Laravel 5 HTTP/Requests - pass url parameter to the rules() method

Question

I\'m trying to create a set of rules under the new \\HTTP\\Requests\\UpdateArticle class for the slug field, which needs to have unique fi

Answer 1

You can retrieve route parameters by name with input():

$id = Route::input('id');
return [
    // ...
    'slug' => 'required|unique:articles,id,' . $id,
    // ...
];

It's right there in the docs (scroll down to Accessing A Route Parameter Value)

Answer 2

To get URL parameters from the URL:

$this->route('id');
