Installation
1. Download the module installation files from your available resource. You should receive two zip archives: Attributico_v3.2.8.zip and License.zip. The archive structure is described in this article.
2. Extract the archive. Open the folder corresponding to your PHP version. Copy the contents of the upload.../ folder, corresponding to your OpenCart version, over the site's folder structure.
3. In the admin panel, go to Extensions ⇒ Modules. The "Attribut&co" module should appear. Install (activate) it.
4. In the admin panel, navigate to System ⇒ Users ⇒ User Groups and set permissions for viewing and editing module/attributico or extension/module/attributico (for OpenCart versions >2.2).
5. Extract the License.zip archive. Copy the contents of the folder corresponding to your PHP version over the site's folder structure.
6. In the admin panel, go to Extensions ⇒ Extension Installer and upload the files attribut&co.2.x.ocmod.xml and autocomplete.ocmod.xml (for OpenCart 2.x) or attributico.3.x.ocmod.zip (for OpenCart 3.x) from the ocmod folder.
If you are using the OCTEMPLATE theme, do not perform this step. See the installation instructions for modifications below.
7. In the admin panel, go to Extensions ⇒ Modifications and refresh the modifications.
After completing these steps, the Catalog ⇒ Attributes ⇒ Attribut&co menu item should appear.
Clear the store and browser cache. The specifics of cache clearing for OpenCart 3.x are described, for example, here.
If you have previously used an older version of the module and installed modifications directly into the system folder, you must remove them.
This means that the files attribut&co.2.x.ocmod.xml and autocomplete.ocmod.xml should not be present in your site's system folder.
In some translated versions, the term Extensions may appear as Add-ons, and Modifications may be referred to as Modifications Manager.
The word Attributes is often translated as Characteristics.
For OCTEMPLATE users!
OCTEMPLATE uses a large number of modifications, so OpenCart's ocmod system may not have enough resources to install the module's modification.
To resolve this issue, follow these steps:
Do not perform step 5 of the installation instructions.
For OpenCart versions below 3.0.x, copy the files attribut&co.2.x.ocmod.xml and autocomplete.ocmod.xml directly into the system folder of your site.
For OpenCart 3.0.x, extract the install.xml file from the attributico.3.x.ocmod.zip archive, rename it to attributico.3.ocmod.xml, and then copy it into the system folder.
Possible issues with OpenCart 1.5.x (outdated)
This module uses jQuery UI - v1.11.4+, while OpenCart 1.5.x uses jQuery UI - v1.8.
During installation, the older version will be replaced, as Attribut&co will not work otherwise.
As a result, some third-party modules may temporarily malfunction.
Update
1. After downloading the new version, extract the archive and copy the contents of the upload.../ folder corresponding to your OpenCart version over the site's folder structure.
2. For OpenCart 2.x and 3.x, you must reinstall the modifications (...ocmod.xml or ...ocmod.zip) as described above. Then, in the admin panel, go to Extensions ⇒ Modifications and refresh them.
3. When upgrading to a new version, you may need to deactivate (uninstall) the module and immediately activate it again in Extensions ⇒ Modules.
This operation will create additional database tables and new event handlers if they have been added.
4. Clear the store cache and browser cache.
5. Edit and save the module settings again.
Uninstallation
1. In the admin panel, go to Extensions ⇒ Modules, find the "Attribut&co" module, and click "Uninstall".
2. For OpenCart 2.x, delete the files attribut&co.2.x.ocmod.xml, autocomplete.ocmod.xml from the /system folder.
For OpenCart 3.x, delete the files attribut&co.2.x.ocmod.xml from the /system folder if you copied them there.
Alternatively, in the Extensions ⇒ Modifications menu, remove everything related to "Attribut&co".
Database
During module installation, the database will create a category_attribute table with fields
`category_id` INTEGER(11) NOT NULL and `attribute_id` INTEGER(11) NOT NULL.
Starting from version 2.0.1, an additional field `duty` TEXT NOT NULL is added to OpenCart's standard attribute_description table to store Duty Templates.
Additionally, extra tables will be created for compatibility with future enhanced versions of the module.
The table structure can be viewed in the diagram.
During the module removal process, no tables or fields are deleted. If this is critical for you, remove them manually, for example, using PhpMyAdmin.
