Laravel 5.5 CRUD Tutorial From Scratch

Step 1: Installing The Laravel 5.5 Framework.

composer create-project --prefer-dist laravel/laravel Laravel55

It will create a directory and install all the Laravel specific dependencies.

Note: Here, we are not going to in detail about front end dependencies like Vue.js or React.js using Laravel Mix so, we are not going to install any of the Node dependencies right now.

Step 2: Setup a MySQL database in .env file.

Create one database in MySQL and then switch to your editor and open the .env file.

// .env DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=Laravel55 DB_USERNAME=root DB_PASSWORD=mysql

I have setup my local database credentials. You just need to change last three constants and you are ready to go.

Now, migrate two tables provided by Laravel 5.5. Switch to your terminal and type following command.

php artisan migrate

It will create two tables in your database.

users password_resets

Step 3: Create a model as well as migration file for our Products table.

Type the following command in your terminal.

php artisan make:model Product -m

It will create two files.

Product.php model. create_products_table migration file.

We need to create Schema for the products table. So navigate to Laravel55 >> database >> migrations >> create_products_table.

// create_products_table public function up() { Schema::create('products', function (Blueprint $table) { $table->increments('id'); $table->string('name'); $table->integer('price'); $table->timestamps(); }); }

So, for our products table, there will be 5 columns. timestamps() have 2 columns

created_at updated_at

Now, migrate the table by the following command.

php artisan migrate

In the database, you can see the products table.

Step 4: Make one view file to add the form data in the database.

Make one folder called products and then create a file in the resources >> views >> products >> create.blade.php and put the following code in it.

<!-- create.blade.php --> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Laravel 5.5 CRUD Tutorial With Example From Scratch </title> <link rel="stylesheet" href="{{asset('css/app.css')}}"> </head> <body> <div class="container"> <h2>Create A Product</h2><br /> <form method="post"> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="name">Name:</label> <input type="text" class="form-control" name="name"> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="price">Price:</label> <input type="text" class="form-control" name="price"> </div> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <button type="submit" class="btn btn-success" style="margin-left:38px">Add Product</button> </div> </div> </form> </div> </body> </html>

Step 5: Create one controller and route to display the Product form

Go to the terminal and type the following command.

php artisan make:controller ProductController --resource

It will create one controller file called ProductController.php and It has all the CRUD Functions, we need to seek.

Here, we have used resource parameter, so by default, It provides us some routing patterns, but right now, we will not see until we register one route in routes >> web.php file. So let us do it.

// web.php Route::resource('products','ProductController');

Now, switch to your terminal and type the following command.

php artisan route:list

You will see following route list.

Next step would be to go to ProductController.php file and add into create() function some code.

// ProductController.php /** * Show the form for creating a new resource. * * @return \Illuminate\Http\Response */ public function create() { return view('products.create'); }

After that, we need to start Laravel Development server. So in the terminal, hit the following command.

php artisan serve

Switch to the browser and hit this URL: http://localhost:8000/products/create

You will see the following screen.



Step 6: Put the Laravel 5.5 Validation in Product Form.

First, we need to apply an action to our product creation form.

<!-- create.blade.php --> <form method="post" action="{{url('products')}}">

Now, we need to handle CSRF issue. So, put the following code in the form

<!-- create.blade.php --> {{csrf_field()}}

We also need to handle Mass Assignment Exception. So we need to go to app >> Product.php file and in that put the protected $fillable property in it.

// Product.php protected $fillable = ['name','price'];

If you see the resource routes then it has post request has ‘/products‘ route and store function in ProductController.php file. So we need to code the store function in order to save the data in the database.

One thing to keep in mind that, we need to include the namespace of Product.php model in the ProductController.php file. So type the following line at the starting of ProductController.php file.

use App\Product;

Also, we need to put the validation there.

// ProductController.php /** * Store a newly created resource in storage. * * @param \Illuminate\Http\Request $request * @return \Illuminate\Http\Response */ public function store(Request $request) { $product = $this->validate(request(), [ 'name' => 'required', 'price' => 'required|numeric' ]); Product::create($product); return back()->with('success', 'Product has been added');; }

Now, if validation fails then we need to show an error. So go back to create.blade.php and put the following code after h2 tag.

<!-- create.blade.php --> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Laravel 5.5 CRUD Tutorial With Example From Scratch </title> <link rel="stylesheet" href="{{asset('css/app.css')}}"> </head> <body> <div class="container"> <h2>Create A Product</h2><br /> @if ($errors->any()) <div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> </div><br /> @endif @if (\Session::has('success')) <div class="alert alert-success"> <p>{{ \Session::get('success') }}</p> </div><br /> @endif <form method="post" action="{{url('products')}}"> {{csrf_field()}} <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="name">Name:</label> <input type="text" class="form-control" name="name"> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="price">Price:</label> <input type="text" class="form-control" name="price"> </div> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <button type="submit" class="btn btn-success" style="margin-left:38px">Add Product</button> </div> </div> </form> </div> </body> </html>

At last, go to the browser and hit the development Laravel URL: http://localhost:8000

If you submit the form without any value then, you can see the errors like below image.

If you fill all the values then, you will redirect to this page with the success message. So, here One thing must be noticed.

// ProductController.php public function store(Request $request) { $product = $this->validate(request(), [ 'name' => 'required', 'price' => 'required|numeric' ]); Product::create($product); return back()->with('success', 'Product has been added'); }

In Laravel 5.5 we directly get the array of the values return by validation function and use it to insert in the database, which is new feature in Laravel 5.5

Step 7: Make an index page to list the products.

For that, first, we need to send the data to the index.blade.php. So, in ProductController.php file, we need to write the code to fetch the data and return it to the index view.

// ProductController.php /** * Display a listing of the resource. * * @return \Illuminate\Http\Response */ public function index() { $products = Product::all()->toArray(); return view('products.index', compact('products')); }

In resources >> views >> products, create one blade file called index.blade.php file and put the following code in it.

<!-- index.blade.php --> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Index Page</title> <link rel="stylesheet" href="{{asset('css/app.css')}}"> </head> <body> <div class="container"> <br /> @if (\Session::has('success')) <div class="alert alert-success"> <p>{{ \Session::get('success') }}</p> </div><br /> @endif <table class="table table-striped"> <thead> <tr> <th>ID</th> <th>Name</th> <th>Price</th> <th colspan="2">Action</th> </tr> </thead> <tbody> @foreach($products as $product) <tr> <td>{{$product['id']}}</td> <td>{{$product['name']}}</td> <td>{{$product['price']}}</td> <td><a href="{{action('ProductController@edit', $product['id'])}}" class="btn btn-warning">Edit</a></td> <td> <form action="{{action('ProductController@destroy', $product['id'])}}" method="post"> {{csrf_field()}} <input name="_method" type="hidden" value="DELETE"> <button class="btn btn-danger" type="submit">Delete</button> </form> </td> </tr> @endforeach </tbody> </table> </div> </body> </html>

So, when you hit the URL: http://localhost:8000/products

Step 8: Make an edit view for update the products.

Our step will be to add the edit function in ProductController.php file and put the following code in it.

// ProductController.php /** * Show the form for editing the specified resource. * * @param int $id * @return \Illuminate\Http\Response */ public function edit($id) { $product = Product::find($id); return view('products.edit',compact('product','id')); }

Now, make an edit.blade.php file inside resources >> views >> products

<!-- edit.blade.php --> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Laravel 5.5 CRUD Tutorial With Example From Scratch </title> <link rel="stylesheet" href="{{asset('css/app.css')}}"> </head> <body> <div class="container"> <h2>Edit A Product</h2><br /> @if ($errors->any()) <div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> </div><br /> @endif <form method="post" action="{{action('ProductController@update', $id)}}"> {{csrf_field()}} <input name="_method" type="hidden" value="PATCH"> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="name">Name:</label> <input type="text" class="form-control" name="name" value="{{$product->name}}"> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <label for="price">Price:</label> <input type="text" class="form-control" name="price" value="{{$product->price}}"> </div> </div> </div> <div class="row"> <div class="col-md-4"></div> <div class="form-group col-md-4"> <button type="submit" class="btn btn-success" style="margin-left:38px">Update Product</button> </div> </div> </form> </div> </body> </html>

A further step would be to code the update function.

// ProductController.php /** * Update the specified resource in storage. * * @param \Illuminate\Http\Request $request * @param int $id * @return \Illuminate\Http\Response */ public function update(Request $request, $id) { $product = Product::find($id); $this->validate(request(), [ 'name' => 'required', 'price' => 'required|numeric' ]); $product->name = $request->get('name'); $product->price = $request->get('price'); $product->save(); return redirect('products')->with('success','Product has been updated'); }

Step 9: Delete the product.

// ProductController.php /** * Remove the specified resource from storage. * * @param int $id * @return \Illuminate\Http\Response */ public function destroy($id) { $product = Product::find($id); $product->delete(); return redirect('products')->with('success','Product has been deleted'); }
