[Plugin: Smart YouTube PRO] YouTube Link & Shortcodes

Hi,

the regular expression for parsing the YouTube Link (smartyoutube.php line 670) does not handle a YouTube link within a shortcode correctly. Might also affect Metacafe, Vimeo, etc. links but I didn’t test it.

Example:

[toggle]http://www.youtube.com/watch?v=someid[/toggle] results in ‘[/toggle]’ in $match[7] which ends up in $time in tag_youtube().

[toggle]http://www.youtube.com/watch?v=someid [/toggle] works.

See regexp explain: http://pastebin.com/de1DxtSq

===
( group and capture to \7:
———————————————————————-
[^<\s]* any character except: ‘<‘, whitespace
(\n, \r, \t, \f, and ” “) (0 or more
times (matching the most amount
possible))
———————————————————————-
) end of \7
===

‘[‘ should be part of the exception character set.

Fix:
