Hooks: Actions and Filters

A comprehensive guideline on how to use Smart Post Show filter hooks. We have added the following hooks for developers to extend functionalities. Simply add the following custom code to your current theme’s functions.php file. It’s recommended to keep the code in the functions.php file of your child theme. Because you might lose your customizations if the theme is updated. Keeping the modified codes in your parent theme’s child theme is therefore the best practice.

/**
 * Change plugin menu name.
 *
 * @param array $labels The labels.
 * @return string
 */
function sp_show_change_menu_name( $labels ) {
    unset( $labels['menu_name'] );
    $new_menu_name = array( 'menu_name' => __( 'My Plugin', 'smart-post-show' ) );
    return array_merge( $new_menu_name, $labels );
}
