Hi I made a little improvement to the helper request builded in “Alternative to GET” and made a way to put multiples variables in a same GET segment. The url notation would be like this
www.yoursite.com/index.php/class/function/value1/variable2:value2::variable3:value3::variableN:valueN

As yo see I used “::” to spread variables in the same uri segment, it even works to put a non predictable count of elements; i used it for example with the pagination library. This is the code of the new Request helper:

<?php if ( ! defined(‘BASEPATH’)) exit(‘No direct script access allowed’); 
/***
* request_helper.php by EliuX(eliux.softwares@gmail.com)
**/
//Receive an array like key:value
  function getRequests($requests)
{
  //get the default object
  $CI =& get_instance();
  //declare an array of request and add basic page info
  $requestArray = array();
  if($requests==array(”“))  //If there is nothing specified, finish it!
    return $requests;
  foreach ($requests as $request)
  {
      if(strrpos($request, ‘:’) >0)
      {
        list($key,$value)=explode(’:’, $request);
        if(!empty($value) || $value=’‘) $requestArray[$key]=$value;
      }else{
        $requestArray[]=”$request”;
      }
  }
  return $requestArray;
}

  function multiRequests($params)
  {
    //get de root object
    $CI =  & get_instance();
    $duplesArray =  array();
    if(strrpos($params, ‘::’) > 0)      //If there is the variables separator, the spread it!
    {
      $duplesArray = explode(’::’,$params);
      return getRequests($duplesArray);  //Each dupla will be spread too! 
    }else{  //Si no hay mas de una variable
      return getRequests(array($params));
    }
  }

?>

You have to call the funcion multiRequests and in its param the variable of the controller function you know has the multiples variables “:” separated. This is an example:

<?
//Test controller

class Test extends Controller
{
  function Test()
  {
    parent::Controller();
    $this->load->helper(“request”);   
  }
 
  //Testing the multiRequests function
  function testing($var1,$variables)
  {
  //I take the multiples variables specified in this controller variable segment
  $params = multiRequests($variables);
  echo “The variable 1 is $var1”;
  foreach($params as $param=>$value)
    echo “<br>Variable $param is “.$value;
  }

}

So an url like http://localhost/test/testing/value1/variable2:value2::variable3:value3::variable4:value4 will print:

The variable 1 is value1
Variable variable2 is value2
Variable variable3 is value3
Variable variable4 is value4

An request like http://localhost/cubel/test/testing/value1/variable2:value2 will print:

The variable 1 is value1
Variable variable2 is value2

and an url like http://localhost/cubel/test/testing/value1/variable2 will print:

The variable 1 is value1
Variable 0 is variable2

Look how at this final example it formated the sole variable in a simple array with initial index in 0.

I hope you’ll find it usefull.
