在php codeigniter中通過url傳遞一個id

Question

我想通過url傳遞頁面id這裏是我的代碼，問題是我不會獲得所需的頁面id到頁面只獲取路徑。請幫忙。 查看頁面

<li> 
<a href="view/page_id=$page_id"><i class="fa fa-table fa-fw"></i>Hotel 1</a>   
</li> 
<li> 
<a href="view1/page_id=$page_id"><i class="fa fa-table fa-fw"></i>Hotel 2</a>        
</li> 

控制器Page

public function view() 
{ 
echo $page_id =$this->uri->segment(1); 
$this->load->helper('url'); 
$data['offers_name'] = $this->Login_set->get_offer($id); 
$data['offers_description'] = $data['offers_name']['offers_description']; 
$this->load->view('App_stay/pages/hotel1_offers.php'); 
} 
public function view1() 
{ 
echo $page_id =$this->uri->segment(2); 
$this->load->helper('url'); 
$data['offers_name'] = $this->Login_set->get_offer($id); 
$data['offers_description'] = $data['offers_name']['offers_description']; 
$this->load->view('App_stay/pages/hotel2_offers.php'); 
} 

Answer 1

更改此：

<li> 
<a href="view/page_id=$page_id"><i class="fa fa-table fa-fw"></i>Hotel 1</a>   
</li> 
<li> 
<a href="view1/page_id=$page_id"><i class="fa fa-table fa-fw"></i>Hotel 2</a>        
</li> 

成這樣：

<li> 
<a href="view/<?php echo $page_id ?>"><i class="fa fa-table fa-fw"></i>Hotel 1</a>   
</li> 
<li> 
<a href="view1/<?php echo $page_id ?>"><i class="fa fa-table fa-fw"></i>Hotel 2</a>        
</li> 

在控制器中添加$this->uri->segment('segment_number')擺脫網址

public function view() 
{ 
    $page_id =$this->uri->segment(3); 

    $data['offers_name'] = $this->Login_set->get_offer($id); 
    $data['offers_description'] = $data['offers_name']['offers_description']; 
    $this->load->view('App_stay/pages/hotel1_offers.php'); 
//I put your codes here because you want Spoon Feed 
} 
    public function view1() 
    { 
     $page_id =$this->uri->segment(3); 
     ...//rest of your codes here 
    } 

Answer 2

您可以通過爲URL參數

<li> 
<a href="view/$page_id"><i class="fa fa-table fa-fw"></i>Hotel 1</a>   
</li> 

，並且可以訪問像這樣的控制器

public function view($page_id) 
{ 
    echo $page_id; 
} 

可以在控制器構造負荷幫手

function __construct() { 
    $this->load->helper('url'); 
}
