推荐答案

您可以使用您的模型beforeValidate servicecall

You can use your models beforeValidate servicecall for that and add extra validation criteria for this model.

例如：

function beforeValidate($options = array())
{
    if(!empty($this->data['Model']['fieldOne']))
        $this->validate['fieldTwo'] = array(/*normal validation rules*/);
    return true; // Needed or validation fails
}
