validation - Yii2 日期比较验证

Question

我有如下所示的模型规则()，但它不起作用。它总是显示错误消息。

public function rules()
{
    return [
        [['start_date','end_date'], 'date', 'format' => 'php:F d Y'],
        ['start_date','compare','compareAttribute'=>'end_date','operator'=>'<'],
        ['end_date','compare','compareAttribute'=>'start_date','operator'=>'>'],
    ];
}

Answer 1

public function rules()
{
    return [
        [['start_date','end_date'], 'date', 'format' => 'php:F d Y'],
        ['start_date','validateDates'],
    ];
}


public function validateDates(){
    if(strtotime($this->end_date) <= strtotime($this->start_date)){
        $this->addError('start_date','Please give correct Start and End dates');
        $this->addError('end_date','Please give correct Start and End dates');
    }
}

您应该编写客户端验证。 http://www.yiiframework.com/doc-2.0/guide-input-validation.html#client-side-validation
