如何从codeigniter中的URL获取id？ [英] How to get id from URL in codeigniter?

问题描述

我想从网址获取id，以删除该特定的选定产品。我已经使用 $ this-> uri-> segment（3），但它没有从URL获取任何值。

如果我使用 $ this-> url-> segment（2） / code>它给我的第二个值形式URL，但我无法获得产品Id。
下面是我的代码。请指导我。

VIEW

  echo< a href ='delete_controller？product_id = $ product_id'>; 
 echo $ name; 
 echo< / a>; 
  

点击$ name时会生成以下URL。

  http：//localhost/designs2/index.php/products_controller/delete_controller？product_id = 70 
  

控制器

  public function delete_controller 
 {
 echo $ product_id = $ this-> uri-> segment（3）; 
 echoTaha; 
 $ this-> load-> view（'delete_confirmation'）; 
} 
  

解决方案

值应该像这样输入url

  localhost / yoururl / index.php / products_controller / delete_controller / 70 
  
 
 
 
并且在控制器函数中你可以这样读取
  function delete_controller（$ product_id = NULL）{
 echo $ product_id; 
} 
  
 
I am trying to get 'id' from URL in order to delete that specific selected product. I have used $this->uri->segment(3) but its not getting any value from URL. Although i can see the 'product_id' in my URL.

If i used $this->url->segment(2) it gives me the second value form URL, but i am unable to get product Id.
Following is my code. Kindly guide me.

VIEW
echo "<a href='delete_controller?product_id=$product_id'>";
echo $name;
echo "</a>";
The following URL is generating when i click on $name.
http://localhost/designs2/index.php/products_controller/delete_controller?product_id=70
Controller
public function delete_controller()
    {
        echo $product_id =$this->uri->segment(3);           
        echo "Taha";
        $this->load->view('delete_confirmation');
    }

解决方案
if you have to pass the value you should enter url like this 
localhost/yoururl/index.php/products_controller/delete_controller/70
and in controller function you can read like this
function delete_controller( $product_id = NULL ) {
  echo $product_id;
}
