VIDEO: How to upload a PDF (or any file) to a Joomla site and then link to it in an article or module using JCE. Richard Pearce on Monday, 24 November 2014 16:28. The maximum file upload size is determined by a setting at your host. Dec 26, 2017 - Pdf File Upload In Joomla Modules.

Please please please make sure you use the filtering available in the MediaHelper. Specifically never trust uploaded images, always check first that they are valid file types, then that they are in the list of approved types of files listed in your global configuration, that the names do not contain html or javascript, and that the files themselves do not contain code.
In particular I would recommend the MediaHelper::canUpload method which will check the majority of these things for you. If anything you should be checking even more strongly. Also make sure that you are checking whether the user has permission to upload. If anything you should make the checking even more restrictive. Use the APIs that joomla gives you, such as the built in media field.
