How do I pass a value in my Route to the Controller to be used in the View in Laravel? - laravel

I have 2 entities called Match and Roster.
My Match routes are like this
http://localhost:8888/app/public/matches (index)
http://localhost:8888/app/public/matches/14 (show)
In order to view/create the teams for each specific match I added the routes for the match roster like this:
Route::get('/matches/'.'{id}'.'/roster/', [App\Http\Controllers\RosterController::class, 'index']);
Now I need that {id} i have in my URL to pass it to the Controller here:
public function index()
{
return view('roster.index');
}
I need that for a couple of things. First I need to do a search on the Roster table filtering by a column with that value, so I can display only the players that belong to that match.
Second, I need to pass it on to the view so I can use it on my store and update forms. I want to add or remove players from the roster from that same index view.
How can I do that?

#1 You can get the route parameter defined on ur routes via request()->route('parameter_name').
public function index()
{
// get {id} from the route (/matches/{id}/roster)
$id = request()->route('id');
}
#2 You can pass the data object via using return view(file_name, object)
public function index()
{
// get {id} from the route (/matches/{id}/roster)
$id = request()->route('id');
// query what u want to show
// dunno ur models specific things, so just simple example.
$rosters = Roster::where('match_id', '=', $id);
// return view & data
return view('roster.index', $rosters);
}
#3 It can be done not only index but also others (create, store, edit, update)
In addition, STRONGLY RECOMMEND learn Official Tutorial with simple example first.
Like a Blog, Board, etc..
You need to know essentials to build Laravel App.

Most of the time, I prefer named routes.
Route::get('{bundle}/edit', [BundleController::class, 'edit'])->name('bundle.edit');
In controller
public function edit(Bundle $bundle): Response
{
// do your magic here
}
You can call the route by,
route('bundle.edit', $bundle);

How can I get data from multiple controllers into a Laravel Blade view?

I'm new with Laravel (and programming) and I'm a bit confused.
Using the Eloquent ORM I store in the database a list of pets and their info in a pets table with a Pet model and a Pet controller.
I also have a users table with User model.
Then I have an owner_pet table that contains foreing keys to user_id and pet_id, with an OwnerPet model and controller.
I have a view called 'pets' and I want there to be a form and a list of the user pets, only accesible by authenticated users.
I have this route:
Route::get('/pets', [App\Http\Controllers\HomeController::class, 'index'])->name('pets');
There, using the auth middleware it checks the user is logged in and returns the view 'pets', that contains a form to add pets.
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
return view('pets');
}
This works fine.
Then I have a pet controller with an add pet function, I use it with a form in the 'pets' view that calls this route:
Route::post('/add', 'PetController#addPet')->name('add');
When the pet is added I return the 'pets' view with a success message.
return view('pets')->with('success', $success);
This works fine.
Then I have a ownerPets index function where I get all the info I need and store it as $pets and call the 'list' view:
public function index()
{
$ownerPets = OwnerPet::leftjoin('pets', 'pets.id', '=', 'owner_pets.pet_id')
->where('user_id', Auth::user()->id)->paginate(20);
return view('list')->with('pets', $pets);
}
I call the function with this route:
Route::get('/list', 'OwnerPetController#index')->name('list');
This works fine, I can see the list of the user's pets.
But I need to have everything in the same view, and I can only call a single function from the route.
Do I need to make another controller and call all the functions from there and then send all the data to the view? I was told calling a controller from another controller was a bad practice, but I can't think of another way to do this.
Can I maybe make a view that contains the other 2 views? But I don't know how would I get the functions to pass the data to them.
Please I need some advice. Thanks.
This mean that you want a page which have add form at the right side and list of pet with owner information at the left (for example).
so, you just
This Route::get('/list', 'OwnerPetController#index')->name('list'); will return list pet and add from for the same page.
Create another route like Route::post('/add', 'PetController#addPet')->name('add'); (in the same controller or other controller, it up to you) for adding pet.
after you fill up the form and click submit, addPet function must return view('pets');
Hope martch your question.
Thanks

Laravel 8 - friendly url that call multiple controllers depending on match (products, categories, pages) - How to design it?

i would like to build a route that catch clean seo friendly url and call correct controller to display page. Examples:
https://mypage.com/some-friendly-url-separated-with-dashes [PageController]
https://mypage.com/some-cool-eletronic-ipod [ProductController]
https://mypage.com/some-furniture-drawers [CategoryController]
So I have in app route:
Route::get('/{friendlyUrl}', 'RouteController#index');
Each friendly url is a unique url(string) so there is no duplicate between pages/products/categories. There is also no pattern between urls - they could be any string used in seo(only text plus dashes/ sometimes params).
Is it wise to build one db table that keeps all urls in on place with info what to call ( url | controller_name | action_name) - as an example.
Another question is - how to call different controllers depending on url used? (for above example -> RouteController catch friendly urls -finds match in db table -> then calls correct controller)
Many thanks for any help.
Have a nice day

There's two approaches you can take to this.
Proactive:
In web.php
$slugs = Product::pluck('slug');
foreach ($slugs as $slug) {
Route::get($slug, 'ProductController#index');
}
$slugs = Category::pluck('slug');
foreach ($slugs as $slug) {
Route::get($slug, 'CategoryController#index');
}
$slugs = Page::pluck('slug');
foreach ($slugs as $slug) {
Route::get($slug, 'PagesController#index');
}
Then you can determine the product in the appropriate controler via e.g.
$actualItem = Product::where('slug', request()->path())->first();
The downside to this approach is that all routes are registered on every request even if they are not used meaning you hit the database on every request to populate them. Also, routes can't be cached when using this approach.
Reactive:
In this approach you use the fallback route:
In web.php:
Route::fallback(function (Request $request) {
if (Page::where('slug', $request->path())->exists()) {
return app()->call([ PageController::class, 'index' ]);
}
if (Category::where('slug', $request->path())->exists()) {
return app()->call([ CategoryController::class, 'index' ]);
}
if (Product::where('slug', $request->path())->exists()) {
return app()->call([ ProductController::class, 'index' ]);
}
abort(404);
});
You need create a table call slugs.
Then create a unique slug (can be auto generated or specified) for each page, product, category.
slug records also have columns to get Controller and params, ex: type and id
It'd be better if you just use a prefix for each type like this:
https://mypage.com/pages/some-friendly-url-separated-with-dashes [PageController]
https://mypage.com/products/some-cool-eletronic-ipod [ProductController]
https://mypage.com/category/some-furniture-drawers [CategoryController]
Then for achieving this, create three routes like this
Route::get('pages/{friendlyUrl}', 'PageController#index');
Route::get('products/{friendlyUrl}', 'ProductController#index');
Route::get('category/{friendlyUrl}', 'CategoryController#index');
These URLs would be SEO friendly

Laravel route difference between {id} vs {tag}

I am new in Laravel pardon me if question is silly. I have seen a doc where they used
For get request
Route::get("tags/{id}","TagsController#show");
For put request
Route::put("tags/{tag}","TagsController#update");
What is the difference and benefit between this ? I understood 1st one, confusion on put route.
There’s no real difference as it’s just a parameter name, but you’d need some way to differential parameters if you had more than one in a route, i.e. a nested resource controller:
Route::get('articles/{article}/comments/{comment}', 'ArticleCommentController#show');
Obviously you couldn’t use just {id} for both the article and comment parameters. For this reason, it’s best to use the “slug” version of a model for a parameter name, even if there’s just one in your route:
Route::get('articles/{article}', 'ArticleController#show');
You can also use route model binding. If you add a type-hint to your controller action for the parameter name, Laravel will attempt to look up an instance of the given class with the primary key in the URL.
Given the route in the second code example, if you had a controller that looked like this…
class ArticleController extends Controller
{
public function show(Article $article)
{
//
}
}
…and you requested /articles/123, then Laravel would attempt to look for an Article instance with the primary key of 123.
Route model binding is great as it removes a lot of find / findOrFail method calls in your controller. In most instances, you can reduce your controller actions to be one-liners:
class ArticleController extends Controller
{
public function show(Article $article)
{
return view('article.show', compact('article'));
}
}
Generally there's no practical difference unless you define a custom binding for a route parameter. Typically these bindings are defined in RouteServiceProvider as shown in the example in the docs
public function boot()
{
parent::boot();
Route::model('tag', App\Tag::class);
}
When you bind tag this way then your controller action can use the variable via model resultion:
public function update(Tag $tag) {
// $tag is resolved based on the identifier passed in the url
}
Usually models are automatically bound so doing it manually doesn't really need to be done however you can customise resolution logic if you do it manually
Normal way
Route::get("tags/{id}","TagsController#show");
function($id)
{
$tag = Tag::find($id);
dd($tag); // tag
}
With route model bindings
Route::put("tags/{tag}","TagsController#update");
function(Tag $tag) // Tag model binding
{
dd($tag); // tags
}
ref link https://laravel.com/docs/5.8/routing#implicit-binding
It's just a convention. You can call it all you want. Usually, and {id} refers to the id in your table. A tag, or similarly, a slug, is a string value. A tag could be 'entertainment' for video categories, while 'my-trip-to-spain' is a slug for the description of a video.
You have to chose the words what you are comfortable with. The value will be used to find in your database what record is needed to show the correct request in the view. Likewise you can use video/view/{id}/{slug} or any combination thereof.
Just make sure your URLs don't get too long. Because search engines won't show your website nicely in search results if you do. Find the balance between the unambiguous (for your database) and logic (for your visitors).
Check this out: Route model bindings
Use id, Laravel will get the id from route, and it will be the tag's id, it is integer.
function show($id) {
$tag = Tag::find($id);
}
Use tag, Laravel automatically resolves Eloquent models defined in routes or controller actions whose type-hinted variable names match a route segment name.
In URL, your tag parameter is integer, however in your controller action $tag will be a model object:
function action(Tag $tag) {
$tag->name;
}
So you don't need to get the $tag by eloquent in your controller action. You just need to specify it is From model Tag $tag
It will do it automatically.

Laravel Routing - Best way to differentiate routes with same format

Say I have a database of items, each belonging to a country, county and a city. I want to have routes to list all of the items within a singular country, county or a city. Each country/county/city has a slug, for example france for France that is to be used in URL.
I want all the routes to have the same format:
/items-in-{slug}, so for example /items-in-france or /items-in-paris.
However, the slug can be a slug of one of multiple Models. What is the best set up for this sort of situation? I can think of 3 main options:
A single route that will catch all matching URLs, which will run a specialised RoutingController or similar, which will then in turn check which Model slug represents and propogate to the correct controller method (for example, viewInCountry($slug) or viewInCity($slug))
One route for each type of Model, and putting restrictions on each route that would only accept one of the existing slugs (i.e. fetch all of the slugs and generate a regex that will only accept one of the existing slugs)
Fetch all Models (countries/cities/counties) and generate a Route for each one
All options seem a little hacky and I am wondering if there is a more elegant solution to this.
I would go for the second option, except don't use a regex to accept existing slugs. Instead you could write your own model route binding resolution logic as mentioned here under 'Customizing The Resolution Logic'. Something like this could probably do the trick:
// Put this in your RouteServiceProvider.php
public function boot()
{
parent::boot();
Route::bind('slug', function ($value) {
$country = App\Country::where('slug', $value)->first();
if ($country !== null) {
return $country;
}
$city = App\City::where('slug', $value)->first();
if ($city !== null) {
return $city;
}
// Repeat for each model.
// 404 in case no model has been matched.
abort(404).
});
}
Alternatively if you are willing to adjust the url a bit, then you could create a route and a controller per model. That would require you to have urls like /items/france or items/paris etc.

Implicit route, with firstOrCreate instead of findOrFail

Is it possible to create an implicit route where if it is not found the thing is created? I am using Laravel 5.5.13.
For instance this is my implicit route:
Route::post('thumbs/{player}', 'ThumbController#store');
And in my controller it is this:
public function store(Request $request, Player $player)
{
$thumb = new Thumb($request->all());
$player->thumbs()->save($thumb);
return response()->json($thumb, 201);
}
So now if I go to the endpoint of ..../api/thumb/1 it will create a thumb related with Player of id 1. However instead of a id number I wanted to provide it a string like this:
..../api/thumb/PLAYER_NAME
So example of ..../api/thumb/Blagoh, then my endpoint should first find if a player exists by name "Blagoh", and if it doesn't then it should create it. I couldn't figure this one out.
What you should do is adding into boot method of RouteServiceProvider something like this:
Route::bind('player', function ($value) {
if ($player = \App\Player::find($value)) {
return $player;
}
return Player::create(['name' => $value]);
});
It's called explicit binding and you can update logic as showed above. Reference - Route model binding
