In reply to Dave McCourt. Thanks for this approach. You could also use output buffering (ob_start, ob_get_contents) to get the output without changing much of the code.

In reply to Bart McLeod. Well actually, the 'include' index is present, but the value is empty.

Thanks for your post! I needed to know what to do if no ‘include’ index is present when loading the images and your example makes it quite clear.

In reply to ket. Ket, if you return the output and the use the_content() filter, it works inline (ie wherever you put your gallery in the post editor):


remove_shortcode('gallery');
add_shortcode('gallery', 'parse_gallery_shortcode');

function gallery_output_in_the_content($content) {
	$g = parse_gallery_shortcode();
	$custom_content = $g;
	$custom_content .= $content;
	return $custom_content;
}

add_filter('the_content', 'gallery_output_in_the_content');

function parse_gallery_shortcode($atts) {
… as above but with this extra code:

   $gal .= '';

   foreach ($images as $image) {     
        $caption = $image->post_excerpt;
 
        $description = $image->post_content;
        if($description == '') $description = $image->post_title;
 
        $image_alt = get_post_meta($image->ID,'_wp_attachment_image_alt', true);
 
        // render your gallery here
        $gal .=  '';
        $img_meta = wp_get_attachment_metadata($image->ID);
        $img = wp_get_attachment_image_src($image->ID, 'gallery-small');
        $img_big = wp_get_attachment_image_src($image->ID, 'gallery-big');
        $gal .=  '';
        if (strlen($caption) > 0) $gal .= '' . $caption . '';
        $gal .=  '';
    }
    
    $gal .=  '';
       
    return $gal;    
}

This looks like a great solution, but when I activate the plugin, all the images in the editor’s Media popup disappear. Any idea why this might be happening?

In reply to Nicholas.

This is an older article, written before the 3.5 update where individual image ids are specified, rather than using the parent-attach system. Refer to http://codex.wordpress.org/Gallery_Shortcode for a summary of shortcode history and the old vs. new media flow.

ADD: I have just updated the article above to handle id lists.

Hey I don’t mean to criticize but your code is really not doing the right thing. Firstly as some other comments shared, you are pulling all attachments inside the post, not just from that gallery. The other problem with doing this is the function will no longer respects the order by which the images were set up in the gallery; it is passed as $atts to the shortcode function but disregarded completely.
