Symfony在管理生成器中嵌入图像形式

Question

我使用symfony和doctrine。所以我用this教程（google cache）。所以我有我的下一个类别和子类别：

if (!$this->isNew()) { 

    // embed all subcategory forms 
    foreach ($this->getObject()->getSubcategory() as $subcategory) { 

    // create a new subcategory form for the current subcategory model object 
    $subcategory_form = new SubcategoryForm($subcategory); 

    // embed the subcategory form in the main category form 
    $this->embedForm('subcategory'.$subcategory->getId(), $subcategory_form); 

    // set a custom label for the embedded form 
    $this->widgetSchema['subcategory'.$subcategory->getId()]->setLabel('Subcategory:'. $subcategory->getName()); 

} 

$subcategory_form = new SubcategoryForm(); 

    // embed the subcategory form in the main category form 
$this->embedForm('subcategory', $subcategory_form); 

public function bind(array $taintedValues = null, array $taintedFiles = null) { 

    $this->languages = sfConfig::get('app_cultures_enabled'); 

    $langs = array_keys($this->languages); 

     foreach($this->languages as $lang => $label) 
      { 
    // remove the embedded new form if the name field was not provided 
    if (is_null($taintedValues['subcategory'][$lang]['name']) || strlen($taintedValues ['subcategory'][$lang]['name']) === 0) { 

     unset($this->embeddedForms['subcategory'], $taintedValues['subcategory']); 

     // pass the new form validations 
     $this->validatorSchema['subcategory'] = new sfValidatorPass(); 

    } else { 

     // set the category of the new subcategory form object 
     $this->embeddedForms['subcategory']->getObject()-> 
       setCategory($this->getObject()); 

    } 
      } 

    // call parent bind method 
    parent::bind($taintedValues, $taintedFiles); 

} 

好，所以这种方法的工作原理。但是我想为了子类而不是做同样的事，我想把它做成图像形式。所以我有下一个：

if (!$this->isNew()) { 

       // Image 

        foreach ($this->getObject()->getImage() as $image) { 

          $image_form = new ImageForm($image); 
          $this->embedForm('image'.$image->getId(), $image_form); 

       } 


       $image_form = new ImageForm(); 

       $this->embedForm('image', $image_form); 

public function bind(array $taintedValues = null, array $taintedFiles = null) { 

    if (is_null($taintedValues['image']['image'])|| strlen($taintedValues['image']['image']) === 0) { 

        unset($this->embeddedForms['image'], $taintedValues['image']); 

        // pass the new form validations 
        $this->validatorSchema['image'] = new sfValidatorPass(); 

       } else { 

          // set the category of the new subcategory form object 
          $this->embeddedForms['image']->getObject()-> 
          setProduct($this->getObject());       
    } 
parent::bind($taintedValues, $taintedFiles); 


    } 

但这样我的图像形式以任何方式未设置。

只是要：

if ((''== $taintedFiles['image']['image']['name'])) { 

        unset($this->embeddedForms['image'], $taintedValues['image'],$taintedFiles['image']); 

        // pass the new form validations 
        $this->validatorSchema['image'] = new sfValidatorPass(); 

       }
