   This is probably a very simple question for those who know the answer.
   I've got problems with my plugin: It needs two filters - comment_text and get_comment_ID - but when I try it in this form
   

   function my_filter_function($comment_text, $get_comment_ID) {
   ...
   }
   add_filter('comment_text', 'my_filter_function');
   add_filter('get_comment_ID', 'my_filter_function');

   I get this message:
   "Warning: Missing argument 2 for my_filter_function() in /var/...path.../wp-content/plugins/my_plugin.php on line 20"

   "line 20" is "function my_filter_function($comment_text, $get_comment_ID) {"
   I guess, the second variable ("argument 2") isn't delivered.

   So: How can I use several filters for one function?

   maybe you should try sth. like this:

   ...
   add_filter('comment_text', 'my_filter_function',10,2);
   ...

   After defining filter and function, you should specify priority (by default 10, and number of accepted argument (by default 1).

   accepted_args is an optional integer argument defining how many arguments your function can accept (default 1), useful because some hooks can pass more than one argument to your function.
