搜索不起作用并检索错误的结果

如果我只使用用户名进行搜索，但是当我使用用户名，客户和日期进行搜索时结果不会错误

public function search_count($username,$customer,$datefrom,$dateend) {
    $this->db->where('t_u_id',$username);
    $this->db->where('t_customer_id',$customer);
    $this->db->where('t_date <=',$dateend);
    $this->db->where('t_date >=',$datefrom);
    return $this->db->count_all("transactions");
}
public function search($username,$customer,$datefrom,$dateend,$limit,$start)

    $start=$start-1;

我认为你应该使用它：

    public function search_count($username,$customer,$datefrom,$dateend) {
        $this->db->select('*');
        $this->db->from('transactions');
        $this->db->where('t_u_id', $username);
        $this->db->where('t_customer_id', $customer);
        $this->db->where('t_date <=', $dateend);
        $this->db->where('t_date >=', $datefrom);
        return $this->db->get()->num_rows();
    }

因为count_all函数只返回行总数，所以它不能应用于哪里。

搜索不工作并在Codeigniter中获取错误的结果
