获取一个公共变量了帮手为模板

Question

使用Magento的我有一类类似定义的变量：

在app /代码

/本地/ ME/MyMod /助手/ Data.php

class Me_MyMod_Helper_Data extends Mage_Core_Helper_Abstract 
{ 
    public $theVar = 'I want this'; 
} 

然后在app/design/frontend/Me/some.phtml中查看如何获取这个变量？

Mage::helper('MyMod')->iDontKnowWhatIamDoing; 

Answer 1

你可以这样做：

class Me_MyMod_Helper_Data extends Mage_Core_Helper_Abstract 
{ 
    public $theVar = 'I want this'; 

    public function send_to_template() { 
     return $this->theVar; 
    } 
} 

而且在模板：

Mage::helper('MyMod')->send_to_template(); 

Answer 2

下面写功能Data.php

class Me_MyMod_Helper_Data extends Mage_Core_Helper_Abstract 
{ 
    public function getThis() 
    { 
    $theVar = 'I want this'; 
    return $theVar; 
    } 
} 

使用下面的代码

打电话给你的变量

echo Mage::helper('MyMod')->getThis();
