CodeIgniter Permalink Routing

readme

This is a bit of contrived example because it relies on our own style of page hierarchies
but perhaps this will give you a stepping stone to apply your own hierarchical page
structure.
Also this example uses DataMapper for ORM in case the model calls were confusing you.

pg.php

<?php
//would be controllers/pg.php

class pg extends Controller {
        var $pgItem;
        var $parentPage;
	function pg() {
		//do some constructor related stuff here
	}
        function permalink($segments) {
    	
    	
    	foreach($segments as $seg) {
    		//find a child of the page where permalink matches the next segment
    		
    		if ($this->pageParent == null) {	
    			$part = new Page();
    			$part = $part->get_by_permalink($seg);
    		}
    		else {
    			$part = new Page();
    			$part = $part->where('parentId', $this->pageParent->id)->where('permalink', $seg)->get();
    		}
    		if ($part->id == null) {
    			$this->e404();
    			die();
    		}
    		else {
    			unset($this->pageParent);
    			$this->pageParent = $part;
    		}
			echo $this->pageParent->permalink;
    		unset($part);
    		    	}
				
    	$this->pgItem = $this->pageParent;
    	unset($this->pageParent);
    	echo $this->pgItem->title; //at this point we have the page
    }
    function index() {
        $this->permalink(func_get_args());
	die();
    }
