Using the Date Picker field in a Repeater field, I’m trying to display a range of dates. The last row has the oldest date, and the first row has the latest date. You can see it partially working on my archive page – http://dev.foursquarechurch.info/sermons/. Here’s my code so far:
<?php
$rows = get_field( 'sermon_series_media' ); // Get all the rows
$first_row_date = $rows[0]['sermon_date']; // Get the first row
$last_row = end( $rows );
$last_row_date = $last_row['sermon_date']; // Get the sub field value
if( $last_row_date ) : ?>
<div class="archive-sermon-date-range">
<?php echo last_row_date; ?>
<?php if( $last_row_date != $first_row_date ) : ?> - <?php echo $first_row_date; ?>
<?php endif; ?>
</div>
<?php endif; ?>
As you can see on the Peace Makers series, I get a warning. The Peace Makers series doesn’t have any data in the Repeater field – There are no rows.
Warning: end() expects parameter 1 to be array, boolean given in…
I’m very new to PHP. Any help would be appreciated.
Only output content if there are rows
<?php
$rows = get_field( 'sermon_series_media' ); // Get all the rows
if ($rows) {
$first_row_date = $rows[0]['sermon_date']; // Get the first row
$last_row = end( $rows );
$last_row_date = $last_row['sermon_date']; // Get the sub field value
if( $last_row_date ) :
?>
<div class="archive-sermon-date-range">
<?php
echo last_row_date;
if( $last_row_date != $first_row_date ) :
?> - <?php echo $first_row_date;
php endif;
?>
</div>
<?php
endif;
} // end if $rows
That works. Thanks, John!
