I have model rules() like below, but it is not working. It is showing error message always.

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

推荐答案

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

you should write Client-Side Validation. http://www.yiiframework.com/doc-2.0/guide-input-validation.html#client-side-validation
