ACF Datepicker issue

  • hi,
    i have an issue to count the difference in the october month.

    <?php $date_from = get_field( 'retreat_date_from' );
    $date_to = get_field( 'retreat_date_to' );
    
    $date_1 = new DateTime(date('Y-m-d', strtotime($date_from)));
    $date_2 = new DateTime(date('Y-m-d', strtotime($date_to)));
    
    $days = $date_1->diff($date_2)->days;
    ?>

    HTML
    <a href="<?php echo the_permalink(); ?>"><h3 class="uk-card-title uk-margin-remove-bottom"><?php echo $days; ?> Tage <?php the_title(); ?></h3></a>

    the october date returns 0 Tage and 1970-01-01

    var_dump($days, $date_from, $date_to, $date_1, $date_2);
    returns:
    int(0) string(10) “10 Oktober” string(15) “14 Oktober 2018” object(DateTime)#4743 (3) { [“date”]=> string(26) “1970-01-01 00:00:00.000000” [“timezone_type”]=> int(3) [“timezone”]=> string(3) “UTC” } object(DateTime)#4744 (3) { [“date”]=> string(26) “1970-01-01 00:00:00.000000” [“timezone_type”]=> int(3) [“timezone”]=> string(3) “UTC” }

    maybe someone can help me

    kind regards

  • strtotime() requires specific date formats and your fields are probably not returning the date in a format that can be used. http://php.net/manual/en/datetime.formats.date.php, looking at your return values of 10 Oktober and 14 Oktober 2018 are in any of the correct formats.

  • Hi John,

    thank you for your response. I have fixed this issue with ->

    <?php
                    $date_from  = get_field( 'retreat_date_from' );
                    $date_to    = get_field( 'retreat_date_to' );
                    $date_1     = new DateTime(date('Y-m-d', strtotime($date_from)));
                    $date_2     = new DateTime(date('Y-m-d', strtotime($date_to)));
                    $days       = $date_1->diff($date_2)->days + 1;
    
                     // var_dump($days, $date_from, $date_to, $date_1, $date_2);
                     // var_dump(strtotime(get_field('retreat_date_to')));
                  ?>
    
                  <div class="uk-card-body uk-padding-small">
                    <span class="location-card"><?php the_field('retreat_location'); ?></span>
                      <a href="<?php echo the_permalink(); ?>"><h3 class="uk-card-title uk-margin-remove-bottom"><?php echo $days; ?> Tage <?php the_title(); ?></h3></a>
                      <p class="uk-margin-remove-top"><?php echo date_i18n('j F', strtotime($date_from)); ?> - <?php echo date_i18n('j F Y', strtotime($date_to)); ?></p>
    
                    </div>
