WP Flash Notices

Admin notices that survive a page reload.

Flash-style admin notices that display after a redirect

Simple, expressive API for success/error/warning notices
No dependencies beyond WordPress core

What it does

WordPress admin notices normally vanish on redirect. WP Flash Notices stores a notice as a transient and shows it once on the next page load — the flash-message pattern, done the WordPress way.

Install with Composer:

composer require foxelabs/wp-flash-notices
