Events
Events are designed to reduce the need for modifying OpenCart core engine code through OCMOD extensions, while also enabling tracking of data changes made through native OpenCart functionality.
How the Event Handling System Works in OpenCart
OpenCart utilizes an event-driven system that allows developers to "subscribe" to specific actions within the store. When an event is triggered, the system notifies all subscribed modules, enabling them to execute custom code.
Event Handlers in Attribut&pro
| Handler | Action |
|---|---|
attributipro_add_attribute_after | Data synchronization after adding a new attribute |
attributipro_add_product_after | Data synchronization after adding a new product |
attributipro_copy_product_after | Data synchronization after duplicating a product |
attributipro_delete_attribute_after | Data synchronization after deleting an attribute |
attributipro_edit_attribute_after | Data synchronization after editing an attribute |
attributipro_edit_attribute_before | Data synchronization before editing an attribute |
attributipro_edit_product_after | Data synchronization after editing a product |
attributipro_edit_product_before | Data synchronization before editing a product |
attributipro_add_menu | Adding a link to the module in the side menu |
attributipro_add_script | Connecting the module to the product form in the admin panel |
attributipro_frontend_product | Enabling the script for modifying the product card |
attributipro_frontend_filter | Enabling a script to modify the filter |
Changes made by third-party extensions are not tracked or processed by the system.
When using Attribut&pro and Attribut&co together, only the handlers from the last installed module will remain active.
This prevents duplication since both modules share identical event handlers.
Any handler can be enabled or disabled via Extensions ⇒ Events.
