   I am attempting to write a filter that extracts part of the the_content and uses it in another function to return a formated string (a link).

   In short, every time a user puts {{id:999}} in the post body (where 999 is any integer), I want it to return a formated link created by another function ( tnk_contact_link() ).

   Here is my non-working example:

   tnk_contact_filter($text);
   {
   
       $pattern = '\{id\:[0-9]+\}';
       $stat = preg_match_all($patern, $text, $hit);
   
       foreach($hit as $contact)
       {
           $id = str_replace(array('{{id:', '}}'), '', $contact);
           $replacement = tnk_contact_link($id);
           $filtered = str_replace($contact, $replacement, $filtered);
       }
       return $filtered;
   
   }
   
   add_filter('the_content', 'tnk_contact_link');

   Right now it causes the post to disappear because it is not doing the find/replace inline.

   All I really need is a plugin that does something similar to look at, and I think I can figure it out from there.

   Here is the version that eventually took shape. It replaces against a lookup for {c:999}. I'm posting it here for anyone who might come across it.

   function tnk_contact_filter($text)
   {
       preg_match_all('/\{c:([0-9]+)\}/', $text, $brother);
   
       foreach ($brother[1] as $id)
       {
           $find[] = "/\{c:($id)\}/";
           $replace[] = tnk_contact_link($id);
       }
   
       if (!empty($id))
       {
           $text = preg_replace($find, $replace, $text);
       }
   
       return $text;
   }
