How to pass the value from view to controller

Question

here my controller code

$data['query']= $this->webpages->get_where_custom('parent_id',0); 
// i  will get $id from view 
$data['query']=$this->webpages->get_where_custom('parent_id',$id);

$this->load->view-(template,$data);

   <?php

   foreach($query->result() as $row){
       $id=$row->id;   // how to send this $id to my controller
       $page_url=$row->page_url;
       $parent_id=$row->parent_id;
       $page_headline=$row->page_headline;

  foreach($query->result() as $row){
       $page_url=$row->page_url;
       $page_headline=$row->page_headline;

  ?>
  echo $page headline;
  }

}

Answer 1

Insted of:

$this->load->view-(template,$data);

Try:

$this->load->view(template,$data);

Answer 2

your code look like this

$this->load->view('template',$data);

and it is because your didn't put $id in the data you put query

so <?php print_r($query); ?> <?php print_r($query); ?>
