I solved my problem re-reading ACF’s custom fields documentation. Instead of meta_query, I should’ve used meta_key. The correct argument for a custom field is: // args $args = array( ‘numberposts’ => -1, ‘post_type’ => ‘event’, ‘meta_key’ => ‘location’, ‘meta_value’ => ‘Melbourne’ );

Something like this: $ck = get_post_custom_keys($post_id); //Array // drop keys starting with ‘_’ $ck = array_filter($ck, function($key){ return strpos($key, ‘_’) !== 0; }); // store your root keys here $data = array(); foreach($ck as $k){ $cv = get_post_custom_values($k, $post_id ); //Array // drop empty values $cv = array_filter($cv); if($cv) $data[$k] = $cv; } if($data){ // … Read more
The code doesn’t seem syntactical wrong in the first place. What kind of field type are you using? Relationship? Also why are you overriding $post_object and where does it come from in the first place? That part of the code is missing. To get the field which is attached to the current post (inside the … Read more
I have managed to fix it at my own. I have used following code to update post meta update_post_meta($post_id, ‘tb_data’, base64_encode(serialize($new_value_array))); …and following code to get post meta $tb_meta = get_post_meta($post->ID, ‘tb_data’, true); $tb_meta_unserialized = unserialize(base64_decode($tb_meta)); I hope this will help someone.
