Modifying YouTube Video Display in WordPress

WordPress automatically handles YouTube links, which can be very helpful. However, this means you are stuck with whatever WordPress has configured, so if you want to customize how the videos are displayed – like eliminating the related video previews that display at the end of the video – you are out of luck…at least until you install this plugin.

The “Hide YouTube Related Videos” plugin by SparkWeb Interactive, Inc. will allow you to hide the related videos that display at the end. It’s simple to install (you can do so through the admin panel). After installing, just make sure to activate it, and there is nothing else to configure. It just works after you install it.

If you are not seeing the change after installing the plugin, make sure you clear the cache or do a forced refresh on the page to make sure you are getting a new copy of the content.

There is also a hyrv_extra_querystring_parameters filter which allows you to add additional parameters to the YouTube URL. To add additional parameters to your YouTube call, click on “Plugins” and then on “Editor” in the left-hand menu bar in the WordPress admin panel. In the upper-right corner of the screen, choose “Hide YouTube Related Videos” and click “Select”.

A list of files will now be displayed on the right. Click on “hide-youtube-related-videos/hide-youtube-related-videos.php”. You’ll need to scroll down through a bit of comments, and then you’ll see a the function hide_youtube_related_videos. You can add your additional parameters to $data. Make sure to include the HTML entity code for an ampersand to the end of it.

Here is an example where I added a color parameter to change the status bar (where it shows how much of the video you have watched) from red to white. I go in and change:

apply_filters("hyrv_extra_querystring_parameters", "wmode=transparent&")

to:

apply_filters("hyrv_extra_querystring_parameters", "wmode=transparent&color=white&")

Here is the full original code:

add_filter( 'oembed_result', 'hide_youtube_related_videos', 10, 3);
function hide_youtube_related_videos($data, $url, $args = array()) {
    $data = preg_replace('/(youtube\.com.*)(\?feature=oembed)(.*)/', '$1?' . apply_filters("hyrv_extra_querystring_parameters", "wmode=transparent&") . 'rel=0$3', $data);
    return $data;
}

And the full updated code:

add_filter( 'oembed_result', 'hide_youtube_related_videos', 10, 3);
 function hide_youtube_related_videos($data, $url, $args = array()) {
 $data = preg_replace('/(youtube\.com.*)(\?feature=oembed)(.*)/', '$1?' . apply_filters("hyrv_extra_querystring_parameters", "wmode=transparent&color=white&") . 'rel=0$3', $data);
 return $data;
 }

There are many parameters that you can add to modify the way the YouTube video displays and acts. You can view the full list of available parameters on the Google Developers website:
