I am on a roll answering everyone’s questions today so here we go with another…
This function will run every time a field is updated to check if your field needs to be checked. If your field is found it checks the value to see if it has changed since last update. If it has it will run your api call and update the other fields necessary as declared by you.
function my_acf_update_value( $value, $post_id, $field ) {
// only do it to certain custom field
if( $field['name'] == 'custom_field_name' ) {
// get the old (saved) value
$old_value = get_field('custom_field_name', $post_id);
// get the new (posted) value
$new_value = $_POST['acf']['field_1234567890abc'];
// check if the old value is the same as the new value
if( $old_value != $new_value ) {
// do your api call functions and return you size and what not
update_field('sizeField',$sizeValue, $post_id);
}
}
// don't forget to return to be saved in the database
return $value;
}
// acf/update_value - filter for every field
add_filter('acf/update_value', 'my_acf_update_value', 10, 3);
