Download the PHP package sands/uploadable without Composer

Uploader Trait for Laravel Models

This package is to simplify upload handling in a Laravel application. Should work for both Laravel 5 and Lumen.

Key features:

1. Simple to use
2. Extendable
3. Handles both single and multiple uploads

Core Concepts

1. All uploads belongs to a record in the database
2. File upload handling, manipulation and saving are done by passing it through a set of filters in series (à la gulp).
3. You can create your own filters.

Installation

1. Install it in your application: composer require sands/uploadable
2. Add Sands\Uploadable\UploadableServiceProvider::class into your app/config/app.php file, inside the providers array.
3. Publish the package's migration: php artisan vendor:publish.
4. Run php artisan migrate to create the uploads table.

Usage

Use the UploadableTrait trait inside your model

Add a $uploadableConfig array property inside your model file:

In the model's boot method, listen for saved and deleted events to attach and detach files to the model:

Whenever the model is saved, this package will look for any matching uploadableConfig with the request. If there are any, the uploaded file will be passed through the configured filter. Each t

Getting Uploads Related to a Model

Relationship between a model and uploads are implemented with the simple Laravel's morphMany method. You can access the files simply by $task->uploads. This will return all files and their mutations related to a model.

To filter through the files related to a model you can simply do $task->uploads()->where() ....

There is also a shorthand files($type = null, $prefix = null) method that takes $type argument where it filters the type of file uploaded (images in the above example) and $prefix argument where it will search for uploads with the prefix. This method will return an Eloquent query so you can further refine the search.

The upload object properties are as per below:

Example for getting an uploaded image's URL:

Creating Your Own Filter

It is very easy to create your own filter:

1. Create a class that implements Sands\Uploadable\FilterInterface.
2. Register the filter: app('uploadable')->registerFilter('filterName', 'filterClass').
3. There is no step 3.

For example, lets say that we want to rotate all uploaded images by a certain configurable degrees:

Create a RotateImage class:

Register the filter:

Use it in your model:

Thats it!
