Re: [PHP-DB] CREATE TABLE LIKE, error

Quote: In MySQL 4.1, you can also use LIKE to create a table based on the definition of another table, including any column attributes and indexes the original table has: CREATE TABLE new_tbl LIKE orig_tbl; CREATE TABLE ... LIKE does not copy any DATA DIRECTORY or INDEX DIRECTORY table options that were specified for the original table.

Re: [PHP-DB] mysql + php

Now I am programming php+mysql. I put word, excel, mpeg and
any binaries into
the mySQL database using php on linux server,But I can take out these
binay
from mySQL database. I would like to see the files and save my pc from
server. So how can I take out from
these binaries?

$sql_insert = "INSERT INTO objects(b_col, file_name, file_size,
file_type,file_date) VALUES
('$UploadedFile','$UploadedFile_name','$UploadedFile_size','$UploadedFile_ty
pe',now())";
mysql_query($sql_insert);
Are you sure anything is even being put in the database here? There's no
error checking. Is the blob empty?
// But it does not work at. I can not see anything in my browser
$sql_select = "select b_col, file_name, file_size, file_type,
file_date
from objects where file_name like 'gball.gif'";
if(!($result=mysql_query($sql_select,$db))){
die;
}
$file_name = mysql_result ($result,0,"file_name");
echo $file_name;
You need to check what's actually in your database. If you don't get a
result here, then there's nothing matching "gball.gif" in your database
(even if you think there is).
As for displaying these files again (obligatory mention that storing binary
files in the database is a BAD idea, IMHO) it's a simple matter of using
header() to send an appropriate CONTENT header matching whatever kind of
file you're sending "text/plain", "image/jpg", etc and then echoing the data
from the blob.

Re: [PHP-DB] convert date in german format
From: Ruprecht Helms [EMAIL PROTECTED] how can I convert a date stored in a mysql-database for output in the german format (dd.mm.yy). I tried date (d.m.y,$row-from); but I still get the english-format stored in the database. The databasefield is type date. That's because date() wants a Unix timestamp. MySQL has it's own format. You have two options. Option 1 is to use DATE_FORMAT() in your query to retrieve the date already formated. DATE_FORMAT() works similar to the PHP date() function. Look it up in Chapter 6 of the MySQL Manual. Option 2 is to use UNIX_TIMESTAMP() in your query to retrieve the MySQL date formatted as a Unix timestamp. You can then pass this value to the PHP date() function and format it like you have above. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What's the benefit of using an absolute path? If you did need to change the include path, you'd only have to do it in one file. Or am I misunderstanding what you are saying (likely)? I don't think there's much of a benefit, really. I really don't like being dependent upon php.ini changes (although you can change the include_path with ini_set()). Generally, the way I program is to have a variable in an include file that determines the include path, anyhow. So, if the program or these include files move, I still only have to change it in one place (well, one place in each program using the absolute path, I guess). This all comes down to a matter of preference. Since all of the scripts are on the same computer and you can change php.ini, the above method (yours) is probably the easiest to use. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

while($customer = mysql_fetch_object($res)) {
echo stripslashes($res-customer).'br'.\n;

why the backticks and not quotes ?
Because quotes would make it a string. Backticks are used to deliminate
column and table names.
If you said: SELECT 'column' FROM Table
You'd get a result set with the literal string column as the value. Works
the same in the WHERE, ORDER BY, GROUP BY, etc clauses, also.

Re: [PHP-DB] SELECT COUNT - result from two tables
From: Boyan Nedkov [EMAIL PROTECTED] Putting more than one table in the FROM clause means tables are joined, then at least following problems could arise: - using WHERE clause you can have empty recordset returned and then COUNT conflicts with it because there is actually no any data to be returned; There won't be a conflict, COUNT(*) will just return zero. When you use COUNT(*) there will _always_ be a row returned, either zero or the count. - joining two (or more) tables without using aliases to the equally named columns in the SELECT/WHERE/COUNT clauses will produce error message instead of expecting data; You don't need an alias and the columns don't have to be equally named, but yes, you have to join them somehow against some column.

Re: [PHP-DB] number_format problem
From: Dillon, John [EMAIL PROTECTED]
I want to show a number from a database in the format x,xxx.00 in a
textfield, then if it is changed by the user I want to post the value of
the
number to a decimal field. However, once you number_format the number it
becomes a string, and numbers like 3,379.90 give a value of 3 when posted
to
the database, which is hinted at in the notes on number_format. I suppose
I
need a string to number function - can someone tell me what this might be
called please?
If you know it's going to be in a $x,xxx.xx format, then
$new_number = preg_replace('/[^0-9.]/','',$old_number);
will remove anything that's not a number or decimal point.
BUT, since we know that we can't trust it'll come in that format, you may
also want to run
$rs = preg_match('/[0-9]+\.?([0-9]{1,2})?/',$new_number); //untested :)
which _should_ make sure you're not getting a number like xxx.xx.xxx or
xx.xx from some tricky user. If $rs is TRUE or 1, then the number is
in the correct format.

Re: [PHP-DB] Select Value with 's
From: Aleks @ USA.net [EMAIL PROTECTED]
First I build my select list:
SELECT NAME=Cid size=1
OPTION Selected VALUE=All Customers/OPTION
?
While ($Site = mysql_fetch_array($S))
{
$Sid = $Site[CID];
$SName = htmlspecialchars($Site[Customer]);
echo(option value='$SName'$SName/options\n);
Easy fix: echo(option value=\$SName\$SName/options\n);
Long version:
htmlspecialchars() does not change single quotes unless you pass ENT_QUOTES
as the second parameter. What you're ending up with is a value such as:
value='St. Mary's'
which, HTML will interpret as a value of St. Mary and an unknown s'
attribute. So,
$SName = htmlspecialchars($Site[Customer], ENT_QUOTES);
echo(option value='$SName'$SName/options\n);
will convert single quotes to HTML entities and not affect the value.
The easy fix above works because it uses double quotes around the value
and htmlspecialchars() already changes double quotes by default.

However, I *do* want to protect my site from any malicious data entry. I have tried to strip_tags this field, but many gamers put their team tags in their handle or use and characters within the name, so an input like team9Jester results in the team being taken out and only Jester being left.

Re: [PHP-DB] Load MySQL from a variable
From: Kim Kohen [EMAIL PROTECTED] I have some data from Filemaker Pro which needs to have a lot of search/replacing done before importing into MySQL. I have used ereg_replace in PHP and end up with a variable holding the correct data. (there are several hundred rows of data in the variable) Is it possible to use Load data infile with a variable or will I need to write out a temp file and then load that?

Re: [PHP-DB] Load MySQL from a variable
From: Rory McKinley [EMAIL PROTECTED]
AFAIK, LOAD DATA INFILE will only work off a file. So you would have to
create a temp file. Another option is to create a multiple value insert
query e.g.
INSERT INTO arb_table (arb_column_1...arb_column_n)
VALUES (arb_value_1..arb_value_n), (arb_value_1..arb_value_n), .
Making the above query should be as simple as:
$query = 'INSERT INTO arb_table (arb_column_1, arb_column_n) VALUES (' .
str_replace(\n,),\n(,$file_data) . ')';
where $file_data is your adjusted CSV file in a variable.
Although LOAD DATA INFILE is, i think, the fastest way to get data into
MySQL, if you first have to create a temp file, the additional nuisance
and
time factors might make the above query a valid alternative.
Agree that LOAD DATA INFILE will probably still be faster overall, even with
the file write. Try each and see, though.

I have a dynamic report builder for this application that creates the header, footer, rows, etc, all in the same format and it's just passed a query, any query. So, you never know how many columns there are unless you count the row returned and loop through it (or use mysql_num_fields()). ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] inserting date from text file
From: Aleks @ USA.net [EMAIL PROTECTED] I have a large text file that I am inserting into a mysql db and seem to have a problem with the date format. The data is currently in the mm/dd/ format. MySQL expects a MMDD or -MM-DD format (the delimiter for the string version can be any character, actually) I am using phpMyAdmin with the above command. I have over 1000 lines of data to add and changing all the dates would be a royal pain. Is the note a way to set the format in the column description to allow for the current data format to remain as is and have the db insert the date in the correct mySQL format?? There's no way to set a format. You could insert them into a VARCHAR column, then use an UPDATE query to pull the string apart and format it into MMDD and update another DATE column, though.

strip_tags() is used to remove HTML tags, eg for showing text on the

work
^.*$, that is being with and any number of single characters ending
with

Because you have ^ and $ (beginning of string and end of string), you're
saying the entire string must be between and in order for a match to
occur.
Take them out and make sure you're not being greedy, i.e. this tag and
that tag are left being reduced to this are left.
ereg_replace('[^]*','',$string);
or
preg_replace('/[^]*/','',$string);
should work.

Re: [PHP-DB] update db with variables
From: Robbie Staufer [EMAIL PROTECTED]
I'm writing an application that will display the contents of a db in the
browser, including the db-assigned id number. The user can then enter
the id number in a form and the browser will display the record
corresponding to that id number, with the data in editable text fields.
The user edits the text fields and submits to an 'update' script using
POST, and the update script puts the new values back into the database.
In the update script, I'm trying to access the field names and values
in the $_POST array, and update the db using a loop:
while ($data = each($_POST)) {
$name = $data[ 'key' ];
$value = $data[ 'value' ];
echo $name, $value;
$result =
mysql_query(UPDATE tablename SET $name = $value WHERE ID=$id) or die
(unable to update record);
}
The echo statement shows me that the script dies on the first time
through the loop.
Put quotes around your strings in your SQL:
mysql_query(UPDATE tablename SET $name = '$value' WHERE ID=$id)
Also, instead of dieing with your own error message, use mysql_error(),
which would have given you a better error to act upon...

Re: [PHP-DB] Query Filter in GUI
From: [EMAIL PROTECTED]
I have a PHP GUI in which a select box gets populated by a query of a
MySQL DB for all CD's by all artists when the page is first opened. I am
now trying to implement
the same query but with a WHERE clause that filters the returned CD's to
be displayed in the same select box according to the artist selected via a
group of checkboxes (one per artist). The problem so far is that if I try
to implement some flow control (if checbox one is selected, append where
artist='hendrix' to the select all CDs query, mysql_query() etc...), I get
an error message saying that the query string is empty. So I am looking
for some advice about how to implement the logic of having the same select
box display the results of different but related queries.
For example,
$query_1 = SELECT CD_title FROM CDs order by CD_title;
$result_1 = mysql_query($query_1) or die(Can't select CD_title from CDs
. mysql_error());
while($row=mysql_fetch_array($result_1, MYSQL_BOTH)) ..etc...
works just fine.
But if I try to use some flow control to alter which query statement is
assigned to $query_1...
if(checkbox one is selected)
{
$query_1 = SELECT CD_title FROM CDs WHERE artist_name = 'Hendrix'
order by CD_title;
}
elseif(no checkboxes are checked)
{
$query_1 = SELECT CD_title FROM CDs order by CD_title;
}
$result_1 = mysql_query($query_1) or die(Can't select CD_title from CDs
. mysql_error());
while($row=mysql_fetch_array($result_1, MYSQL_BOTH)) ..etc...
produces the error message stated above ... that the query string is
empty. I've also tried to duplicate the mysql_query($query_1) or
die()... within each section of the IF group, but then the select box
does not get populated at all.
In order for you to get that error, neither of your two conditions are TRUE.
Since you have pseudo-code, it's hard to tell where the problem is,
though.Something in (checkbox one is selected) and (no checkboxes are
checked) is not right.
Here's an easy way to do this, though, so pay attention. :)
Create your checkboxes like this:
input type=checkbox name=artist[] value=Hendrix
input type=checkbox name=artist[] value=Violent Femmes
etc...
Notice how they are all named the same and have different value.
Now, when processing this form, you'll have a variable $_GET['artist']
that's an array. If a checkbox was checked, then the array will have some
elements, otherwise it'll be empty and not set... so use something like
this:
if(isset($_GET['artist']) is_array($_GET['artist'])
!empty($_GET['artist']))
{
$artist_list = ' . implode(',',$_GET['artist']) . ';
$query = SELECT CD_title FROM CDs WHERE artist_name IN ($artist_list)
order by CD_title;
}
else
{
$query = SELECT CD_title FROM CDs order by CD_title;
}
Then run your query and retrieve the results like you are doing now. What
this will to is take multiple checkboxes selected by the user (or just one
if you want) and make it into a comma separated list to send to the query.
So if two checkboxes are selected, you end up with a query such as:
WHERE artist_name IN ('Hendrix','Violent Femmes')
Hope that helps.

If you save it as cron.php, you can use a command such as the following in your crontab: wget -q -O - www.domain.com/cron.php /dev/null I'm assuming you know the specifics of cron or can google for it. :) ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Need to Run a PHP script using CRON or ?
From: Jonathan Villa [EMAIL PROTECTED] wget -q -O - www.domain.com/cron.php /dev/null Interesting... how does this fair concerning security? So I'll have to have this file located in my document root, is this a good thing? My current directory structure consists of several files located outside the doc root. I guess I could always include it onto a page Well, I guess it would depend upon what your cron.php does. You must be aware that anyone can just type in the URL and run the script at any time, not just when the cron process runs it. For example, my cron.php script creates a mysql backup file and erases any backup files older than 30 days. When it runs, it first checks if the backup for today was already made or not. If it's already there, it does nothing. So, you can call this script all you want and it's not going to mess up anything. Again, it depends on what your script is doing, though. Yes, it's safer to keep it outside of the webroot and call it via the command line. This way you know it's only being called by cron and only when you want it. It just depends on whether you can do that on your system or not. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Both domains are setup on the same box.. the secure SSL area is secure.mydomain.com The session id is maintained in a cookie (by default), so when you switch from non-secure to secure you are probably losing the cookie because of the difference in domains.

Re: [PHP-DB] Populating an array from mysql db
From: mike karthauser [EMAIL PROTECTED]
I have a course booking system that allows the client to add courses and
then specify how long they run for. The admin system I have built allows
the
client to add up to 30 dates for each instance of the course and these are
adding to a database row in the form date1, date2, date3, daten etc.
What I am trying to achieve now is to extract this data into an array so I
can count how many dates have been added and to display the dates.
If the course runs for eg. 2 days - values of date1 and date2 would be
populated as date1=2003-09-01, date2=2003-09-02 - all other dates would be
default to -00-00 and I wish to ignore these.
I'm trying to work out how to set up a loop to extract positive dates from
my db so I end up with
$bookdate[0] = '2003-09-01';
$bookdate[1] = '2003-09-02'; etc
Can anyone provide me with some help in this extraction?
With just a short comment on what a horrible, horrible database schema this
is, you should be able to use
if($date_from_db != '-00-00')
{ $bookdate[] = $date_from_db; }

Re: [PHP-DB] SESSION SID Question
From: [EMAIL PROTECTED] Can someone explain to me the mechanism by which SID acquires a value? For example, $FOO = SID; echo $FOO; produces something like PHPSESSID=ade4055eef947f1a00cdb280470e859b when IE is first opened and the page is loaded, whereas reloading of the page produces an empty string when $FOO is echo'd. Seems to have something to do with creating a browser instance. SID is used to pass the session ID around in URLs. It gives you the text formatted so that you can just stick it into a URL. Normally cookies are used to hold the session id and pass it from page to page. If for some reason PHP cannot set the session cookie (or it's not present), then PHP creates SID. This means you can include SID in all of your URLs and when the cookie is there, it'll be empty and nothing will appear in your URL (rightly so), but if the cookie is not there, SID will place the session ID in your URL so that your sessions persist. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Database Design Issue
From: Jason Lange [EMAIL PROTECTED] Here's my question. I'm creating a website for a weekly radio show. One of the items I would like to store in the database is the list of songs played in each show (there's normally between 20-25 songs per show), and the songs will be displayed by show. Should I put all of the songs in a single table with a field denoting what show they're from, or should I create a separate table for each weeks show and just request that entire table? I'm looking at this from both a long-term performance and *maintenance* issue. The first question is if songs can span multiple shows? If so, you need 3 tables. One to hold the songs, each song getting a unique id. One table to hold the shows, each show getting a unique id, and finally a third table that relates the two. You'd list the song_id and the show_id that it's used in. Add in a row for each song used in each show. If a song is not shared across shows, then you could go with two tables. A show table where each show gets a unique id and a song table with a column that has a show_id in it relating it to what show it's used in. You'd be better off with the first method, though, because sooner or later down the line there's going to be a song shared, I imagine. :) ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Maximum execution time of 30 seconds exceeded
I'd agree with what someone else said about keeping a separate table full of
possible pin numbers.
Fill it with all of the pin numbers to begin with, add in a building or
department row so you know what sequences go with what building, etc.
Then, to get a pin number for someone, you can just:
SELECT pin FROM Table WHERE ... ORDER BY RAND() LIMIT 1
Where the ... determines the correct building, department, whatever.
If you end up using that pin, delete it from the table. When the student
leaves, insert it back into the table.

Subject: Re: [PHP-DB] Maximum execution time of 30 seconds exceeded
I do have an auto_increment for the record id. But that is just a way for
me
to uniquely id the record. Student numbers, barcodes, etc can change.
The reason I am using the do/while loop is: Every student is getting a
4digit pin for library, cafeteria and network access. It has to be unique
and we have been assigning a different range of numbers per building/grade.
There are various procedural reasons for this. I have verified that I am
identifying the new student correctly and going into the do/while loop with
a
variable that holds the correct starting number for the appropriate pin
range. It's then just a matter of trying consecutive numbers till I find an
available pin. The pin may be available because a student left the school
or
because it's next available at the end of the line.
Anyway, I was not aware I could pick and choose my ranges in an
AUTO_INCREMENT
field.
I appreciate any thoughts you may have. Thanks.

I basically pieced this code together from several examples I found so
forgive forgive the fact I don't know a whole lot about the code even

You could try something like this:
while($z % 3 !== 0)

$z++;

}
That way $z is only incremented when there are left over cells to be filled.
You may have to play around with it for a bit.

Re: [PHP-DB] displaying result across 3 cells - where did I go wrong?
From: Aaron Wolski [EMAIL PROTECTED] while($z++ %3 !==0) [snip] echo (++$z %3 == 0) ? '/tr' : ''; The first time through your code, $z is zero. Since the thread titles don't match, your going to get to your while loop above. $z is zero, so your while loop isn't executed, but $z is incremented to one. Then, later in your code you increment $z to two and check for the modulus 3. So basically, every time you switch thread titles, $z is incremented one more than it should be and you miss out on one cell in the following row. ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Limit
From: Marie Osypian [EMAIL PROTECTED] I don't want to use the limit on this query anymore. What I want is to display all that are dated within the last 3 months. What would be the easy way to do that? SELECT federal_development_id, UNIX_TIMESTAMP(date) AS date, topic, body FROM federal_developments WHERE pro_solutions = 'Y' AND date CURDATE() - INTERVAL 3 MONTH ORDER BY date DESC ; ---John Holmes... -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
