You can learn composer through the following address:

File upload and management is a common but complex task when developing a Laravel project. Users may upload various types of files and images that need to be verified, stored and processed. Especially for images, we may need to generate versions of different resolutions for use in different scenarios. How to handle these requirements efficiently has become a problem in my development process.

After trying several methods, I found a library called aldozumaran/uploader which can be easily integrated into a Laravel project via Composer. This library provides powerful file upload and management functions, able to handle image storage and file verification at different resolutions, greatly simplifying my workflow.

Installation and configuration

To use the aldozumaran/uploader library, you need to install it through Composer first. Open your composer.json file and add the following dependencies:

 <code>"aldozumaran/uploader": "dev-master"</code>

Then run the following command:

 <code>composer update</code>

After the installation is completed, you need to add the service provider and alias in the config/app.php file:

 <code class="php">'providers' => [ AldoZumaran\Uploader\UploaderServiceProvider::class, ], 'aliases' => [ 'Uploader' => AldoZumaran\Uploader\Facades\Uploader::class, ],</code>

Finally, run the following command to publish the configuration file:

 <code>php artisan vendor:publish</code>

Configuration File

The configuration file config/uploader.php allows you to customize various settings such as file size, valid extensions, and upload directories. Here is a sample configuration:

 <code class="php">return [ 'sizes' => [ 'thumb' => [ 'width' => 150, 'height' => 150, ], 'medium' => [ 'width' => 600, 'height' => 450 ], // 你可以添加更多的尺寸], 'valid' => [ 'files' => ['pdf','doc','docx','odt', 'jpg', 'png', 'jpeg'], 'images' => ['jpg','jpeg','png'] ], 'upload_dir' => 'uploads', 'files_dir' => 'files', 'images_dir' => 'images', 'range' => 1000, ];</code>

How to use

Using the aldozumaran/uploader library, you can easily upload files and images and generate image versions with different resolutions. Here is a sample code for how to save a file:

 <code class="php">Route::post('curriculum', function(){ // Form Input:<input name="file" type="file"> $id = \DB::table('curriculums')->count(); // 1540 $file = Uploader::save("file", "curriculum", 1540); // File saved in public/uploads/files/curriculum/1000/XXXXX_XXXXXXXXXXXXXXXXX.pdf echo $file; // XXXXX_XXXXXXXXXXXXXXXXX.pdf }); Route::post('avatar', function(){ // Form Input:<input name="avatar" type="file"> $id = \DB::table('avatars')->count(); // 39 $file = Uploader::save("avatar", "avatars", 39, false, ['jpg']); // upload only jpg files // Images saved in // public/uploads/images/thumb/avatars/0/XXXXX_XXXXXXXXXXXXXXXXX.jpg // 500x150 // public/uploads/images/medium/avatars/0/XXXXX_XXXXXXXXXXXXXXXXX.jpg // 1000x300 // public/uploads/images/original/avatars/0/XXXXX_XXXXXXXXXXXXXXXXX.jpg // 1000x300 echo $file; // XXXXX_XXXXXXXXXXXXXXXXX.jpg });</code>

You can also use the getUrl method to get the URL of the file:

 <code class="php">Route::get('avatar', function(){ $file = Uploader::getUrl(39, 'avatars', 'XXXXX_XXXXXXXXXXXXXXXXX.jpg', false, 'thumb'); echo $file; // http://example.com/uploads/images/thumb/avatars/0/XXXXX_XXXXXXXXXXXXXXXXX.jpg });</code>
