Magento上的选项卡配置错误

Question

我开发的magento扩展有一个很大的问题.Localhost一切都很好但是当我部署时,它会收到此错误.

选项卡配置错误

我用Google搜索了几个小时但找不到任何有用的信息.我的magento版本是1.5.0.1

希望你能帮忙

如果您停止搜索Google并开始搜索代码,您将获得更多.

搜索异常字符串"错误的选项卡配置"

$ ack 'Wrong tab configuration'
Adminhtml/Block/Widget/Tabs.php
108:                throw new Exception(Mage::helper('adminhtml')->__('Wrong tab configuration.'));
112:            throw new Exception(Mage::helper('adminhtml')->__('Wrong tab configuration.'));

看一下,整个源代码树中只有两个可能抛出异常的地方,两者都在addTab你的堆栈跟踪指示的方法中被调用.在上下文中查看该代码

public function addTab($tabId, $tab)
{
    if (is_array($tab)) {
        $this->_tabs[$tabId] = new Varien_Object($tab);
    }
    elseif ($tab instanceof Varien_Object) {
        $this->_tabs[$tabId] = $tab;
        if (!$this->_tabs[$tabId]->hasTabId()) {
            $this->_tabs[$tabId]->setTabId($tabId);
        }
    }
    elseif (is_string($tab)) {
        if (strpos($tab, '/')) {
            $this->_tabs[$tabId] = $this->getLayout()->createBlock($tab);
        }
        elseif ($this->getChild($tab)) {
            $this->_tabs[$tabId] = $this->getChild($tab);
        }
        else {
            $this->_tabs[$tabId] = null;
        }

        if (!($this->_tabs[$tabId] instanceof Mage_Adminhtml_Block_Widget_Tab_Interface)) {
            throw new Exception(Mage::helper('adminhtml')->__('Wrong tab configuration.'));
        }
    }
    else {
        throw new Exception(Mage::helper('adminhtml')->__('Wrong tab configuration.'));
    }

看起来您的呼叫正在通过第二个if/else分支运行.您的选项卡字符串tab_pricematrix用于从当前选项卡中获取子块

$this->_tabs[$tabId] = $this->getChild($tab);

然而,它看起来像什么发现那里是不是一个孩子Mage_Adminhtml_Block_Widget_Tab_Interface.

我的猜测是因为调用getChild返回false,因为你的模块没有添加一个带有tab_pricematrix布局名称的选项卡(你是否将Layout XML文件复制到新服务器？)不知道你是如何实现该模块的,这是不可能肯定的.

祝好运!
