Laravel 10 Intervention Image Upload Tutorial

Introduction

Intervention Image is a PHP image handling and manipulation library that provides an easier and expressive way to create, edit, and compose images. It is an open source library and it is available on GitHub.

In this tutorial, we will learn how to upload images in Laravel 10 using Intervention Image library. We will also learn how to resize and crop images before uploading them.

Prerequisites

Before starting this tutorial, you should have a basic understanding of the following:

Laravel 10

HTML

CSS

PHP

Step 1 – Install Intervention Image Library

First, we need to install the Intervention Image library. We can do this using Composer.

Run the following command in the terminal to install the library:

composer require intervention/image

Step 2 – Create a Model and Migration

Next, we need to create a model and migration for our images. We can do this using the Artisan command line tool.

Run the following command in the terminal to create a model and migration:

php artisan make:model Image -m

This will create a model and migration file for our images.

Step 3 – Configure the Database

Next, we need to configure the database. Open the migration file and add the following code:

public function up()
{
Schema::create(‘images’, function (Blueprint $table) {
$table->id();
$table->string(‘name’);
$table->string(‘path’);
$table->timestamps();
});
}

This will create a table in the database with the name “images”.

Step 4 – Create a Form

Next, we need to create a form for uploading images. We can do this by creating a view file and adding the following code:

This will create a form with a file input field and a submit button.

Step 5 – Create a Controller

Next, we need to create a controller for handling the image upload. We can do this using the Artisan command line tool.

Run the following command in the terminal to create a controller:

php artisan make:controller ImageController

This will create a controller file for our images.

Step 6 – Configure the Controller

Next, we need to configure the controller. Open the controller file and add the following code:

public function upload(Request $request)
{
// Validate the request
$request->validate([
‘image’ => ‘required|image|mimes:jpeg,png,jpg,gif,svg|max:2048’,
]);

// Get the image
$image = $request->file(‘image’);

// Generate a new filename.
$filename = time() . ‘.’ . $image->getClientOriginalExtension();

// Save the image
$path = $image->storeAs(‘images’, $filename);

// Create a new image record in the database
$image = Image::create([
‘name’ => $filename,
‘path’ => $path,
]);

// Return the response
return response()->json([
‘message’ => ‘Image uploaded successfully’,
‘image’ => $image
]);
}

This will create a controller action for handling the image upload.

Step 7 – Resize and Crop the Image

Next, we need to resize and crop the image before uploading it. We can do this using the Intervention Image library.

Add the following code to the controller action:

// Resize and crop the image
$img = Image::make($image->getRealPath());
$img->fit(300, 300, function ($constraint) {
$constraint->upsize();
});

// Save the image
$img->save($path);

This will resize and crop the image before uploading it.

Step 8 – Register the Route

Finally, we need to register the route for the controller action. Open the routes/web.php file and add the following code:

Route::post(‘image/upload’, ‘ImageController@upload’)->name(‘image.upload’);

This will register the route for the controller action.

Conclusion

In this tutorial, we have learned how to upload images in Laravel 10 using Intervention Image library. We have also learned how to resize and crop images before uploading them.
