The unique ID is an important part of our application. Someone like to generate application ID as auto incremental and someone like to generate their unique ID in a custom format. This post will show you how to generate a custom primary key or any field of your table with a custom ID via the Laravel ID generator package.



composer require haruncpi/laravel-id-generator


How to use it?

You can use it in your controller code like as a helper or inside your model by defining a boot method.

Example with controller

Import ID generator

use Haruncpi\LaravelIdGenerator\IdGenerator;
public function store(Request $request){

	$id = IdGenerator::generate(['table' => 'todos', 'length' => 6, 'prefix' => date('y')]);

	$todo = new Todo();
	$todo->id = $id;
	$todo->title = $request->get('title');


N.B: If you generate ID to the table id field then you must have to set the id field as fillable and public $incrementing = false; inside your model.


Example with the model

In your model add a boot method. The ID will automatically generate when a new record will be added.

public static function boot()
    self::creating(function ($model) {
        $model->uuid = IdGenerator::generate(['table' => $this->table, 'length' => 6, 'prefix' =>date('y')]);



You must pass an associative array into generate function with table, length and prefix key.

table = Your table name.

field = Optional. By default, it works on the id field. You can set other field names also.

length = Your ID length

prefix = Define your prefix. It can be a year prefix, month or any custom letter.

reset_on_prefix_change = Optional, default false. If you want to reset id from 1 on prefix change then set it true.


Example: 01

$config = [
    'table' => 'todos',
    'length' => 6,
    'prefix' => date('y')

// now use it
$id = IdGenerator::generate($config);

// use within single line code
$id = IdGenerator::generate(['table' => 'todos', 'length' => 6, 'prefix' => date('y')]);

// output: 160001


Example 02: INV-000001 for prefix string. Your field must be varchar.

$id = IdGenerator::generate(['table' => 'invoices', 'length' => 10, 'prefix' =>'INV-']);
//output: INV-000001


Example 03: YYMM000001

$id = IdGenerator::generate(['table' => 'invoices', 'length' => 10, 'prefix' =>date('ym')]);
//output: 1910000001


Example 04: By default, this package works on the ID field. You can set another field to generate an ID. Make sure your selected field must be unique and also proper data type.

$id = IdGenerator::generate(['table' => 'products','field'=>'pid', 'length' => 6, 'prefix' =>date('P')]);
//output: P00001


Example 05: By default, this package won't reset your ID when you change your prefix of ID. If you want to reset your ID from 1 on every prefix changes then pass reset_on_prefix_change => true

Reset ID yearly

$id = IdGenerator::generate(['table' => 'invoices', 'length' => 10, 'prefix' =>date('y')]);
//output: 2000000001,2000000002,2000000003
//output: 2100000001,2100000002,2100000003

Reset ID monthly

$id = IdGenerator::generate(['table' => 'invoices', 'length' => 10, 'prefix' =>date('ym')]);
//output: 1912000001,1912000002,1912000003
//output: 2001000001,2001000002,2001000003

Or any prefix change

$id = IdGenerator::generate(['table' => 'products', 'length' => 6, 'prefix' => $prefix]);
//output: A00001,A00002,B00001,B00002
