我有一个具有两种不同类型输入的表单。一个是type ='file'，另一个是type ='text'。 现在，我试图通过在jquery中使用formdata（）将这些输入发送到数据库，但是无论如何我都无法发送两个输入。
<form class='form-group' id='first_banner_form' enctype='multipart/form-data'>
<label class='btn btn-warning btn-block textbutton'>
upload your image<input type='file' class='hidden'
name='banner_number_one' id='banner_number_one'/>
</label>
<br>
<input type='text' class='form-control' name='banner_number_one_addr' id='banner_number_one_addr'
placeholder='write your name' style='text-align:center'/>
<hr>
</form>
<br>
<hr>
<br>
<button class='btn btn-success btn-block textbutton' id='upload_a_banner'>Upload</button>
这是我的jQuery代码
$(document).on('click','#upload_a_banner',function(){
var banner_form = new FormData($('#first_banner_form')[0]);
$.ajax({
url:'phpScript/upload_new_banners.php',
method:'POST',
data:banner_form,
async: false,
cache: false,
contentType: false,
processData: false,
success:function(data)
{
if(data=='done')
{
alert('uploaded');
}elseif(data=='file is not set')
{ alert('database couldn\'t recieve all data');
}
else{
alert(data);
}
},error:function()
{
alert('error');
}
});
});
这是php代码
if(isset($_FILES['banner_number_one']) && isset($_FILES['banner_number_one_addr']))
{
# the image
$fr_banner_name = $_FILES['banner_number_one']['name'];
$fr_banner_temp = $_FILES['banner_number_one']['tmp_name'];
#the link
$fr_link = $_FILES['banner_number_one_addr']['name'];
}else{
echo 'file is not set';
exit;
}
我刚写
if(isset($_FILES['banner_number_one']))
一切正常，但是当我写
if(isset($_FILES['banner_number_one']) && isset($_FILES['banner_number_one_addr']))
我收到“文件未设置”消息。我该怎么办？

数组中：
banner_number_one_addr
答案 1 :(得分：1)
banner_number_one_addr是$ _POST的一部分，因此请使用isset($_POST['banner_number_one_addr'])而不是isset($_FILE['banner_number_one_addr'])
if(isset($_FILES['banner_number_one']) && isset($_POST['banner_number_one_addr'])){
...
}
答案 2 :(得分：1)
这是因为banner_number_one_addr位于$ _POST数组中：
$ _ POST ['banner_number_one_addr']
