CRUD Application With Image Upload Using Laravel 8, jQuery - Ajax, SweetAlert & DataTable



In this post, I'm going to show you how to develop a complete CRUD (CREATE, READ, UPDATE, DELETE) application with Image Upload using Laravel 8, Bootstrap 5, jQuery - Ajax, DataTable, SweetAlert 2 and Bootstrap Icons.

I'm using Laravel 8 framework as Backend, Bootstrap 5 for designing the application, jQuery - Ajax for sending HTTP requests to the server, DataTable for pagination, sorting & searching, SweetAlert 2 for displaying nice designed alert boxes and Bootstrap Icons for some icons.

Now just follow all the steps very carefully one by one. don't worry I'll share all the codes here so just copy and paste them into your application.

Step 1: Installing Laravel 8

First, you have to install a fresh Laravel 8 application using composer, for this, you just have to open your terminal and run the below command.

composer create-project laravel/laravel crud-ajax

Step 2: Database Configuration

Now in this step, you have to write your database credentials into the .env file, but first, open your phpmyadmin and create a new database with the name crud_ajax. Now just see the below codes, if you have set any username or password other than mine then just write your own credentials.

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=crud_ajax
DB_USERNAME=root
DB_PASSWORD=

Step 3: Creating Model, Migration and Controller

In this step, we'll create our Model, Migration and Controller using a single command.

php artisan make:model Employee -mc

I've used the -m flag to create a migration, c flag to create a controller. After running the above command a Model with the name Employee.php a controller with the name EmployeeController.php and migration with the name 2021_07_28_100014_create_employees_table.php will be created.

Step 4: Defining Schema

Now in this step, we'll define our employees table schema so for this just open database/migrations/2021_07_28_100014_create_employees_table.php  and just use the below codes.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateEmployeesTable extends Migration {
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up() {
        Schema::create('employees', function (Blueprint $table) {
            $table->id();
            $table->string('first_name');
            $table->string('last_name');
            $table->string('email');
            $table->string('phone');
            $table->string('post');
            $table->string('avatar');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down() {
        Schema::dropIfExists('employees');
    }
}

Now you have to run this migration by the following command:

php artisan migrate

Step 5: Creating Routes

Now in this step, We'll create routes for our CRUD application. Just use the below codes.

<?php

use App\Http\Controllers\EmployeeController;
use Illuminate\Support\Facades\Route;

Route::get('/', [EmployeeController::class, 'index']);
Route::post('/store', [EmployeeController::class, 'store'])->name('store');
Route::get('/fetchall', [EmployeeController::class, 'fetchAll'])->name('fetchAll');
Route::delete('/delete', [EmployeeController::class, 'delete'])->name('delete');
Route::get('/edit', [EmployeeController::class, 'edit'])->name('edit');
Route::post('/update', [EmployeeController::class, 'update'])->name('update');

Step 6: Working in Model

Now in this step, we'll write some codes in the Post model. So for this just open the app/Models/Employee.php file and put the below codes.

<?php

namespace AppModels;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Employee extends Model {
    use HasFactory;
    protected $fillable = [
        'first_name',
        'last_name',
        'email',
        'phone',
        'post',
        'avatar'
    ];
}

Step 7: Working in Controller

Now, this is the most important step, In this, we'll write all the application logic. So for this just open the app/Http/Controllers/EmployeeController.php file and define each method like the below codes you can copy and paste the below codes.

<?php

namespace App\Http\Controllers;

use App\Models\Employee;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class EmployeeController extends Controller {

	// set index page view
	public function index() {
		return view('index');
	}

	// handle fetch all eamployees ajax request
	public function fetchAll() {
		$emps = Employee::all();
		$output = '';
		if ($emps->count() > 0) {
			$output .= '<table class="table table-striped table-sm text-center align-middle">
            <thead>
              <tr>
                <th>ID</th>
                <th>Avatar</th>
                <th>Name</th>
                <th>E-mail</th>
                <th>Post</th>
                <th>Phone</th>
                <th>Action</th>
              </tr>
            </thead>
            <tbody>';
			foreach ($emps as $emp) {
				$output .= '<tr>
                <td>' . $emp->id . '</td>
                <td><img src="storage/images/' . $emp->avatar . '" width="50" class="img-thumbnail rounded-circle"></td>
                <td>' . $emp->first_name . ' ' . $emp->last_name . '</td>
                <td>' . $emp->email . '</td>
                <td>' . $emp->post . '</td>
                <td>' . $emp->phone . '</td>
                <td>
                  <a href="#" id="' . $emp->id . '" class="text-success mx-1 editIcon" data-bs-toggle="modal" data-bs-target="#editEmployeeModal"><i class="bi-pencil-square h4"></i></a>

                  <a href="#" id="' . $emp->id . '" class="text-danger mx-1 deleteIcon"><i class="bi-trash h4"></i></a>
                </td>
              </tr>';
			}
			$output .= '</tbody></table>';
			echo $output;
		} else {
			echo '<h1 class="text-center text-secondary my-5">No record present in the database!</h1>';
		}
	}

	// handle insert a new employee ajax request
	public function store(Request $request) {
		$file = $request->file('avatar');
		$fileName = time() . '.' . $file->getClientOriginalExtension();
		$file->storeAs('public/images', $fileName);

		$empData = ['first_name' => $request->fname, 'last_name' => $request->lname, 'email' => $request->email, 'phone' => $request->phone, 'post' => $request->post, 'avatar' => $fileName];
		Employee::create($empData);
		return response()->json([
			'status' => 200,
		]);
	}

	// handle edit an employee ajax request
	public function edit(Request $request) {
		$id = $request->id;
		$emp = Employee::find($id);
		return response()->json($emp);
	}

	// handle update an employee ajax request
	public function update(Request $request) {
		$fileName = '';
		$emp = Employee::find($request->emp_id);
		if ($request->hasFile('avatar')) {
			$file = $request->file('avatar');
			$fileName = time() . '.' . $file->getClientOriginalExtension();
			$file->storeAs('public/images', $fileName);
			if ($emp->avatar) {
				Storage::delete('public/images/' . $emp->avatar);
			}
		} else {
			$fileName = $request->emp_avatar;
		}

		$empData = ['first_name' => $request->fname, 'last_name' => $request->lname, 'email' => $request->email, 'phone' => $request->phone, 'post' => $request->post, 'avatar' => $fileName];

		$emp->update($empData);
		return response()->json([
			'status' => 200,
		]);
	}

	// handle delete an employee ajax request
	public function delete(Request $request) {
		$id = $request->id;
		$emp = Employee::find($id);
		if (Storage::delete('public/images/' . $emp->avatar)) {
			Employee::destroy($id);
		}
	}
}

We have stored all the images in the storage directory so to access those images from the public directory we have to run a simple command:

php artisan storage:link

We are storing all the images in the storage/images directory.

Step 8: Working in View

In this step, We'll create only a single view file. Here we'll use the Bootstrap 5 framework for designing this application.

Create a new file inside resources/views with the name index.blade.php. Now, this is the main file from this file we'll write all the designing codes, writes all jquery codes to send HTTP requests to the server.  So just copy and paste the below codes into your index.blade.php file.

      }
    });

I've included all the CDN links of libraries that I'm using in this application.

Step 9: Serve The Application

Now our application is ready to be served. You just need to run a command to run your CRUD Application. Just use the below command in your terminal:

php artisan serve
