I would start by looking into the set_user_role action hook. You would be passed 3 arguments to your callback function – the User ID, the new user role, and an array of the old user roles(that seems strange to me, that you can’t pass an array of roles, but oh well). So here’s an example … Read more
The problem is not version_compare, the problem is that register_activation_hook is just a shortcut for add_action( ‘activate_’ . $file, $function ); where $file is plugin_basename( __FILE__ ); and __FILE__ is your main plugin file absolute path. So, what your code does is to call dw_deactivate_theme_options() when the action ‘activate_’ . $plugin is fired. But this … Read more
So the ‘activate_plugin’ was a typo in the question. But even so, as a friendly reminder (for all of us), activate_plugin() is an existing function in WordPress. And you should use unique prefix in your custom functions (that are defined in the global scope): function my_plugin_activate_plugin() { … } register_activation_hook( __FILE__, ‘my_plugin_activate_plugin’ ); The Problem … Read more
Use a plugin to manage roles, not a theme. Roles are not for presentation. In your plugin use register_activation_hook() and register_deactivation_hook() to add or remove new roles. Do not remove built-in roles, other plugins may rely on their existence.
The simplest way is probably renaming the plugin file or folder. But if you’re trying to handle it directly from the database, you’d have to grab the ‘active_plugins’ value from the wp_options table, unserialize it, remove your plugin from the array and reserialize it and update. You don’t necessarily have to use update_option. You could … Read more
You’ll want to find the right action to call this. After the action has been added, but before it is called. Then get the object’s instance of the callback and the same priority (10 is default). remove_action(‘woocommerce_register_form’, array ( YITH_Vendors_Premium::instance()->frontend, ‘register_form’ ), 10 );
Yes, custom post types are registered on the fly, on every request. So you can create an option, say active_custom_post_types and check for that before you register the post type. Pseudo-code: $possible_cpts = array( ‘book’, ‘portfolio’ ); $active_cpts = get_option( ‘active_custom_post_types’ ); if ( ! empty ( $active_cpts ) && is_array( $active_cpts ) ) { … Read more
You might want to add your own plugin to deactivate their plugin (silently). First open their main plugin file and see where the plugin hooks (or filters) in. Then unhook their plugin … and your’s as well. <?php /** Plugin Name: Deactivate other plugin */ add_action( ‘the_same_hook’, ‘removeOtherPlugin’, PHP_INT_MAX -1 ); function removeOtherPlugin() { remove_filter( current_filter(), … Read more
It’s a bit of a guessing game without error reports. Here are a few ways to collect info which will help you or others diagnose the cause: Turn on WP-Debug: WordPress WP DEBUG Codex page *Be careful if your site is live if you choose to use define(‘WP_DEBUG’, true); in you wp-config.php file, by default … Read more
You may need to have this line in your code require_once( ABSPATH . ‘wp-admin/includes/plugin.php’ ); The plugin.php file is not automatically included.
