Hi
I would like to exclude posts with via the url based on a custom field and I followed this:
https://www.advancedcustomfields.com/resources/query-posts-custom-fields/
and “Dynamic $_GET parameters” which works but not if I want to exclude the post with the value.
I have a custom field called ‘members_only_video’ which is a True/False.
function my_pre_get_posts( $query ) {
// do not modify queries in the admin
if( is_admin() ) {
return $query;
}
// only modify queries for 'webinar' post type
if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'webinar' ) {
// allow the url to alter the query
if( isset($_GET['members_only_video']) ) {
$query->set('meta_query', array(
array(
'key' => 'members_only_video',
'value' => $_GET['members_only_video'],
'compare' => '!=',
)));
}
}
// return
return $query;
}
add_action('pre_get_posts', 'my_pre_get_posts');
I came a bit on the way to finding a solution.
I change the compare to:
‘compare’ => ‘NOT EXISTS’
and the query now returns the right posts but it ignores the =true =false values
The urls:
http://www.website.com/events?city=true
http://www.website.com/events?city=false
just returns the same?
$meta_query = array(
'relation' => 'AND',
array(
'key' => 'members_only_video',
'compare' => 'EXISTS'
),
array(
'key' => 'members_only_video',
'value' => $_GET['members_only_video'],
'compare' => '!='
)
);
