Form to make URL - Simple product chooser - forms

Question

I've created a products and services folders and items in SilverStripe CMS and everything is fine with it but I'd like to have a kind of product chooser.
I thought that I can make it through the form by drop-downs and when you will choose value 1 then you can pick from value 2 but what's the most important is when you click on submit I would like the form to construct a link/ url like: http://www.example.com/value1/value2 and automaticaly go there.
Simple: let's assume that I have upper section (called SAMSUNG) then inside of it I've products/ child pages (for example: Galaxy S3, Galaxy S4, Galaxy S5, etc.) and I want people to choose using this simple form: first choose manufacturer -> device type/ model/ name -> click submit (go) and it will take you directly to the right place: http://www.example.com/manufacturer/product
Is it possible to get URL like that through the form?

Answer 1

This would be easy enough. Basically what you want to do is have your form submit somewhere, then redirect to the desired URL using the submitted data from there.
In some controller
private static $allowed_actions = array(
'Form'
);
public function Form() {
$fields = new FieldList(
new DropdownField('Manufacturer', 'Manufacturer', array(
'Samsumg' => 'Samsumg',
'HTC' => 'HTC',
'Apple' => 'Apple'
)),
// It's necessary that first argument is Samsung as it will
// be used to fetch the device later on
new DropdownField('Samsumg', 'Samsumg', array(
'GalaxyS3' => 'Galaxy S3',
'GalaxyS4' => 'Galaxy S4',
'GalaxyS5' => 'Galaxy S5'
)),
// It's necessary that first argument is HTC as it will
// be used to fetch the device later on
new DropdownField('HTC', 'HTC', array(
'Desire' => 'Desire',
'Wildfire' => 'Wildfire',
'One' => 'One'
)),
// It's necessary that first argument is Apple as it will
// be used to fetch the device later on
new DropdownField('Apple', 'Apple', array(
'iPhne5' => 'iPhone 5',
'iPhone6' => 'iPhone 6',
'iPhone6Plus' => 'iPhone 6 Plus'
))
);
$actions = new FieldList(
new FormAction('submit', 'Search')
);
return new Form($this, 'Form', $fields, $actions);
}
public function submit($data, $form) {
// Get selected manufacturer
$manufacturer = $data['Manufacturer'];
// Get selected device by selected manufacturer
$device = $data[$manufacturer];
// Redirect to the manufacturer/device URL
return $this->redirect($manufacturer . '/' . $device);
}
Output the form by using $Form in your template.
