Zend框架工作自定义视图助手错误

Question

您好我想在我的应用程序中添加自定义助手

已完成以下步骤

1. 的index.php

   $view = new Zend_View();
   $view->addHelperPath('My/View/Helper', 'My_View_Helper');
   Zend_Controller_Action_HelperBroker::addHelper($viewRenderer);
   

2. My/View/Helper中的助手类

   class My_View_Helper_Common extends Zend_View_Helper_Abstract
   {
   
       public function example()
       {
         return "ok"; 
       }
   }
   

3. 现在调用视图index.phtml

   $this->example()
   

我收到这个错误

Uncaught exception 'Zend_View_Exception' with message 'script 'error/error.phtml' not found in path (.\application\views\scripts\)' in C:\xampp\htdocs\wyfixture\library\Zend\View\Abstract.php:924

#5 C:\xampp\htdocs\wyfixture\library\Zend\Controller\Action.php(523):

请帮我

除了Vikas的答案.

要在视图助手中调用多个方法,可以使用如下代码:

在 My/View/Helper/Example.php

class My_View_Helper_Example extends Zend_View_Helper_Abstract
{
    public function example()
    {
        return $this;
    }

    public function foo()
    {
        return 'foo';
    }

    public function bar()
    {
        return 'bar';
    }

    public function __toString()
    {
        return $this->foo();
    }
}

在你看来:

echo $this->example()->foo() // prints foo
echo $this->example()->bar() // prints bar
echo $this->example() // prints foo
