install_plugin_overwrite_comparison filter

Filters the compare table output for overwriting a plugin package on upload.

To use install_plugin_overwrite_comparison filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_install_plugin_overwrite_comparison_defaults which takes 3 parameters and we registered using add_filter. The first parameter install_plugin_overwrite_comparison is name of the hook, The second parameter modify_install_plugin_overwrite_comparison_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove install_plugin_overwrite_comparison filter.


    Below are the 3 parameters are required to use this hook.

  • $table : (string) The output table with 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 Example

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

Below is an example how you can use this hook.

                        function 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", "modify_install_plugin_overwrite_comparison_defaults", 10, 3 );

To remove a hook callback, use the example below.

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

Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
