php - nested foreach in codeigniter view -

-

i have 4 tables: process, country, process_country , category. each process belongs category. country may have several processes available , process may available in several countries. below database structure:

category table       process table        country table      process_country --------------       --------------       -------------      --------------- categoryid           processid            countryid          countryid categoryname         processname          countryname        processid                      categoryid                      countryid

i have created functions available processes each country wanted display processes under corresponding categories dont know how implement. able list processes , categories separately don't know how nest them. achieve page list each country:

>  1. category 1 >        process 1 >        process 2 >  2. category 2 >        process 3

i thinking nested foreach loop:

<?php         foreach ($category $c) {             echo "<li>" . $c->categoryname . "</li>";             foreach ($process $r) {                 echo "<li><a href=\"" . base_url() . "index.php/process/id/" . $r->processid . "\" target=\"_blank\">" . $r->processname . "</a></li>";             }         }     ?>

but not know how implement foreach loop processes under category.

controller:

$data['process'] = $this->getprocesses(); //function gets process available country $data['category'] = $this->getcategories(); //function gets categories $this->load->view('includes/template', $data);

inside $data['process'] need have category id , inside $data['category']

then can match both ,for example foreach loop following 

<?php         foreach ($category $c) {             echo "<li>" . $c->categoryname . "</li>";             foreach ($process $r) {                 if($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 print them !

happy coding !
