Download the PHP package trntv/yii2-file-kit without Composer

This kit is designed to automate routine processes of uploading files, their saving and storage. It includes:

• File upload widget (based on Blueimp File Upload)
• Component for storing files (built on top of flysystem)
• Actions to download, delete, and view (download) files
• Behavior for saving files in the model and delete files when you delete a model

Here you can see list of available filesystem adapters

Installation

The preferred way to install this extension is through composer.

or add

to the require section of your composer.json file.

File Storage

To work with the File Kit you need to configure FileStorage first. This component is a layer of abstraction over the filesystem

• Its main task to take on the generation of a unique name for each file and trigger corresponding events.

There are several ways to configure trntv\filekit\Storage to work with flysystem.

Using Closure

Using filesystem builder

• Create a builder class that implements trntv\filekit\filesystem\FilesystemBuilderInterface and implement method build which returns filesystem object. See examples/
• Add to your configuration:

Read more about flysystem at http://flysystem.thephpleague.com/

Using third-party extensions

• Create filesystem component (example uses creocoder/yii2-flysystem)

• Set filesystem component name in storage configuration:
