Hello

ACF is great plugin for WP. I have a small question regarding the ACF Repeater.
I am using a CPT, from ACF custom fields, I have created taxonomy and a text field. Please check the screenshot:

<?php $args = array( 'post_type' => 'fares', 'posts_per_page' => 8 );
			$the_query = new WP_Query( $args );
			if ( $the_query->have_posts() ) { while ( $the_query->have_posts() ) {
      $the_query->the_post(); ?>

				<div class="test">
					<?php the_title(); ?> <br>
					<?php if( have_rows('fares_from') ): while ( have_rows('fares_from') ) : the_row(); ?>
						<?php $term = get_sub_field('fares_from_taxonomy'); ?>
						<pre> <?php //print_r($term); ?> </pre>
	        <span><?php echo $term->name; ?></span>
	        <span><?php echo get_sub_field('fare_price'); ?></span>
	    		<?php endwhile; endif; ?>
	    		<hr>
				</div>

      <?php } // end while
} // endif
// Reset Post Data
wp_reset_postdata(); ?>

Here is my code, which is pulling the title of the post and all ACF repeater fields, but here I really want only the lowest value field only.
The data I want is:
title of the post, Taxonomy term with the lowest value.

Could you please help?

Thank you

if (have_rows('fares_from')) {
  $term = false;
  $fare_price = false;
  while (have_rows('fares_from')) {
    the_row();
    if ($fare_price === false || get_sub_field('fare_price') < $fare_price) {
      $fare_price = get_sub_field('fare_price');
      $term = get_sub_field('fares_from_taxonomy');
    }
  } // end while have rows
  if ($term)  {
    ?>
      <span><?php echo $term->name; ?></span>
      <span><?php echo $fare_price; ?></span>
    <?php 
  }
} // end if have rows
