I have created two posts types:
A) hostals (it has all the meta boxes for a template)
B) memberships (it has 1 meta box with Name ID “quantity“: packages that is a 3 option radio button) values are 1,5 and 10
I added a shortcode [count-posts] that links to a function that have to do the following:
1) Count how many post that USER submitted
2) Check on the assigned membership to this USER what option was picked, 1, 5 or 10.
3) Compare them. If the Count was bigger or equal to “Quantity” then the user can´t submit any other post and return “FALSE” if its less than return “TRUE”
(I am using RTO for dynamic functions, so thats already setup to hide a SUBMIT FORM/BUTTON if shortcode returns false).
I am not sure how to build this code (I put it in a custom plugin) I got this far but I am not too familiar with codes:
$args = array(
'post_type' => 'hostals', // my post type slug
'post_per_page' => -1, // get them all. I think this is ok
'post_status' => 'publish', // I think this is ok
'meta_query' => array( // <strong>STARTING THIS POINT I DONT KNOW WHAT TO DO</strong>
'key' => 'your-field-name', // HOW TO CHECK ON A META FIELD FROM ANOTHER POSTTYPE?
'compare' => 'EXISTS'
$query = new WP_Query($args);
$post_count = count($query->posts);
