Hi @phatoz
If I get it right, you should provide the current date. Also, I’m sorry I forgot to remove the number “85”. It’s just a post ID for testing purpose. So, your code should be like this:
<?php
// date starting the week of loaded treasure bag
$today = date('Ymd');
$last_week = $today-6;
$next_week = $today+6;
$treasure_bag_date = get_sub_field('treasure_bag_date');
?>
<tr <?php if( ($treasure_bag_date >= $last_week) && ($treasure_bag_date <= $next_week) ){ echo "id='active_week'"; }?>>
I hope this helps 🙂
