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.
