This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WP Multibox


The Multibox script by phatfusion, further improved by Liam Smart is probably the best lightbox option within the MooTools framework.
It handles images, flash video and swf, ajax and remote html, realmedia, windows media, pdf and mp3 playback, with automatic slideshows.
Colors, borders and custom icon folder could be set directly on the settings page.

Since the first porting of the script as a WordPress plugin, by Manfred Rutschmann, is no longer updated, this release is purposed to load the script with wp_enqueue_script function in order to avoid conflicts.
In addition, inline elements, Ajax requests and the latest MooTools framework version 1.3 are supported!

Problems with JavaScript

How can I open a post from my blog into the multibox?

Enable the WordPress AJAX feature in the plugin settings. Set the attribute ‘rel=”wpajax:true”‘ in the trigger link.
Set the ID of the link to: ‘yourclass’+’-ajax-‘+’targetpost->ID’
e.g. “wmp-ajax-42”, or “lightbox-ajax-536”
Multibox will connect to the WordPress native AJAX gateway (admin-ajax.php) and display the post content.
Automatic retrieval of the post ID and content, from a given slug/URL, will be implemented in a future release.

Can I manually open links in the multibox?

Yes. When you make a link in the editor of wordpress, use the ‘class=”wmp”‘ tag. Example to
open Google in a window: a class=”wmp” rel=”width:600,height:500″ href=””
When you make use of the rel=”” tag, you can set width and height of the multibox frame.

Can I set a title and description that is displaying only in the multibox?

Yes: insert an image in your post and click on the settings button of the image. Go to the “advanced” tab and fill out the title and description fields.

Could the plugin work with image gallery plugins such as Nextgen or Cleaner Gallery?

Yes: make it use “wmp” or the same class name specified in the WP Multibox settings panel and disable other built-in lightbox scripts.
