在symfony中，如何设置表单字段的值？

I'm overriding my doSave() method to basically do the following: I have a sfWidgetFormPropelChoice field that the user can either choose from, or type a new option. How can I change the widget's value? Or maybe I am approaching this the wrong way. So here is how I overrode the doSave() method:

我正在覆盖我的doSave()方法基本上执行以下操作:我有一个用户可以选择的sfWidgetFormPropelChoice字段,或者键入一个新选项。如何更改小部件的值?或许我接近这个错误的方式。所以这是我如何覆盖doSave()方法:

public function doSave($con = null)
{
    // Save the manufacturer as either new or existing.
    $manufacturer_obj = ManufacturerPeer::retrieveByName($this['manufacturer_id']->getValue());
    if (!empty($manufacturer_obj))
    {
        $this->getObject()->setManufacturerId($manufacturer_obj->getId()); // NEED TO CHANGE THIS TO UPDATE WIDGET'S VALUE INSTEAD?
    }
    else
    {
        $new = new Manufacturer();
        $new->setName($this['manufacturer_id']->getValue());
        $new->save();
        $this->getObject()->setManufacturerId($new->getId()); // NEED TO CHANGE THIS TO UPDATE WIDGET'S VALUE INSTEAD?
    }

    parent::doSave($con);
}

3 个解决方案

#1

You should use setDefault or setDefaults and then it will autopopulate with the bound values.

您应该使用setDefault或setDefaults然后它将使用绑定值自动填充。

(sfForm) setDefault ($name, $default)
(sfForm) setDefaults ($defaults)

usage

$form->setDefault('WidgetName', 'Value');
$form->setDefaults(array(
    'WidgetName' => 'Value',
));

You could do it in the action :

你可以在行动中做到:

$this->form->getObject()->setFooId($this->foo->getId()) /*Or get the manufacturer id or name from request here */
$this->form->save();

But I prefer to do the kind of work you are doing with your manufacturer directly in my Peer so my business logic is always at the same place.

但我更喜欢直接在我的Peer中与制造商一起做的工作,所以我的业务逻辑总是在同一个地方。

What I put in my forms is mainly validation logic.

我在表单中添加的主要是验证逻辑。

Example of what to put in the save method of the Peer :

在Peer的save方法中放入什么的示例:

public function save(PropelPDO $con= null)
{
  if ($this->isNew() && !$this->getFooId())
  {
    $foo= new Foo();
    $foo->setBar('bar');
    $this->setFoo($foo);
   } 
}

Two assumption here: a) your form gets the name of the manufacturer and b) your model wants the ID of a manufacturer

这里有两个假设:a)您的表单获取制造商的名称,b)您的模型需要制造商的ID

public function doSave($con = null)
{
    // retrieve the object from the DB or create it
    $manufacturerName = $this->values['manufacturer_id'];
    $manufacturer = ManufacturerPeer::retrieveByName($manufacturerName);
    if(!$manufacturer instanceof Manufacturer)
    {
        $manufacturer = new Manufacturer();
        $manufacturer->setName($manufacturerName);
        $manufacturer->save();
    }

    // overwrite the field value and let the form do the real work
    $this->values['manufacturer_id'] = $manufacturer->getId();

    parent::doSave($con);
}
