验证开始日期应小于Yii中的结束日期[关闭]

My table has (among other columns) a start date and end date. I need to validate that the start date is less than the end date in Yii.

Do I validate that?

Use the CCompareValidator for comparison validation in the rules() method of your model:

array(
  'event_end_date',
  'compare',
  'compareAttribute'=>'event_start_date',
  'operator'=>'>', 
  'allowEmpty'=>false , 
  'message'=>'{attribute} must be greater than "{compareValue}".'
),
