One epic thing with Laravel routing is the ability to quickly define routes with slash Parameters. What we mean by slash parameters is a URL that allows HTTP request like below –

localhost/myParam/myParam2

Defining Slash Parameters in Laravel

You would imagine setting up this type of functionality would be quite tricky, but, as Laravel always proves, it’s a really development-speed-boosting framework. Slash parameters are defined with the following syntax –

{categoryName?}

Have a read through the following tutorial to see how this syntax fits into routes.

Let’s start

In this tutorial, we will define a GET route to accept two parameters which will have names defined just like an ordinary query string.

Pre notes

For a small bit of context, I have created a HomeController of which’s index function returns the default welcome view.

Step 1

Head over to your routes/web.php file.

Step 2

For the tutorial’s sake, we will edit the route for the root URL which returns the welcome view.

The route currently looks like this –

Route::get('/', 'HomeController@index');

Now we can add some parameters, these will be CategoryName and ProductId.

Edit the route to look like the following

Route::get('/{categoryName?}/{productId?}', 'HomeController@index');

Step 3

Now with the route set with parameters, we can go to any of the following variations of URL.

• localhost/
• localhost/Clothing
• localhost/Clothing/4

Or similar.

Step 4

To test the values are being passed via the URL, head over to your HomeController or the controller that the route you edited is calling to.

Edit your controller to look something like the following –

public function index(Request $request)
    {

        if ($request->isMethod('GET')) {
            if (isset($request->categoryName)) {
                echo $request->categoryName . " ";
            }
            if (isset($request->productId)) {
                echo $request->productId;
            }
        }

        return view("welcome");
    }

Step 5

Now let’s go to URL of localhost/Clothing/5 and you will see that the parameters are printed to the page. Then, if you load just simply localhost/, no parameters will print!

Summary

Defining routes like this has endless variation and brilliant for dynamic web applications. As you can see from this tutorial, the layout of your routing file will totally depend on the type of application you are building.
