Laravel Image Intervention

Published 1 year ago

👋 Welcome fellow I have used the intervention/image package to resize the image and then save the image into the database. We generally have the use cases like upload an avatar or upload a product image of a specific size on an e-commerce website. So intervention/image package is used to upload and resize the images.

Step 1: Install Laravel Project

We install the laravel project by typing the following command.

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

Step 2: Set up a MySQL database

Now, configure this database in the .env file.

//.env

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

I have set up local database credentials.

Next, migrate two tables provided by Laravel 7 Move to your terminal and hit the following command.

php artisan migrate

It will establish three tables in your database.

  1. users
  2. password_resets
  3. failed_jobs

Step 3: Construct a model and migration file for our image_model table

Type the following command in your terminal.

php artisan make:model ImageModel -m

It will create two files.

  1. ImageModel.php model.
  2. create__image_models_table migration file.

We need to create a Schema for the passports table. So navigate to Laravel  >>  database  >>  migrations  >>  create__image_models_table.

//create__image_models_table

/**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('image_models', function (Blueprint $table) {
            $table->increments('id');
            $table->string('filename');
            $table->timestamps();
        });
    }

Step 4: Build a view file to add the image in the database

Create a file in the resources  >>  views  >>   createimage.blade.php and put the following code in it.

//createimage.blade.php

<html lang="en">
<head>
  <title>Laravel  Image Intervention</title>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
</head>
<body>
  
  <div class="container">
    <h3 class="jumbotron">Laravel  Image Intervention </h3>
    <form method="post" action="{{url('create')}}" enctype="multipart/form-data">
        @csrf
        <div class="row">
          <div class="col-md-4"></div>
          <div class="form-group col-md-4">
          <input type="file" name="filename" class="form-control">
          </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-top:10px">Upload Image</button>
          </div>
        </div>     
  </form>
  </div>
</body>
</html>

Step 5: Create one controller and route

php artisan make:controller ImageController --resource

It will create one controller file called ImageController.php

we register route in routes  >>  web.php file. So let us do it.

//web.php

Route::get('create','ImageController@create');
Route::post('create','ImageController@store');

The next step would be to go to ImageController.php file and add into the create() function some code.

// ImageController.php

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

After that, we require the beginning Laravel Development server. So in the terminal, follow the following command.

php artisan serve

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

Step 6: Install Intervention Image Package

Move to your terminal type following command.

composer require intervention/image

Find the providers in config >> app.php file and register the ImageServiceProvider.

'providers' => [
        // ...
        'Intervention\Image\ImageServiceProvider',
    ]

Locate the aliases in config >> app.php file and register the aliases.

'aliases' => [
        // ...
        'Image' => 'Intervention\Image\Facades\Image',
    ]

By default, the Intervention Image uses PHP’s GD library extension to process all images. If you want to switch to Imagick, you can pull a configuration file into your application by running one of the following artisan command.

php artisan vendor:publish --provider="Intervention\Image\ImageServiceProviderLaravelRecent"

In recent Laravel applications, the configuration file is copied to, config/image.php in older Laravel 4 applications you will find the file at app/config/packages/intervention/image/config.php.

With this copy, you can alter the image driver settings for you application locally.

Step 7: Save Data into the Database.

We require coding the store function in sequence to store the data in the database. We can do it programmatically to create the two folders, but let us manually create two folders in the public directory called images and thumbnail.

//ImageController.php

use App\ImageModel;
use Image;

public function store(Request $request)
    {
       
        $originalImage= $request->file('filename');
        $thumbnailImage = Image::make($originalImage);
        $thumbnailPath = public_path().'/thumbnail/';
        $originalPath = public_path().'/images/';
        $thumbnailImage->save($originalPath.time().$originalImage->getClientOriginalName());
        $thumbnailImage->resize(150,150);
        $thumbnailImage->save($thumbnailPath.time().$originalImage->getClientOriginalName()); 

        $imagemodel= new ImageModel();
        $imagemodel->filename=time().$originalImage->getClientOriginalName();
        $imagemodel->save();

        return back()->with('success', 'Your images has been successfully Upload');

    }

Step 8: Define Validation for Image

Add validation in Store function.

//ImageController.php

public function store(Request $request)
    {
        $this->validate($request, [
            'filename' => 'image|required|mimes:jpeg,png,jpg,gif,svg'
         ]);
    }

If any validation, Fail it through error.

Next, we pass an image to the blade file, which we can display images.

//ImageController.php

public function create()
    {
        $image = ImageModel::latest()->first();
        return view('createimage', compact('image'));
    }

The final Code of Controller looks like below.

//ImageController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\ImageModel;
use Image;

class ImageController extends Controller
{

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        $image = ImageModel::latest()->first();
        return view('createimage', compact('image'));
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $this->validate($request, [
            'filename' => 'image|required|mimes:jpeg,png,jpg,gif,svg'
         ]);
        $originalImage= $request->file('filename');
        $thumbnailImage = Image::make($originalImage);
        $thumbnailPath = public_path().'/thumbnail/';
        $originalPath = public_path().'/images/';
        $thumbnailImage->save($originalPath.time().$originalImage->getClientOriginalName());
        $thumbnailImage->resize(150,150);
        $thumbnailImage->save($thumbnailPath.time().$originalImage->getClientOriginalName()); 

        $imagemodel= new ImageModel();
        $imagemodel->filename=time().$originalImage->getClientOriginalName();
        $imagemodel->save();

        return back()->with('success', 'Your images has been successfully Upload');

    }

}

Step 9: Modify View File

We can display an image in the view file, so add some code in view file for the display image.

//createimage.blade.php

       @if($image)
   	    <div class="row">
         <div class="col-md-8">
              <strong>Original Image:</strong>
              <br/>
              <img src="/images/{{$image->filename}}" />
        </div>
        <div class="col-md-4">
            <strong>Thumbnail Image:</strong>
            <br/>
            <img src="/thumbnail/{{$image->filename}}"  />
       	 </div>
   		</div>
        @endif


The final Code of View file looks like below.

//createimage.blade.php

<html lang="en">
<head>
  <title>Laravel  Image Intervention</title>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.js"></script>
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
</head>
<body>
  
  <div class="container">
  @if(session('success'))
        <div class="alert alert-success">
          {{ session('success') }}
        </div> 
        @endif
        @if (count($errors) > 0)
      <div class="alert alert-danger">
        <strong>Whoops!</strong> There were some problems with your input.<br><br>
        <ul>
          @foreach ($errors->all() as $error)
              <li>{{ $error }}</li>
          @endforeach
        </ul>
      </div>
      @endif
    <h3 class="jumbotron">Laravel  Image Intervention </h3>
  <form method="post" action="{{url('create')}}" enctype="multipart/form-data">
        @csrf
        <div class="row">
          <div class="col-md-4"></div>
          <div class="form-group col-md-4">
          <input type="file" name="filename" class="form-control">
          </div>
        </div>
        <div class="row">
          <div class="col-md-4"></div>
          <div class="form-group col-md-4">
          <button type="submit" class="btn btn-success" style="margin-top:10px">Upload Image</button>
          </div>
        </div>
        @if($image)
   	    <div class="row">
         <div class="col-md-8">
              <strong>Original Image:</strong>
              <br/>
              <img src="/images/{{$image->filename}}" />
        </div>
        <div class="col-md-4">
            <strong>Thumbnail Image:</strong>
            <br/>
            <img src="/thumbnail/{{$image->filename}}"  />
       	 </div>
   		</div>
        @endif       
  </form>
  </div>
</body>
</html>
