我正在嘗試存儲唯一且隨機的 student_registration_id 編號。如果我當時創建了 5000 個用戶注冊，它也應該是唯一的，它應該是 10 位數字，而且我在存儲唯一 ID 的圖像下方存儲學生圖像是否完美。代碼public function store(Request $request){ $this->validate($request, [ 'student_name' => 'required|string|max:255', 'student_father_name' => 'required|string|max:255', 'student_mother_name' => 'required|string|max:255', 'student_photo' => 'required|image|mimes:jpeg,png,jpg|max:2048', ]); $input['student_photo'] = time().'.'.$request->student_photo->getClientOriginalExtension(); $folder1 = public_path('STUDENT_DATA/STUDENT_PHOTO/'); $path1 = $folder1 . $input['student_photo']; // path 1 $request->student_photo->move($folder1, $input['student_photo']); // image saved in first folder $path2 = public_path('../../../abc.com/public/STUDENT_DATA/STUDENT_PHOTO/') . $input['student_photo']; // path 2 \File::copy($path1, $path2); $input['student_name'] = strtoupper ($request['student_name']); $input['student_father_name'] = strtoupper ($request['student_father_name']); $input['student_mother_name'] = strtoupper ($request['student_mother_name']); $input['student_registration_id'] ="SIIT_".time(); Student::create($input); return back()->with('success',' STUDENT REGISTERD SUCCESSFULLY .');}

根據您的要求，以下是如何使用您的代碼實施建議的答案
public function store(Request $request)
{
$this->validate($request, [
'student_name' => 'required|string|max:255',
'student_father_name' => 'required|string|max:255',
'student_mother_name' => 'required|string|max:255',
'student_photo' => 'required|image|mimes:jpeg,png,jpg|max:2048',
]);
$input['student_photo'] = time().'.'.$request->student_photo->getClientOriginalExtension();
$folder1 = public_path('STUDENT_DATA/STUDENT_PHOTO/');
$path1 = $folder1 . $input['student_photo']; // path 1
$request->student_photo->move($folder1, $input['student_photo']); // image saved in first folder
$path2 = public_path('../../../abc.com/public/STUDENT_DATA/STUDENT_PHOTO/') . $input['student_photo']; // path 2
\File::copy($path1, $path2);
$input['student_name'] = strtoupper ($request['student_name']);
$input['student_father_name'] = strtoupper ($request['student_father_name']);
$input['student_mother_name'] = strtoupper ($request['student_mother_name']);
$id = $this->generateRegistrationId();
$input['student_registration_id'] = $id;
DB::table('locations')->insert([['center_code' => $id]])
Student::create($input);
return back()->with('success',' STUDENT REGISTERD SUCCESSFULLY .');
}
function generateRegistrationId() {
$id = 'SIIT_' . mt_rand(1000000000, 9999999999); // better than rand()
// call the same function if the id exists already
if ($this->registrationIdExists($id)) {
return $this->generateRegistrationId();
}
// otherwise, it's valid and can be used
return $id;
}
function registrationIdExists($id) {
// query the database and return a boolean
// for instance, it might look like this in Laravel
return Student::where('student_registration_id', $id)->exists();
}

您可以使用： hexdec(uniqid()); uniqid()- 返回唯一數字，但以十六進制表示，因此您必須使用： hexdec()將其轉換為十進制表示。
