php+html5使用FormData对象提交表单及上传图片的方法,

本文实例讲述了php+html5使用FormData对象提交表单及上传图片的方法。分享给大家供大家参考。具体分析如下:

FormData 对象,可以把form中所有表单元素的name与value组成一个queryString,提交到后台。在使用Ajax提交时,使用FormData对象可以减少拼接queryString的工作量。

使用FormData对象

1.创建一个FormData空对象,然后使用append方法添加key/value

复制代码 代码如下:

var formdata = new FormData(); 
formdata.append('name','fdipzone'); 
formdata.append('gender','male');

2.取得form对象,作为参数传入到FormData对象

复制代码 代码如下:

 
 
 

复制代码 代码如下:

var form = document.getElementById('form1'); 
var formdata = new FormData(form);

使用FormData提交表单及上传文件:

复制代码 代码如下:

name:

 
       

gender:male female

 
       

photo:

 
       

 
   
 
   
 
  

server.php如下:

复制代码 代码如下:

$name = isset($_POST['name'])? $_POST['name'] : ''; 
$gender = isset($_POST['gender'])? $_POST['gender'] : ''; 
$filename = time().substr($_FILES['photo']['name'], strrpos($_FILES['photo']['name'],'.')); 
$response = array(); 
if(move_uploaded_file($_FILES['photo']['tmp_name'], $filename)){ 
    $response['isSuccess'] = true; 
    $response['name'] = $name; 
    $response['gender'] = $gender; 
    $response['photo'] = $filename; 
}else{ 
    $response['isSuccess'] = false; 

echo json_encode($response); 
?>

运行效果如下图所示:
