3 个解决方案

#1

Two things to change:

两件事改变:

Change your js file from:

将你的js文件从:

 data:{
    logo:new FormData($("#upload_form")[0]),
 },

To:

 data:new FormData($("#upload_form")[0]),

Because you would like to send the whole form.

因为你想把整个表格寄出去。

In your html:

html:

Add a name to your file input field

将名称添加到文件输入字段中

<input type="file" class="form-control" id="catagry_logo">

To:

<input type="file" name="logo" class="form-control" id="catagry_logo">

#2

it doesn't work for me because of dataType:'json'. If anyone gets error just remove dataType:'json'.

由于数据类型为“json”，我无法使用它。如果有人出错，就删除dataType:'json'。

#3

Check in your controller what you get when you post:

检查你的控制器当你发布:

echo dd(Input::all());

Check files object in php. This in PHP:

在php中检查文件对象。这在PHP中:

$_FILES

Request::file("logo");

Yeah, you're not really posting any data? Is the form really posting?

是的，你并没有发布任何数据?这张表真的贴出来了吗?
