What is the HTTP method and URI for the 'edit' action in a Laravel resource route?

Given a Laravel resource route defined as Route::resource('photos', PhotoController::class);, what is the HTTP method and URI that corresponds to the 'edit' action?

A GET /photos/{photo}/edit

B POST /photos/{photo}/edit

C GET /photos/edit/{photo}

D PUT /photos/{photo}/edit

💡 Hint

The 'edit' action shows a form to edit an existing resource and uses GET.

In Laravel resource routes, the 'edit' action uses the GET method and the URI pattern is /resource/{id}/edit. So for 'photos', it is GET /photos/{photo}/edit.

Which option correctly registers a resource route for 'posts' with only 'index' and 'show' actions?

You want to register a resource route for 'posts' but only want to include the 'index' and 'show' actions. Which code snippet is correct?

A Route::resource('posts', PostController::class)->except(['index', 'show']);

B Route::resource('posts', PostController::class)->include(['index', 'show']);

C Route::resource('posts', PostController::class)->only('index', 'show');

D Route::resource('posts', PostController::class)->only(['index', 'show']);

💡 Hint

Use the 'only' method with an array of action names.

The 'only' method accepts an array of action names to include. Option D uses the correct syntax. Option D is invalid because 'only' expects an array, not multiple arguments.

What is the route name generated for the 'destroy' action in a resource route for 'users'?

If you define Route::resource('users', UserController::class);, what is the name of the route generated for the 'destroy' action?

A users.delete

B users.destroy

C users.remove

D users.destroyUser

💡 Hint

Laravel uses the resource name plus the action name for route names.

Laravel generates route names by combining the resource name and the action name separated by a dot. For 'destroy' action on 'users', the route name is 'users.destroy'.

Why does this resource route registration cause a runtime error?

Consider this code: Route::resource('products', ProductController::class)->only('index', 'show'); When running, it throws an error. What is the cause?

A ProductController must be imported with a 'use' statement.

B The resource name 'products' must be singular, not plural.

C The 'only' method requires an array, not multiple string arguments.

D The 'only' method is not available on resource routes.

💡 Hint

Check the argument type passed to 'only'.

The 'only' method expects an array of action names. Passing multiple string arguments without an array causes a runtime error.

Which HTTP methods are included by default in a Laravel resource route?

When you define Route::resource('comments', CommentController::class);, which HTTP methods are automatically handled by the generated routes?

A GET, POST, PUT/PATCH, DELETE

B GET and POST only

C GET, POST, DELETE only

D GET, POST, PUT, PATCH, DELETE, OPTIONS

💡 Hint

Think about all CRUD operations and their HTTP verbs.

Laravel resource routes cover all CRUD operations: GET for index/show/edit/create, POST for store, PUT/PATCH for update, and DELETE for destroy.
