In symfony, how to set the value of a form field?
提问by James Skidmore
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() 方法以基本上执行以下操作：我有一个 sfWidgetFormPropelChoice 字段，用户可以从中进行选择或键入新选项。如何更改小部件的值？或者也许我以错误的方式接近这个。所以这里是我如何覆盖 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);
}

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
用法
$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 中与制造商一起做那种工作，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.
我放在表单中的主要是验证逻辑。
Example of what to put in the save method of the Peer :
在 Peer 的 save 方法中放入内容的示例：
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);
}
