Executing a Drupal rule using JavaScript: A step-by-step guide

I'm facing a challenge when trying to activate a Drupal rule using JavaScript code.

      lowerLayer[image.feature_nid].on("dragend", function() {
               var position = kineticImage.getPosition();
               var layerPosition = this.getPosition();
               var slotNid = kineticImage.slot_nid;
               positionX = position.x + layerPosition.x;
               positionY = position.y + layerPosition.y;
               //Here is where I want to trigger the Drupal rule
        });

I have indicated the line where I require the Drupal rule to be triggered. Is it possible to invoke a Drupal rule with these parameters (slotNid,positionX,positionY) similar to calling a function (someFunction(slotNid,positionX,positionY)?

If you have any solutions or suggestions, please feel free to share them. Thank you.

Answer №1

As suggested by Clive, accomplishing this task can be done through an ajax call.
You will need to set up a page callback within a menu hook in your unique module, specifying the function to be executed upon page request.

Example:
// Insert this code inside the menu hook
$items['ajax/rule2.2'] = array(
    'title' => 'Rule 2.2', 
    'page callback' => 'custom_rule_trigger', 
    'access arguments' => array('access content'), 
    'file' => 'custom_rules.inc',
);

// Then you can write PHP code that needs to run under the custom_rule_trigger function in the custom_rules.inc file.
function custom_rule_trigger(){
// Add your specific rules here.. 
}

Using Javascript, you can trigger your rule by calling the www.example.com/ajax/rule2.2 URL.

I hope this explanation proves useful.
