功能的add_filter

我有加密功能的內容：功能的add_filter

function rewrite_text($article, $case_sensitive=false) { 

    $workwith=$article; 
    *(hide line code for copyright)....(hide line code for copyright)* 
    $codul='<script type="text/javascript"> 
document.write(String.fromCharCode('.$numbers.')); 
</script>'; 
     $workwith=$codul; 
     } 
    return $workwith; 
} 
add_filter('the_content', 'rewrite_text', 100);

在我的wordpress主題（deTube wordpress主題）有作秀YouTube播放器的功能（在THEME_NAME/functions.php中）：

function dp_video($post_id, $autoplay = false) {  
    $file = get_post_meta($post_id, 'dp_video_file', true); 
    $file = !empty($file) ? explode("\n", $file) : array(); 
    $url = trim(get_post_meta($post_id, 'dp_video_url', true)); 
    $code = trim(get_post_meta($post_id, 'dp_video_code', true)); 
    if(!empty($code)) { 
     $code = do_shortcode($code); 
     if(function_exists('jwplayer_tag_callback')) 
      $code = jwplayer_tag_callback($code); 
     $code = extend_video_html($code, $autoplay);   
     echo '<div class="video-wrap">'.$code.'</div>'; 
    } elseif(!empty($url)) { 
     $youtube_id = getYouTubeIdFromURL($url); 
     $video = "<div class=\"video-wrap\"><embed src=\"http://www.youtube.com/v/".$youtube_id."?modestbranding=1&version=3&hl=vi_VN&rel=0&autoplay=1&showsearch=0&iv_load_policy=3&theme=light\" type=\"application/x-shockwave-flash\" allowFullScreen=\"true\" allowScriptAccess=\"always\" width=\"100%\" height=\"100%\"/></div>"; 
     echo $video;

我想通過函數的add_filter到dp_video加密Youtube鏈接（YouTube播放器代碼），使用：

add_filter('dp_video', 'rewrite_text', 100);

但它不工作！你能幫我添加過濾器的dp_video函數嗎？非常感謝！

如果你做add_filter('dp_video')必須有apply_filters('dp_video')某處。如果您想過濾$視頻，例如您可以將最後一行更改爲

echo apply_filters('dp_video', $video);
