我将如何格式化Zend_Form_Element_Radio，以便标签位于输入之后

Question

I have been trying to implement the solution in an earlier version of this question at:

How would I format Zend_Form_Element_Radio so the label follows the input?

By creating an extended helper MyLib_View_Helper_FormRadio but must be missing something obvious with this!

My question is how do I get Zend_Form_Element_Radio() to use this now instead of the version of the helper in Zend_View_Helper_FormRadio ?

I thought initially that this was done by creating the element with

$radio = new MyLib_View_Helper_FormRadio();

but realised its not.

Changing the way the label and input are ordered in the Zend_View_Helper_FormRadio.php does the trick but I realise that the Zend files should not be altered.

If anyone can help me with t his I would be very grateful!

Answer 1

In your MyLib_View_Helper_FormRadio class, you have a method, like this (it's an example):

public function formRadioCustom($name, $value = null, $attribs = null,
    $options = null, $listsep = "<br />\n"){...}

So to call it instead of formRadio of Zend_View_Helper_FormRadio , if I'm not mistaken, you have to do:

 $element->addDecorators(array(array('ViewHelper',array('helper' => 'formRadioCustom'))));

And in your bootstrap add a method to add helper like this:

protected function _initViewHelpers() {
    $view = new Zend_View();
    $view->->addHelperPath('MyLib/View/Helper/', 'MyLib_View_Helper');
}
