Action And Trigger support in my modules

Posted by bboldi on July 7, 2008 at 7:37am

I'm trying to implement actions - trigger support in my module (not standard NODE / USER / TAXONOMY actions, but my custom ones). Can anyone point me to some documentation which describes this in details, or perhaps give me a hand with this problem. Thanks in advance.

I understand that

hook_hook_info()

is responsible for letting the engine know about available actions, and I assume that

hook_action_info()

is responsible for providing triggers, but there is no info about this hook in api doc.

sorry for my English.

I' ve found some more info, but I still need help...

Creating Actions is fairly

Posted by criznach on July 7, 2008 at 7:33pm

Creating Actions is fairly straight forward and works as documented here:
http://drupal.org/node/172152

Creating triggers is definitely possible, but not very well documented, and I'd recommend looking at the simplest of the existing trigger implementations - maybe node.module...

You may find some triggers help in this talk...

Action-Trigger creation, usage, module development - Solved :)

Posted by bboldi on July 8, 2008 at 10:39am

Here is a sample module code I wrote to demonstrate the method for defining new actions and triggers and join them together. I hope it will help the community ;)

This code will add a new tab to the trigger page named "action trigger sample", it's simple and understundable... i hope...

<?php
/**
 * @author Bednarik Boldizsar
 * @copyright 2008
 */

function atsample_init()
{
    // fire the trigger
    
    _atsample_invoke_every_page_trigger();
    _atsample_invoke_random_page_trigger();
}

function _atsample_invoke_every_page_trigger()
{
    $aids = _trigger_get_hook_aids('atsample', 'on_every_page');
    
    foreach ($aids as $aid => $action_info) {
        
        $message = 'EVERY PAGE Hello World!';
        actions_do($aid,$message);
    }

}

function _atsample_invoke_random_page_trigger()
{
    function make_seed()
    {
      list($usec, $sec) = explode(' ', microtime());
      return (float) $sec + ((float) $usec * 100000);
    }

    srand(make_seed());
    $randval = rand();
    
    if(($randval % 3) == 0)
    {    
         $aids = _trigger_get_hook_aids('atsample', 'on_random_page');
          
          foreach ($aids as $aid => $action_info) {
            $message = 'RANDOM Hello World!';
              actions_do($aid,$message);
        }
    }
}

function atsample_hook_info() {
  return array(
    'atsample' => array(
      'atsample' => array(
        'on_every_page' => array(
          'runs when' => t('On every page'),
        ),
        'on_random_page' => array(
          'runs when' => t('On random pages'),
        ),
      ),
    ),
  );
}

/**
 * Implementation of hook_action_info().
 */
function atsample_action_info() {
  return array(
    'atsample_show_message' => array(
      'description' => t('Show a Hello World message!'),
      'type' => 'atsample',
      'configurable' => false,
      'hooks' => array(
        'atsample' => array('on_every_page', 'on_random_page'),
      )
    ),
  );
}

/**
 * The action callback function
 */ 

function atsample_show_message(&$object,$context)
{
    drupal_set_message($object);
}
?>

HI, where should this code be placed?

In a custom module, or in actions.inc or somewhere else entirely?

Thanks

Wow, just reread this - you'd think I would've copped that from where you said "Here is a sample module code I wrote"! Cheers man, sorry for the silly question!
