plugin's script and style enqueing not working on Thesis

I've published a plugin on WP repository that allows some theming for Gravity Forms.

This plugin as been tested with Twenty Ten, and Twenty Eleven. When I've tried to test it in a site that uses Thesis 1.8.5, I've found out that something wasn't working.

What this plugin does is to extend the Gravity Forms shortcode with a new action. When this action is called, the whole form is wrapped in a div with an appropriate class, then in this case the plugin includes a skin's function.php for further customizations.

Basically the plugin checks two directories: - /themes directory inside the plugin directory - /mgft-themes directory inside /wp-content

For both directories, it lists all subdirectories and consider them as available themes.

When a GF shortcode has a 'theme' action and a 'themename' value, my plugin check what is available in the selected theme folder: - It enqueue all *.js and *.css files located in theme's root - It includes all *.php files located in theme's root

For the moment I always have a functions.php file like this:

wp_enqueue_style("misamee-themed-form-$theme[name]", "$theme[url]css/misamee.themed.form.$theme[name].css");
wp_enqueue_script('tooltipsy', "$theme[url]js/tooltipsy.min.js", array('jquery'));
wp_enqueue_script("misamee-themed-form-$theme[name]-js", "$theme[url]js/misamee.themed.form.$theme[name].js", array('jquery'));

This function.php is included as such (you can grab the full code here):

1. __construct()

   add_filter("gform_shortcode_theme", array($this, "misamee_themed_form_theme"), 10, 3);
   

2. The misamee_themed_form_theme method:

   function misamee_themed_form_theme($string, $attributes, $content)
   {
   extract(shortcode_atts(array(
       'title' = true,
       'description' = true,
       'id' = 0,
       'name' = '',
       'field_values' = "",
       'ajax' = false,
       'tabindex' = 1,
       'action' = 'form',
       'themename' = '',
       'cssclass' = ''
   ), $attributes));
   
   /** @var $themename string */
   /** @var $selectedTheme string */
   $selectedTheme = $themename;
   
   /** @var $id int */
   $theme = $this-misamee_themed_form_setTemplate($selectedTheme, $id);
   
   $additionalClasses = ($theme['name'] != '') ? " class=\"themed_form $theme[name]\"" : "";
   
   //$newString = str_replace('action="prettify"', 'action="form"', $string);
   
   $attributes['action'] = 'form';
   
   $formString = RGForms::parse_shortcode($attributes, $content = null);
   //$formString = do_shortcode($newString);
   
   if ($additionalClasses != '') {
       return "div$additionalClasses$formString/div";
   }
   return $formString;
   }
   

3. $this->misamee_themed_form_setTemplate():

   private function misamee_themed_form_setTemplate($themeName, $formId)
   {
   $theme = $this-misamee_themed_form_getThemeByName($themeName);
   //echo "pre";
   if (strtolower($theme['name']) != "none") {
       if ($theme['name'] == 'default') {
           wp_enqueue_style('misamee-themed-form-css', $theme['url'] . 'css/misamee.themed.form.css');
           wp_enqueue_script('tooltipsy', $theme['url'] . 'js/tooltipsy.source.js', array('jquery'));
           wp_enqueue_script('misamee-themed-form-js', $theme['url'] . 'js/misamee.themed.form.js', array('jquery'));
       } elseif (is_dir($theme['dir'])) {
           //get all files in specified directory
           $files = glob($theme['dir'] . "/*.*");
   
           foreach ($files as $file) {
               $fileData = pathinfo($file);
               switch ($fileData['extension']) {
                   case 'css':
                       wp_enqueue_style($fileData['filename'], $theme['url'] . $fileData['basename']);
                       //echo "wp_enqueue_style('$fileData[filename]', '$theme[url]$fileData[basename]')\n";
                       break;
                   case 'js':
                       wp_enqueue_script($fileData['filename'], $theme['url'] . $fileData['basename']);
                       //echo "wp_enqueue_script('$fileData[filename]', '$theme[url]$fileData[basename]')\n";
                       break;
                   case 'php':
                       include($theme['dir'] . '/' . $fileData['basename']);
                       //echo "include($theme[dir]/$fileData[basename])\n";
                       break;
               }
           }
       }
       add_action("gform_field_css_class", array($this, "add_custom_class"), 10, 3);
   }
   return $theme;
   }
   

It works, at least with the default theme, but with Thesis, this php file doesn't seem to work. It doesn't raise any error: simply id doesn't do anything.

If I add a echo 'OK'; in this file, I can see the "OK" string in the HTML, but enqueuing doesn't work. With other themes my code works though, so I can't see how to solve this issue.

I've tried any other option, including hooking the three lines to 'wp_print_footer_scripts', 'wp_print_scripts', 'wp_enqueue_scripts', 'init' (I know I should user wp_print_* or init hooks, but desperate times, desperate measures): nothing helped.

Right now the only way to "make it work" seem to replace the wp_enqueue_* function with straight rendering of the 'script ...' and 'link ...' tags: something I really don't like.
