WP Custom Query using Checkbox Meta Value

I am trying to create two custom queries for a custom post type (CPT) on my Wordpress site. I have added a custom metabox to my CPT which has a single checkbox. In my first query, I am listing all the posts for my CPT that has the checkbox selected. Here is my code:

<?php 

	$args = array(
		'post_type' => 'my-custom-post-type', 
		'posts_per_page' => -1,
		'meta_query' => array( 
			array( 
				'key' => 'meta-checkbox', 
				'value' => 'on' 
			)
		)
	);

	$myposts = get_posts($args);

	if($myposts) {

		echo '<ul>';

		foreach($myposts as $mypost) {
			echo '<li>' . get_the_title($mypost->ID) . '</li>';
		}

		echo '</ul>';
	}

?>

Open in new window

This is working which is great. However, what I'm looking to do with my second query is list all the posts from my CPT that do not have the checkbox selected. I thought this would be straightforward but I just can't seem to get this to work (since not selecting the checkbox does not produce a meta value to reference).

Any help would be greatly appreciated. Thanks!

- You should always save all your metabox fields regardless on their values.
- Put all the various settings (fields) of a metabox into an array, and have only one record in database for all your metabox values.

Thanks for the reply @eemit. However, I'm not sure if I understand what it is you are suggesting I do.

When a checkbox is selected within a metabox, it is given a meta_value of "on". If the checkbox is not selected, there is no value assigned for that field. So I don't really understand what you mean by your comment:
You should always save all your metabox fields regardless on their values.
Also, as mentioned in my question, I have one metabox with one checkbox field—that's all. So I don't believe there is a need to create an array.

Can you clarify your suggestions if I'm misunderstanding anything?

Try 'meta_compare' => 'NOT EXISTS' e.g.:

	$args = array(
		'post_type' => 'my-custom-post-type', 
		'posts_per_page' => -1,
		'meta_query' => array( 
			array( 
				'key' => 'meta-checkbox', 
				'value' => 'on',
				'compare' => 'NOT EXISTS' 
			)
		)
	);
