将变量传递给 Zend Form [英] Pass variable into Zend Form

问题描述

我有一个实例化的 Zend 表单

I have a zend form instantiated

$form = Form_Example();

现在我想将一个 ID 从我的控制器传递给我的表单.

Now I want to pass an ID from my controller to my form.

所以我这样做了:

$form = Form_Example(array('id' => $id));

在表单中我尝试通过调用它:

Inside the form I try to call it through:

$this->id

但它不在那里.

有人知道如何将那个 id 输入到表单中吗?

Anybody knows how to get that id into the form?

谢谢

推荐答案

确保你有元素的 setter，在你的例子中是 public function setId($id).Zend_Form 构造函数检查属性的setter方法是否存在，如果存在则调用它，否则它设置表单的属性，参见setAttrib($key, $value).

Make sure you have setter for the the element, in your case public function setId($id). Zend_Form constructor checks if setter method exists for the property, if it exists then it is called, otherwise it sets the attribute of the form, see setAttrib($key, $value).

最终的结果是这样的

class Application_Form_YourForm extends Zend_Form {

    /**
     * Id
     * @var <type> 
     */
    protected $_id = null;

    /**
     * Setter for ID
     * @param <type> $id 
     */
    public function setId($id){
        $this->_id = $id;
    }

    // Rest of your code...
}
