hide admin notices in WordPress.

hide-admin-notices.php

add_action('admin_enqueue_scripts', 'ds_admin_theme_style');
add_action('login_enqueue_scripts', 'ds_admin_theme_style');
function ds_admin_theme_style() {
	if (!current_user_can( 'manage_options' )) {
		echo '<style>.update-nag, .updated, .error, .is-dismissible { display: none; }</style>';
	}
}

hey Alex,

Thanks for the snippet, but it doesn't seem to work anymore, just letting you know.

Hello Kyzoe,
You could just block it overall in notice by adding the below to the funtion.php file:

{
echo '<style>.wp-core-ui .notice.is-dismissible { display: none; }</style>' ;
}

Works as expected thanks, here is my version. just use in functions file or small plugin.

small plugin: https://github.com/devuri/hide-wp-admin-notices

add_action('admin_enqueue_scripts', function () {
	if ( ! current_user_can( 'manage_options' ) ) {
		echo '<style>.update-nag, .updated, .error, .is-dismissible { display: none; }</style>';
	}
});
