Making a YouTube video auto-play only the first time a user visits

Hi,

I have embeded a YouTube video in the sidebar of my blog (podcast). I want it to auto play ONLY the first time they visit, then have it be click-to-play on subsequent visits. Currently, if they surf around, the video starts playing each time they access a blog post.

I found some code that is supposed to work, but when I add a text widget and the corresponding php below, it doesn’t seem to recognize it. Instead, you see two instances of the video, one which auto play and another that is click to play. I have also added the other code to the header as instructed.

For now, I’ve deleted the php in the text widget so it only appears once. Hoping we can get this resolved.

Any suggestions?

Thanks

==============================================

Place this at the very top of header.php

==============================================

<?php
$value = “1”;
// send a cookie that expires in 1 year
setcookie(“video_viewed”,$value, time()+60*60*24*30*12);
?>

==============================================

Place this at the appropriate position within your Template. Be sure you have the “autoplay” and “non-autoplay” versions of your video player ready.

==============================================

<?php
// If Cookie is set
if ($_COOKIE[“video_viewed”] == “1”) {
?>
INSERTNONAUTOPLAYVIDEOCODEHERE
<?php
} else { ?>
INSERTAUTOPLAYVIDEOCODEHERE
<?php }
// End Conditional Region
?>
