Yiii method to add default values to yii model (2 methods)

This article describes the method of adding default values to Yii's model. Share it for your reference, as follows:

yii model inherits from CActiveRecord

Some fields may not appear in the form and need to be added to the program.. Such as order number, timestamp, user_id of operation, etc.

The following two methods:

1. Set in the rules() method:

public function rules()
{
  // NOTE: you should only define rules for those attributes that
  // will receive user inputs.
  return array(
    array('start, end', 'required'),
    array('user_id', 'numerical', 'integerOnly'=>true),
    array('timestamp','default','value'=>date('Y-m-d H:i:s')),
    // The following rule is used by search().
    // Please remove those attributes that should not be searched.
    array('id, start, end, user_id, timestamp', 'safe', 'on'=>'search'),
  );
}

2. Set in the beforeSave() method:

function beforeSave()
{
  $this->user_id = Yii::app()->user->id;
  return true;
}

It should be noted thatbeforeSave() method needs return true, otherwise it will not be saved。

I hope that this article will be helpful to everyone's PHP programming based on the Yii framework.
