php - 当我尝试在 magento adminhtml 中运行 sql 查询时，它会提供数据，但是我在其他地方遇到了 magento 错误

Question

这是我的代码位于 app\design\adminhtml\default\default\template\customer\tab\addresses.phtml

    $arrParams = $this->getRequest()->getParams();
    $read = Mage::getSingleton('core/resource')->getConnection('core_read');
    $query = 'SELECT entity_id, parent_id, is_active FROM ' .    Mage::getSingleton('core/resource')->getTableName('customer_address_entity').'
    WHERE parent_id = '.$arrParams['id'];
    $results1 = $read->fetchAll($query);

数据是正确的，但是当我尝试在后端创建新客户时出现错误

(SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1)

Answer 1

$arrParams['id'] 是问题所在。它在其他位置为空。

谢谢
