Understanding route parameters is essential for backend web development with Laravel, enabling dynamic and user-friendly URLs.

1

Create a basic route with a parameter

Create a route using Route::get with the URL pattern '/user/{id}' and a closure function that accepts $id as a parameter.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Create a route with URL '/user/{id}' and a closure that accepts $id
// Your code here

Need a hint?

Use Route::get with the URL pattern containing {id} and a closure with $id parameter.

2

Add a variable to hold the user ID

Inside the closure, create a variable called userId and assign it the value of the $id parameter.

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/user/{id}', function ($id) {
    // Create a variable userId and assign $id
    // Your code here
});

Need a hint?

Assign the route parameter $id to a new variable $userId.

3

Return a view passing the user ID

Modify the closure to return the view named 'user' and pass the variable userId to the view using compact('userId').

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/user/{id}', function ($id) {
    $userId = $id;
    // Return the 'user' view passing userId
    // Your code here
});

Need a hint?

Use return view('user', compact('userId')); to send the variable to the view.

4

Create the user view to display the user ID

Create a Blade view file named user.blade.php in the resources/views folder. Inside it, display the text User ID: followed by the $userId variable using Blade syntax.
