Extension Description

This is a small but powerful utility extension designed to solve one very specific and recurring problem in OpenCart 3: the PHP deprecation warning preg_replace(): Passing null to parameter that frequently appears in the storage/modification/system/engine/action.php file.

e.g, action.php line 65/67/68 errors

This error is almost always caused by another extension or theme that incorrectly modifies the action.php core file. Because the error exists in the modified file within the storage/modification cache directory, any manual fix you apply is wiped out every time you click the "Refresh" button in the admin Extensions -> Modifications area.

Key Benefits & Features

The Permanent PHP Fixer solves this problem by acting as a "patch". It runs every time you refresh your modifications cache, automatically finding the buggy line of code created by the other extension and replacing it with the corrected, safe version.
This is a "set and forget" extension. Once installed, it works silently in the background to keep your system error-free. There are no settings to configure.

Usage Instructions

There is no usage required. The extension has no user interface or settings. Once it is installed and the modification cache has been refreshed, it works automatically.

Installation Instructions

Log in to your OpenCart Admin panel.
Navigate to Extensions -> Installer.
Click the blue Upload button.
Select the permanent_php_fixer.ocmod.zip file from your computer.

You should see "Permanent PHP Fix for action.php" in the list.
Click the blue Refresh button at the top-right of the page. This is a critical step that applies the fix for the first time.
After the refresh is complete, the preg_replace() error will be gone.
