Joomla file Form Field Type

It provides an input field for files. When using the file input type, you should always add the attribute enctype="multipart/form-data" to your form tag. Otherwise, the uploaded files will not be attached correctly.

Example XML field definition:

<field name="myfile"
description="Choose an image with maximum 100KB"
accept="image/*" />

Additional Parameters

accept: It tells the browser what MIME types your form will allow to be uploaded.

multiple: It allows you to upload multiple files at once when set to multiple="true".
