correct syntax to echo variable inside iframe

Question

I know i am missing something simple. I just want to display this iframe if $video-code exists. Can anyone see what is wrong with this? working in wordpress. error is on the echo line. i've also tried adding .'$video-code'. into the url.

it is displaying the iframe correctly, but the variable is displaying as text in the url. if i call the variable elsewhere in the page without the If statement, it displays correctly.

THANKS for any help!

<?php
$key = 'video-code';
$themeta = get_post_meta($post->ID, $key, TRUE);
if($themeta != '') {
echo '<iframe id="player" width="560" height="315" frameborder="2"     src="http://www.youtube.com/embed/$video-code" ></iframe>';
}?>

your variable is $key not $video-code, so it should be '.$key.' as php variables are not parsed inside single quotes. — Sean

You can concatenate your $key, like so:

echo '<iframe id="player" width="560" height="315" frameborder="2" 
src="http://www.youtube.com/embed/' . $key . '" ></iframe>';

Where are getting the ID for the video? You need to pass the ID to $key variable. Also, you're using $door-time inside your iframe code. It should be $key. (I tested this before posting and it did actually work. Here's an example: codepad.org/rfxcmNss)
