Laravel — P24: Controllers Intro

If you haven’t created the TestController, it’s time to do so now. I’m going to be using the one from the previous article, but the artisan command to create it is: php artisan make:controller TestController.

Creating the Route

Our first task is to create the route. The URL will contain a parameter that will be passed to the Controller’s method.

<?php
use App\Http\Controllers\TestController;

Route::get('/test-controller/id/{id}', [TestController::class, 'edit']);

We don’t have to explicitly state that we’re sending the {id} argument to the edit method in the TestController within our route file.

Accepting the Argument

Accepting the argument in the TestController is as simple as defining the $id parameter in our edit method.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TestController extends Controller
{
    // ...

    public function edit($id)
    {
        return "If we were editing, this would be for " . $id;
    }
}

We can now visit our routehttp://0.0.0.0/test-controller/edit/3 and see the results, which will display If we were editing, this would be for 3.

Multiple Arguments

It’s pretty self explanatory, but you can pass multiple arguments. Just make sure that they’re defined in order that you pass them inside of your route.

<?php

Route::get('/test-controller/delete/{id}/name/{name}', [TestController::class, 'delete']);

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TestController extends Controller
{
    // ...

    public function delete($id, $name)
    {
        return "Record " . $id . " has been deleted for " . $name;
    }
}

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TestController extends Controller
{
    // ...

    public function delete($user_id, $user_name)
    {
        return "Record " . $user_id . " has been deleted for " . $user_name;
    }
}

I don’t recommend it, but it does work. I normally like to keep it consistent and match the URL parameter with the method parameter.

Next time, we’ll look at Single Action Controllers. See you then.
