My View :-
<html>
<?= link_tag(base_url().'css/simple.css'); ?>
<body>
<?php $this->load->helper('form'); ?>
<?php $this->load->view('commentform'); ?>
<?php $id=$this->uri->segment(3);?>
<?php echo $id;?>
</body>
</html>
i would like to use the variable $id in my controller.I’m using codeigniter by the way, and am a beginner. I would appreciate any help on this.
Well, ideally you wouldn’t do it this way. You should assign the variable first in the controller and pass it to the view if you need to use it there.
$id would then be available in your view as well.
