I want to be able to filter a paginated list based on passed params.
eg filter buy Area, category ..etc

http://dev.mydomain.co.uk/property
if i go directly to the page i do not get an error.

class EstateCategoryPage_Controller extends Page_Controller {
static $allowed_actions = array(
      'show','EstateItemList'
   );

//do i need a routes.yml file
public static $url_handlers = array(
    'property//$Action/$ID/$EstateCategoryPageID' => 'EstateItemList'
    );

function EstateItemList() {
   
   $Area = '%';
   $OfferStatus = 'FOR SALE';
   $ECatPageID = 30;
   
      
   /* test for retrival of QueryString
   $CatPageID = Controller::curr()->getRequest()->param('EstateCategoryPageID');
   //$CatPageID = $this->request->param('EstateCategoryPageID');
   //print query string
   //print_r($CatPageID); //yeap it works
   */
   
    $buildfilter = EstateItem::get()->filter(array('Area:PartialMatch'=> $Area,'Active' => 1,'OfferStatus' => $OfferStatus));
   
    //fixes the page in pagination
    $PaginatedList = new PaginatedList($buildfilter,$this->request);
    $PaginatedList->setPageLength(2);
    $PaginatedList->setLimitItems(1);
    return $PaginatedList;   
   
}

//comment i'm not actually doing any filtering yet from the passed params..baby steps!

....
}//end controller


If i go to the page and call a function to pass query string i get an error
http://dev.mydomain.co.uk/property//action/params/params/

eg: http://dev.mydomain.co.uk/property//EstateItemList/29/Offices/

error : The method 'getviewer' does not exist on 'PaginatedList'

i've looked at this ticket also
http://www.silverstripe.org/data-model-questions/show/11817

and tried

return $this->customise($PaginatedList)->renderWith('PropertyResults');

error : The method 'getviewer' does not exist on 'DataList'

return $this->customise($buildfilter)->renderWith('PropertyResults');

error : The method 'getviewer' does not exist on 'DataList'

// Please do not change the exception code number below.
660          
661          throw new Exception("Object->__call(): the method '$method' does not exist on '$this->class'", 2175);

You're trying to render a list directly using /EstateItemList/ in the browser which rather than returning an HTML template you've got it returning a List.

You should name your action and method *differently* or render the list into some template instead of returning it.

static $allowed_actions = array(
'show','list'
);

In your EstateCategoryPage_list.ss template then you would use <% loop EstateItemList %>

Make sure in your template you don't simply chuck $EstateItemList in as SilverStripe knows it's a list but not how you want to display it. You need to use <% loop %> to iterate over it.

many thanks that worked.

http://mydomain.com/property//list/29/Swansea/tolet

eg:
http://mydomain.com/property//$Action/$EstateCategoryPageID/$Area/$OfferStatus

http://doc.silverstripe.org/framework/en/topics/controller

I have
mysite > routes.yml
---
Name: myroutes
After: framework/routes#coreroutes
---
Director:
rules:
'property//$Action/$EstateCategoryPageID/$Area/$OfferStatus': 'EstateCategoryPage_Controller'

but this results in a error
[User Warning] popCurrent called on ModelAsController controller, but it wasn't at the top of the stack

basically i want to access more that the standard 2params of ID/OtherID
how i can use more than 2 params

for example: mydomain.com/mypage/myaction/PrmOne/PrmTwo/PrmThree

I can get my app to work by doing

mydomain.com/mypage/myaction?ECPID=whatevervalue&Area=whatevervalue&OfferStatus=whatevervalue
