Question 166431 in Wordpress Question posted in
The official Wordpress documentation can be found here.

“Add class to P if it contains iframe”–how is this done in function.php (WordPress)?

I have this code:

<p>
<iframe src=""></iframe>
</p>

How can I add a class to the P using function.php? only in a single post?

so the result will be:

<p class="something">
 <iframe src=""></iframe>
</p>

    Since you haven’t given us much of an explanation of where your HTML is coming, I’ll just have to guess at a bunch of things. The code below will output the requested HTML on a single post.

    if (get_queried_object_id() === 123) {
    echo '<p class="something"><iframe src=""></iframe></p>';
}

    Check if your p tag has children using jQuery:

    // Add some class that is unique or someting
if ( $('p.unique-class').children().length > 0 ) {
     // do something
     $(this).addClass('your-class');
}

// or

if ( $('p.unique-class').find('iframe').length > 0 ) {
    // do something
     $('p.unique-class').addClass('your-class');
}
