Answer 1

  

使用此$ this-＆gt; input-＆gt; get（）

   public function viewpatient()
    {

    $data['id'] = $this->input->get('id');
    echo $data['id'];

   }

Answer 2

在您的视图

<td>
    <a href="<?php echo site_url("Customer/viewpatient/" . $id); ?>" ><button type="button" name="admit" class="btn btn-danger" data-toggle="modal" id="btnViewCust">Admit</button>
    </a>
</td>

控制器功能

public function viewpatient($id = 0)
{

    echo $id;

}

您在get请求中发送值并在帖子中捕获。并以这种方式更改您的链接。
