Hi,
I am new to the pligg platform, and would be glad if expert programmers in this forum could help me out. Well, I am trying to read the $url in link_summary.tpl, and extract an id argument from it. However, i think $url in link_summary.tpl is a "pliig" avriable and thus the assignment to $video_url below is posing a problem.

Here is my snippet.

{php}
$video_url=$url; // should assign the {$url} argument to $video_url
// the above code gives an error. I need help assigning this url argument to $video_url

echo $video_id; // prints the
{/php}

Will be really grateful if people could help me solve this "variable assignment" problem.
Yours sincerely,
Abhinav
