How to display the 'settings updated' message

  • Hey all,

    I’m trying to get the message that tells a user that some settings have been saved to appear at the top of the screen in a plugin, but I’m having a bit of trouble.

    I have the correct code and have placed it in a function –

    function write_custom_admin_message($message = null, $class = 'updated'){
	if($message === null)
		return;
	echo '<div id="message0" class="'.$class.' fade">';
	echo '<p><strong>'.$message.'</strong></p>';
	echo '</div>';
}

    but the problem is that I am having trouble getting my message to the function.

    I am using tha action add_action('admin_post_save_services_options', array(&$this, 'on_save_changes')); to call the function on_save_changes() when the user clicks the ‘Save changes’ button, and I can do all my validation etc in there, but then I don’t know of a way of passing the values for the message box to the main plugin function.

    function on_save_changes(){
	if(!current_user_can('manage_options'))
		wp_die( __('Cheatin’ uh?'));
	check_admin_referer('my-admin-referrer');

	if(isset($_POST['action']) === true){
		$options_name['title'] = $_POST['title'];
		$options_name['text'] = $_POST['text'];
		$options_name['image'] = $_POST['image'];

		update_option('options_name', $options_name);

		$message = __('Settings saved.');
		$class = 'updated';
	}
	wp_redirect($_POST['_wp_http_referer']);
}

    I hope all that makes sense, and I’d be very greatful if someone could help.

    Thanks.

    Ok, sorted it in a pretty simple way I think.

    The on_save_changes() function becomes this –

    function on_save_changes(){
	if(!current_user_can('manage_options'))
		wp_die( __('Cheatin’ uh?'));
	check_admin_referer('my-admin-referrer');

	if(isset($_POST['action']) === true){
		$options_name['title'] = $_POST['title'];
		$options_name['text'] = $_POST['text'];
		$options_name['image'] = $_POST['image'];

		update_option('options_name', $options_name);

		$message = 0
}
$_POST['_wp_http_referer'] = add_query_arg('message', $message_num, $_POST['_wp_http_referer']);
	wp_redirect($_POST['_wp_http_referer']);
}

    I add this to functions.php –

    function custom_plugin_messages(){
	$messages['example-plugin'] = array(
		0 => __('Settings saved.')
	);
	return $messages;
}

    and finally pop this in just below the Page title in the on_show_page() function – 

    <?php
$messages = custom_plugin_messages();
write_custom_admin_message($messages[$_GET['page']][$_GET['message']], $class);
?>

    In my settings page HTML for my plugin or theme, I just add the following line of code where I want the message to appear:

    <?php if( isset($_GET['settings-updated']) ) { ?>
    <div id="message" class="updated">
        <p><strong><?php _e('Settings saved.') ?></strong></p>
    </div>
<?php } ?>

    If you want to display an error message, check the value of $_GET[‘settings-updated’] to see if it’s true or false and if it’s false, set the class to ‘error’ instead of ‘updated’ on the div.
