Laminas\Form\Element\File represents a form file input and provides a default input specification with a type of FileInput (important for handling validators and filters correctly). It is intended for use with the FormFile view helper.

Basic Usage

This element automatically adds a type attribute of value file. It will also set the form's enctype to multipart/form-data during $form->prepare().

use Laminas\Form\Element;
use Laminas\Form\Form;

// Single file upload:
$file = new Element\File('file');
$file->setLabel('Single file input');

// HTML5 multiple file upload:
$multiFile = new Element\File('multi-file');
$multiFile->setLabel('Multi file input');
$multiFile->setAttribute('multiple', true);

$form = new Form('my-file');
