How to create custom ID Generator in Laravel 8

In this video, we will show you how to make custom id generator in laravel 8. The ID generator takes a unique external ID in the form of a string and returns a unique ID, which can be used as an item ID (for example, TLS006, STD-0005, INV_5750). You can use this example in order to make your own custom id. You can use this when you want to make Invoices, appointments, students , etc IDs.

Thank you so much. This video helped me to resolve one of my ID Generating issues.

[@jamalbayacine3829]

I think you have to note these instructions :
if($last_number_length>$length){$og_length=0;}
else{$og_length=$length-$last_number_length;}
thank you for this video.

[@irebelibrary]

Hi Elie Bea. you can use my package: github.com/mbere250/laravel-idify for creating custom ID. That package will do the same to this.

Since it is capturing max ID What happens if two users are trying to insert new student simultaneously????

[@naufalnadaandesa7799]

I have an error its "Attempt to read property "no" on null". "no" is like the number id of document and the error was in this line : $code=(substr($data->$trow, strlen($prefix)+1));
how to solve this sir, thanks before

[@voskilltheentertainer2564]

this tutorial saved me.how can i pass the custom id generated to an api endpoint?

[@Alerodb2020]

In laravel 9 with PHP 8.1.2 it shows this error “Unsupported operand types: string / int” when saving for the first time.
change the line
$code = substr($data->$trow, strlen($prefix)+1);
to
$code = (int)(substr($data->$trow, strlen($prefix)+1));
With that it works for me, thank you very much for the idea of the IDGenerator.

[@irebelibrary]

Hello alexander.
I hadn't tried it in laravel 9.
Thank you so much for the correction

Hi Irebe, thank you so much for your video, can you please tell me and how to fix this error,
ErrorException
Required parameter $prefix follows optional parameter $length
I use same your code in helper class.

[@irebelibrary]

make sure that this helper function has all parameters
public static function IDGenerator($model, $trow, $length = 4, $prefix){}
also in controller:
$student_id = Helper::IDGenerator(new Student, 'student_id', 2, 'STD'); /** Generate id */

[@alanali7177]

@@irebelibrary Thank you so much for your support, much appreciated.
I checked, but I have same error, This my code:
in contoller:
function insertDoctor(Request $request){
$request->validate([
'name'=>'required',
]);
$name = $request->name;
$email = $request->email;
$phone = $request->phone;
$address = $request->address;

$save = $q->save();
if($save){
return back()->with('success','New studen has been added');
}else{
return back()->with('faile','Something went wrong');
}
}
And I use custom helper class and I import:
use App\mi\mi;
inside ( mi ) class, I use same your code without edit it.
public static function IDGenerator($model, $trow, $length = 4, $prefix){}
And also make a route:
Route::post('insertdoctor',[AdminController::class,'insertDoctor'])->name('admin.insertDoctor'); and call that route in form:
action="{{ route('admin.insertDoctor') }}"
And I import also model class:
use App\Models\doctors;
this is code in model class
class doctors extends Model
{
use HasFactory;
protected $primaryKey = 'id';
protected $fillable = [
'doctor_id',
'name',
'email',

@Stephen Awuor 1) student_id (s) must be lower case on this line:
$Student_id = Helper::IDGenerator(new Students, 'Student_id', 4, 'STD');
to $Student_id = Helper::IDGenerator(new Students, 'student_id', 4, 'STD');
2) make sure that you import this on this controller:
use App\Helpers\Helper;
use App\Models\Student;
use Validator;
3) Watch how you can create custom helper:
