Question

我们的团队购买了Blanco theme，对Magento来说是个不错的主题。然后在安装后我尝试进入产品详细信息页面并收到此错误：

Fatal error: Cannot redeclare themeOptions() (previously declared in
C:\wamp\www\magento\app\design\frontend\default\blanco\template\page\html\head.phtml:6) in
C:\wamp\www\magento\app\design\frontend\default\blanco\template\page\html\head.phtml on line 113

首先，我查看了提供商网站，以阅读常见问题解答和任何可能的问题。没有运气，所以我在那里发布了我的问题。无论如何我不能等他们回答...我搜索了这个错误，并在StackOverflow，this post，this other one和其他一些地方找到了一些建议。但是那里给出的答案没有用，或者我可能没有正确实施。尝试使用function_exist，但它阻止加载该功能，并且产品详细信息页面上根本没有加载主题。 include_once "head.html";都不起作用。

我确认该函数未在代码中的任何其他位置声明。

你建议我做什么？是一个phtml文件，所以它里面有php和html标签的组合。这是代码：

Answer 1

本文为解决这个问题提供了良好的开端。我确实评论了雅罗斯拉夫的建议，但它并没有为我解决问题。然后我使用function_exists结构似乎有用。它必须用于head.phtml中的2个函数

1）function themeOptions（$ themeOption）

2）函数jsString（$ str =''）

在function_exits中包含上述函数

if(!function_exists(themeOptions)){
function themeOptions ($themeOption) {
    //Piece of Code
    }
    }

if(!function_exists(jsString)){
    function jsString($str='') {
//Piece of Code
}
}

在此之后，一切似乎都运转正常。

Answer 2

由于这个模块的编码方式错误（不应该在模板中声明php函数，而是在BLock中声明！）2解决问题的方法：

查看您的布局，了解为什么此模板包含两次。这是正常的（您试图在两个不同的位置显示此模板吗？如果是这样的话：您需要转到解决方案＃2，因为无法重新声明PHP函数）
修改模块以使用“magento way”（MVC）进行工作：在专用块中移动函数声明（在模块的BLock文件夹中）。如果需要，在模块的config.xml中声明BLock层，并在模块的布局XML文件中链接模板和Block。

告诉模板创建者尊重magento标准;）

Answer 3

最后，Magento的全新安装再次出现错误。在仔细检查了exception.log文件和发现错误的特定phtml文件后，我设法通过注释一行并添加一小段代码来使其工作。

这是来自exception.log文件的错误：

异常'Exception'，消息'Notice：Undefined variable：tab 在 C：\ WAMP \ WWW \ Magento的\ APP \设计\前台\ DEFAULT \布兰科\模板\目录\产品\图\ tabs.phtml 在8'线上 C：\瓦帕\ WWW \ Magento的\应用\代码\核心\法师\核心\的functions.php：245

这是tab.phtml文件中的有罪行：

<?php if ($tab != $this->getChildHtml('product_custom_tab')): $last = 'last'; endif; ?>

我所做的就是评论它并添加一个新行：

<?php //if ($tab != $this->getChildHtml('product_custom_tab')): $last = 'last'; endif; ?>
<?php $last = 'last'; ?>

现在一切似乎都很顺利，我现在正在检查它，产品详细信息显示，所有花哨的翻转工作，标签也可以。
