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

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

代码如下:

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：

 

代码如下:

name:

gender:male female

photo:

server.php is as follows:

The code is as follows:

$name = isset($_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);
?>
