// a field array( 'id' => 'gallery_2', 'type' => 'gallery', 'title' => 'Logos of the happy clients', 'add_title' => 'Add Images', 'edit_title' => 'Edit Images', 'clear_title' => 'Remove Images', ),

$meta_data = get_post_meta( get_the_ID(), 'section_testimonial', true ); $gallery = $meta_data['gallery_2']; if ( ! empty( $gallery ) ) { $ids = explode( ',', $gallery ); foreach ( $ids as $id ) { $attachment = wp_get_attachment_image_src( $id, 'full' ); ?> <li data-sr='enter top, wait 0.2s'><img src="<?php echo $attachment[0]; ?>" alt=""></li> <?php } }
