Get the post ID from within uwpqsf_query_args function

    Firstly, thanks for a truly awesome plugin.

    I have a custom post type called ‘instructor’.
    On single-instructor.php template, I use …
    <?php echo do_shortcode('[ULWPQSF id=125 formtitle="0"]');?>

    The form is used to filter through another custom post type called ‘tutorials’.
    So when I create a tutorial post in admin, I select an instructor using ACF’s Relationship field type so basically, the ID of a particular instructor is saved as a meta for the tutorial post.

    What I want to do is use the form on a single instructor page to filter through ONLY the displayed instructor’s tutorials. I can do this with a custom query upon page load, but as soon as I use the filter form, the results display all tutorials (also from other instructors).

    So here’s what I have so far in functions.php…

    add_filter('uwpqsf_query_args','injecting_custom_arg','', 4);
function injecting_custom_arg($args, $id,$getdata){
if($id == '125') {
    $args['meta_key'] = 'instructor';
    $args['meta_value'] = 48;
 }
  return $args;
}

    The above function accomplishes what I want but of course I need the meta_value to be dynamic instead of 48, so I need to get the post ID of the instructor that is currently being displayed. I have tried just about everything but I cannot seem to get any information from the currently displayed instructor/post from code used within this function.

    While I realise that it is probably because of not being within a loop, I am stuck and don’t know what to do.

    I have tried using…

    global $post;
echo get_the_ID();
echo $post->ID;

    Nothing is returned.
    I have also tried to get the ID from the url/slug but no luck either.

    Thank you for your help in advance.

    You need to pass the instructor id to the query. To do so, you can add a hidden input in the form.
    eg:

    add_action(‘uwpqsf_form_top’,’add_hidden_id’);

    function add_hidden_id($att){
//get the current post id
global $post;
$id = $post->ID;
echo '<input type="hidden" name="instructor" value="'.$id.'">';
}

    The above code will add a hidden input field to the form, if the search form is in a single page main while loop.

    Then you using the value in the uwpqsf_query_args:

    add_filter('uwpqsf_query_args','injecting_custom_arg','', 4);
function injecting_custom_arg($args, $id,$getdata){
//$getdata is like $_GET or $_POST, so you can use it to get the value from instructor.

if(isset($getdata['instructor'])) {
    $args['meta_key'] = 'instructor';
    $args['meta_value'] = $getdata['instructor'];
 }
  return $args;
}

    Thank you so much for your response.
    Worked flawlessly!

    Here’s my final code for anyone else wanting to do the same thing…

    add_action('uwpqsf_form_top','add_hidden_id');
function add_hidden_id($att){
//get the current post id
global $post;
$id = $post->ID;
echo '<input type="hidden" name="thepostid" value="'.$id.'">';
}

add_filter('uwpqsf_query_args','injecting_custom_arg','', 4);
function injecting_custom_arg($args, $id,$getdata){
//$getdata is like $_GET or $_POST, so you can use it to get the value from instructor.

    //On single instructor page
    if($id == '125') {
        if(isset($getdata['thepostid'])) {
            $args['meta_key'] = 'instructor';
            $args['meta_value'] = $getdata['thepostid'];
        }
    }

    //On Single Site page
    if($id == '191') {
        if(isset($getdata['thepostid'])) {
            $args['meta_key'] = 'site';
            $args['meta_value'] = $getdata['thepostid'];
        }
    }

    return $args;
}

    Thanks again!
