I am facing a similar problem even after trying the new code. I am getting the following warning- “PHP Warning: Invalid argument supplied for foreach() in ***/httpdocs/wp-content/plugins/lightbox/lightbox.php on line 211
My current code is:
function get_images_url(){
global $wpdb;
$image_urls = $_POST[‘urls’];
$all_urls = array();
foreach ($image_urls as $image_url) {
$query = $wpdb->prepare(“SELECT ID FROM $wpdb->posts WHERE guid=’%s'”, $image_url);
$id = $wpdb->get_var($query);
$attachment = get_post( $id );
$description = $attachment->post_content;
array_push($all_urls,$description);
}
echo json_encode($all_urls);
die();
}
Could you help with which code to use. Thanks!
