If you need to add all countries to a specific geo zone in OpenCart, then you will need to spend several hours of work time for this, because there are about 250 countries and territories in the list, each of which must be selected and added manually. This task is not very difficult, but with monotonous operations for a long time, you may miss some countries. Automating this process will allow you to reduce your work time and eliminate the possibility of errors.
We have developed a modification that adds the "Add all countries" button to the geozone creation or editing form. Thus, with one click, all countries will be added to the list of geozones in OpenCart.
Extension installation instructions:
Upload the module in the admin panel in the "Extensions" : "Install".
Go to the "Modifications" section and update the cache.
Go to the "Dashboard" section and update the template cache (only for OpenCart 3).
The OpenCart team has officially presented release 3.0.5.0, which contains a significant package of fixes, code cleanup, and compatibility improvements with modern PHP versions.
On November 20, 2025, a new major release of PHP was published - version 8.5. PHP 8.5 introduces useful improvements, but requires a careful approach when integrating into existing OpenCart projects.
The simplest way to solve this problem is to create an OCMOD modification that automatically adds module_id to the OpenCart module settings.
