Update

In the new version of the Attributico module, we have completely abandoned the use of the outdated modification mechanism (OCMOD) in favor of a modern architecture based on built-in OpenCart Events and dynamic DOM tree manipulation via JavaScript.

This approach:

• Increases the stability of the module.
• Eliminates potential conflicts with other modules at the install.xml modification level.
• Simplifies the installation and update process.

Below is a step-by-step guide for migrating from previous versions to the new one.

Step 1. Removing the Old Modification (OCMOD)

Since the new version works through the Events interface, we need to remove the old interventions in the store code.

1. Log into the admin panel of your OpenCart store.
2. Navigate to Extensions -> Modifications.
3. Find the modification named Attributico (or attributico_3) in the list.
4. Disable it (disable button) or completely delete it (trash can button).
5. Important: Click the Refresh button (blue button with arrows in the upper right corner) to clear the modification cache.

Step 2. Uploading New Files

1. Extract the archive containing the new version of the module on your computer.
2. Upload the files from the upload folder (or via the built-in extension installer) to your store's server, agreeing to replace existing files. Note: When using the built-in installer in OpenCart 3, simply upload the .ocmod.zip archive as usual.

Step 3. Activating the Events System

For the new version of the module to properly register system events for product form integration, you need to:

1. Navigate to Extensions -> Extensions.
2. Select the Modules type from the dropdown list.
3. Find the Attributico module and click the Uninstall button (red button with a minus sign). This will remove old database settings.
4. Click the Install button (green button with a plus sign). During installation, the module controller will write the necessary Event hooks into the OpenCart database.
5. Click the Edit button (pencil icon).
6. Configure the necessary module settings and click the Save button (blue floppy disk in the upper right corner).

Step 4. Checking Functionality

1. Clear your browser cache (using the Ctrl + F5 shortcut on the product edit page).
2. Clear the template cache (in the OpenCart dashboard, click the "gear" icon in the upper right -> refresh theme cache).
3. Go to any product form in the admin panel and open the Attributes tab.
4. Ensure that all Attributico module controls (buttons, search, synchronization) are displayed correctly.

🎉 Done! Your module has been successfully updated to the new version without OCMOD.

Additional: Disabling Product Form Modification

If you use third-party solutions (e.g., the Attributipro module) to manage attributes inside the product form and do not want Attributico to intervene with the appearance of the standard OpenCart product form, you can easily disable these changes.

Since the module now runs on Events, you simply need to disable two specific events:

1. Navigate to Extensions -> Events.
2. Find the event with the code attributico_add_script in the list. Click the Edit button, change the status to Disabled, and then save. (This event is responsible for injecting the module's JavaScript file into the product page).
3. Find the event with the code attributico_product_form_before in the list. Also change its status to Disabled and save. (This event is responsible for injecting additional fields, such as Group and Sort Order, into the product form data).

After disabling these two events, Attributico will stop outputting its scripts and controls in the "Attributes" tab of the product form, however, all other functions and mass editing via the module's own panel will continue to operate normally.
