, you'd do:
$query="select * from items";
$result=mysql_query($query);
$num_results = mysql_num_rows($result);
for($i=0; $i < $num_results; $i++)
{
$row = mysql_fetch_array($result);
// then you can reach item number and item name just by calling them
$itemnumber= $row["number"]; //assuming that the column that holds the
item numbers has the name number
$itemname= $row["item_name"]; // assuming that the column you'll add for
item names will have the name iten_name
}
Does this make sense to you? Or are you looking for something else? Let us
know...
Thanks,
Gurhan

Subject: [PHP-DB] Is there a better way to do this?
I operate a small game site for kids. On this site, the players can, among
other things, buy virtual items. I have each item stored in a table called
"items" in a mysql database. The type is one column in that table, but it
is a number, not a name. When I want to display items with the item name, I
have to send a query to the item_types table to get the type name. The
problem is, if a user has 50 items, it takes 50 queries to get the types.
Is there any better way?

RE: [PHP-DB] Filesystem functions and mysql
Hello Tom, First of all, since you are keeping the filepaths and filenames you don't need to worry about any of the filesystem functions.. You just need to replace variables in the right places in your output HTML code. As for how to implement what you need, I will give you a different tip. Write a php script to randomly select and display images. You can either use PHP's random functions to accomplish this or if you will store filepath, filename info in a MySQL database then you can accomplish this by issuing: "SELECT ... FROM ... ORDER BY RAND() LIMIT 1;" Then you can just stick in meta refresh tag in your html output and set the value to 15 or 30 seconds.. So now you have a php page that randomly selects an image and displays it and refreshes for every 30 or 15 seconds.. Then in your main HTML page where you want this to be displayed , use tags to stick that PHP page in And you have it on whereever you want to have:) Hope this helps.. PS. You may wanna stick all filenames into an array and use shuffle() function as an alternative it thats easy for you..

Hi Andy,
That statement won't work because you have to provide the possible values
for the enum colummn. Say you can only have Y or N or that field, that you
need to type:
ALTER TABLE `test` CHANGE `field` `field` ENUM('Y','N');
By the way, if you have 250 different possible entries , I would say not to
go with ENUM, but then again it is all depend on you, and your company's

RE: [PHP-DB] Any way to do this with a minimum of queries?
Ok, if I understood correctly you have two tables one just logs IP addresses and usernames and another having user information, correct? If thats the case, just alter your users table to add an IP column (and user name column as well if needed) and use INSERT INTO ... SELECT ... syntax to populate the IP column in users tables with the values in IP table.. See: http://www.mysql.com/doc/I/N/INSERT_SELECT.html for this. And in your PHP script just have both of your insert statements to insert to the users table consistently. However this may ended up making your users table have a lot of NULL values if hte number of records in both tables don't match.

The tables gets fragmented as deletions, updates take place on a table. If
the DB operations get slower on a table, there is a good possibility that
the table has been fragmented.. If you are using MySQL , you can use CHECK
TABLE or myisamchk periodically to check your tables.
See: http://www.mysql.com/doc/m/y/myisamchk_syntax.html
and
http://www.mysql.com/doc/C/H/CHECK_TABLE.html
for more info..

Hi Barry,
First of all,
$query_id = mysql_query("INSERT INTO...); is wrong. That line will just
assign the resultset of the whatever mysql_query() function returns to the
variable $query_id .. Get rid of $query_id and just have mysql_query(INSERt

this..
Second of all, in your INSERT INTO query you are trying to insert the value

you meant to insert $artist_name instead???

All I saw was $artist_name variable that will be passed thru the form.. Can
you do a
echo $music_artist.id to see if it has a value ..
And you still need to get rid of "$query_id = " in the line that you are

Hi all,
It's Monday, it's probably something stupid, but I have poured over this all
day and cannot find the problem.
This is a simple search engine based on one table. It is suppose to return
the results of the search word. Instead it returns ALL records in the mysql
table. If I type the letter x and there are no words in the table with an x
I still get all records returned.
Would someone be kind enough to show me what I have done wrong.
if($search)
{
$query = "SELECT iname, quantity, user, price FROM
{$config["prefix"]}_shop WHERE iname LIKE '%$searchword%' AND price > 0
ORDER BY price";
$ret = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_array($ret))
{
$user = $row['user'];
$iname = $row['iname'];
$q = $row['quantity'];
$price = $row['price'];
if($searchword = $iname)
{
echo "";
echo "$user";
echo "$iname";
echo "$q";
echo "$price";
echo "";
}
}
}else{
echo "";
echo "Search Shops";

RE: [PHP-DB] Wildcards
That query doesn't make sense... All you are looking for is to get a
resultset containing ONLY the rows where name is John. So, just write:
SELECT ID, NAME, ADDRESS FROM users WHERE NAME='John';
By the way, in SQL, the wildcard character for regular expressions is the
'%' not '*' .

G'day All,
I'm using php to query a mysql db and I need to display a word count from
one of the columns and multiply it to get a quote.
So far I have this:
$thewords = count(split (" ","$adtext"));
$thequote = round(($thewords * .78),2);
In an example with 35 words it returns 27.3 but I'd like it to say 27.30. If
the total doesn't end in a zero it displays fine.
Is there a way to force the zero to display?
Cheers and thanks

Does everyone have any experiences connecting to MySQL 4.0.2 through the
socket ? Here is the deal, I have just installed MySQL 4.0.2 as the second
mysqld server on my linux machine, and , to specify which mysql to connect
to , I am trying to connect to 4.0.2 via socket in PHP, i.e.
mysql_connect("localhost:/var/tmp/mysql.sock", "user", "pass"); .
Unfortunately, this fails, I do know that MySQL 4.0.2 is up and running thru
the socket /var/tmp/mysql.sock . I can login to it thru the command line:
[root@atsiz /root]# mysql --socket=/var/tmp/mysql.sock -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 31 to server version: 4.0.2-alpha
Type 'help;' or '\h' for help. Type '\c' to clear the buffer
mysql>
The weirdest thing is that I have done the exact same coding/procedure with
4.0.1 and it did work just fine... (Including the same socket path) . Any
ideas??
Thanks in advance

Re: [PHP-DB] Column count error?
Did you copy and paste the code?
There is no such function as mysql_numrows, it has to be mysql_num_rows.. I
don't know why you didn't get an error for it?

Re: [PHP-DB] MySQL order by in greek
Hi you have to restart your mysqld server with --default-character-set=greek option. You can either do this by explicitly giving it in the command line when restarting your mysqld, or you can add that line to your global my.cnf file. See: http://www.mysql.com/doc/en/Command-line_options.html and http://www.mysql.com/doc/en/Option_files.html Hope this helps Gurhan On Wed, 2002-09-04 at 03:29, Achilleas Maroulis wrote: > Hi, I have a MySQL problem but due to small problem of my email I can't subscribe to >a MySQL list so I wonder if someone from you can answer (actually I'm sure about >it...) > My problem is that I have a query that fetches all data from a table in alphabetical >order using the "...order by col_name asc..." command.

Re: [PHP-DB] button control
PHP is a server-side scripting language, there is no way for it to know what is going on client window, that's a job for Javascript. But if you are using them in a form you can give them name/value to use them as form variables which can be used in the form action. This is a general PHP question, not DB related, forward this kind of issues to php-general mailing list.

[PHP-DB] mysql_num_rows
Hi everyone, I have a problem with mysql connectivety which is making me nuts. If the query is "select blah, blah from table" (i.e. without where clause) mysql_num_rows returns the right number, but when i put in a query with where clause, although there are rows returned, PHP is giving: "Warning: Supplied argument is not a valid MySQL result resource" error.. Can anyone point me to any direction about this? Thanks.

RE: [PHP-DB] mysql_num_rows
I am pretty sure that the query is correct. here is the actual query: $query="select distinct(nodeid), nodename from books where bookid=$bookid"; $result=mysql_query($query); $num_results=mysql_num_rows($result); I have loaded a book into the tabel called "books". I have gave each section a nodeid and each book a bookid. SO i wanted to get number of distinct nodeid's (i.e. sections) in the book so that i could use a for loop to display all of them and an inner for loop to display each page under each section. The funny thing is that if i write the same query without "where bookid=$bookid" then the mysql_num_rows works but with where statement it doesn't. By the way the web hoster i am using has PHP Version 4.0.6 . Thanks. Gurhan -Original Message- From: Richard S.

RE: [PHP-DB] mysql_num_rows
hmm that's an idea... I stil don't get why mysql_num_rows wouldn't work with WHERE clause but i will try to do a workaround with what you said below. Although it will be a little extra coding I guess I don't have any other choice:) Thank you very much for your help:) Gurhan -Original Message- From: Richard S. Crawford [mailto:[EMAIL PROTECTED]] Sent: Sunday, January 06, 2002 3:34 PM To: Gurhan Ozen; [EMAIL PROTECTED] Subject: RE: [PHP-DB] mysql_num_rows Hm, if the result you want is the number of distinct nodeid values, why not use a query like this: "select count(distinct(nodeid)) as nodecount from books where bookid = $bookid"; Then the number of nodeid's is stored in nodecount. You might also want to look into the GROUP BY clause. That might give you a better handle on what you want to do.

RE: [PHP-DB] mysql_num_rows - update....
I think i narrowed down the problem and know what is wrong, and just
solved the problem:). The problem wasn't with mysql or php it was because of
my poor i should say object-oriented skill. I will tell why I had this
problem so that it might be a good reference for someone else who are likely
to get in the same trap:)
I wrote a class in PHP which serves as a template to all other pages. It
is called "page_layout.inc" and also have another include file (db.inc)
which takes care of db connection.
So, everypage I have has require("../../page_layout.inc"); and require
("../../db.inc"); lines.
Normally, my pages just set title of the page and the content of the page
by either giving arguments to SetTitle() and SetContent() functions or
overridding DisplayContent() function. So the code pretty much looks like
this in every page:
For those setting SetTitle and SetContent functions:
require ( "../../page_layout.inc");
require ( "../../db.inc" );
$query="select * from $tab where encoding = 0 and
articleid=$articleid";
$result=mysql_query($query);
$row = mysql_fetch_array($result);
$page = new page_layout();
$page -> SetTitle($row[title]);
$page -> SetContent($row[content]);
$page -> DisplayPage();
And For those overridding DisplayContent() function:
require ("../../page_layout.inc");
require ("../../db.inc");
class testpage extends page_layout
{
function DisplayContent()
{
.
.
.
} // End of DisplayContent() function
} //end of class testpage
$page= new testpage();
$title= "TITLE";
$page -> SetTitle($title);
$page -> DisplayPage();
Ok, the problem i was having with mysql_num_rows have occured in the
DisplayContent() function in the new class. Here are some of the things I
have tried:
$query="select distinct(nodeid), nodename from books";
$result=mysql_query($query);
$num_results = mysql_num_rows($result);
This has worked ok. It didn't have a where clause and it did work.
$query="select distinct(nodeid), nodename from books where
bookid=1002";
$result=mysql_query($query);
$num_results = mysql_num_rows($result);
This has worked fine as well. When i hard coded the bookid it works.
$query="select distinct(nodeid), nodename from books where
bookid=$bookid";
$result=mysql_query($query);
$num_results = mysql_num_rows($result);
This didn't work because I haven't paid enough attention to the
object-oriented methodology. I failed because when i pass the variable
bookid as an argument to the pagename (i.e. show_book.php?bookid=1001), it
is not passing the value inside new the class. So I had to find a way to
pass that vaue into the class so that the new overridding DisplayContent()
function could use it. There are a couple ways to do this, and I have used a
set function. I have created a variable in the new class called $booknum.
Then I wrote a function to set it called SetBooknum. It took an argument and
set the variable $booknum to the argument. then Inside the DisplayContent()
function I have used a variable called $booknumber to correspond to the
bookid column in the table. So it looked like this:
class testpage extends page_layout
{
var $booknum;
function SetBooknum($num)
{
$this -> booknum = $num;
}
function DisplayContent()
{
$booknumber= $this -> booknum;
$query="select distinct(nodeid), nodename from books where
bookid=$booknumber";
.
.
.
} //end of function DisplayContent()
} //end of class testpage
And then after creating the instance of the new class I have just used
SetBooknum() function to pass the bookid variable into the new class and use
it as the search criteria in the query.
Thanks to all who tried to help me.

[PHP-DB] any good web hosting with php and mysql support?
Hi All, I am currently looking for a reliable web host to host my personal website. I know there are millions of web hosting companies that have PHP and MYSQL support but I just can't trust any of the fully-assured and confident webhosting ads anymore. I would like to get a service from a company for which someone can vouch. I did started hosting my web site at a webhoster that promised 99.99% uptime and my site is hardly ever up and running. They don't answer my emails either. IS there anyone who have web sites hosted at webhosting service for a reasonably long time without any problems? IF yes, can you please contact me and tell me about it? This might be kind of off-topic for both lists, and i apologize to both lists, so you might want to reply to my email rather than sending it to list(s). Thank you very much.
