Question

我使用symfony和doctrine。所以我使用this教程（google cache）。所以我有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);

}

好的，这个方法有效。但我想为子类别而不是为子类别做同样的事情，我想为图像形式制作它。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);


  }

但是通过这种方式我的形象无论如何都没有形成。

只需：

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

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

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

                }
