1URI.SafeIframeRegexp\r
2TYPE: string/null\r
3VERSION: 4.4.0\r
4DEFAULT: NULL\r
5--DESCRIPTION--\r
6<p>\r
7 A PCRE regular expression that will be matched against an iframe URI. This is\r
8 a relatively inflexible scheme, but works well enough for the most common\r
9 use-case of iframes: embedded video. This directive only has an effect if\r
10 %HTML.SafeIframe is enabled. Here are some example values:\r
11</p>\r
12<ul>\r
13 <li><code>%^http://www.youtube.com/embed/%</code> - Allow YouTube videos</li>\r
14 <li><code>%^http://player.vimeo.com/video/%</code> - Allow Vimeo videos</li>\r
15 <li><code>%^http://(www.youtube.com/embed/|player.vimeo.com/video/)%</code> - Allow both</li>\r
16</ul>\r
17<p>\r
18 Note that this directive does not give you enough granularity to, say, disable\r
19 all <code>autoplay</code> videos. Pipe up on the HTML Purifier forums if this\r
20 is a capability you want.\r
