在Cakephp验证中，FromDate应该小于ToDate

Question

我想比较有效日期应该小于生效日期。我的演示代码是..

 public function addValidations()
        {
            parent::addValidations();
            $this->validate['EffectiveToDate'] = array
            (
                'notempty' => array
                (
                    'rule'    => array('comparison', 'greater or equal', 'EffectiveFromDate'),
                    'allowEmpty' => false,
                    'message' => 'Effective From Date Greater Than To Date.',
                ),
            );
        }

所以，请建议我适当的解决方案。

尝试此代码，看看它是否对您有所帮助。

public $validate = array(
    'datecompare' => array(
        'rule'    => 'dateCompare',
        'message' => 'Effective From Date Greater Than To Date.'
    )
);

public function dateCompare($check) {
    $datetocheck = strtotime('16/03/2014');
    $today  = strtotime(date('dd/mm/yyyy'));
    if($datetocheck >= $today)
    {
        return true;
    }
}

干杯！
