This filter will help to change the default thumbnail (either featured image or no image) for a custom post type item within the re-order interface.

apto_reorder_item_thumbnail

Examples:

The following code will return a custom image instead the default thumbnail:

function  theme_apto_reorder_item_thumbnail($image_html, $post_ID)
    {
        //let's use a custom field called "custom_image" which contain the media we need to show for this
        $image_url = get_post_meta($post_ID, 'custom_image', TRUE);
        if($image_url != '')
            $image_html = '<img src="'. $image_url .'" width="64" alt="" />';

        return $image_html;
    }
add_filter('apto_reorder_item_thumbnail', 'theme_apto_reorder_item_thumbnail', 10, 2);

In case the custom_image meta data is not an image url but an attachment, this code can be used instead:

function  theme_apto_reorder_item_thumbnail($image_html, $post_ID)
    {
        $image_id = get_post_meta($post_ID, 'custom_image', TRUE);        
        $image_data = wp_get_attachment_image_src($image_id, 'thumbnail');
        $image_url = $image_data[0];
        
        if($image_url != '')
            $image_html = '<img src="'. $image_url .'" width="64" alt="" />';
 
        return $image_html;
    }
add_filter('apto_reorder_item_thumbnail', 'theme_apto_reorder_item_thumbnail', 10, 2);

The following code works with the WP E-Commerce product gallery :

function  theme_apto_reorder_item_thumbnail($image_html, $post_ID)
    {
        //let's use a custom field called "custom_image" which contain the media we need to show for this
        $image_id = get_post_meta($post_ID, '_wpsc_product_gallery', TRUE);        
        $image_data = wp_get_attachment_image_src($image_id, 'thumbnail');
        $image_url = $image_data[0];
        
        if($image_url != '')
            $image_html = '<img src="'. $image_url .'" width="64" alt="" />';
 
        return $image_html;
    }
add_filter('apto_reorder_item_thumbnail', 'theme_apto_reorder_item_thumbnail', 10, 2);

*This code should be used within the theme or a custom plugin.
