I have a Post Object custom field named “free_course_option” for Taxonomy terms. I’m trying to dynamically set the “Filter by Taxonomy” parameter so that when I am on the edit screen for a Taxonomy term, the taxonomy filter is set to the current term. I’ve tried using acf/load_field and acf/fields/post_object/query but have been unsuccessful with either. So far, using acf/load_field is getting me closer to accomplishing what I want. Here is the code I’ve inserted in my functions.php file:
function acf_load_course_choices( $field ) {
$screen = get_current_screen();
if( $screen->id === "edit-programs" ) {
if (isset($_GET['tag_ID'])) {
$tag_ID = $_GET['tag_ID'];
$this_program = get_term_by('id', $tag_ID, 'programs');
$this_slug = $this_program->slug;
// Filter based on which taxonomy (Program) you're currently editing
$field['taxonomy'] = array();
$field['taxonomy'][0] = 'programs:' . $this_slug;
}
}
return $field;
}
add_filter('acf/load_field/name=free_course_option', 'acf_load_course_choices');
I had a similar requirement to yours and found this when searching for a solution.
I have managed to get this working using the acf/fields/post_object/query filter.
The way it brings in the information is a bit harder to debug as it’s all AJAX, but using WP_DEBUG_LOG and error_log to see what data was parsing through helped me come to the solution:
function cxx_event_balance_individual_option( $args, $field, $post_id ) {
// $post_id comes in here as term_# so we need to remove 'term_' to get the term ID
$prefix = 'term_';
// Also if you are creating a new taxonomy, post_id = 'term_0' so then there's no point in adding a filter
if ( 'term_0' != $post_id && substr( $post_id, 0, strlen( $prefix )) == $prefix ) {
// Set $term_id to the ID part of $post_id
$term_id = substr( $post_id, strlen( $prefix ) );
// And adjust the query to filter by specific taxonomy term
$args['tax_query'] = array(
array(
'taxonomy' => 'product_event',
'field' => 'term_id',
'terms' => $term_id,
),
);
}
return $args;
}
Hope this helps you out.
@jakeodb thank you very much for your solution. I applied it to my project and it is working as intended. I guess I was on the right track when I began exploring the acf/fields/post_object/query filter, but I didn’t keep pressing on. Thanks again!
Hello, this is kind of old, but I am looking for the same thing and the solution above is not working for me. I don’t know if something changed with later versions, but is there a working solution for the latest ACF version?
