How can I pass multiple variables/values through the uri?

I've been using the uri to pass multiple values to my model with something like...

Code:

<?php echo anchor("main/request_details/$r->submitTime", 'View'); ?>

and using it to make a query in the model with...

Code:

$this->db->where('submitTime', $this->uri->segment(3));

but now I need to pass 2 values through the url. Is there a way to do this or am I going about this the wrong way perhaps? Thanks

You can just add a new segment like you are when adding the 3rd.

Parameters are automatically passed to the controller/method as arguments, like
<?php echo anchor("main/request_details/$r->submitTime/anotherParameter", 'View'); ?>

You just need to capture them in the method and would be available like:

PHP Code:

function request_details($submitTime = '', $anotherParameter = '') //assign the variables being passed, AND set a default value
{
  if ( ! empty($submitTime))
  {
    //submitTime was passed, do something with it
  }
  //instead of $submitTime = $this->uri->segment(3);

  if ( ! empty($anotherParameter))
  {
    //do something with $anotherParameter
  }
  //instead of $anotherParameter = $this->uri->segment(4);
} 


By setting the default values in the method, you can use the controller for:
http://yoursite.com/main/request_details
http://yoursite.com/main/request_details/{submit_time}
http://yoursite.com/main/request_details..._parameter}

Thanks! thats exactly what I'm looking for
