Standard Youtube Embed Code: 

<iframe width="560" height="315" src="https://www.youtube.com/embed/uxpDa-c-4Mc" frameborder="0" allowfullscreen></iframe>

Converted Format: 

<iframe width="560" height="315" src="https://www.youtube.com/embed/uxpDa-c-4Mc?enablejsapi=1&html5=1" frameborder="0" allowfullscreen id="video"></iframe>

Simply, I want to add ?enablejsapi=1&html5=1 to end of URL and add id=”video”.

How can i obtain this iframe code by manipulating the parameter $embed?

Tnx.

  1. This will add the extra params to the source. (Replace with your current print($embed) code.

    // use preg_match to find iframe src
preg_match('/src="(.+?)"/', $embed, $matches);
$src = $matches[1];

// add extra params to iframe src
$params = array(
    'enablejsapi'=> 1,
    'html5' => 1
);

$new_src = add_query_arg($params, $src);
$embed = str_replace($src, $new_src, $embed);
$embed = str_replace('></iframe>', ' ' . $attributes . '></iframe>', $embed);

print($embed);
