Step 1: Download bundle

If your project already uses Symfony Flex, execute this command to download, register and configure the bundle automatically:

composer require indragunawan/sequence-bundle

If you install without using Symfony Flex, first add the bundle by using composer then enable the bundle by adding new Indragunawan\SequenceBundle\IndragunawanSequenceBundle() to the list of registered bundles in the app/AppKernel.php file of your project

Step 2: Create your Sequence class

// src/App/Entity/Sequence.php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Indragunawan\SequenceBundle\Model\Sequence as BaseSequence;

* @ORM\Entity(repositoryClass="App\Repository\SequenceRepository")
class Sequence extends BaseSequence
    * @ORM\Id()
    * @ORM\GeneratedValue(strategy="IDENTITY")
    * @ORM\Column(type="integer")
    private $id;

    public function getId()
        return $this->id;

Step 3: Configure the bundle

# app/config/config.yml
    class: App\Entity\Sequence
    manager_name: default #if not set then the default value is 'default'

Step 4: Update your database schema

$ php bin/console doctrine:schema:update --force


Insert your sequence manually to sequence table in database

Field Data Type Required Properties Description
name string true unique Sequence name that use while you call in service manager
format string false - The format of text or string you want to be generate by service manager
last_value int false - The last value of the sequence
start_value int true - The start value for the sequence
increment_by int true - The increment of sequence value
last_reset datetime false - The date and time that sequence last restart


For format you can see table below:

Format Value Result
null 1 1
'' 2 2
{{NUMBER|3|0}} 3 003
{{ABC}} ['ABC' => 'abcVal'] abcVal
{{NUMBER|5|A}} 4 AAAA4
{{NUMBER|5|A|0}} 5 AAAA5
{{NUMBER|5|A|1}} 6 6AAAA
{{NUMBER|5|A|2}} 7 AA7AA
{{NUMBER|lower|5|A}} 8 aaaa8
{{NUMBER|ucfirst|5|abc}} 9 Abca9
{{NUMBER|upper|5|a|2}} 8 AA8AA
{{y}} - date('y')
{{m}} - date('m')
{{d}} - date('d')

Reserved Placeholder

  • NUMBER (an integer contains sequence counter).
  • php date format See this.
  • Rj, Rn, Ry, RY, Rg for Roman numeral of date format.


format value result
INV/{{NUMBER|3|0}}/{{ABC}} 1, ['ABC'=>'TEST'] INV/001/TEST
INV/{{NUMBER|3|0}} 1 INV/001

another example can be see in Tests/Utils/PlaceholderReplacerTest.php


NOTE: Sequence manager can only be use inside doctrine transaction

Call in Controller

// use Indragunawan\SequenceBundle\Services\SequenceManager
$sequenceManager = $this->get(SequenceManager::class);
$em->transactional(function () use ($entity) {

Call in Event Listener

// use Indragunawan\SequenceBundle\Services\SequenceManagerInterface
// Inject SequenceManagerInterface on constructor

public function prePersist(LifecycleEventArgs $args)
    $entity = $args->getObject();
    if ($entity instanceof EntityClass) {
        $args->getObjectManager()->transactional(function () use ($entity) {


$ php bin/console indragunawan:sequence:reset-counter sequence_name

You can put this command into Crontab for periodically restart the counter.
