magento-1.5 - Magento 上的选项卡配置错误

Question

我开发的 magento 扩展有一个大问题。 Localhost 一切正常，但是当我部署时，出现此错误。

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

希望能帮到你

如果您停止搜索 Google 并开始搜索您的代码，您会走得更远。

搜索异常字符串“Wrong tab configuration”

$ 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.'));

看看那个，整个源代码树中只有 两个 可能的地方可能会抛出该异常，这两个地方都在您的堆栈跟踪指示的 addTab 方法中叫。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.'));
    }

看起来您的调用正在通过第二个 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 block

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

但是，看起来它在那里找到的任何东西都不是 Mage_Adminhtml_Block_Widget_Tab_Interface 的子级。

我的猜测是因为调用 getChild 返回 false，因为您的模块没有将名称为 tab_pricematrix 的选项卡添加到布局中(您是否复制了将 XML 文件布局到新服务器？)不知道您是如何实现该模块的，因此无法确定。

祝你好运!
