Select posts for loop based on whether an array contains value or not

Hi, I’ve got a couple of custom posts that all contain the custom field ‘assigned_page’, which is an array of strings containing page id’s. I want to run a loop and select the posts that have the current page ID in their custom array. I can’t get it to work properly, I wonder what I’m doing wrong. Here’s my code:

	// Get the current page ID
	global $post;
	$current_page = $post->ID;
	$int = (int)$current_page;
	$string_page = (string)$current_page;
	$current_parent_page = $mv_is_subpage->ID;
	
	// Post selection
	
	$args = array (
		'post_type'      => $post_type,
		'posts_per_page' => $posts_per_page,
		'orderby'        => $orderby, 
		'order'          => $order,
		'no_found_rows'  => 1,
//		'category_name' => 'test'
		'meta_query' => array( 
		array(
					'meta_key' => 'assigned_page', 
					'meta_value' => $string_page, 
					)
				),
		);

Then I just run the loop, but it’s actually returning all posts. What am I doing wrong?

Thanks all in advance

Hi,

Try this:

global $post;
	$current_page = $post->ID;
	$int = (int)$current_page;
	$string_page = (string)$current_page;
	$current_parent_page = $mv_is_subpage->ID;
	
	// Post selection
	
	$args = array (
		'post_type'      => $post_type,
		'posts_per_page' => $posts_per_page,
		'orderby'        => $orderby, 
		'order'          => $order,
		'no_found_rows'  => 1,
//		'category_name' => 'test'
		'meta_query' => array( 
			array(
				'key' => 'assigned_page', 
				'value' => "$string_page",
				'compare' => 'LIKE' 
			)
		),
	);

Also you have some strange parameters such as “no_found_rows” and “category_name” which does not exist in the wp_query class.. These should probably be removed if you dont know what you’re doing with them.. And make sure that your variables such as $order etc. is set!
