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。自从我把它移到实时安装（PHP5 / MySQL）后，我什么都没有问题！我修复了任何全局变量问题（引导我学习PDO所以不是坏事！）而不打开全局变量，所以我唯一的问题是文件上传。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？

以下是表单数据：

     <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：）

Answer 1

如果php.ini设置为file_uploads，您是否可以检查On。

; Whether to allow HTTP file uploads.
; http://ph .net/file-uplollow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On

Answer 2

请参阅php.ini config。

;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Whether to allow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
; http://php.net/upload-tmp-dir
upload_tmp_dir = "...../tmp"

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 128M

memory_limit中的max_execution_time和php.ini配置参数可能也很有用。更多：Handling file Uploads -> Common Pitfalls

确保文件夹"../Uploads/"存在，并且有权在apache / nginx work（www_data或其他类似工具）下为用户编写

这可能是问题吗？另外一个'（本节中的括号：

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))

文件上传适用于PHP4但不适用于PHP5
