Adjusted some of your code. This should work:
[php]<?php
/**
* Block Name: Testimonials
*
* This is the template that displays the testimonials loop block.
*/
$argType = get_field(‘loop_argument_type’);
if ($argType == "count") :
$args = array(
‘orderby’ => ‘title’,
‘post_type’ => ‘testimonials’,
‘posts_per_page’ => get_field(‘testimonial_count’)
);
else :
$testimonials = get_field(‘select_testimonials’);
$args = array(
‘orderby’ => ‘title’,
‘post_type’ => ‘testimonials’,
‘post__in’ => $testimonials
);
endif;
$the_query = new WP_Query($args);
?>
<section class="testimonials">
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="testimonialHolder">
<?php
if ($the_query->have_posts()) {
while ($the_query->have_posts()) {
$the_query->the_post(); ?>
<div class="item">
<div class="testimonial">
<?php $image = get_field(‘foto’, get_the_ID()); ?>
<img src="<?php echo $image[‘url’]; ?>" class="img-circle" alt="<?php echo $image[‘alt’]; ?>" />
<h4><?php the_field(‘naam’, get_the_ID()); ?></h4>
<p><?php the_field(‘samenvatting’, get_the_ID()); ?></p>
</div>
</div>
<?php }
} else { ?>
<div class="item">
<div class="testimonial">
<h3>No Testimonials Found</h3>
</div>
</div>
<?php }
wp_reset_postdata();
?>
</div>
</div>
</div>
</div>[/php]
