我的关系循环有什么问题？

Question

I'm having a problem with a relationship loop with Advanced Custom Fields in Wordpress.

The first post is shown perfect, but it should execute one more post, but it doesn't.

Can anyone see what's wrong with my code?

<?php $posts = get_field('produkter'); if( $posts ): ?>
<?php foreach( $posts as $post): ?>
<?php setup_postdata($post); ?>

<div class="produkt">
<?php the_title(); ?>
<?php the_content(); ?>

<?php $posts = get_field('fil'); if( $posts ): ?>

<div id="filer">
<div id="topsection" class="laddahem"><div class="topborder"></div>
<h2>Ladda hem</h2>
</div><!-- #top -->

<div class="filhuvud">
    <div class="filtyp">Filtyp</div>
    <div class="fildatum">Datum</div>
    <div class="filstorlek">Filstorlek</div>
</div><!-- .filhuvud -->

<div class="filholder">

<?php foreach( $posts as $post): ?>
<?php setup_postdata($post); ?>

<?php $attachment_id = get_field('filen');
$url = wp_get_attachment_url( $attachment_id );
$title = get_the_title( $attachment_id );

// hämta filstorleken
$filesize = filesize( get_attached_file( $attachment_id ) );
$filesize = size_format($filesize, 1);

$filetype = strtolower(pathinfo($url, PATHINFO_EXTENSION)); ?>

<div class="fil <?php echo $filetype; ?>">
    <div class="filtyp"><a target="_blank" href="<?php echo $url; ?>" ><?php the_title(); ?></a></div>
    <div class="fildatum"><?php the_time('Y-m-d'); ?></div>
    <div class="filstorlek"><?php echo $filesize; ?></div>
</div><!-- .fil -->

<?php endforeach; ?>
<?php wp_reset_postdata(); ?>

</div><!-- .filholder -->

</div><!-- #filer --> 

<?php endif; ?>

</div><!-- .produkt -->

<?php endforeach; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>

The solution was to change the other foreach loop to this:

<?php $files = get_field('fil'); if( $files ): ?>
<?php foreach( $files as $post): ?>
<?php setup_postdata($post); ?>

That made it work exactly how I wanted it.
