I need to compare products on my page.

The product-pages are grouped by holders.
My plan is to setup an arbitrary list of attribute-fields for each holder, that can be filled-in in the product-page administration.

Anyone around who can give assistance? Is there a best practice?

I think we'd need some more info... what is your dataobject page you are looking to compare, can you include code?

Thank you swaiba for your reply.

I do not have code to show yet. I'm just searching for the right approach.

To compare products I'll need to have extendable attribute keys which I'd like to declare with the product-group (holder).
But I've no idea how to store the values to each product.

No. It's just a product presentation, no shop.

Now here's my first approach:

class ProductAttribute extends DataObject {
static $db = array(
'Attribute' => 'Text',
'Value' => 'Text',
);

static $has_one = array(
      'ProductPage' => 'ProductPage',
);

static $field_names = array(
'Attribute' => 'Attribute',
'Value' => 'Value',
);

function getCMSFields_forPopup() {
   
$fields = new FieldSet();

    $attributes = DataObject::get('ProductHolderAttribute');
if ($attributes) {
       $attributes = $attributes->toDropdownMap('Title', 'Title', '(Select one)', true);
    }

    $fields->push(new DropdownField('Attribute', 'Attribute', $attributes));
    $fields->push(new TextField('Value', 'Value'));

return $fields;
}
}

In the page:

function getCMSFields() {

$fields = parent::getCMSFields();

$attributetable = new ComplexTableField(
$this,
'ProductAttributes', // relation name
'ProductAttribute', // object class
ProductAttribute::$field_names, // fields to show in table
ProductAttribute::getCMSFields_forPopup(), // form that pops up for edit
"ProductPageID = {$this->ID}", // a filter to only display item associated with this page
);
$fields->addFieldToTab('Root.Content.Specifications', $attributetable);
return $fields;
}
