nested foreach in codeigniter view
Inside $data['process'] you need to have category ID and Inside $data['category'] also
then only you can match both ,For example the foreach loop will be like following
<?php foreach ($category as $c) { echo "<li>" . $c->CategoryName . "</li>"; foreach ($process as $r) { if($r['cat_id']==$c['id']){echo "<li><a href=\"" . base_url() . "index.php/process/id/" . $r->ProcessID . "\" target=\"_blank\">" . $r->ProcessName . "</a></li>"; } } } ?>if Both Id matches then you will print them !
Happy coding !
