Persistent Dismissible

A class for encapsulating the logic required to maintain a relationship between the database, a dismissible UI element (with an optional lifespan), and a user's desire to dismiss that UI element.

Think of this like a WordPress Transient, but without in-memory cache support, and that uses the wp_usermeta database table instead of wp_options.

We invented this utility to centralize and minimize the code required to execute multiple different calls and checks to the User Meta and User Options APIs inside of WordPress Core.

We use this as the engine to power if and when we should show persistent admin-area notices to logged-in WordPress users. Dismissals can be set to expire after some number of seconds. They are global by default in a multisite environment, but can be per-site. Custom values can be saved if necessary.

Setup

Include in your plugin or theme however you feel is best.

Use with a PHP use statement:

use Sandhills\Utils\Persistent_Dismissible as PD;

Set

PD::set( [
	'id' => 'sh_dismissible_promotion_xyz'
] );

Get

$is_dismissed = PD::get( [
	'id' => 'sh_dismissible_promotion_xyz'
] );

Delete

PD::delete( [
	'id' => 'sh_dismissible_promotion_xyz'
] );
