Question

我建立了一个计算复数的报告，并且使用了ajax。该代码可在我的本地主机上完美运行，但在服务器上会抛出500条内部错误，而没有任何消息。我尝试在每个代码块之后使用dd，而这正是引发错误的那部分

$decoded_needs = [];
  foreach ($needs_teacher as $needs) {
    $decoded_needs[] = json_decode($needs->training_needed);
  }
  if (empty($decoded_needs)) {
    $training_needs_teacher = array(['0' => 'None']);
  } else {
    $sanitized_needs = [];
    foreach ($decoded_needs as $key => $items) {
      foreach ($items as $index => $item) {
        foreach ($item as $name => $bit) {
          $sanitized_needs[$name][] = $bit;
        }
      }
    }

$s_standards = [];
$s_sub_category = [];

// dd() works here

foreach ($sanitized_needs['standard'] as $skey => $standard) {
  $sname = DB::table('lesson_observation_teacher_standards')->where('id', $standard)->first()->name;
  $s_standards[] = $sname;
    foreach ($sanitized_needs['sub_category'] as $key => $substandard) {
      $name = DB::table('lesson_observation_teacher_standard_categories')->where('id', $substandard)->first()->name;
       if ($key == $skey) {
         $s_sub_category[$sname][] = $name;
       }
    }
}
// but not here 
$training_needs_teacher = [];
foreach ($s_sub_category as $key => $index) {
  foreach ($index as $items) {
    $training_needs_teacher[$key] = array_count_values($index);
  }
}

$sanitized_needs = [];
foreach ($training_needs_teacher as $key => $items) {
  foreach ($items as $index => $item) {
    $sanitized_needs[$key . ":" . count($items)][] = $index . ":" . $item;
  }
}
$training_needs_teacher = $sanitized_needs;
}

我知道我可以在许多情况下使用WhereIn，但我需要重复的物品。我只想知道是否有解决此问题的方法？请注意，我的ajax包含csrf令牌。

我认为问题在于通往数据库的路径

我已经解决了这个问题，您必须对路径进行三重检查，在您的本地环境中，您的站点可能位于根路径，因此DB ::可以正常工作，但在生产中，您应该在数据库引用之前放置一些内容，例如\ rootFolder \ DB ：：
