所以我想加入3张桌子.

我正在构建一个app i Codeigniter,我有3个表

客户:
-id
-phone_number
-hospital_id
-smc_status
-testing_center_id

医院
-id
-name

Testing_center
-id
-name

在模型中,我有这个:

public function get_clients()
    {
        if($slug === FALSE)
        {
            $this->db->select('clients.*');
            $this->db->from('clients');
            $this->db->join('hospital', 'clients.id = hospital.id');
            $this->db->join('testing_center', 'clients.id = testing_center.id');
            $query = $this->db->get();

            return $query->result_array();
        }

        $query = $this->db->get_where('clients');
        return $query->row_array();
    }

在视图中我有:

<tbody>
    <?php foreach ($clients as $client_item): ?>
    <tr>
        <td><?php echo $client_item['phone_number'] ?></td>
        <td><?php echo $client_item['smc_status'] ?></td>
        <td><?php echo $client_item['hospital_id'] ?></td> //i wish to have the hospital name here
        <td><?php echo $client_item['testing_center_id'] ?></td> …
