PHP countdown with custom field in wordpress

Question

I want to display the days remaining till the date specified in a custom field inside of wordpress. My custom field is named bewerbungs_frist . I'M using this code:

<?php $days = ceil((strtotime("<?php the_field('bewerbungsfrist'); ?>") - time())/(60*60*24));
        $s='';
        if ($days!=1) {
             $s='s';
        }
        echo $days. " days "; ?>

As a output I get something like -1500 days. That can't be right. Can somebody help me out?

I solved the issue with this code:

<p>Bewerbungsfrist: <?php $date = DateTime::createFromFormat('Ymd', get_field('bewerbungs_frist'));  echo $date->format('d.m.Y');?></p>
noch <?php $days = ceil((strtotime(get_field('bewerbungs_frist')) - time())/(60*60*24));
echo $days. " Tage "; ?>

Answer 1

You are opening wrong php tags between already opened tags

try this

$days = ceil((strtotime(the_field('bewerbungsfrist')) - time())/(60*60*24));
