从DB编辑多个图像

Question

我试图从数据库编辑图像记录。数据提取部分没问题，但我的编辑代码无效。我使用插入部分修改此代码。插入到数据库正在工作，但编辑不起作用。我是php的新手。我想为我的分类广告项目添加包含表单数据的多个图像。

在编辑页面上......

<input type="file" name="upload[]" onchange="previewFiles()" multiple />

在编辑处理页面....

<?php                       

  $file_dir  = "../images/";

    mkdir($file_dir, 0777, true);
  }

    function diverse_array($array) { 
      $result = []; 
      foreach($array as $key1 => $value1) 
        foreach($value1 as $key2 => $value2) 
          $result[$key2][$key1] = $value2; 

      return $result; 
    }

    $file_multi  = diverse_array($_FILES['upload']);

    for ($y = 0; $y < 4; $y++) {    
      $image[$y] = '';
    }
