Hi,

Thanks. I’ve already read that article and although it is very important it is not what I was looking for.

I’m trying to enforce a certain logic before the post is saved, for example let’s say that I’m using WordPress to keep track of my animals in a small zoo. I have a custom post type called “animal” that contains a list of custom fields assigned to it like name, id, herbivorous_food, carnivorous_food. This custom post type also has custom taxonomy assigned to it called “prey_type” and contains three possible values like herbivorous, carnivorous and omnivorous.

Now, for example, if I’m currently creating a post for a fox, I’ll write fruits and seeds in the herbivorous_food and mice and rats under carnivorous_food and I’ll select omnivorous in the prey_type taxonomy.

What I need is a way to verify that if both fields (herbivorous_food and carnivorous_food) contain value the user will get an alert when he/she tries to save the post unless the only taxonomy that is selected is omnivorous, and if only carnivorous_food contains value than the user will get an alert when he/she tries to save the post unless the only taxonomy that is selected is carnivorous and so on.

Is that possible? If so – how?

I think that I finally understood what you meant and change the sygnia_filter_best_practices function (which is hooked to the parse_query filter) to this:

function sygnia_filter_best_practices( $query ) {
global $pagenow;
// Get the post type
//modify the query only if it admin and main query.
if( !(is_admin() AND $query->is_main_query()) ){
return $query;
}

//we want to modify the query for the targeted custom post and filter option
if( !(‘best_practice’ === $query->query[‘post_type’] AND isset($_REQUEST[‘pillar_filter’]) ) ){
return $query;
}

$post_type = isset( $_GET[‘post_type’] ) ? $_GET[‘post_type’] : ”;
if ( is_admin() && $pagenow==’edit.php’ && $post_type == ‘best_practice’ && isset( $_GET[‘pillar_filter’] ) && $_GET[‘pillar_filter’] !=’all’ ) {
$query->query_vars[‘meta_key’] = ‘pillar’;
$query->query_vars[‘meta_value’] = $_GET[‘pillar_filter’];
$query->query_vars[‘meta_compare’] = ‘=’;
// var_dump($query);
// error_log(var_export($query, true));
}
}

and now it seems that it works correctly. thanks a lot!
Now, I have few more questions but to keep everything neat I’ll post them as new tickets.

Thanks a lot for all your help!
