Remove specific segment from a URL

Question

I am using codeigniter 2.xx, and this is my view code:

<a  href="users/user_info/<?=$row->user_name;?>/<?php echo $row->user_id;?>"></a>

And this is my controller code:

function user_info($name, $id)
{   
    $info['info']       =   $this->user_model->user_info($id);
    $data['content']    =   $this->load->view('home',$info,true);
    $this->load->view('template',$data);
}

When I click on the link I get this url: http://localhost/users/user_info/name/id

I want to remove last id segment so my url becomes: http://localhost/users/user_info/name. How can I do this? I read about uri segment but it doesn't solve my question.

Are you trying to read the current URL, or change an output url? — sman591, Apr 06 '13 at 05:20
just don't pass it as a reference, or us the name as an internal id? I'm not sure what you want to achieve here, please clarify your question. — Jakub, Apr 06 '13 at 05:20

If you're trying to get the current URL and remove the /id from it, simply:

$url = $_SERVER["REQUEST_URI"];

$paths = explode('/', trim(parse_url($url, PHP_URL_PATH), '/'));

unset($paths[count($paths)-1]);

$new_url = '/' . implode('/', $paths);

echo $new_url;

Which removes the last URL segment, outputting /users/user_info/name if visiting the page /users/user_info/name/id

Alternatively, you could change $url to the string in the href="...", but then again couldn't you just remove the code directly from the href?

this will do well but it will not solve because the link from href is getting name and id so how this will work.and thanks for ur ans – Azam Alvi Apr 06 '13 at 05:37
So you don't want the name to be outputted into the href="" either? – sman591 Apr 06 '13 at 05:40
sorry i can't understand what u r saying. actually i mean to say that how to use this code because i am just using `href` so if change is required then here will be done, my question is that where to use your code.thanks – Azam Alvi Apr 06 '13 at 05:43
Can you not just change `href="users/user_info/=$row->user_name;?>/user_id;?>"` to `href="users/user_info/=$row->user_name;?>"`? – sman591 Apr 06 '13 at 05:46
no i cant because i am using unique id for fetching data and for displaying in url also including name, so i can't change. – Azam Alvi Apr 06 '13 at 05:48
So you want the URL to hide the /id, but want the website to handle the request with a /id? – sman591 Apr 06 '13 at 05:50

<a  href="/users/user_info/<?=$row->user_name;?>"></a>

(At href add slash at the start) And at controller..

function user_info($name)
{   
    $info['info']       =   $this->user_model->user_info($name);
    $data['content']    =   $this->load->view('home',$info,true);
    $this->load->view('template',$data);
}

At your user Model set function user_info to catch user by username, not by user id. And you are ready..

u r right that's y i am using unique id for fetching data and for displaying purpose also using username. – Azam Alvi Apr 06 '13 at 05:44

Then there is no point to put such not unique Name at url ... Better change your idea to (id or (unique)username).. – Svetoslav Apr 06 '13 at 05:53
