Use uri segment in Codeigniter - php

Question

I want to pass a variable from view to controller, from html to php, I tried searching in search engines how to do that in Codeigniter, and I found that I need to use uri segment. I don't know how to do this. I donMt understand where and how I can use uri.
I want pass variable $id via link
<div class="content-primary">
<ol data-role="listview" data-filter="true" data-inset="true">
<?php if(isset($record)) :
foreach ($record as $row) :?>
<li> <?php echo $row->username;?></li>
<?php endforeach; ?>
<?php else : ?>
<h2> No activiti </h2>
<?php endif;?>
</ol>
</div><!--/content-primary -->
</div>
I want to pass $id to my controller

Answer 1

You want to change the 3d line of code from this:
<li><a href="<?php echo base_url()?>link?$id"> <?php echo $row->username;?>
to this:
<li><a href="<?php echo base_url()."YOUR_CONTROLER/YOUR_FUNCTION/".$id; ?> <?php echo $row->username; ?>
That will result in a link like:
http://yourwebsite.com/YOUR_CONTROLER/YOUR_FUNCTION/ID
And in your controller, you can access and use "ID" in the "YOUR_FUNCTION" method.

Answer 2

in my view i add link
<li><a href="<?php echo base_url()?>link/show_id/mantap"> coba </li>
in my link.php controler i add function show_id
function show_id(){
$id=$this->uri->segment(3);
$data['coba'] = $id;
$this->mobile->view('**daftarmember_form**',$data);
in my next view daftarmember_form.html
)
<?php echo $id;?>
they print mantap,
