Edit File: URI.SafeIframeRegexp.txt
URI.SafeIframeRegexp TYPE: string/null VERSION: 4.4.0 DEFAULT: NULL --DESCRIPTION-- <p> A PCRE regular expression that will be matched against an iframe URI. This is a relatively inflexible scheme, but works well enough for the most common use-case of iframes: embedded video. This directive only has an effect if %HTML.SafeIframe is enabled. Here are some example values: </p> <ul> <li><code>%^http://www.youtube.com/embed/%</code> - Allow YouTube videos</li> <li><code>%^http://player.vimeo.com/video/%</code> - Allow Vimeo videos</li> <li><code>%^http://(www.youtube.com/embed/|player.vimeo.com/video/)%</code> - Allow both</li> </ul> <p> Note that this directive does not give you enough granularity to, say, disable all <code>autoplay</code> videos. Pipe up on the HTML Purifier forums if this is a capability you want. </p> --# vim: et sw=4 sts=4
