mage的语法错误:: getstoreconfig

Question

仔细按照处理交叉卖出的答案（如何增加购物车中的Crosssell项目数量？）一切似乎都效果很好......添加：

的最终说明

保护$ _maxitemcount= mage :: getstoreconfig（'mycompany_section / mycompany_group / mycompany_field'）;

因此产生错误：

p>解析错误：语法错误，意外'（'，期待'，'或';'中的/public_html/app/code/local/xxx/checkout/block/cart/crosssell.php

对此Magento / PHP新手的任何帮助将非常感谢:)

magento ver。1.9.2.1

编辑：

使用Crosssell.php使用@simonthesorcerer修正案如下：

Answer 1

您正在声明一个类属性，但是在执行此操作时，您无法调用函数。

相反，更改如下所示的声明：

protected $_myPropertyName;

.

我假设您的块扩展MAGE_CORE_BLOCK_ABSTRACT。然后，您应该覆盖函数_construct（）并填写属性：

protected function _construct() { 
$this->_myPropertyName = Mage::getStoreConfig('configname');
return parent::_construct(); }

.

抱歉格式化，我在手机上。
