我有一些困难,从HTML表单上传图像。表单应该能够将图像名称与其他数据一起发送到php页面。使用formData插入图像到数据库与ajax
我使用formData而不是序列化函数,因为它无法处理文件数据。
$(document).on('click', '#btn_add', function(){
var formData = new FormData($(this)[0]);
$.ajax({
url:"includes/widgets/insert.php",
type: 'POST',
data: formData,
async: false,
cache: false,
contentType: false,
processData: false
success: function (data) {
alert(data);
},
});
return false;
});
HTML表单
<form id="insert_post" action="includes/widgets/insert.php" method="post" enctype="multipart/form-data" >
<div class="row">
<div class="medium-6 columns">
<label>First name
<input type="text" name="first_name" id="first_name" contenteditable>
</label>
</div>
<div class="medium-6 columns">
<label>Last name
<input type="text" name="last_name" id="last_name" contenteditable>
</label>
</div>
<div class="medium-12 columns">
<label>Last name
<input type="file" name="file" id="image" multiple contenteditable>
</label>
</div>
</div>
<button type="button" name="btn_add" id="btn_add" class="button btn btn-xs btn-success" >Submit</button>
</form>
php page
<?php
$connect = mysqli_connect("localhost", "root", "", "myaddboard");
echo $_POST['first_name'];
echo $_POST['last_name'];
echo $image = $_FILES['file']['name'];
echo $image_tmp = $_FILES['file']['tmp_name'];
/*
if(empty($image)){
echo 'error';
}
move_uploaded_file($image_tmp,"img/$image");
//$sql = "INSERT INTO posts(post_content, post_author) VALUES('".$_POST["first_name"]."', '".$_POST["last_name"]."')";
if(mysqli_query($connect, $sql))
{
echo 'Data Inserted';
} else {
echo 'error';
}
*/
?>
PHP的形式只是为了测试是否正确AJAX发送数据。
当我按一下按钮我总是得到的PHP变量没有被定义
我一次比一次我提交表单的错误错误
undefined index: frist_name in c:xampp\htdocs\unv\includes\widgets\insert.php on line 4
undefined index: last_name in c:xampp\htdocs\unv\includes\widgets\insert.php on line 5
undefined index: file in c:xampp\htdocs\unv\includes\widgets\insert.php on line 8
undefined index: file in c:xampp\htdocs\unv\includes\widgets\insert.php on line 9
我应该怎么做才能让阿贾克斯发送数据到php页面?
