It’s possible. You have to get the images attached to the post with:
$args = array(
'post_type' => 'attachment',
'post_parent' => $post->ID,
'post_status' => 'inherit',
'post_mime_type' => 'image',
);
Query them
$attachments = new WP_Query( $args );
$attachments->get_posts();
$output = '';
foreach( $attachments->posts as $attachment ) {
$image_src = wp_get_attachment_image_src( $attachment->ID, 'large');
$output .= '<a href="'. $image_src[0] .'" rel="lightbox[post-1]" class="hidden"></a>';
}
Where you have your featured image, you also link to the image src of the thumbnail:
<?php
$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' );
?>
<a href="<?php $image[0]; ?>" rel="post-1">
the_post_thumbnail( 'thumbnail-size');
</a>
Then you have to load the JavaScripts in your functions.php, take a look at wp_enqueue_script()
Forgotten the backticks
<a href="<?php $image[0]; ?>" rel="post-1">
should be
<a href="<?php $image[0]; ?>" rel="lightbox[post-1]">
sorry to be a pain in the neck…
here is my loop
<ul>
<?php $posts = query_posts( $query_string . 'order=asc' ); ?>
<?php if (have_posts()): while (have_posts()): the_post(); ?>
<li><a href="<?php the_permalink() ?>"><?php the_post_thumbnail(); ?></a></li>
<?php endwhile; endif; ?>
</ul>
I’m not sure where all the code you posted goes……
OK, I’m about halfway there!
Here is my revised loop:
[Code moderated as per the Forum Rules. Please use the pastebin]
my output is :
<a href="" rel="lightbox[post-1]">
<img width="113" height="113" src="http://myserver.net/files/2012/02/rob_TN.jpg" class="attachment-thumbnail-size wp-post-image" alt="rob_TN" title="rob_TN" /></a>
<a href="" rel="lightbox[post-1]">
<img width="113" height="113" src="http://myserver.net.net/files/2012/02/nes_TN.jpg" class="attachment-thumbnail-size wp-post-image" alt="nes_TN" title="nes_TN" /></a>
<a href="" rel="lightbox[post-1]">
<img width="113" height="113" src="http://myserver.net.net/files/2012/02/1.gif" class="attachment-thumbnail-size wp-post-image" alt="1" title="1" /></a>
How do i:
-get it to actually return the URL of the image?
– get the rel=”lightbox[post-1]” to return the ID of the post, instead of 1?
