Sort events by date

Hi,

I’ve been using ACF for a long time now, awesome, but I’m stuck.

I added dates to some posts, but now I want to sort them using the date. I can manage that, but I need something else…
I want to display a div displaying the date every time a new date is occurring in the posts.

Something like this:

<?php 
if (have_posts()) : while(have_posts()) : the_post();
  $acf_date = the_field('event_date');
  if ($acf_date == 'FIRST TIME BEING DISPLAYED'){ ?>
<div><?php echo $acf_date; ?><?div>
<?php } endwhile; endif; ?>

To clear things up, I added an image of my idea. Each time there is a new date, a blue square with the date will be displayed.

I hope this is clear, otherwise I will try to explain it a bit further.

Thanks in advance,
Alex

Hi @alexnl88

Hmm… May be you could have an array that records the date field’s values then use in_array() PHP function to check if the array contains some the date value if not, then add it. The code would look something like this:

<?php 
$dates = array();
if (have_posts()) : while(have_posts()) : the_post();
  $acf_date = the_field('event_date');
  if ( !in_array($acf_date, $dates) ){ ?>
<div><?php echo $acf_date; array_push($dates, $acf_date); ?><?div>
<?php } endwhile; endif; ?>
