Hi there,
Is there a way to send form data to an external URL after the form has been returned? setFormAction only works before.

public function PayForm() {
				  
        $fields = new FieldList(
            TextField::create('USER1', 'Name and Surname'),
			TextField::create('EMAIL', 'Email')			
        );

        $actions = new FieldList(
            FormAction::create("doPayment")->setTitle("Pay Now")
        );

        $required = new RequiredFields('Name');
        $form = new Form($this, 'PayForm', $fields, $actions, $required);
		$form->setFormMethod('GET');
        return $form;
    }
               
               
    public function doPayment($data, Form $form) {
		$data['CHECKSUM'] = md5($data['NAME'].$data['SURNAME']);
		$form = new Form($this, 'doPayment', $fields, $actions, $required);

		//Send data to URL here
		
	}
}
