URL / Controler realted

[eluser]exodus7[/eluser]
I don't know how to get at this, but lets say for instance, I have a url of www.mydomain.com/index.php/services/service_name/locations

I know that I would need to create a controller named "services" and a function inside the controller named "service_name", but what/how would I get the "locations" part of the URI to work?

Does that makes sense, or am missing something?

adding to the url isn't difficult. You can add all sorts of things after the method segment (service_name). In your view you can do something like following code when the url helper is loaded

Code:

<?php echo site_url('services/service_name/locations'); /* output : http://site.com/index.php/services/service_name/locations */ ?>

To retrieve that segment you have to use the segment or the rsegment (routed segment) method from the uri library

Code:

if($this->uri->segment(3) == 'locations'){ /* do something */ }

Alternatively you could say:

Code:

class Services extends Controller{
    function Services() {
        parent::Controller();
    }
        
    function service_name($location=''){
        //do something with $location
    }

You can add as many url segments as you like so long you have a corresponding function parameter.

xwero,

Thanks for the quick reply. This is making more sense - In your example,

Code:

if($this->uri->segment(3) == 'locations'){ /* do something */ }

It only checks if segment 3 = 'locations', correct?

So if I had more than one occurrence of the the same name for the 3rd URI segment, Im assuming I would have to verify the second & third segment to = specific values like so:

Code:

if($this->uri->segment(2) == 'service_name' && $this->uri->segment(3) == 'location'){ /* some code */ }

Is this correct?

[eluser]jcopling[/eluser]
You would not have to check segment(2) against anything Code Igniter is already routing the page to the appropriate controller/function.

All you would want to check would be the function parameter:

Code:

class Service extends Controller{
    function Service() {
        parent::Controller();
    }
        
    function service_name($location=''){
        switch($location){
            case 'location1':
                //do something
                break;
            case 'location2':
                //do something else
                break;
            case default:
                /* this one is especially important as you will want to know if the url segment was not passed at all */
                break;
        }
    }
}

if you have other words that are also valid you could do something like this

Code:

$thirdsegment = array('location', 'someword', 'anotherword');
$result = array_search($this->uri->segment(3),$thirdsegement);
if(is_numeric($result))
{
   // valid third section
   switch($result)
   {
     case 0: /* do something */; break;
     case 1: /* do something */; break;
     case 2: /* do something */; break;
   }
}
else
{
  // not valid third section
}

edit : the check for no third segment has to happen before you start checking for the segment value.

I want to say thanks jcopling & xwero , you've shed lots of light on this and its making more sense.

After trying jcopling's version, I'm getting an error "Parse error: syntax error, unexpected T_DEFAULT" It says the error occurred on the line that starts with "case default:"

Code:

function veterans($location='')
        {
            $data['pgtitle'] = 'Catholic Charities - Veterans Services';
            $data['crumb'] = 'services';
            $data['left_col'] = 'services';

            switch($location){
            case 'location1':
            $this->template->load('ccSecondaryPageTemplate', 'test/index1', $data);
                break;
            case 'location2':
            $this->template->load('ccSecondaryPageTemplate', 'test/index2', $data);
                break;
            case default:
            $this->template->load('ccSecondaryPageTemplate', 'services/veterans_services', $data);
                break;
        }

I'm going to try the other example and see what happens

[eluser]tonanbarbarian[/eluser]
it is just default not case default

Code:

function veterans($location='')
        {
            $data['pgtitle'] = 'Catholic Charities - Veterans Services';
            $data['crumb'] = 'services';
            $data['left_col'] = 'services';

            switch($location){
            case 'location1':
            $this->template->load('ccSecondaryPageTemplate', 'test/index1', $data);
                break;
            case 'location2':
            $this->template->load('ccSecondaryPageTemplate', 'test/index2', $data);
                break;
            default:
            $this->template->load('ccSecondaryPageTemplate', 'services/veterans_services', $data);
                break;
        }

tonanbarbarian, you are correct - it works seamlessly with no problems now - Thank you

I see xwero's example to be efficient code if there are multiple options for the third segment. Does "case 0:", "case 1:" refer to the array?

I appreciate the help all of you have given :-)

I prefer to use the uri_to_assoc function, rather than using the segment. This allows you to pass key=>value pairs and doesn't require that the variable you pass is always in the same URI segment;

http://ellislab.com/codeigniter/user-gui...s/uri.html

This allows you to use urls like;

http://site.com/index.php/services/servi...ocations/1
http://site.com/index.php/services/servi...ocations/2
http://site.com/index.php/services/servi...ocations/1

and just look for the value of locations, rather than test for every possible location.
