我试图在代码输入if语句时显示一个字符串.

我仔细检查过,代码确实进入了声明,但没有打印出来.

这是我的控制器功能:

public function clock_in()
{

    $this->load->model('model_users');


       $this->db->where('USER_EMAIL', $this->session->userdata('USER_EMAIL'));

    $query = $this->db->get('clocked_in_users');

    if($query->num_rows() == 1){



         echo "Already Clocked in";
        exit;

    }else{

    $this->model_users->clock_user_in();
    };



    redirect('main/members');




}

和我的观点:

    
Members






    ";
        print_r ($this->session->all_userdata()); //displays all user session data.
        echo "

"; $this->load->helper('date'); echo "

"; echo $date = date('Y-m-d H:i:s'); echo "

"; ?> Clock In

Clock Out
