Hi,

I am pulling in some ACF data from a defined page in my template – this works as per code below, what I would like to do is define the number of ‘results’ displayed and pull them in, in a random format – so lets say their are 10 copies of the repeater field ‘testimonialREPEATER’ on page id 1480. Id like the code below to pull all the info it does – BUT to just pull a random 3 of the 10, so that only 3 rather than all 10 are displayed… Is this possible?

<?php

			// check if the repeater field has rows of data
			if( have_rows('testimonialREPEATER', 1480) ):
			
				// loop through the rows of data
				while ( have_rows('testimonialREPEATER', 1480) ) : the_row();
			
			?>
			
                    <!-- v2 -->
					<div class="testimonialItemWrapper">
                    <div class="testieImageFocus<?php the_sub_field('testimonialIMAGEFOCUS'); ?> testimonialItemQUOTEWrapper">
                    <?php the_sub_field('testimonialQUOTE'); ?>
                    <h3><?php the_sub_field('testimonialAUTHOR'); ?><?php if( get_sub_field('testimonialPOSITION') ): ?> - <?php the_sub_field('testimonialPOSITION'); ?><?php endif; ?><?php if( get_sub_field('testimonialCOMPANY') ): ?>, <?php the_sub_field('testimonialCOMPANY'); ?><?php endif; ?>
                    </h3>
                    </div>
                    <div class="testieImageFocus<?php the_sub_field('testimonialIMAGEFOCUS'); ?> testimonialItemIMGWrapper" style="background-image:url('<?php the_sub_field('testimonialIMG'); ?>');">
                    <!--<img src="<?php the_sub_field('testimonialIMG'); ?>" title="<?php the_sub_field('testimonialIMG'); ?>" alt="<?php the_sub_field('testimonialIMG'); ?>"/>-->
                    </div>
                    </div>
                    
			
            <?php
				endwhile;
			
			else :
			
				// no rows found
			
			endif;
			
			?>

I would do it a different way and not use an acf have_rows() loop

$repeater = get_field('testimonialREPEATER', 1480);
$indexes = array_rand($repeater, 3);
foreach ($indexes as $index) {
  var_dump($repeater[$index]);
}

Using the above, instead of using the_sub_field() you would need to access the value in the array, for example testimonialQUOTE would be

echo $repeater[$index]['testimonialQUOTE'];
