不是在PHP与阿贾克斯

更新数据库ajax_upload_profile_image.php

<?php 
    session_start(); 
    $session_id= $_SESSION['UserId']; 

    require_once('includes/config.inc.php'); 
    if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") 
    { 
     $path = "images/profile/"; 

     $valid_formats = array("jpg", "png", "gif", "bmp","jpeg"); 

     $name = $_FILES['photoimg']['name']; 
     $size = $_FILES['photoimg']['size']; 
     if(strlen($name)) 
     { 
      list($txt, $ext) = explode(".", $name); 
      if(in_array($ext,$valid_formats)) 
      { 
       if($size<(1024*1024)) // Image size max 1 MB 
       { 
        $actual_image_name = time().$session_id.".".$ext; 
        $tmp = $_FILES['photoimg']['tmp_name']; 
        if(move_uploaded_file($tmp, $path.$actual_image_name)) 
        { 
         $query=("UPDATE users SET image='$actual_image_name' WHERE user_id='$session_id'"); 
         $result = mysql_query($query) or die(); 
         if($result) 
         { 
          echo "success"; 
         } 
         else 
         { 
          echo "fail"; 
         } 

         echo "<img src='images/profile/".$actual_image_name."' class='preview'>"; 
        } 
        else 
         echo "failed"; 
       } 
       else 
        echo "Image file size max 1 MB"; 
      } 
      else 
       echo "Invalid file format.."; 
     } 
     else 
      echo "Please select image..!"; 
     exit; 
    } 
?>

下面的代码无法正常工作。使用表单动作将数据直接发送到php脚本时更新数据库，但通过AJAX功能发送到php脚本时数据库未更新，但我收到成功消息。

默认的类型是GET在.ajaxForm插件中。

在选项中添加一个type:"POST"键。
