Manage WordPress Admin Notices easily

WP Admin Notices

An easy and convenient way to create WordPress admin notices that can be closed persistently. Besides that it has some cool features: * Keep your notices hidden only for the user who closed it. * Display your notice on specific situations, like when some plugin gets updated or activated or on specific admin screen ids or on $_GET / $_POST requests, * Create your own special cases where/when your notice should be displayed, _(*1)

Simple Usage

add_action( 'admin_notices', function () {
    $notices_manager = \ThanksToIT\WPAN\get_notices_manager();
    $notices_manager->create_notice( array(
        'id'         => 'my-notice',
        'content'    => '<p>My Notice</p>',     
    ) );
} );

Note: By default, this library will make notices persist, meaning they will not be displayed again after user close them, unless they expire, _(*2)

Initialization

In order to make it work perfectly, you need to initialize it like this:, _(*3)

add_action( 'wp_ajax_' . 'tttwpan_dismiss_persist', array( 'ThanksToIT\WPAN\Notices_Manager', 'ajax_dismiss' ) );
add_action( 'activated_plugin', array( 'ThanksToIT\WPAN\Notices_Manager', 'set_activated_plugin' ) );
add_action( 'upgrader_process_complete', array( 'ThanksToIT\WPAN\Notices_Manager', 'set_upgrader_process' ), 10, 2 );

And it's important to make these calls before any other hook on your plugin/theme. But don't worry, this library will be loaded only when it's necessary, as it's being called on the proper hooks, _(*4)
