How to hide WordPress update mesages
CSS
The low-tech way to hide something is using css:
// Low-tech hiding of update-mesages
// source: http://wpsnipp.com/index.php/functions-php/hide-update-nag-within-the-admin/
function remove_upgrade_nag() {
echo '<style type="text/css">
.update-nag {display: none}
</style>';
}
add_action('admin_head', 'remove_upgrade_nag');
This more-or-less works, but it is a lot of work to find al the places WordPress shows messages.
Add_action
A better way is using actions. The wordpress-core (core in this context is WordPress itself) update messages are triggered in wp-admin/includes/update.php, line 84 core_update_footer, and line 139 with the great name update_nag. We can use actions to disable these:
//hide core updates notification in the dashboard
function hide_wp_update_nag() {
remove_action( 'admin_notices', 'update_nag', 3 ); //update notice at the top of the screen
remove_filter( 'update_footer', 'core_update_footer' ); //update notice in the footer
}
add_action('admin_menu','hide_wp_update_nag');
As an alternative to:
add_action( 'admin_notices', 'update_nag', 3 );
You might want to use, for multi-site:
add_action( 'network_admin_notices', 'update_nag', 3 );
The dashboard notifications are a bit harder, bit this should do the job:
//hide plugin updates notification in the dashboard
function hide_plugin_update_indicator(){
global $menu,$submenu;
$menu[65][0] = 'Plugins';
$submenu['index.php'][10][0] = 'Updates';
}
add_action('admin_menu', 'hide_plugin_update_indicator');
Although the update notices are hidden, it is still possible to see that something needs to be updated on the following pages (and do the updates):
- /wp-admin/update-core.php
- /wp-admin/themes.php
- /wp-admin/plugins.php
Disabling updates
If you completely want to disable updates, use:
//http://codex.wordpress.org/Transients_API
add_filter('pre_site_transient_update_core', create_function('$a', "return null;")); // disable core update
add_filter('pre_site_transient_update_plugins', create_function('$a', "return null;")); // disable plugin update
add_filter('pre_site_transient_update_themes', create_function('$a', "return null;")); // disable theme update
This will completely disable updates for core, plugins and themes.
Plugins
You might put this code in a functionality plugin, so it works in all themes.
Some ready-made plugins:
- No update nag plugin can do (some of) this for you as well
- Disable WordPress Core Updates
