在woocommerce产品中包装iframe

So I have some code that I tested and it works for a regular page/post in my functions.php

function div_wrapper($content) {

    static $foo_called = false;
if ($foo_called) return;

$foo_called = true;


//echo "here";

$pattern = '~<iframe.*</iframe>~';
preg_match_all($pattern, $content, $matches);

foreach ($matches[0] as $match) {
    // wrap matched iframe with div
    $wrappedframe = '<div class="iframe-container">' . $match . '</div>';

    //replace original iframe with new in content
    $content = str_replace($match, $wrappedframe, $content);

    echo $content;

}

return $content;
}

add_filter('the_content', 'div_wrapper', 98 );

So all of my iframes are on woocommerce product pages. The filter hook "the_content" seems to not be affecting the woocommerce product pages. I have tried using different hooks and actions and tried using woocommerce hooks/actions and still, I can never get this code to run and work on the iframes I need. Any help or guidance would be greatly appreciated.
