URI Routing, best way to do that

[eluser]daweb[/eluser]
I everybody,

I have to read from a DB some records and I have to build my dynamic query based on uri segments. (and some $_POST values...)

I have, for example:

http://www.my-site.com/buy

http://www.my-site.com/sell

http://www.my-site.com/buy/car

http://www.my-site.com/sell/motocycle/red

http://www.my-site.com/buy/dog/big/italy...g-name/123

I want to build the query in just one controller...

Is it the right way to make: ?

$route['buy/(:any)/(:any)/(:any)/(:any)/(:any)'] = 'home/$5';
$route['sell/(:any)/(:any)/(:any)/(:any)/(:any)'] = 'home/$5';

$route['buy/(:any)/(:any)/(:any)/(:any)'] = 'home/$4';
$route['sell/(:any)/(:any)/(:any)/(:any)'] = 'home/$4';

$route['buy/(:any)/(:any)/(:any)'] = 'home/$3';
$route['sell/(:any)/(:any)/(:any)'] = 'home/$3';

$route['buy/(:any)/(:any)'] = 'home/$2';
$route['sell/(:any)/(:any)'] = 'home/$2';

$route['buy/(:any)'] = 'home/$1';
$route['sell/(:any)'] = 'home/$1';

$route['buy'] = 'home';
$route['sell'] = 'home';

What's the best solution to make this?

I'm very sorry about my english...

Will be better tomorrow... :-)

I think you don't have to do any routing for this. You just check how many segments there are and take action based on that data

Code:

function buy()
{
   if($this->uri->total_segments() > 1)
   {
      $segments = $this->uri->segment_array();
      array_shift($segments);
      // do something with the segments
   }
   else
   {
      // default page
   }
}

function sell()
{
   // see buy
}

thank you xwero,

just a question...

if buy and sell are dynamic too, can I use your code in my default controller?

is the right way?

PS. This quesions 'cause I'm using Ocular library first time, and... it's difficoult for me.

Thank you so much...

If buy and sell are dynamic too you could do something like

Code:

function home()
{
   $segments = $this->uri->segment_array();
   $first =  array_shift($segments);
   switch($first)
   {
      case 'buy':
         if(count($segments) == 0)
         {
             // default buy page
         }
         else
         {
            // do something with the segments
         }
         break;
      case 'sell':
         // see buy
         break;
      default:
         // error or default page
         break;
   }
}
