Hide parameter from URL

you mean get the id of an entry in a database?

you can use models ,one for each table to "model data" eg in model

public function getArticle($slug)

{
return $this->asArray()
    ->where(['slug' => $slug])
    ->first();

}

from controller i pass in $slug, from what gets returned i can get values across all fields, including id

No, what I mean to say is that I already have the ID and I'm passing it to a controller as a parameter. For example the URL will look like "localhost/controller/ID".

I don't want the ID to show on the URL so that users cannot mess around with URLs. Essentially I want to display only "localhost/controller" on the URL
