Yii使用注意点

如果这样来SAVE的话，将会只保存两个字段，一个是加速时间，一个是队伍名称。其它的将全置空

        $team_model = new TeamInfo;
        $uid_result_info = $team_model->findByPk($uid);
        $team_model->speed_num_time = 1234566;
        $team_model->team_name = $uid_result_info['team_name'];

　　

        $criteria = new CDbCriteria;
        $criteria->addCondition( "`uid`=" . $uid );
        $criteria->addCondition( "`stage`=".$stage );
        $data =  $this->find( $criteria );

        $sql = "select id from props";
        $rows = $connection->createCommand($sql)->queryAll();

<?php $form = ActiveForm::begin( [ 'options' => [ 'enctype' => 'multipart/form-data'] ] ); ?>
