File
File control lets you upload and select files using the WordPress Media Library. The control stores file information as an array.
Control Settings
- Allowed Mime Types (
allowed_mime_types) - the file types the media picker accepts. Empty by default, and an empty list allows every type WordPress allows
The field is a multi-select over the file types WordPress allows uploading, so the choices are extension groups such as jpg|jpeg|jpe, png and mp4|m4v rather than free text.
Saved Data
The control saves the following file information:
| Name | Description |
|---|---|
id | Unique ID of uploaded file |
url | URL to access the file |
alt | Optional alt attribute used in <img> tags |
title | Attachment title |
caption | Optional caption |
link | Link to file |
