Question

我需要为视图生成url链接，并将数据库中的数据显示到此视图中。我的主要观点是艺术家/歌手，它有一个歌手表。每个歌手应该是一个链接，当我按下时会带我到他的艺术家页面，带有他的专辑，传记和歌曲。

我需要在Code Igniter中执行此操作，当然我可以阅读文档，但需要一周左右的时间，我只有2天。

这是我的代码：

    $this->load->database();

    $artists = $this->db->query('SELECT a.name, a.date, c.name FROM artist as a, country as c WHERE a.country_id=c.id'); 

    echo "<tr><td>Artist</td><td>Year</td><td>Country</td></tr>";

    foreach ($artists->result() as $row)
    {
        //echo $config['base_url'];
        echo "<tr>";
        echo "<td><a href=\"/Artist.php\">" . $row->name . "</a></td>";
        echo "<td>" . $row->date . "</td>";
        echo "<td>" . $row->name . "</td>";
        echo "</tr>";
    }
    echo "</table>";

Answer 1

找到表艺术家的主键，用于expample id或artist_id并添加到查询

$artists = $this->db->query('SELECT a.artist_id,a.name, a.date, c.name FROM artist as a, country as c WHERE a.country_id=c.id');

并在您的代码中

foreach ($artists->result() as $row)
{
    //echo $config['base_url'];
    echo "<tr>";
    echo "<td><a href=\"/Artist.php?aid=" . $row->artist_id . "\">" . $row->name . "</a></td>";
    echo "<td>" . $row->date . "</td>";
    echo "<td>" . $row->name . "</td>";
    echo "</tr>";
}
echo "</table>";

并在控制器艺术家通过$ _GET ['aid']

获取数据

Answer 2

我认为你需要创建一个像

这样的路线

$route['artist/(:any)'] = "controller/load_artist_page/$1";

并在你的href标签中

base_url('artist/'.$parameter);

并在函数中获取id并加载该视图，

function load_artist_page($artist_id){
//do processing and load view.
}

在传递之前加密id。

Answer 3

我会做这样的事情

$autoload['libraries'] = array('database');
$autoload['helper'] = array('url');

模型

Example_model.php

<?php

class Example_model extends CI_Model {

public function getArtist() {
    $artists = $this->db->query('SELECT a.artist_id,a.name, a.date, c.name FROM artist as a, country as c WHERE a.country_id=c.id'); 
    return $artists->result();
}

}

控制器示例

<?php

class Example extends CI_Controller {

  public function __construct() {
     parent::__construct();
     $this->load->model('example_model');
  }

  public function index() {
     $data['artist'] = $this->example_model->getArtist();

     $this->load->view('example_view', $data);
  }

}

然后在视图

<?php foreach($artist as $row) {?>
<tr>
<td><?php echo anchor('artist/' . $row->artist_id,  $row->name, array('target' => '_blank'));?></td>";
<td>$row->date</td>
<td>$row->name</td>
</tr>
<?php }?>

然后在路线上

$route['artist/(:any)'] = "controller/function/$1";

在Codeigniter中创建视图的URL
