The "Extending Smarty" page at http://wiki.civicrm.org/confluence/display/CRMDOC/Extending+Smarty gives instructions for writing custom php functions and calling them from Smarty templates used in Pages, by using the pageRun hook to add a plugin directory to your template. But this doesn't work for Forms.

For example, a custom function works from the main Case dashboard, but not from the search view when filtering Cases by status.

How do I have the plugin directory included in Forms, not just Pages?

Use the config hook instead of pageRun. I originally had this hook in place, as per the example at "Extending Smarty":

function civicrm_pageRun(&$page) {
  $template = $page->getTemplate(); // retrieve Smarty template object
  array_push($template->plugins_dir, '/path/to/civi_custom/plugins');
}

I replaced that with:

function civicrm_config( &$config ) {
  $template =& CRM_Core_Smarty::singleton( );
  array_push($template->plugins_dir, '/path/to/civi_custom/plugins');
}

and now I can use my custom Smarty functions from both Pages and Forms.

  • Yeah, hook_civicrm_config makes more sense. I'll do a quick update to the wiki. If you come across another problem like this, consider updating the wiki. ;) Also, a relative path within the module/extension dir might be better -- consider using __DIR__. – Tim Otten Jan 7 '16 at 1:09
