LARAVEL - Resource controller

Base controller: php artisan make:controller <pascal-name>

Resource controller: php artisan make:controller <pascal-name>

A resource controller is able to handle CRUD(create, read, update, delete) operations of a DB.

Template:

<?php

namespace App\Http\Controllers;
use App\Comics;
use Illuminate\Http\Request;

class ComicsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        //selects all data from DB and return an ouput page with retrived data
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //returns a page with a form to create a new DB row  
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //called by function create, stores form data into DB
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show(Comics $comic)
    {
        //returns an output page with data of 1 DB row
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit(Comics $comic)
    {
        //returns a page with a form to update 1 existing row
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Comics $comic)
    {
        //called by edit, stores form data into DB
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy(Comics $comic)
    {

    }
}

Best practice: create a subdirectory of /view with the name of the desired class
/comics

• /index.blade.php -> output all DB table data
• /create.blade.php -> form to create a new DB row
• /edit.blade.php -> form to update an existing DB row
• /show.blade.php -> output 1 specific DB row

CREATE

ComicsController.php create() /comics/create :

public function create()
{

    return view('comics.create'); # form
}

/view/comics/create.blade.php :

<form action="{{route('comics.store')}}" method="POST"> #send data to DB
    #checks that form data is from page form
    @csrf
    <div class="input-group mb-3">
