Question

这是我的控制器

serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>

这是我的模特

function search_keyword()
{
    $cari    =   $this->input->GET('cari');
    $data['dapat']    =   $this->order_test_m->search($cari);
    $this->load->view('admin/a',$data);
}

这是我的观点

    function search($cari)
    {
        $this->db->from("uhd_user_order AS t1");
        $this->db->join("uhd_user_product_order AS t2", "t1.user_order_id = t2.user_order_id");
        $this->db->where('user_order_reference',$cari);
        $query = $this->db->get('uhd_user_order');
        return $query->result();
    }

我需要帮助的人我是codeigniter的新手。我需要进行搜索，但搜索结果需要我的数据库中的2个表。

                    <tr>
                        <th>No.</th>
                        <th>Customer Name</th>
                        <th>Product Code</th>
                        <th>Payment Type</th>
                        <th>Delivery Date</th>
                        <th>Total Price</th>
                        <th style="text-align: center;padding-right: 15px;">Action</th>
                    </tr>
            <?php if($dapat !== NULL) { ?>
                <?php foreach ($dapat as $row => $test) {

                    ?>
                    <tr>
                        <td><?= $test->user_order_id?></td>
                        <td><?= $test->sender_name?></td>
                        <td><?= $test->user_product_order_id?></td>
                        <td><?= $test->payment_type ?></td>
                        <td><?= $test->time.$test->date ?></td>
                        <td><?= $test->delivery_price?></td>
                    </tr>
                <?php }
            }else{
                echo "<td colspan='3'>no customer for the result!</td>";

            }
            ?>
        </table>

，time和date来自user_product_order_id，uhd_user_product_order，user_order_id，sender_name和{{1} （此搜索键）来自payment_type

在视图中我可以从我的表uhd_user_order查看它，但我无法查看user_order_reference，uhd_user_order和time

你能帮助我如何加入2表，这样我就能从搜索中看到最好的结果

Answer 1

在您的模型上使用此代码

public function search($cari){

      $this->db->select('*');
      $this->db->from("uhd_user_order AS t1");
      $this->db->join("uhd_user_product_order AS t2", "t2.user_order_id = t1.user_order_id");  # confirm user_order_id in both table
      $this->db->where('user_order_reference',$cari);
      $query = $this->db->get();
      return $query->result();
}

Answer 2

function search($cari)
{
    $this->db->from("uhd_user_order AS t1");
    $this->db->join("uhd_user_product_order AS t2", "t1.user_order_id = t2.user_order_id");
    $this->db->where('user_order_reference',$cari);
    $query = $this->db->get('uhd_user_order');
    return $query->result();
}

成为

    function search($cari)
    {
        $this->db->join("uhd_user_product_order" , "uhd_user_order.user_order_id = uhd_user_product_order.user_order_id");
        $this->db->where('user_order_reference',$cari);
        $query = $this->db->get('uhd_user_order');
        return $query->result();
    }

使用连接表进行codeigniter搜索
