Upload Plugin Interfaces

For advanced usage of the upload plugin, you will need to implement one or more of the followng interfaces.

ProcessorInterface

Fully-namespaced class name: Josegonzalez\Upload\File\Path\ProcessorInterface

This interface is used to create a class that knows how to build paths for a given file upload. Other than the constructor, it contains two methods:

  • basepath: Returns the basepath for the current field/data combination
  • filename: Returns the filename for the current field/data combination

Refer to Josegonzalez\Upload\File\Path\DefaultProcessor for more details.

TransformerInterface

Fully-namespaced class name: Josegonzalez\Upload\File\Transformer\TransformerInterface

This interface is used to transform the uploaded file into one or more files that will be written somewhere to disk. This can be useful in cases where you may wish to use an external library to extract thumbnails or create PDF previews. The previous image manipulation functionality should be created at this layer.

Other than the constructor, it contains one method:

  • transform: Returns an array of key/value pairs, where the key is a file on disk and the value is the name of the output file. This can be used for properly naming uploaded/created files.

Refer to Josegonzalez\Upload\File\Transformer\DefaultTransformer for more details. You may also wish to look at Josegonzalez\Upload\File\Transformer\SlugTransformer as an alternative.

WriterInterface

Fully-namespaced class name: Josegonzalez\Upload\File\Writer\WriterInterface

This interface is used to actually write files to disk. It writes files to disk using the Flysystem library, and defaults to local storage by default. Implement this interface if you want to customize the file writing process.

Other than the constructor, it contains one methods:

  • write: Writes a set of files to an output.

Refer to Josegonzalez\Upload\File\Writer\DefaultWriter for more details.
