You have code at front end like this:
你在前端有这样的代码：
View
看法
<form action="{{URL::to('upload/photo')}}" class="form-horizontal" method="POST" role="form" enctype="multipart/form-data">
<input type="file" name="photo">
<button class="btn btn-default pull-right" type="submit">Create</button>
</form>
Route
路线
Route::post('upload/photo','TestController@uploadPhoto');
TestController
测试控制器
public function uploadPhoto(Request $request)
{
$this->validate($request, [
'photo' => 'mimes:jpeg,png,bmp,tiff |max:4096',
],
$messages = [
'required' => 'The :attribute field is required.',
'mimes' => 'Only jpeg, png, bmp,tiff are allowed.'
]
);
// Now save your file to the storage and file details at database.
}
I hope, you undestand.
我希望，你明白。

you can do it with validation throuhg mimes:jpegand the other types such as png etc. lookup laravel validation on the documentation page
您可以通过验证通过验证mimes:jpeg和其他类型（例如 png 等）来完成。在文档页面上查找 Laravel 验证
