Install Laravel 8 App

First Step, you need to download or install laravel web application new setup on your local machine. you can use the following command to download or install laravel application new setup:

composer create-project laravel/laravel blog –-prefer-dist

If you want to install a specific version of laravel, you can follow the following tutorial

Configure Database Detail

After that, you will set up the database credentials in .env file. So open your .env file and update database credentials following:

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

Create Model and Migration

Next, we need to create a model and migration in your laravel web application using the php artisan make:model model_name -m. So run the following command in your project root directory.

Go to the command prompt

cd/project_root_directory

php artisan make:model Image -m

after that, go to database/migrations/ and find created migration file and add fields, as you want to in your database table.

Your migration file looks like:

<?php

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

class CreateImagesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('Images', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('title');
            $table->timestamps();
        });
    }

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

Run Migration

Next, go to command prompt and run the following command:

php artisan migrate
OR
php artisan migrate:fresh

This php artisan migrate command creates a table in your database.

Create Routes

Next step, go to routes/web.php file and update the following routes into your file:

use App\Http\Controllers\ImageController;


Route::get('image-upload-preview', [ImageController::class, 'index']);
Route::post('store-image', [ImageController::class, 'store']);

Generate Controller By Artisan

Now, you need to generate or create a controller file using artisan command, so use the php artisan make:controller command and generate/create a new controller file:

php artisan make:controller ImageController

In this controller file, we will create 2 methods for display file uploading form and store file into database and folder in laravel web application.

After that, go to App/Http/Controllers/ directory and find the created ImageController file and update the following code into your file:

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use Validator,Redirect,Response;
Use App\Models\Image;
 
class ImageController extends Controller
{
    public function index() {
        return view('image-preview');
    }
 
    public function store(Request $request)
    {
        request()->validate([
            'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
        ]);


         if ($files = $request->file('image')) 
         {
               $destinationPath = 'public/image/'; // upload path
               $imageName = date('YmdHis') . "." . $files->getClientOriginalExtension();
               $files->move($destinationPath, $imageName);
               $save['title'] = "$imageName";
         }
         
         $check = Image::insertGetId($save);

 
                return Redirect::to("image-upload-preview")
        ->withSuccess('Image Has been successfully uploaded.');
 
    }
}

Create Blade Views

Next, you need to create a blade views file, so go resource/views directory and create the following blade views file.

Go to resource/views/ then create a new file name image-preview.blade.php and update the following code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <meta name="csrf-token" content="{{ csrf_token() }}">

                </div>
                  
                  
                <div class="col-md-12">

        $('#image').change(function(){
          
            let reader = new FileReader();
            reader.onload = (e) => { 
              $('#display-image-preview').attr('src', e.target.result); 
            }
            reader.readAsDataURL(this.files[0]); 
 
        });

    });
 
</script>
</body>
