Call custom post page based on meta value

Hi everyone,

I have done a lot of searching and a lot of attempts but having some trouble getting this to work.

I have a custom post type called price. In here I have a custom meta box that lists all the pages within my website along with a checkbox. What happens is admin creates a price and then assigns it to multiple pages by ticking the checkbox.

So what I have in the database in wp_postmeta is a meta_key called ‘ap_linkto_page’ and a list of page ids e.g. ‘7,86,16,12’.

Now for each page on the the front-end I need to list the prices but only the prices that are assigned to the page we are on. So the above price is attached to page id 7,86,16,12 so if I am on any of those pages I need to show the price.

Any ideas how I can get this to work? This is all I have but it just lists all prices.

if (count($arr) > 0)
{
	$i = 1;
	$args = array(
		'post_type'		 => 'price',
		'posts_per_page'	=> -1,
		'orderby'		   => 'menu_order'
        );
        $prices = get_posts($args);
	foreach($prices as $price)
        {
		echo $price->post_title;
	}
}

I think I need to explode the array of ids and add the id in to the args somehow. Any ideas?
