PHP. If Cookie exists do this - Else do that

Question

I'm trying to create a little php function, which if a cookie exists, then use the css styles, else if it does not exist use these.

I'm using the code below, but it is using the if styles regardless if the cookie exists or not.

What am i doing wrong?

<?php if ( isset($_COOKIE['CookieLawInfoConsent']) ) : ?>
<style>
    html.has-not-scrolled #desktop-header { top: 0px; }
    #mobile-header { top: 0px; }
    main {top: 0px;}
</style>
<?php else : ?>
<style>
    @media all and (min-width: 1201px) and (max-width: 1235px) {
       html.has-not-scrolled #desktop-header { top: 80px; }
    #mobile-header { top: 80px; }
    main {top: 80px;
}
</style>
<?php endif; ?>

`var_dump($_COOKIE['CookieLawInfoConsent'])` and look at what's in it before the if statement. That should give you a good indication why it keeps hitting the if part of the block. You've likely set that variable elsewhere in your code. — DiddleDot, Aug 27 '21 at 20:32

You can use an html class that is unique set_not_cookie or set_cookie based on cookie input:

<div class="<?php if ( isset($_COOKIE['CookieLawInfoConsent']) ) : ?> 
set_cookie 
<?php else : ?> 
set_not_cookie <?php endif; ?>">
