我的网上商店在安装新主题后破了，但是在将主题更改回默认值后错误仍然存​​在。

我不知道是什么导致这个，我在管理面板中安装主题后遇到的另一个错误，如果我点击“类别”我会收到此错误：

非常感谢任何帮助。

永远不要假设存在变量。如果提供商没有提供正确的值，情况可能会发生变化。

由于缓存，您可能很幸运，之前没有弹出错误。

在menutop，你有85号线

if($categoryArr[0]['active_product']== 1)

这些是您的代码所做的假设：

  • 变量$ categoryArr是一个数组。
  • 变量$ categoryArr至少有一个索引为0的条目
  • 变量$ categoryArr [0]是一个关联数组
  • 变量$ categoryArr [0]的索引为'active_product'

这是很多假设。

为了使其更具防弹性，理想情况下，您可以使用辅助函数来访问具有故障保护默认值的数组，或使用复杂的if语句

if(!is_null($categoryArr) && is_array($categoryArr) && array_key_exists(0,$categoryArr) && !is_null($categoryArr[0]) && is_array($categoryArr[0]) && array_key_exist('active_product', $categoryArr[0]) ){

或您使用辅助功能

function getValue($key, $arr, $default=null) {
   $pieces = explode('.', $key);
   $array = $arr;

   foreach($pieces as $array_key) {

      if(!is_null($array) && is_array($array) && array_key_exists($array_key, $array)) { 
          $array = $array[$array_key];
      }
      else {
          $array = null;
          break;
      }
   }
   return is_null($array) ? $default : $array;
}

$testarr = [
    ['foobar' => 'baz'],
    ['active' => false]
];
$output = getValue('0.foobar',$testarr,'NOT FOUND');
var_dump($output);
$output = getValue('0',$testarr,'NOT FOUND');
var_dump($output);
$output = getValue('1.active',$testarr,'NOT FOUND');
var_dump($output);
$output = getValue('i.do.not.exist',$testarr,'NOT FOUND');
var_dump($output);
