 I have trouble with my theme Constructor - I write following code for
 register stylesheet generated by PHP:

 {{{
 wp_enqueue_style( 'constructor-custom-style', get_option('home').'/?theme-
 constructor=css');
 }}}

 But this is code doesn't work with theme preview, because correct url for
 preview is '/?theme-constructor=css&preview=1&template=constructor'

 I found simple solution, but this is requried changes of Wordpress source
 code in file wp-includes/theme.php:

 {{{
 function preview_theme_ob_filter( $content ) {
     // apply new filter
     $content = apply_filters('preview_theme_ob_filter', $content); // add
 filter for preview content
     return preg_replace_callback( "|(<a.*?href=([\"']))(.*?)([\"'].*?>)|",
 'preview_theme_ob_filter_callback', $content );
 }
 }}}

 I can use this is filter in my function.php:

 {{{
 function constructor_preview($content) {
    $link = add_query_arg(array('preview' => 1, 'template' =>
 get_template()), '?theme-constructor=css');
    $content = str_replace('?theme-constructor=css', $link, $content);
    return $content;
   }
 add_filter('preview_theme_ob_filter', 'constructor_preview');
 }}}
