how can I show parameters that get from database - php

Question

I want to do like twitter/instagram profile url address and I want to get data from database. like: example.com/{username}. But I can not do that because I'm beginner in Laravel. How can I do this? And I'm using Laravel 8 and are my last two routes correct?
My web.php is:
Route::get('/test', [HomeController::class, 'test'])->name('test');
Route::middleware(['auth:sanctum', 'verified'])->get('/profile', function () {
return view('design2.profile');
})->name('profile');
Route::middleware(['auth:sanctum', 'verified'])->get('/settings', function () {
return view('design2.settings');
})->name('settings');
My HomeController is:
public function test(){
return view('design2.test');
}
public function settings(){
return view('design2.settings');
}
public function profile(){
return view('design2.profile');
}

Answer 1

This documentation link that is going to help you: https://laravel.com/docs/8.x/routing#route-parameters
But here is a simple example
Route::get('/{username}', function ($username) {
// Logic to show the data
});

There's a few ways to do this, but the simplest way would look something like this:
Route::get('profile/{username}', [HomeController::class, 'profile']);
And then use the $username parameter from your controller like so:
public function profile($username){
// The following line assumes you have a model called "User"
// and a property / DB column called "username" that you're wanting in the URL.
// firstOrFail will return a 404 error automatically if the username isn't found
$user = User::where('username', $username)->firstOrFail();
return view('design2.profile', compact('user'));
}
Then in your design2.profile blade file $user can be used like so:
<h1>{{ $user->fullName}}'s Profile</h1>
<ul>
<li>First Name: {{ $user->firstName }}</li>
<li>Last Name: {{ $user->lastName}}</li>
<li>Email: {{ $user->email }}</li>
</ul>
