php – 来自Zend_View_Helper的Zend Framework调用视图助手

我有一个叫做Zend_View_Helper_FormVars的助手,我的一个模块使用过它.
我在application / common / helpers / GeneralFunctions.PHP中也有一个共同的帮助器

我正在尝试从GeneralFunctions.PHP中的Zend_View_Helper_FormVars调用一个函数.

这是Zend_View_Helper_FormVars的简短版本：

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GeneralFunctions.PHP中的代码：

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,忘了提一下我在这样的Bootstrap中自动加载了GeneralFunctions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();
//-------------------->

我收到错误消息：

Fatal error: Class ‘Common_Helper_General’ not found in /Applications/MAMP/htdocs/mysite/application/modules/dashboard/views/helpers/DashboardHelper.PHP on line 2

调用另一个View Helper实际上非常简单.

确保您的视图助手扩展了Zend_View_Helper_Abstract,以便它可以访问$view.那么你可以像在视图中那样简单地给助手打电话,即

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

根据您上面的示例：

<?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;
    }
}
