限制文件大小和文件类型
如何限制控制器上的文件大小和文件类型？我尝试了不同的方法，但不应该起作用。
这是我的控制器：
public function add_presentation_detail(Request $request){
$start_date = $request->start_date;
$input_file = $request->file;
$nik = Sentinel::getUser()->nik;
$data = AccelerateMentee::select(
'accelerate_mentee.*',
'accelerate_rotation.start_date',
'accelerate_rotation.id as id_rotation'
)
->leftJoin('accelerate_rotation', 'accelerate_rotation.id_mentee', '=', 'accelerate_mentee.id')
->where([
['accelerate_mentee.nik', '=', $nik],
['accelerate_rotation.status', '<>', 'approved']
])
->first();
if (!empty($request->file) && $request->hasFile('file')) {
$filename = $input_file->getClientOriginalName();
$new_filename = "presentation_" . "-" . $filename;
$upload_file = $input_file->storeAs('public/accelerate/',$new_filename);
} else {
$new_filename = null;
}
$update = AccelerateRotation::where('id', '=', $data->id_rotation)
->update([
'status' => 'submitted',
'panel_time_start' => $start_date,
'file' => $new_filename,
]);
return redirect()->back();
谢谢你，我现在很困惑。
how can I limit the file size and file type on my Controller? I'm tried different ways but shouldn't work.
This is my Controller :
public function add_presentation_detail(Request $request){
$start_date = $request->start_date;
$input_file = $request->file;
$nik = Sentinel::getUser()->nik;
$data = AccelerateMentee::select(
'accelerate_mentee.*',
'accelerate_rotation.start_date',
'accelerate_rotation.id as id_rotation'
)
->leftJoin('accelerate_rotation', 'accelerate_rotation.id_mentee', '=', 'accelerate_mentee.id')
->where([
['accelerate_mentee.nik', '=', $nik],
['accelerate_rotation.status', '<>', 'approved']
])
->first();
if (!empty($request->file) && $request->hasFile('file')) {
$filename = $input_file->getClientOriginalName();
$new_filename = "presentation_" . "-" . $filename;
$upload_file = $input_file->storeAs('public/accelerate/',$new_filename);
} else {
$new_filename = null;
}
$update = AccelerateRotation::where('id', '=', $data->id_rotation)
->update([
'status' => 'submitted',
'panel_time_start' => $start_date,
'file' => $new_filename,
]);
return redirect()->back();
Thank you, I'm so confused right now.

您永远不应该使用来自用户输入的输入数据。你不能信任用户。这就是为什么你应该使用 Laravel 验证。 在这里您可以阅读有关它的更多信息。在使用文件存储之前，您应该验证用户输入。如果一切顺利，那么您应该继续并使用经过验证的输入。
然后你使用这个经过验证的数据
You should never use the input data from the user's input. You can not trust the user. That's why you should use Laravel Validation. Here you can read more about it. Before you use your file store, you should validate user input. If everything goes well then you should proceed and use this validated inputs.
Then you use this validated data
