hello... just wondering if anyone here is familiar with the phpbb forum software.
i'm trying to insert some PHP into each post.

So far i have made a custom BBcode, which appears on the post form, which can be filled with a word.

I've then got some PHP which is supposed to read the value contained in the BBcode and print out some HTML depending on what it is (taken from a database).
The only problem is... i don't know where to place this PHP to make it work.

I've found the file which seems to parse the BBcode (functions_posting.php), but i haven't got a clue where to look.

i need something along the lines of this

if(custom_BBcode = 'my_value') {

   // do this 

} else {

   // carry on as normal
