php - Codeigniter 中特定列字段搜索的实现

Question

过去几周我的代码中一直存在错误，我尝试了各种方法但无法使其工作，我正在尝试在 codeigniter 中实现特定的列字段搜索功能。这是我的场景，用户登陆年龄，并决定按姓名、成员关系和位置搜索人员列表。这是我的 Controller 、模型和 View ......

型号:

function get_advanced($address2,$partners,$typeofirm){
            echo $address2,$partners,$typeofirm;
            $query = "SELECT firm_id,address2,partners,typeofirm FROM auditfirms WHERE address2 LIKE '%$address2%' OR partners LIKE '%$partners%' OR typeofirm LIKE '%$typeofirm%' ORDER BY 'firm_id' LIMIT 10";
            // return print_r(json_encode($query->result_array()));
            $adv =  $this->db->query($query)->result_array();
            if ($query->num_rows() > 0){
                $row = $query->row_array();             
                echo $query;
                var_dump($adv); die();
                return $adv;
            }
            else{
                echo 'Error at syntax';
            }

Controller

function advanced(){
            $this->load->library('pagination');
            $config['base_url'] = 'http://localhost/icpak/index.php/firms/search';
            $config['total_rows'] = $this->db->get('auditfirms')->num_rows();
            $query1 = $config['per_page'] = 10;
            $query2 = $config['uri_segment'] = 3;
            $config['num_links'] = 5;
            $config['full_tag_open'] = '';
            $config['full_tag_close'] = '';
            $config['cur_tag_open'] = '<span class="current_page">';
            $config['cur_tag_close'] = '</span>';
            $config['anchor_class'] = 'class="btn btn-default" ';               
            $this->pagination->initialize($config);         
            $address2 = $this->input->post('address2');
            $partners = $this->input->post('partners');
            $typeofirm = $this->input->post('typeofirm');

            $data['advanced'] = $this->firms_model->get_advanced($address2,$partners,$typeofirm);
            $this->load->view('index/advanced', $data);
        }

View :是一个模态窗口，窗体位于...

您的 $query 有问题。请参阅代码中的注释。

function get_advanced($address2,$partners,$typeofirm){
            echo $address2,$partners,$typeofirm;
            $query = "SELECT firm_id,address2,partners,typeofirm FROM auditfirms WHERE address2 LIKE '%$address2%' OR partners LIKE '%$partners%' OR typeofirm LIKE '%$typeofirm%' ORDER BY 'firm_id' LIMIT 10";
            // return print_r(json_encode($query->result_array()));
            $adv =  $this->db->query($query)->result_array(); 
           //  $query is string.. so at this point you must get error.
           // if ($query->num_rows() > 0){
              if (count($adv) > 0){
                // $row variable is unused. but it will give you first record.
                $row = $adv[0];         
                return $adv;
            }
            else{
                echo 'Error at syntax';
            }
 }
