在 PHP CodeIgniter 中将数组作为参数传递给模型

Question

我试图在我的Code-Igniter 应用程序中将Array as parameter 传递给Stored Procedure。当我打印该数组时，它会为我提供所选值的正确结果。但它在我的模型函数中给了我一个错误。

这是我的控制器：

public function index()
{
        $propertyType=$this->input->post('property_type');
        $area=$this->input->post('area_id');
        $clustersID['cluster']=$this->input->post('cluster_id');
        $stageId=$this->input->post('property_status');
        print_r($clustersID);
        $data['properties'] = $this->p->getPropertyByAreaCluster($propertyType, $area, $clustersID, $stageId);

            // echo "<pre>";
            // print_r($data['properties']);
            // echo "</pre>";
            // exit();
            //$data['props'] = $this->p->PropView($propId);
            $this->load->view('template/header', $data);
            $this->load->view('Property/property_view', $data);
            $this->load->view('template/footer');
    }

这是我的模型：

public function getPropertyByAreaCluster($propertyType, $area, $clustersID, $stageId)
    {
        $query = $this->db->query("call fetch_propertyType_Area_Cluster_Stage($propertyType,$area,$clustersID,$stageId)");
        if ($query) {
            $data = $query->result();
            $query->next_result(); 
            $query->free_result();
            return $data;
        }else{
            return false;
        }
    }

Answer 1

我得到了答案，只需将该数组转换为字符串并传递即可。

    public function index()
    {
        $propertyType=$this->input->post('property_type');
        $area=$this->input->post('area_id');
        $clustersID['cluster']=$this->input->post('cluster_id');
        $clusterString = implode(',', $clustersID['cluster']);

        echo "<pre>";
        // var_dump($clustersID['cluster']);
        echo $clusterString;
        echo "</pre>";
        $stageId=$this->input->post('property_status');
        print_r($clustersID);
        $data['properties'] = $this->p->getPropertyByAreaCluster($propertyType, $area, $clustersID, $stageId);

        //$data['props'] = $this->p->PropView($propId);
        $this->load->view('template/header', $data);
        $this->load->view('Property/property_view', $data);
        $this->load->view('template/footer');
   }

你可以试试这个代码：

控制器

public function fetchdata(){
$condition_array = array('category.id' => '1');
                $data = '*';
                $result_category_list = $this->common->select_data_by_condition('category', $condition_array, $data, $sortby = 'category_name', $orderby = 'ASC', $limit = '', $offset = '', $join_str = array());
}

型号

function select_data_by_condition($tablename, $condition_array = array(), $data = '*', $sortby = '', $orderby = '', $limit = '', $offset = '', $join_str = array()) {

        $this->db->select($data);
        $this->db->from($tablename);

        //if join_str array is not empty then implement the join query
        if (!empty($join_str)) {
            foreach ($join_str as $join) {
                if (!isset($join['join_type'])) {
                    $this->db->join($join['table'], $join['join_table_id'] . '=' . $join['from_table_id']);
                } else {
                    $this->db->join($join['table'], $join['join_table_id'] . '=' . $join['from_table_id'], $join['join_type']);
                }
            }
        }

        //condition array pass to where condition
        $this->db->where($condition_array);


        //Setting Limit for Paging
        if ($limit != '' && $offset == 0) {
            $this->db->limit($limit);
        } else if ($limit != '' && $offset != 0) {
            $this->db->limit($limit, $offset);
        }

        //order by query
        if ($sortby != '' && $orderby != '') {
            $this->db->order_by($sortby, $orderby);
        }

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

        //if limit is empty then returns total count
        if ($limit == '') {
            $query->num_rows();
        }
        //if limit is not empty then return result array
        log_message('debug', 'fetching data result:' . $this->db->last_query());
        return $query->result_array();
    }
