Navigation Path Problem - El Forum - 09-12-2007
[eluser]o_Ojack[/eluser]
hey guys,
im building a test result management application and i need to implement a navigation path in my header similiar to the one use in the forum:
CodeIgniter>Forum Home>CodeIgniter Development Forums>Code and Application Development.
I have only 1 controller class, 1 view for each function in the controller class and all the views use the same header file. What is the easiest way to implent that?

Does that mean you only have two levels of navigation? Effectively having a navigation path like "Controller > Method"?

Hi Zacharias,
I have more than two levels of navigation and there are 3 possible ways of navagation:
index() -> builds() -> build_testruns() -> testrun() -> test()
index() -> testruns() -> testrun_builds() -> testrun() -> test()
index() -> products() -> testrun() -> test()
The problem is all the methods are inside the same controller class, so instead of having hierachy url like http://url/controller/method/method/method, i have http://url/controller/method. That's why I am struggling.

I see the possible solution in storing these paths, or, say info about parent sections in the db, for example. But I'm not sure if it's convenient.

but the thing is all these information are dynamically generated, it really depends on what's in the database, like the available products, builds and testruns. So I don't think I would be able to store these paths into the database.

Well, unless there are some kind of systematic navigation hierachy you're probably best off using arrays (that's what I do). Like this in each controller:
Code:
$data['crumbs'][] = array('url/to/crumb', 'name');
$data['crumbs'][] = array('url/to/another/crumb', 'name');
$data['crumbs'][] = 'Final crumb'Then displaying them all like this:
Code:
foreach($crumbs as $crumb){
echo (is_array($crumb) ? '<a href="' . $crumb[0] . '">' . $crumb[1] . '</a>' : $crumb);

does it mean i have to define the full navigation hierachy path to the particular controller in each controller? say if a controller is at level 4, then i have to add an array of 3 elements in it?
what if i have something like product:codeigniter -> build: 2007-09-12 -> testrun: x -> test: y
if im now in the test controller, i know i definitely came from product->build->testrun, but how do i know which product, build and testrun i came from, since the information is dynamically generated?

Sorry, I thought you said you had only one controller. Could you explain how your application works?

It's basically structured like this:
class BTRMS extends Controller {
function __construct()
{
}
function index()
{
$this->load->view('product_view',$data);
}
function product()
{
$this->load->view('testruns',$data);
}
function builds()
{
$this->load->view('builds_view',$data);
}
function build_testruns()
{
$this->load->view('testruns',$data);
}
function testruns()
{
$this->load->view('testruns_view',$data);
}
function testrun_builds()
{
$this->load->view('testruns',$data);
}
}
so bascially this is the flow of the application:
- the index class is loaded and calls the product_view to display all distinct products, number of builds in each product, and number of testruns in each product
- the user now have two options, 1 is to see available builds for that product, or available testruns for that product. the former one calls the builds() controller from the product_view, and the latter one calls the tesetruns() controller form the product_view and the product view also passes the select product to the corresponding controller
- builds calls the testruns() calls the builds_view which shows all the builds and number of testruns in each, when user selects a build, the view will then call the build_testruns() method in the controller and pass the product and view to it
- testruns calls the builds() calls the testruns_view which shows all the testruns and number of builds in each, when user selects a testrun, the view will then call the testrun_builds() method in the controller and pass the product, and build to it
-both of the builds_testrun and testrun_builds method calls the testruns_view that shows all the testruns for select product, testrun, and build
sorry if it seems very confusing, let me know if you have you have any questions, i can send you the code if that's easier

If I understand you right, this is how I'd do it:
Code:
class BTRMS extends Controller {
function __construct()
{
$data['crumbs'] = array('url/to/home', 'Home');
$data['crumbs'] = array('url/to/products', 'Products');
$this->load->vars($data);
}
function index()
{
$this->load->view(’product_view’,$data);
}
function product()
{
$data['crumbs'] = array('url/to/product', $productname);
$this->load->view(’testruns’,$data);
}
function builds()
{
$data['crumbs'] = array('url/to/product', $productname);
$data['crumbs'] = array('url/to/build', 'product build');
$this->load->view(’builds_view’,$data);
}
function build_testruns()
{
$this->load->view(’testruns’,$data);
}
function testruns()
{
$data['crumbs'] = array('url/to/product', $productname);
$data['crumbs'] = array('url/to/testrun', 'product testrun');
$this->load->view(’testruns_view’,$data);
}
function testrun_builds()
{
$this->load->view(’testruns’,$data);
}
}
