The code below is the main part of a function in my functions.php which returns a div
and script
which ultimately output a youtube API iframe to the template where the code had been called from. At the moment it’s working fine; however I would like to enqueue the javascript, or at least move it out of my PHP code. I tired moving it to my main JavaScript file ( which is enqueued in the footer ) but it doesn’t work when I move it there. Edit: I had hardcoded the vars to avoid having to use wp_localize_script
so as to out of the picture.
Surely there’s a better way ( or WordPress way ) of doing this?
$return = '
<div id="' . $postid . 'player"></div>
<script> var tag = document.createElement("script"); tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName("script")[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player("'. $postid .'player", {
height: "315",
width: "560",
videoId: "'. $videoID .'",
});
}
</script>
';
return $return;

First, make sure the YT api is enqueued()
and added to the footer.
function wp_enqueue_scripts__youtube_api() {
wp_enqueue_script( 'yt-player-api', 'http://www.youtube.com/player_api', array(), false, true );
}
add_action( 'wp_enqueue_scripts', 'wp_enqueue_scripts__youtube_api' );
Next, output your div somewhere on the page.
<div id="' . $postid . 'player"></div>
Then, hook into wp_footer
and make sure you set the priority higher that 20
. By then the script should be rendered on the page and you can double check with wp_script_is()
.
function wp_footer__youtube_api() {
if ( wp_script_is( 'yt-player-api', 'done' ) ) {
$postid = 123;
$videoID = 123;
?>
<script id="yt-player-api-ready" type="text/javascript">
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player("<?php echo $postid; ?>player", {
height: "315",
width: "560",
videoId: "<?php echo $videoID ?>"
});
}
</script>
<?php
}
}
add_action( 'wp_footer', 'wp_footer__youtube_api', 20 );
