joomla - router change url when getting the name of product - joomla

Question

I have build my own component in joomla and client wants now a friendly urls f.e
website.com/someplace/{product-id}-{product-name}. So i Build my own router like this.
function componentBuildRoute(&$query)
{
$segments = [];
if (isset($query['view'])) {
$segments[] = "szkolenie";
unset($query['view']);
}
if (isset($query['product_id'])) {
$productName = JFilterOutput::stringURLSafe(strtolower(getProductName($query['product_id'])));
$newName = $query['product_id'] . '-' . $productName;
$segments[] = $newName;
unset($query['product_id']);
}
return $segments;
}
and parse route function
function componentParseRoute($segments)
{
$app = JFactory::getApplication();
$menu = $app->getMenu();
$item =& $menu->getActive();
$count = count($segments);
switch ($item->query['view']) {
case 'catalogue' : {
$view = 'training';
$id = $segments[1];
}
break;
}
$data = [
'view' => $view,
'product_id' => $id
];
return $data;
}
While on the end of buildroute function segments are ok I have exactly what I want that on the beginning of parse route I have something like
website.com/szkolenie/1-krakow <-- I dont know wtf is this krakow( I know it is city i Poland) but still where is it get from ? The getProductName function implementation is
function getProductName($productId)
{
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select('#__component_training.id as id, #__component_product' . name)
->from($db->quoteName('#__component_training'))
->where('#__s4edu_product.product_id = ' . $productId)
->leftJoin('#__component_product ON
#__component_training.product_id=#__component_product.product_id');
$training = $db->loadObject();
return trim($training->name);
}
So taking all this into consideration I think that something is happening between the buildRoute and parseRoute, something what filters the $segment[1] variable, but how to disable that and why is it happening ?
P.S
Please do not send me to https://docs.joomla.org/Joomla_Routes_%26_SEF
I already know all the tutorials on joomla website which contains anything with sef.
P.S.S
It is built on joomla 3.7.0

Answer 1

You do not have a product named "krakow" ?
If not you can try to remove the $productName from the build function, just to check if this "krakow" is added automaticaly or it's from the getProductName() function.
Also i noticed that you have an error i guess in the function getProductName()
->where('#__s4edu_product.product_id = ' . $productId)
It's should be
->where('#__component_product.product_id = ' . $productId)
