I am trying to display all the images attached to a wordpress post and link the image to the source of the image to open it in a light box. I am using the following code:
if (have_posts())
{ while (have_posts()) { the_post(); $args = array( 'orderby' => 'title', 'order' => 'ASC', 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => $post->ID, 'exclude' => get_post_thumbnail_id() ); $attachments = get_posts( $args ); if ($attachments) { foreach ($attachments as $attachment) { ?> <div> <a rel="lightbox" href="<?php /* ??? */ ?>"> <?php echo wp_get_attachment_image ($attachment->ID, 'full'); ?> </a> </div> <?php } } }
}I have tried many things where the ??? but i can't seem to retrieve just the source url.
Can anyone provide some insight?

Use wp_get_attachment_image_src
This:
wp_get_attachment_image_src( $attachment->ID, 'full' );should return an array with the following elements
[0] => url
[1] => width
[2] => height
[3] => boolean: true if $url is a resized image, false if it is the original or if no image is available.If you just want to link to the original full image it's better to simply use "wp_get_attachment_url" -
The wp_get_attachment_image_src function will run code you don't need and return extra details you don't need making your code less efficient.
