Auto Number Extension for Yii 2

Yii2 extension to genarete formated autonumber. It can be used for generate document number.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist mdmsoft/yii2-autonumber "~1.0"

or add

"mdmsoft/yii2-autonumber": "~1.0"

to the require section of your composer.json file.

Usage

Prepare required table by execute yii migrate.

yii migrate --migrationPath=@mdm/autonumber/migrations

if wantn't use db migration. you can create required table manually.

CREATE TABLE auto_number (
    "group" varchar(32) NOT NULL,
    "number" int,
    optimistic_lock int,
    update_time int,
    PRIMARY KEY ("group")
);

Once the extension is installed, simply modify your ActiveRecord class:

public function behaviors()
{
    return [
        [
            'class' => 'mdm\autonumber\Behavior',
            'attribute' => 'sales_num', // required
    		'group' => $this->id_branch, // optional
    		'value' => 'SA.'.date('Y-m-d').'.?' , // format auto number. '?' will be replaced with generated number
    		'digit' => 4 // optional, default to null. 
    	],
    ];
}

// it will set value $model->sales_num as 'SA.2014-06-25.0001'

Instead of behavior, you can use this extension as validator

public function rules()
{
    return [
        [['sales_num'], 'autonumber', 'format'=>'SA.'.date('Y-m-d').'.?'],
        ...
    ];
}

New Format

Since version 1.5 we introduce new format of number. Now we use {} to evaluate as date and number of digit represented as number of ?.

public function rules()
{
    return [
        [['sales_num'], 'autonumber', 'format' => 'SA/{Y/m}/?.???'],
        ...
    ];
}

// it will set value $model->sales_num as 'SA/2019/10/0.001'


public function behaviors()
{
    return [
        [
            'class' => 'class' => 'mdm\autonumber\Behavior',
            'attribute' => 'sales_num', // required
            'value' => 'SA/{Y/m}/?.???'
        ]
    ];
}

// another usage

public function actionCreate()
{
    $model = new Sales()
    $model->load(Yii::$app->request->post());
    $model->sales_num = mdm\autonumber\AutoNumber::generate('SA/{Y/m}/?.???');
    ...
}
