Hello,
Here is the scenario
I have a form with the folloing fields i. Title ii. Category (This
is a drop down with a list of categories which have id's - am using
wordpress ) iii. upload file field
now what i want to do is to be able to customize a link like http://www.mysite.com/addfilecat_id=5
so that when i access the link it has one of the categories in the
drop down selected..reason is i dont want users to see the
different types of categories
So i guess my question is how to configure a meu item in a drop down
to be automatically selected in a link...
Thanks

If your options are dynamically created you could check the value passed
against each option are mark the match with SELECTED;
Example Static:
Echo option value='5'; If(isset($_GET['cat_id']) $_GET['cat_id'] ==
5){ echo ' SELECETED ';} echo 5/option.PHP_EOL;
Example Dynamic
for($a=1, $a = 15; $a++)
{
Echo option value='.$a.' ; If(isset($_GET['cat_id']) $_GET['cat_id']
== $a){ echo ' SELECETED ';} echo .$a./option.PHP_EOL;
}
Just a though

Where the php script was the client and the C++ app was a server. Client only acquired sems, server only released. This cannot be done with php semaphores. Got around the first two problems: 1) Php semaphore is actually 3 sysV sems. a. Need to have the C++ program create one with 3 2) Php will reset sem 0 - the real sem whenever sem_get() is done. a. Sem 1 is a reference count - number of procs using it, and sem 2 is used to lock access to sem 1. b. Ok, so made C++ set sem 1 to 1. Actually since I know it starts 1st I just blindly do that. For some odd reason, it seems that sem 2 also needs to be set to 0... not sure why. The right way would be to wait till sem 2 is 0, then check if sem 1 0. If so, increment it and do not init sem0. Else, set sem 0 to init value, set sem 1 to 1 and set sem 2 back to 0. However, could not get past the problem that php always sets the UNDO flag. So, when the script exits, the semaphore is reset. That completely messes up the client/server approach. Another amusing note is that the C code that php uses to implement the semaphores uses the wait-for-zero feature of sysv semaphores. Kind of funny that it was seen as needed for even that little effort, but not exposed in php itself J Not to mention all of the other features... So... then. Switch to signals. But to do that correctly, I use a semaphore. In the signal handler, it releases the semaphore. When waiting for a signal in the main loop, I do an acquire. Then I find out that sem_acquire() actually returns **OK** when the underlying semop call gets an EINTR!!! Holy cow. How can a php system call loose an error?! That's just crazy.

Readers, Looking through the mail lists archives, only the following message seems to advise about the possibility to use gnuplot: http://marc.info/?l=php-generalm=96248542218029w=2 Is it possible to start gnuplot using php, to plot a graph from postgresql data. For example, a table is created in the required gnuplot data file format so the command for gnuplot would be something like: plot SELECT * FROM gnuplotdatatable; But can't see a php command to start gnuplot in the first step.

Hey, There is also an option for post_max_size = xM x being the number specified. This should be located in your php.ini file somewhere. check to make sure that this is set high enough else it could also be causing the issue.

[PHP] Parsing a simple sql string in php
Hiya, has anyone had any experience with parsing a string of sql to break it down into its component parts? At the moment I'm using several regex's to parse a string, which works, but I'm sure there's a more elegant solution. The general idea is to produce a nice looking page giving details of updated fields and values. I'm only concerned with update statements really, and the queries are very simple, operating on one table at a time, with no sub queries or selects. Thanks in advance if anyone is able to suggest anything! Thanks Ash -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks in advance if anyone is able to suggest anything! I don't have any experience doing it with SQL, but I have written several parsers in my time, and I'd strongly recommend against using regexes to do it. The usual way to approach this problem is to tokenise the input, then take each token at a time and branch where there are several options for what comes next. As you go along, build up a data structure that represents the data you need.

Apart from the possible security issues with posting content or information i don't believe that there is any others for posting large amounts of information.

[PHP] html formatting in mysql post
Hey Guys, I am using a form to post information to a MySQL table which is then echo(ing) back out to a web page. it will sort of be like facebook where you can post messages and stuff on peoples walls. The only issue is at the moment i can get the formatting to stay. When i echo the table out from mysql it all gets displayed on one line rather than seeing my new lines which i typed in the text box. I do know that this is a HTML error as it was never given the format tags when the content was posted in the table. I have seen something about NL2BR and also something about strip slashes but i am not sure how to incorporate them into my post. Could someone please advise?

Well, let's start with an easy question: have you *tried* them?
?php
// $row = /* Database row grabbed elsewhere in your code. */'';
if (is_array($row)) {
foreach ($row as $r) {
echo nl2br($row).PHP_EOL;
}
} else {
echo nl2br($row).PHP_EOL;
}
?
Error-handling and the remainder of checking is up to you.
