YII implementation model Add a default value method (2 methods) _php instance

The example of this article describes the method of adding the default value of YII implementation model. Share to everyone for your reference, specific as follows:

Yii model inherits from Cactiverecord

Some fields may not appear in the form, but need to be added to the program . such as order number, time stamp, Operation user_id and so on.

Here are two ways to:

1, in the Rules () method set:

Public function rules ()
{
  //note:you should only define the rules for those attributes that
  //would receive user Inputs.
  Return Array (
    ' Start, end ', ' required '),
    array (' user_id ', ' numerical ', ' integeronly ' =>true),
    Array (' timestamp ', ' Default ', ' Value ' =>date (' y-m-d h:i:s ')),
    //The following rule are used by search ().
    Please remove the those attributes that should is searched.
    Array (' ID, start, end, user_id, timestamp ', ' safe ', ' on ' => ' search ')
  ;
}

2, in the BeforeSave () method set:

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

It should be noted that theBeforeSave () method requires return true, otherwise it will not be saved .

I hope this article will help you with the PHP program design based on the YII framework.
