CakePHP的組件錯誤

Question

我在我的應用程序這個組件：

class ImageComponent extends Component { 


var $image; 
var $image_type; 

function __construct($filename = null){ 
    if(!empty($filename)){ 
     $this->load($filename); 
    } 
} 

function load($filename) { 
    $image_info = getimagesize($filename); //<<== LINE OF THE ERROR 
    $this->image_type = $image_info[2]; 
    if($this->image_type == IMAGETYPE_JPEG) { 
     $this->image = imagecreatefromjpeg($filename); 
    } elseif($this->image_type == IMAGETYPE_GIF) { 
     $this->image = imagecreatefromgif($filename); 
    } elseif($this->image_type == IMAGETYPE_PNG) { 
     $this->image = imagecreatefrompng($filename); 
    } else { 
     throw new Exception("The file you're trying to open is not supported"); 
    } 

} 
} 

但是，當我剛剛加載組件，我收到此錯誤：

getimagesize() expects parameter 1 to be string, object given [APP/Controller/Component/ImageComponent.php, line 33] 

感謝

的構造一個組件期望第一個參數是一個ComponentCollection對象。在一個側面說明 - 這是一個代碼味道改變父母的類功能的參數類型
