The EmbedPDF extension adds the <pdf> tag for embedding PDF files. It supports remote and local (uploaded to MediaWiki) files.

[edit] Installation

  1. Copy EmbedPDF.php to the new file EmbedPDF.php in your MediaWiki extensions directory.
  2. Enable the extension by adding this line to the bottom of your LocalSettings.php:
require_once('extensions/EmbedPDF.php');

[edit] Usage

  • <pdf>http://some.site.com/with/a/document.pdf</pdf>
  • <pdf>Your_uploaded_document.pdf</pdf>

[edit] Options

There are no options yet. EmbedPDF will create HTML <object> with predefined width (700 px) and height (600 px). That's all.
