ACF put a comma after the last repeater field value

I’ve the following code

<?php if(have_rows('ore')):?>

        <?php while( have_rows('ore')): the_row();

                $start = get_sub_field('start');
                $end = get_sub_field('end');
        ?>

         <?php if( get_row_index() != 1 ){ echo '/'; }?>
               <?php echo $start;?> – <?php echo $end;?>    
    
    <?php endwhile;?>
<?php endif;?>

Which outputs the two fields (“start” & “end”) in this form: 12.00 – 13.00.
In case there are more than one, they’ll be displayed like this 12.00 – 13.00 / 15.40 – 16.00 and so on.

How can I put a comma after the last field? (–> 12.00 – 13.00 / 15.40 – 16.00, or even 12.00 – 13.00,)
(I guess I’ve to count the number of rows and when reaching the last one, put the comma …)

Thanks

Method 1

You’re generating whitespace because of the blank line between the echo $end block and the endwnile, and because you’re switching in and out of PHP which means everything between the ?> and <?php – i.e. all of the whitespace – will get echoed out. (HTML then merges the blank lines and spaces into a single space for display.)

You can just do this a single PHP block to save switching in and out of PHP, which will prevent any extra whitespace getting echoed:

<?php
if (have_rows('ore')) {
    while(have_rows('ore')) {
        the_row();

        $start = get_sub_field('start');
        $end = get_sub_field('end');

        if( get_row_index() != 1 ) {
            echo '/';
        }
        echo esc_html($start).' - '.esc_html($end);
    }
    echo ',';
}
?>

Note that I’ve also added esc_html() around the $start and $end values as you echo them. I might also check if these were present or not too before using them, unless you’re positive they’ll always have values.
