Codeigniter two param database breadcrumb - php

Question

I am using the php framework codeigniter.
I am attempting to create a here is an example:
animals/feline/lion
animals/feline/tiger
animals/feline/snow-leopard
animals/canine/wolf
animals/canine/coyote
Where both genus (feline) and species (lion) are both retrieved from a database and animals is a controller. I have models that place genus and species in their respective arrays. I also wish to have views for each step along the breadcrumb as follows:
animals
animals/feline
animals/canine
Any help would be greatly appreciated. I just looked at autocrumb and all it was as for displaying the breadcrumb control structure on the view, and not what I want.

Answer 1

I'd use URi routing., as another approach than __remap(), which is better, but I just wanted to give another choice
$route['animals/(:any)/(:any)'] = "animals/method/$1/$2";
In you animals controller you have
function method($genus,$species)
{
$data['breadcrumb'] = 'animals -> '.$genus.' -> '.$species.
$this->load->view('breadcrumb', $data);
$this->load->view('animals/'.$genus.'/'.$species);
}
view breadcrumb.php:
<div id="breadcrumb">
<?php echo $breadcrumb;?> <!-- Display: animals -> feline -> lion -->
</div>
View folder contains:
breadcrumb.php
animals /
feline /
feline.php
canine/
wolf.php
Is this what you were looking for?
EDIT after comments:
SO looks like we've mistaken what you wanted. If you're retrieving those variables from DB, then you could do like this:
function index()
{
$this->load->view('animals/index');
}
function genus($genus)
{
$data['genus_data'] = $this->your_model->load_genus_data($genus);
$this->load->view('animals/genus',$data);
}
function species($genus,$species)
{
$data['genus_data'] = $this->your_model->load_genus_data($genus);
$data['species_data'] = $this->your_model->load_species_data($species);
$this->load->view('animal/genusspecies',$data);
}
In your view genus.php (in folder animal):
<?php $genus_data->name;?> is an animal that...Here's a pic in its habitat.
In your view genusspecies.php (in folder animal):
<?php $species_data->name;?> is a species of genus <?php $genus_data->name;?>....
all those might be html snippets you load from database;
Your routing might look like this then:
$route['animal'] = "animal";
$route['animal/(:any)'] = "animal/genus/$1";
$route['animal/(:any)/(:any)'] = "animal/species/$1/$2";
If I were you, I'll go about this way. Do I got it better or am I still wrong somewhere?

Answer 2

Add a _remap() function to your animals controller
if($this->uri->segment(3) === FALSE)
{
$this->genus();
}
else
{
$this->species();
}
This assumes you have a method called genus() and a method called species()

Answer 3

redirect('animals/' . $genus . '/' . $species);
