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. |
