List of variables

[littleprince]

I'm developing a custom module and don't often develop from scratch in PHP and joomla.

Is there a list of predefined user variables? content variables?

For example:
Is there a variable or a function to get the category ID of a content page?
I know I can get the ID from the URL, and select it from the database.

But I was thinkg there must be something like $my->gid because it must be used a lot.

What a great, straightforward question!  I'm looking for the same answer, but obviously either there isn't or we're not using the right 'jargon'.

What I often do is put this code at the bottom of the template:

Code: Select all

<?php echo '<pre>' . print_r($GLOBALS, true) . '</pre>' ?>

It will display all global variables so you can look for one that works.  Obviously, you don't want this to appear to everyone  - you can put it in a module that's only accessible to you ("special" access).

You can also try here:

For information about the API.

Global objects are $my (user), $database (database - duh), $mainframe - the application, there are a few more I think, but I don't recall offhand.
