【问题描述】:
我在从 html 表单上传图片时遇到了一些困难。表单应该能够将图像名称与其他数据一起发送到 php 页面。
我使用 formData 代替序列化函数,因为它不能处理文件数据。
$(document).on('click', '#btn_add', function(){
var formData = new FormData($(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表单只是为了测试ajax是否正确发送数据。
当我单击按钮时,我总是收到未定义 php 变量的错误
我每次提交表单时遇到的错误
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ajax将数据发送到php页面?
