How to use install_plugin_overwrite_comparison filter in WordPress

Hey there! If you’re diving into WordPress development, you’re probably familiar with hooks. Today, let’s talk about the install_plugin_overwrite_comparison filter. This hook is super handy for customizing the compare table output when you’re overwriting a plugin package on upload.

First things first, to use the install_plugin_overwrite_comparison filter, you need to register it using add_filter. You can place this code in the functions.php file of your active theme or, better yet, in a custom WordPress plugin. At WePlugins, we always recommend creating a custom plugin to ensure your changes remain intact during theme updates.

Here’s a quick rundown of the parameters involved:

• $table: (string) The output table containing Name, Version, Author, RequiresWP, and RequiresPHP info.
• $current_plugin_data: (array) Array with current plugin data.
• $new_plugin_data: (array) Array with uploaded plugin data.

Live Examples

Example 1: Modifying the Compare Table

In this example, we define a function weplugins_modify_install_plugin_overwrite_comparison_defaults to modify the compare table. We then register it using add_filter.

    function weplugins_modify_install_plugin_overwrite_comparison_defaults($table, $current_plugin_data, $new_plugin_data) {
        // Update the $table variable according to your website requirements and return this variable.
        // You can modify the $table variable conditionally too if you want.
        return $table;
    }
    // add the filter
    add_filter("install_plugin_overwrite_comparison", "weplugins_modify_install_plugin_overwrite_comparison_defaults", 10, 3);
    

Example 2: Applying the Filter

Here’s how you can apply the install_plugin_overwrite_comparison filter:

    apply_filters('install_plugin_overwrite_comparison', string $table, array $current_plugin_data, array $new_plugin_data);
    

Example 3: Removing the Filter

Sometimes, you may need to remove a registered hook. You can use remove_filter to remove the install_plugin_overwrite_comparison filter.

    remove_filter("install_plugin_overwrite_comparison", "weplugins_modify_install_plugin_overwrite_comparison_defaults", 10, 3);
    

Please ensure you provide the same callback function name, priority, and number of arguments when removing the hook callback.
