Zend Framework从Zend_View_Helper调用视图助手

Question

我有一个叫做的帮助器Zend_View_Helper_FormVars,我的一个模块使用过它.我也有一个共同的帮手application/common/helpers/GeneralFunctions.php

我试图调用一个函数从Zend_View_Helper_FormVars该公司在 GeneralFunctions.php.

这是以下的简短版本Zend_View_Helper_FormVars:

class Zend_View_Helper_FormVars
{
    public $reqFieldVisual='<span class="req">*</span>';
    public $roles=array('admin'=>'admin', 'user'=>'user');
    public $paymentMethods=array('1'=>'Check', '2'=>'Credit Card',
                '3'=>'Cash', '4'=>'Other');


    public function formVars(){
        $this->baseUrl=Zend_Controller_Front::getInstance()->getBaseUrl();
        return $this;
    }

    public function mkCategoryCodeSelectGroup($codeTypeArr=array(),
        $codesArr=array()) {
        $html='';
        $html.=Zend_View_Helper_GeneralFunctions::generalFunctions()->progressMeter();
        return $html;
    }
}

这是以下代码GeneralFunctions.php:

class Zend_View_Helper_GeneralFunctions
{
    public function generalFunctions(){
        $this->baseUrl=Zend_Controller_Front::getInstance()->getBaseUrl();
        return $this;   
    }

    public function progressMeter() {
        $html='';
        $html.='<span id="progressWrapper">';
        $html.='<span id="progressMeter"></span>';
        $html.='</span>';
        $html.='';
        return $html;
    }
}

另外,忘了提一下我GeneralFunctions在这样的Bootstrap中自动加载了帮助器,它已经可用于我的所有模块了:

$view->addHelperPath(APPLICATION_PATH .'/common/helpers', 'View_Helper');

---

这是我尝试过的,但是收到错误:

// application/Bootstrap.php ----------->
function _initViewHelpers() {
    // add a helper for use for all modules
    $view->addHelperPath(APPLICATION_PATH .'/Common/Helper', 'Common_Helper');
}
//-------------------->


// application/common/helpers/General.php ----------->
class Zend_View_Helper_General extends Zend_View_Helper_Abstract
{
    public function general(){
        return $this;
    }   
    public function test(){
        return 'test 123';
    }
}
//-------------------->

// application/modules/dashboard/views/helpers/DashboardHelper.php ----------->
class Zend_View_Helper_DashboardHelper extends Common_Helper_General
{

    public function dashboardHelper(){
        return $this;
    }

    public function dashboardTest(){
        return 'from dashboard';
    }

}
//-------------------->

// application/modules/dashboard/views/scripts/index/index.phtml ----------->
echo $this->dashboardHelper()->test();
//-------------------->

我得到的错误消息:

致命错误:第2行的/Applications/MAMP/htdocs/mysite/application/modules/dashboard/views/helpers/DashboardHelper.php中找不到"Common_Helper_General"类

调用另一个View Helper实际上非常简单.

确保您的视图助手扩展Zend_View_Helper_Abstract,以便它可以访问$view.然后你可以像在视图中那样简单地调用助手,即

$this->view->generalFunctions()->progressMeter();

根据您的上述示例:

<?php

class Zend_View_Helper_FormVars extends Zend_View_Helper_Abstract {

    /* ... */

    public function mkCategoryCodeSelectGroup($codeTypeArr=array(),
        $codesArr=array()) {
        $html='';
        $html. $this->view->generalFunctions()->progressMeter();
        return $html;
    }
}
