REDCap Module - File Type Enforcement
PHPJavaScript
An external module I developed for REDCap, a web application for building and managing online surveys and databases that is used by over 8,300 active institutions in 160+ countries.
Having built several REDCap webforms for use at the GW School of Medicine & Health Sciences, I observed that there is no native way to strictly enforce types for uploaded files. To remedy this, I developed an opt-in module that allows form builders to easily restrict file uploads so that end-users can only submit permitted file types.
The module was accepted by the Vanderbilt REDCap team in May 2026 and is available for use.
