How To Route in Laravel
It’s a difficult thing when it comes to thinking how to approach the learning process. I’m not a big fan of learning a specific concept, like Controllers, right away. I believe that you learn the best by moving slowly through the concepts. I’ll try to present these concepts in a strategic order. Hopefully it works for you.
The purpose of this article is to see how we would normally get to a specific view. The only view that we have currently is the welcome
view. If we wanted to modify what the user sees right now, what would we need to do? Lets go through it.
Start by opening the project that we built in the previous article in your IDE.
Navigate to routes/web.php
. You should see the following file.
<?php
use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
Route::get('/', function () {
return view('welcome');
});
This is the route file. When a user enters a URL into their browser, this is where they end up. We use a Route
facade to funnel the users request to a specific page.
Route::get()
is stating that we’re receiving a get
request from the browser. You’re probably aware that there are multiple types of requests that we can process, such as: get
, post
, put
, and delete
. The Route facade allows us to capture each of those requests.
GET
: used to request data from the server. Data can be sent to the server through the address bar as key/value pairs. You’ve probably seen an address like this: https://www.dinocajic.com/?p=123. In this case, p
is the key and 123
is the value. In this instance, it just returns an image.
POST
: used to send data to the server. Most of the time, the data that’s sent to the server via post
is done through a form. The form field will have a name
attribute, which will be the key and the data that’s entered by the user will be the value. For example, <input type="text" name="full_name">
will have a key of full_name
and the data that the user enters, i.e. Dino Cajic
, will be the value. Unlike the get
method, data submitted via the post
request is not visible to the user in the URL.
PUT/PATCH
: Sends data to the server notifying it that the resource is going to be updated. There are a couple of differences on when to use one over the other, but they both update the resource. Most of the time, it’s just based on developer preference as to which one is used. Frameworks like Laravel allow for resource management by easily funneling requests like this one through. Can you use the post
request to update something in the database? Of course. You’re still sending data to the server. This is just more explicit.
DELETE
: Similar to the put/patch
request, this is another explicit request that allows for data to be sent to the server. In this case, we’re specifying that we want to delete a resource.
web.php
route file.Route::get('/', function () {
return view('welcome');
});
get
method is the URL address parameter. The forward slash means that we’re on the main page. For example, https://example.com
. If we went to an about page, we might have a URL that looks like this: https://example.com/about
. What would the route look like for the about page?Route::get('/about', function () {
return view('welcome');
});
function () {
return view('welcome');
}
It just returns a view
global helper function. The view
global helper accepts the name of the view that we’ll need to return. In this case, welcome
. Where is it located? The welcome
view is located in the resources/views/
directory. If you expand it in your IDE, you’ll see the welcome.blade.php
file. Don’t worry about the .blade
extension right now: we’ll take a look at it in detail soon. For now, just think of it as a way to write “php” code without using php syntax.
Let’s open the resources/views/welcome.blade.php
file.

It’s an HTML file that generates your main page.
@if (Route::has(‘login’))
. This is the blade syntax that we just talked about. Let’s copy some of the content and create a new page. I’m going to use the main page as links to all the tutorials that we cover. First of, right click on your resources/views
folder and create a new php file: index.blade.php
. Paste the following code into it.<!DOCTYPE html>

You should see that file in your directory.
web.php
file and change welcome
to index
.<?php
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('index');
});
welcome.blade.php
file. Copy the previous route and paste it underneath your first route.<?php
use Illuminate\Support\Facades\Route;
Route::get('/', function () {
return view('index');
});
Route::get('/welcome', function () {
return view('welcome');
});
How do we access the welcome
view now from our browser. Just go to http://0.0.0.0/welcome.
If this was deployed to your production server, you would go to https://example.com/welcome
.
You will see your welcome
view.
That’s it for this one. Nice and simple. See you in the next one.
