Laravel Sequence

Generate sequential numbers with pattern (e.g. for invoice numbers)

Features

  • Easy integration
  • Multiple pattern placeholders
  • Support for three most common reset frequencies
  • Automatically creating new ordinal number based on reset frequency

Installation

composer require nextgen-tech/laravel-sequence

Usage

use Carbon\Carbon;
use NGT\Laravel\Sequence\Enums\ResetFrequency;
use NGT\Laravel\Sequence\Models\SequenceRule;
use NGT\Laravel\Sequence\SequenceFactory;

/**
 * Create new sequence rule. It needs to be done only once.
 */
SequenceRule::create([
    'type'            => 'invoice',
    'pattern'         => '{number}/COMPANY/{year}',
    'reset_frequency' => ResetFrequency::YEARLY,
]);

/**
 * Make sequence factory via container or DI.
 */
$factory = app(SequenceFactory::class);

/**
 * Create sequence by passing sequence type and date (e.g. issue date of invoice).
 */
$sequence = $factory->create(
    'invoice',
    Carbon::createFromFormat('Y-m-d', '2021-06-01')
);

/**
 * Public methods of sequence.
 */
$ordinal = $sequence->getOrdinalNumber(); // e.g. 21
$number  = $sequence->getNumber();        // e.g. 21/COMPANY/2021
$pattern = $sequence->getPattern();       // e.g. {number}/COMPANY/{year}

/**
 * After use of generated number, manual increment of ordinal number is required.
 */
$sequence->increment();

Reset Frequencies

Sequences supports three most commonly used reset frequencies. \NGT\Laravel\Sequence\Enums\ResetFrequency class should be used when creating new sequence rule.

  • ResetFrequency::YEARLY - resets ordinal number at the beginning of new year
  • ResetFrequency::MONTHLY - resets ordinal number at the beginning of new month
  • ResetFrequency::DAILY - resets ordinal number at the beginning of new day

Pattern Placeholders

Placeholder Description Example
{number} generated, ordinal number
{day} day of passed date with leading zero 05
{month} month of passed date with leading zero 03
{year} full year of passed date 2021
{day_short} day of passed date without leading zero 5
{month_short} month of passed date without leading zero 3
{year_short} short year of passed date 21
