Laravel CRUD Operations

In this tutorial we are going to initiate Laravel CRUD operations project for learning.

Note: Before you start install laravel you need to install composer package installer in your system. Follow the steps.

Step 1: Composer Installation

To Install composer in your system click here

Step 2: Create new project via Composer

For creating a new project via a composer. you need to run a command in command line console or terminal.

cmd: composer create-project --prefer-dist laravel/laravel mysite

Note: You will see list of directories where you run above command. let's discuss most important directories.

app - this directory contains list of models, http > controllers directory. This is a important directory where you write a controller and model.
public - this directory contains assets like Image files, CSS files, Script files.
resources - this directory contains views.
routes - this directory contains all routes. Routes for specific URL.
.env - this file contains configuration for database.

Step 3: Start a local server

There is also command for starting a server.

cmd: php artisan serve

Step 3: Create database

Create database with name of crud.
Create database table books.

	CREATE SCHEMA `new_schema` ;

CREATE TABLE `books` (
   `book_id` int(11) NOT NULL AUTO_INCREMENT,
   `book_name` varchar(45) DEFAULT NULL,
   `book_price` decimal(4,0) DEFAULT NULL,
   PRIMARY KEY (`book_id`)
 ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=latin1

Step 4: Set Connection with database

Set the database name like crud
Set the username like root
Set the password if there is.

filename: .env

APP_NAME=Laravel
APP_ENV=local
APP_KEY=
APP_DEBUG=true
APP_LOG_LEVEL=debug
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=crud
DB_USERNAME=root
DB_PASSWORD=

BROADCAST_DRIVER=log
CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=

Step 5: Create Controller

define a function for getting welcome file.
define a function for save or update a book model.
define a function to retrieve list of books.
define a method to delete a book.

filename: Controller.php

<?php
namespace App\Http\Controllers;

use App\Books;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Http\Request;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
    public function getIndex(){
        return view("welcome");
    }

    public function saveOrUpdate(Request $request){
        $book = new Books;
        if($request->book_id){
            $book = Books::find($request->book_id);
        }
        $book->book_name = $request->name;
        $book->book_price = $request->price;
        $result = $book->saveOrFail();
        if($result){
            return response()->json(array('message'=>'Record successfully saved or updated'));
        }else{
            return response()->json(array('message'=>'Failed to saved or updated'));
        }
    }

    public function getList(){
        $books = Books::all();
        return response()->json(array('data' => $books));
    }

    public function deleteRecord(Request $request){
        $book = Books::find($request->book_id);
        $book->delete();
        return response()->json(array('message'=>'Record deleted successfully!'));
    }
}

Step 6: Create a view

create a view for showing data table and form for input.
add jQuery for manipulation of adding, deleting and showing data in view.

filename: welcome.blade.php

<!doctype html>
<html lang="{{ app()->getLocale() }}">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>

        <title>Laravel</title>
    </head>

    <body onload="load();">
        <meta name="csrf-token" content="{{ csrf_token() }}" />
        <input type="hidden" id="book_id">
        Book Name <input type="text" id="name" required="required" name="name"><br>
        Price: <input type="number" id="price" required="required" name="price"><br>
        <button onclick="submit();">Submit</button>

        <table id="table" border=1>
            <tr> <th> Name </th> <th> Price </th> <th> Edit </th> <th> Delete </th> </tr>
        </table>

        <script type="text/javascript">

            $.ajaxSetup({
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                }
            });

            data = "";
            submit = function(){
                    $.ajax({
                        url:'api/saveOrUpdate',
                        type:'POST',
                        data:{book_id:$("#book_id").val(),name:$('#name').val(),price:$('#price').val()},
                        success: function(response){
                            alert(response.message);
                            load();
                        }
                    });
                };

            load = function(){
                $.ajax({
                    url:'api/list',
                    type:'POST',
                    success: function(response){
                        data = response.data;
                        $('.tr').remove();
                        for(i=0; i<response.data.length; i++){
                            $("#table").append("<tr class='tr'> <td> "+response.data[i].book_name+" </td> <td> "+response.data[i].book_price+" </td> <td> <a href='#' onclick= edit("+i+");> Edit </a>  </td> </td> <td> <a href='#' onclick='delete_("+response.data[i].book_id+");'> Delete </a>  </td> </tr>");
                        }
                    }
                });
            };

            edit = function (index){
                $("#book_id").val(data[index].book_id);
                $("#name").val(data[index].book_name);
                $("#price").val(data[index].book_price);
            };

            delete_ = function(id){
                $.ajax({
                    url:'api/delete',
                    type:'POST',
                    data:{book_id:id},
                    success: function(response){
                        alert(response.message);
                        load();
                    }
                });
            }

        </script>
    </body>
</html>

Step 7: Finally update Route web.php and api.php

update web.php file for getting main view to display.
update api.php file for api level operations.

filename: web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/','Controller@getIndex')->name('index');

filename: api.php

<?php

use Illuminate\Http\Request;

/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

Route::post('saveOrUpdate','Controller@saveOrUpdate')->name('saveOrUpdate');
Route::post('list','Controller@getList')->name('list');
Route::post('delete','Controller@deleteRecord')->name('delete');
