Gallery Only Displaying One Thumbnail

Question

My image galleries are showing only one thumbnail in the post the gallery sits in. http://themeforward.com/demo2/2013/03/08/image-gallery/

My single.php markup can be found here: http://snippi.com/s/akm5jb7

Additionally, previous_image_link and next_image_link are not displaying when the image is clicked (these would lead to the other images in the gallery).

My entire image.php markup can be found here: http://snippi.com/s/ajwa5yh

My gallery shortcode: [gallery link="post" ids="2245,2246,2247"]

Answer 1

Try this and verify that the attachments come back correctly when queried directly:

// helper function to return first regex match
function get_match( $regex, $content ) {
    preg_match($regex, $content, $matches);
    return $matches[1];
} 

// Extract the shortcode arguments from the $post
$shortcode_args = shortcode_parse_atts(get_match('/\[gallery\s(.*)\]/isU', $post->post_content));

// get the attachments specified in the "ids" shortcode argument
$attachments = get_posts(
    array(
        'include' => $shortcode_args["ids"], 
        'post_status' => 'inherit', 
        'post_type' => 'attachment', 
        'post_mime_type' => 'image', 
        'order' => 'menu_order ID', 
        'orderby' => 'post__in', //this forces the order to be based on the order of the "include" param
    )
);

echo 'gallery count:' . count( $attachments );

If that count is correct, then the gallery shortcode should be returning correctly. Let me know what that returns.

It ended up being a problem with a code to pull a custom number of posts via an options panel.
