Yii2: How to stop generating rand() function new value every time record gets updated?

Im using rand() function to generate booking_id in my app, its generating random string while creating the booking record. But when I update the particular record booking_id also get updated to some random string. How to stop generating random number while updating the records.

<?= Html::activeHiddenInput($model, 'booking_id', ['value' => rand('100000',10) ]) ?>

use behaviors to set the booking id e.g in this example set the booking_id with your rand value and this only for the insert event so on update the booking_id will be untouched.

Add the behaviors code to your model (or extend your existing behavior with it):

namespace app\models\base;  // or whatever your namespace is.
use yii\behaviors\AttributeBehavior; // must be added to the use part to include the correct class.
use yii\db\ActiveRecord;

class Yourclass extends ActiveRecord
{

...


   public function behaviors()
   {
    return [
        [
            'class' => AttributeBehavior::className(),
            'attributes' => [
                ActiveRecord::EVENT_BEFORE_INSERT => ['booking_id'],
            ],
            'value' => function ($event) {
                return rand('100000',10);
            },
        ],
    ];
   }

...

}

And don't use hidden field from your form. The Html Code could be modified so hidden field isn't secure to prevent user modification.
