Laravel Sequence

This is a fork for Laravel 11 of the original package nextgen-tech/laravel-sequence with a few minor tweaks / enhancements.

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
• Laravel 11 support

Installation

composer require nextgen-tech/laravel-sequence

Usage

use Carbon\Carbon;
use Guava\Sequence\Enums\ResetFrequency;
use Guava\Sequence\Models\SequenceRule;
use Guava\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. \Guava\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	4
{number:<x>}	generated, ordinal number, padded to the given length. Replace <x> by the desired length	0004
{day}, {DD}	day of passed date with leading zero	05
{month}, {MM}	month of passed date with leading zero	03
{year}, {YYYY}	full year of passed date	2021
{day_short}, {D}	day of passed date without leading zero	5
{month_short}, {M}	month of passed date without leading zero	3
{year_short}, {YY}	short year of passed date	21
