Wordpress ACF Repeater Field - Only pull in first 2 fields

Question

Topic kinda says it all. I need to only pull in the first two fields of an ACF repeater field.

Here is what I am trying to use but it is obviously not right:

<?php $args = [ 'posts_per_page' => 2, 'order' => 'desc']; ?>
<?php $ar = new WP_Query( $args ); ?>

<?php if( $ar->have_rows('prodImgs') ): while ( $ar->have_rows('prodImgs') ) : $ar->the_row(); ?>

    <img src="<?php the_sub_field('prodImg'); ?>" alt="">

<?php endwhile; ?>
<?php endif; ?>

How am I supposed to do this?

Answer 1

<?php
// check if the repeater has data
if( have_rows('prodImgs') ) {
  //counter
  $i=0;
  //loop through the rows
  while( have_rows('prodImgs') ) {
  the_row();
  //check if 2 subfields have been shown
  if ( $i > 1 ) { break; }
  echo "<img src='" . get_sub_field('prodImg_sub') . "' alt='Lorem ipsum'>";
  $i++;
  }
}
?>

You are mixing apples and pears, WP_Query and ACF Repeater field. WP_Query returns the post data, whilst the ACF function have_rows( $repeater_field_name, $post_id ); checks whether there are any data in the custom field repeater that is on your page/post (or if you specify $post_id on the relevant post/page).
