Thesis Theme 1.5 with Wordpress 2.8

I’ve been playing with the newest version of WordPress (2.8), which is due to be released in the near future. It features a completely new way of writing Widgets, so I've been testing that out.

I discovered a clash with my favourite wordpress theme, the Thesis framework.  Took me a little while to figure it out, but I think I've solved the problem.

The problem

Wordpress 2.8 features an excellent Widget manager in the admin area.  But with Thesis 1.5, this area is unusable.  Widgets cannot be dragged/dropped, which is essential.  It seems that the JS provided by Thesis clashes with JS provided by Wordpress on a few different screens.

The fix

Open up your Thesis files, and look in /lib/admin/admin.php.   Look for function thesis_options_js()

$date_modified_js = filemtime(THESIS_SCRIPTS . '/thesis.js'); 
$date_modified_ui = filemtime(THESIS_SCRIPTS . '/jquery-ui.js'); 
echo '<script type="text/javascript" src="' . THESIS_SCRIPTS_FOLDER . '/thesis.js?d=' . date('mdy-Gms', $date_modified_js) . '" /></script>' . "\\n"; 
echo '<script type="text/javascript" src="' . THESIS_SCRIPTS_FOLDER . '/jquery-ui.js?d=' . date('mdy-Gms', $date_modified_ui) . '" /></script>' . "\\n";

Thesis comes with its own jQuery UI script, which clashes with the in-built wordpress scripts.  Replace that function with this one:

if (!is_admin()) { return; } 
$date_modified_js = filemtime(THESIS_SCRIPTS . '/thesis.js'); 
$date_modified_ui = filemtime(THESIS_SCRIPTS . '/jquery-ui.js'); 
wp_enqueue_script('jquery-ui-core'); 
wp_enqueue_script('jquery-ui-sortable'); 
wp_enqueue_script('jquery-ui-tabs'); 
wp_enqueue_script('thesis-admin-js', THESIS_SCRIPTS_FOLDER.'/thesis.js');

Also look for the function thesis_admin_styles_and_scripts()

It contains this:

add_action('admin_head', 'thesis_options_stylesheet'); 
add_action('admin_head', 'thesis_options_js');

Replace with this:

add_action('admin_head', 'thesis_options_stylesheet'); 
add_action('admin_head', 'thesis_options_js'); 
add_action('init', 'thesis_options_js');

And problem solved!  So far I haven't discovered any unwanted side-affects.  You may only need to enqueue jquery-ui-sortable.
