in_plugin_update_message-file action

The dynamic portion of the hook name, $file, refers to the path of the plugin’s primary file relative to the plugins directory.

To use in_plugin_update_message-file action, first you have to register it using add_action. 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 execute_on_in_plugin_update_message-file_event which takes 2 parameters and we registered using add_action. The first parameter in_plugin_update_message-file is name of the hook, The second parameter execute_on_in_plugin_update_message-file_event 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_action to remove in_plugin_update_message-file action.


    Below are the 2 parameters are required to use this hook.

  • $plugin_data : (array) An array of plugin metadata. See get_plugin_data() and the ‘plugin_row_meta’ filter for the list of possible values.
  • $response : (object) An object of metadata about the available plugin update.
    (string) Plugin ID, e.g.[plugin-name].
    (string) Plugin slug.
    (string) Plugin basename.
    (string) New plugin version.
    (string) Plugin URL.
    (string) Plugin update package URL.
    (string[]) An array of plugin icon URLs.
    (string[]) An array of plugin banner URLs.
    (string[]) An array of plugin RTL banner URLs.
    (string) The version of WordPress which the plugin requires.
    (string) The version of WordPress the plugin is tested against.
    (string) The version of PHP which the plugin requires.

Live Example

function wpdocs_plugin_update_message( $plugin_data, $new_data ) {
    if ( isset( $plugin_data['update'] ) && $plugin_data['update'] && isset( $new_data->upgrade_notice ) ) {
            '<div class="update-message"><p><strong>%s</strong>: %s</p></div>',
            $new_data -> new_version,
            wpautop( $new_data -> upgrade_notice )
add_action( 'in_plugin_update_message-my-plugin-name/my-plugin-name.php', 'wpdocs_plugin_update_message', 10, 2 );

Below is an example how you can use this hook.

                        function execute_on_in_plugin_update_message-file_event($plugin_data, $response){
                           //You can write code here to be executed when this action occurs in WordPress. Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
                        // add the action
                        add_action( "in_plugin_update_message-file", "execute_on_in_plugin_update_message-file_event" , 10, 2);

To remove a hook callback, use the example below.

remove_action( "in_plugin_update_message-file", "execute_on_in_plugin_update_message-file_event", 10, 2 );

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