php - 文件上传适用于 PHP4 但不适用于 PHP5

Question

我有一个在本地安装 (PHP4/MySQL) 中设计的应用程序，它运行良好。自从我将它移至实时安装 (PHP5/MySQL) 以来，除了问题我什么都没有!我修复了所有全局变量问题(引导我学习 PDO，这不是一件坏事!)，但没有打开全局变量，所以我遇到的唯一问题是文件上传。我尝试了 $_file 的 isset 测试，看起来变量从未设置过？有任何想法吗？

这是表单数据:

     <form enctype="multipart/form-data" method="post" action="script_add_product.php" >   

     <input class="cp_forms_upload" type="file" name="full_image" />

     <input class="cp_formsButton" type="submit" name="submit_button" value="Add Product" /></form>

这是 PHP:

    $full_image_url = $_FILES["full_image"]["name"];     

    if ((($_FILES["full_image"]["type"] == "image/gif")
    || ($_FILES["full_image"]["type"] == "image/jpeg")
    || ($_FILES["full_image"]["type"] == "image/pjpeg")
    || ($_FILES["full_image"]["type"] == "image/png"))
    && ($_FILES["full_image"]["size"] < 400000))
      {
     if ($_FILES["full_image"]["error"] > 0)
      {
       echo "Return Code: " . $_FILES["full_image"]["error"] . "<br />";
       }
     else
       {
      echo "Upload: " . $_FILES["full_image"]["name"] . "<br />";
      echo "Type: " . $_FILES["full_image"]["type"] . "<br />";
      echo "Size: " . ($_FILES["full_image"]["size"] / 1024) . " Kb<br />";
      echo "Temp file: " . $_FILES["full_image"]["tmp_name"] . "<br />"; 

      if (file_exists("../Uploads/" . $_FILES["full_image"]["name"]))
       {
         echo $_FILES["full_image"]["name"] . " already exists. ";
        } 
      else 
         {
         move_uploaded_file($_FILES["full_image"]["tmp_name"],
         "../Uploads/" . $_FILES["full_image"]["name"]);
         echo "Stored in: " . "../Uploads/" . $_FILES["full_image"]["name"];
     echo "<br /><br /><br />" . $full_image_url;
         }
       }

      }

      else
      {
     echo "Invalid file";
       }

谢谢大家:)

如果 file_uploads 设置为 On，请检查您的 php.ini。

; Whether to allow HTTP file uploads.
