Hi guys,

I assumed this would be easy, but am really struggling to find info in these forums...
I have "Apartments" stored as data objects:

class Apartment extends DataObject {
    //db fields
    static $db = array (
		'Type' => 'Text',
        'Title' => 'Varchar(255)',
		'Price' => 'Text',
		'Rooms' => 'Text',
		'Bathrooms' => 'Text',
        'Description' => 'Text',
		'URLSegment' => 'Varchar(255)',
		'OwnerName' => 'Varchar(255)',
		'isActive' => 'Boolean',

Now I have a page that currently just lists all of the apartments in a nice template:

  public function listAll ($filter = null){
	if(!isset($_REQUEST['start'])) $_REQUEST['start'] = 0;
		$filter = "isActive = '1'";
		if(!$filter){ return false; } else
		$limit = $_REQUEST['start'].",8";
		$sort = 'Created ASC'; 
	return DataObject::get('Apartment', $filter, $sort, null, $limit);

I'd just like to have the ability in the front end for users to filter the results by the attributes of each apartment, E.G - the apartment type, the price range, number of bedrooms etc.

I'm sure it's easy and I'm being a newb, but can somebody please help?

An exmaple form code would be amazing.

OK, I can get one filter to work from the URL paramter:

 public function listAll(){
	if(!isset($_REQUEST['start'])) $_REQUEST['start'] = 0;
		if(isset($_GET['isActive'])) {
		$isActive = Convert::raw2sql($_GET['isActive']);
		else {
		$isActive = '0';
		$filter = "isActive = '" . $isActive . "'";		
		$limit = $_REQUEST['start'].",8";
		$sort = 'Created ASC'; 
	return DataObject::get('Apartment', $filter, $sort, null, $limit);

and then I just have radio buttons etc onthe listing page which append parameters to the URL when clicked. I think this is on the right track?

can anybody shed any light on how I can add multiple filters?
What AAB did here:
is pretty much EXACTLY what I'm trying to achieve, please can anybody help??

can anyone shed any light on this AT ALL? am I even approaching this correctly or way of?

to clarify, my problem is this:
I have a website of holiday homes (Apartments)
each apartment is a dataobject
each apartment has lots of "amenities" which are also dataobjects

I can do something like this: $filter = "Price < " . $maxprice . "
or $filter = "AmenityID='1'"
which easily filters my page of apartments to just those with a maxprice that is set by the page URL - E.G - apartments?maxprice=100 or just those which are related to an Amenity with an ID of 1.

but how do i filter out using lots of options? E.G - I want users to be able to filter apartments that have a BBQ and a POOL

my "amenities" are in a seperate table: Amenity. And the relationship for "Apartment" to "Amenity" is $many_many
the relationship of "Amenity" to "Apartment" is $belongs_many_many

that all works fine, when creating "Apartment" DataObject I can specify what "Amenity" it has, and the links are seutp in the DB

but how can a user filter this data in the front end?

Basically, I want to be able to do this,3,5,7,12
(similar to what AAB did here:"
and that will display a list of apartments that have amenities with IDs of 1 AND 3 AND 5 AND 7 AND 12
at the moment, I can only do one amenity at a time...

some progress here:

$AmenityIDs = array(1,2,4);
$AmenityIDs = implode(',', $AmenityIDs);

$filter = "Price < $maxprice AND Price > $minprice AND isActive = $isActive AND AmenityID IN ($AmenityIDs)";
$sort = 'Created ASC';
$join = 'LEFT JOIN `Apartment_Amenities` ON `ApartmentID` = `Apartment`.ID';
$limit = $_REQUEST['start'].",10";

but that is just saying if the AmenityID is listed ANYWHERE in the array, then return the apartment, but I need it the apartment to match ALL of the IDs in the array, does that make sense?

Did you have any luck with this? I'm looking to do something very similar within the eCommerce module.

hi there

have you had a look at the code in generic-views? or probable you can even just use generic views. once i've used smth like this - it worked but as far as i remember i had some troubles filtering many_many's.

I tried a few different methods and never REALLY got to what I wanted.

I'm currently playing around with extending the SS search function, but this is a personal project so I don't get much time to work on it!
I might give up soon and pay one of my devs to sort it for me! Happy to share the results if/when i do...

here's the latest progress/attempt:

 public function SearchForm() {
        $context = singleton('Apartment')->getCustomSearchContext();		
        $extraFields = $context->getSearchFields();
		$fields = new FieldSet(
					new DropdownField(
			   			'RoomsMin', 'Min Rooms',  array( '' => 'Any', '1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' => '5', '6' => '6', '7' => '7', '8' => '8', '9' => '9', '10' => '10')),
					new DropdownField(
			   			'RoomsMax', 'Max Rooms',  array( '' => 'Any', '1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' => '5', '6' => '6', '7' => '7', '8' => '8', '9' => '9', '10' => '10')),
					new DropdownField(
						'Choose a town',
						Dataobject::get("Town")->toDropdownMap("ID", "Name", "Please Select")),
					new DropdownField(
						'Choose amenities',
						Dataobject::get("Amenity")->map("ID", "Name", "Please Select"))
        $form = new Form($this, "SearchForm",
            new FieldSet(
                new FormAction('doSearch', 'Search')

        return $form;
    public function doSearch($data, $form) {
        $context = singleton('Apartment')->getCustomSearchContext();
		//Add fields so that only published are shown.
		//$data['isActive'] = '1';
        $results = $context->getResults($data);
        return $this->customise(array(
            'Results' => $results
        ))->renderWith(array('SearchPage_results', 'Page'));
