Woocommerce replace fragments in a number of divs [closed]

I am utilizing the next code to show totally different picture primarily based on the situation whether or not the cart is empty or not.

add_filter( 'woocommerce_add_to_cart_fragments', 'custom_happy_sad_thumb' );
operate custom_happy_sad_thumb( $fragments ) {
 
    ob_start();
    
    $cart_count = WC()->cart->cart_contents_count;
    
    ?>
    <div class="sad">
        <?php
        if ( $cart_count > 0 ) { ?>
            <img src="<?php echo get_stylesheet_directory_uri(); ?>/assets/img/happy.png" alt="">
        <?php }
        else { ?>
            <img src="<?php echo get_stylesheet_directory_uri(); ?>/assets/img/sad.png" alt="">
        <?php } ?>
    </div>
    <?php
 
    $fragments['.sad'] = ob_get_clean();
    return $fragments;
}

Now, I wish to have comparable performance within the footer additionally, the one distinction is there the div class title is ‘footer-left’, so would I have to rewrite this code once more in features.php? or can I simply add the category title in $fragments array? Like this: $fragments[‘.sad’, ‘footer-left’]

Thanks upfront.
