@lukasbestle thanks for the tips!
I tinkered a bit and it’s works!
Controller is a good think, but it’s not necessary, you can you:
public function routes() {
return array(
array(
'pattern' => 'something/(:any)/(:any)',
'method' => 'get',
'action' => function($var1, $var2)
{
// do something
return response::json(array($var1));
}
)
);
}
The most important thing is to relate the route to the field URL:
http://www.sitename.COM/panel/pages/PAGE_NAME/field/FIELD_NAME_IN_BLUEPRINT/CUSTOM_FORM_FIELD_NAME/something/var1/var2
Thanks!
