I have a phpBB forum and I'm trying to edit some code so that whenever someone types in \(\displaystyle Some code\) it automatically inserts <img src="mysite.com/cgi-bin-mimetex.cgi?Some code">. This will save people the trouble of typing in all of the extra stuff. It seems rather simple but I have no idea how to go about it.

Any ideas?

I would imagine the cleanest way to do this is find the script that handles the other BB codes, the add the few new tags of your own using similar syntax.

This is going to require you to do some tracing from the post display php, unless someone with experience would kindly pinpoint the file :P

With Invision Boards which I use on my site, there is a file in the /lib/ directory post_parser.php, which contains a

//-----------------------------------------
// Custom BB code
//-----------------------------------------

section. I could imagine phpBB having something similar.

That's what I was thinking, but I'm not familiar with PHP and the syntax is very meticulous.

I know the file... and I'm looking at the code right now. I'm just not sure how to recreate it. There are many parts.

Here's some of it:

Code:
function prepare_bbcode_template($bbcode_tpl)
{
	global $lang;

	$bbcode_tpl['olist_open'] = str_replace('{LIST_TYPE}', '\\1', $bbcode_tpl['olist_open']);

	$bbcode_tpl['color_open'] = str_replace('{COLOR}', '\\1', $bbcode_tpl['color_open']);

	$bbcode_tpl['size_open'] = str_replace('{SIZE}', '\\1', $bbcode_tpl['size_open']);

	$bbcode_tpl['quote_open'] = str_replace('{L_QUOTE}', $lang['Quote'], $bbcode_tpl['quote_open']);
I can see where certain parts fit in, but I couldn't write it myself.

I did some searches and it says that phpBB's code is in bbcode.php. A bit tedious to go through... that's why I didn't choose to do programming as a major >.<

However, while searching I did come across this site, which is probably the best direct help you could probably get.

Hey thanks a bunch! That's a great tutorial. I'll let you know if I get something useful written.

Hmmm... reading this through, I'm having trouble following it. I need something to the evquivalent of this.

When $text = \(\displaystyle then copy until \)
and insert <img src="mysite.com/cgi-bin/mimetex.cgi?$text">

That's not in any language of course, but the general logic of it. I tried reading that tutorial, and it starts out nicely, but kind of stops describing.

No one here knows PHP? :(
 
Further explain this and I'll give you the instructions
Do you mean when someone types \(\displaystyle text here\) it inserts <img src="mysite.com/cgi-bin/memetex.cgi?text%20here">

If so I'll give the directions ASAP

Thanks for the help, but I already got the code from someone else. Appreciate it.
