Hi @jgraup
Yes, the function contains a loop which would run when the posts__in arg is supplied (this is used by ACF):
// array of post ids
137 // post_parent__in & post_parent__not_in since WP 3.6
138 foreach (array('post__in', 'post__not_in', 'post_parent__in', 'post_parent__not_in') as $key) {
139 $arr = array();
140 if (!empty($qv[$key])) {
141 // post__in used by the 2 functions below
142 // useless to filter them as output is already in the right language and would result in performance loss
143 foreach (debug_backtrace() as $trace)
144 if (in_array($trace['function'], array('wp_nav_menu', 'gallery_shortcode')))
145 return;
146
147 foreach ($qv[$key] as $p)
148 $arr[] = ($tr = pll_get_post($p)) ? $tr : $p;
149
150 $qv[$key] = $arr;
151 }
152 }
I’m not sure what the code does exactly, but it looks to modify the id’s.
I would advise that you debug this function by printing out the $qv varible before and after this loop. This will show what has changed:
Thanks
