What is the URL generated by this named route?

Given the following Laravel route definition, what URL will be generated by calling route('profile.show', ['id' => 5])?

Laravel

Route::get('/user/{id}', function ($id) {
    return "User $id profile";
})->name('profile.show');

A /profile/show/5

B /profile/5

C /user?id=5

D /user/5

💡 Hint

Look at the route URL pattern and how parameters are passed in named routes.

The route is defined with URL pattern /user/{id}. Using route('profile.show', ['id' => 5]) replaces {id} with 5, so the generated URL is /user/5.

📝 Syntax

Which option correctly names a route in Laravel?

Select the correct syntax to assign the name 'dashboard.home' to a route that responds to GET requests at '/dashboard'.

A Route::get('/dashboard', function () {}, 'dashboard.home');

B Route::get('/dashboard', function () {})->name('dashboard.home');

C Route::name('dashboard.home')->get('/dashboard', function () {});

D Route::get('/dashboard', function () {})->setName('dashboard.home');

💡 Hint

Check the Laravel documentation for the method used to name routes.

The correct method to name a route is ->name('route.name') chained after the route definition. Option B uses this correctly.

What is the output of this route helper call?

Consider this route group with a name prefix. What is the output of route('admin.users.index')?

Laravel

Route::name('admin.')->group(function () {
    Route::get('/users', function () {
        return 'Users list';
    })->name('users.index');
});

A /users

B /admin/users

C /admin.users.index

D /users.index

💡 Hint

Name prefixes affect route names, not URLs.

The name prefix admin. adds to the route's name, making it admin.users.index. The URL remains /users because no URL prefix is set.

Why does this named route call cause an error?

Given this route definition, why does calling route('product.show') cause an error?

Laravel

Route::get('/product/{id}', function ($id) {
    return "Product $id";
})->name('product.show');

A Because the route callback function does not return a view.

B Because the route name 'product.show' is invalid and cannot be used.

C Because the route requires a parameter 'id' which was not provided in the route() call.

D Because the route URL '/product/{id}' is missing a trailing slash.

💡 Hint

Check if all required parameters are passed when generating URLs.

The route URL requires an 'id' parameter. Calling route('product.show') without passing 'id' causes an error because Laravel cannot generate the URL.

How does Laravel resolve route names with nested groups?

Given nested route groups with name prefixes, what is the full route name for the inner route?

Laravel

Route::name('api.')->group(function () {
    Route::name('v1.')->group(function () {
        Route::get('/items', function () {
            return 'Items list';
        })->name('items.index');
    });
});

A api.v1.items.index

B v1.api.items.index

C items.index

D api.items.index

💡 Hint

Name prefixes concatenate in the order of nesting.

Laravel concatenates name prefixes from outer to inner groups. So api. + v1. + items.index becomes api.v1.items.index.
