[英]How to pass params from controller to Zend_Form?
I know this question is already answered here . 我知道这个问题已经在这里回答了 。 But this doesnt work for me.
但这对我不起作用。 The Form is generated by using the PluginLoader:
该表单是通过使用PluginLoader生成的:
$formClass = Zend_Registry::get('formloader')->load('Payment');
$form = new $formClass(array('someval' => $my_arr));
Payment.php: Payment.php:
class Form_Payment extends Zend_Form
{
protected $_someval = array();
public function init()
{
$this->setAction('payment/save');
//....
$this->addElement('multiCheckbox', 'store_id', array('label' => 'Someval:', 'required' => true, 'multiOptions' => $this->getSomeval()))
}
public function setSomeval($someval) {
$this->_someval = $someval;
}
public function getSomeval() {
return $this->_someval;
}
}
As I can see the load method only returns the class name, so new $formClass();
如我所见,load方法仅返回类名,因此
new $formClass();
is equal new Form_Payment()
but why this isn't accept params? 等于
new Form_Payment()
但是为什么不接受params?
Ok I found a way by myself. 好吧,我自己找到了一条路。 I was looking for a way to inject some params while my Zend_Form was initialised.
我正在寻找一种在初始化Zend_Form时注入一些参数的方法。 It seems the only way for this is to pass the params to the constructor - which is executed before the init method.
似乎唯一的方法是将参数传递给构造函数-该构造函数在init方法之前执行。
class Form_Payment extends Zend_Form
{
private $_someval;
public function __construct(array $params = array())
{
$this->_someval = $params['someval'];
parent::__construct();
}
public function init()
{
$this->setAction('payment/save');
//....
$this->addElement('multiCheckbox', 'store_id',
array('label' => 'Someval:',
'required' => true,
'multiOptions' => $this->_someval // passed params now available
))
}
}
You can add custom function to your form class like 您可以向表单类添加自定义函数,例如
class Form_Payment extends Zend_Form
{
public function init()
{
$this->setAction('payment/save');
// and so on
}
public function doSome()
{
$this->setAction('other/action');
}
}
and call it after instanciating form in controller 并在控制器中实例化表格后调用它
$form = new $formClass();
$form->doSome();
