I am using Rules 7.x-2.2 with the latest version of Button Field (http://drupal.org/project/button_field), Session API (http://drupal.org/project/session_api) and a custom module to store some entity values in a user's session when they click a button.
To clarify, I have an entity type (Commerce product) with an HTML instance of the button field that is supposed to trigger a custom defined rules action, where I want to extract some values from the entity object that the button is associated with.
This is how my Rules action info looks currently in my custom module:
function commerce_custom_box_rules_action_info() {
return array(
'commerce_custom_box_add_to_box' => array(
'group' => t('Commerce Custom Box'),
'label' => t("Add the product to the user's box"),
'parameter' => array(
'entity' => array(
'label' => t('Product entity'),
'description' => t('The entity the clicked button is attached to.'),
'type' => 'entity',
),
),
),
);
}
And here is how my rule looks:
The problem is, in commerce_custom_box_add_to_box() (the function fired by my custom action), I have tried using dpm() on all of its arguments and none of them contain any entity properties, field values, or anything else that could even be remotely useful. All I get are empty "EntityDrupalWrapper" objects and similar. However, if I replace the action in the rule with "Execute PHP Code", there is an $entity object available there and dpm() reveals that it is in fact populated with all the usual properties.
Naturally I am trying to figure out why that object is there but isn't being received by my custom action. Perhaps I'm thinking about it in the wrong way?
A fresh pair of eyes on this would be hugely appreciated! Happy to provide more info if needed.
