Hello,

I’m trying to make a conditional to show a message if the field ‘downloads’ is empty. ‘downloads’ is a repeater field.

The following code doesn’t show any message
`<?php if( have_rows(‘downloads’) ): ?>
<?php while( have_rows(‘downloads’) ): the_row();
// vars
$link = get_sub_field(‘file’);
$name = get_sub_field(‘file_name’);
?>
<?php if( $link ): ?>
<a href=”<?php echo $link; ?>” target=”_blank”> <?php echo $name; ?>
<?php endif; ?>
</a>
<?php endwhile; ?>
<?php endif; ?>`

and the following code should show a message if the field ‘downloads’ is empty but doesn’t work:

`<?php if( have_rows(‘downloads’) ): ?>
<?php while( have_rows(‘downloads’) ): the_row();
// vars
$link = get_sub_field(‘file’);
$name = get_sub_field(‘file_name’);
?>
<?php if( $link ): ?>
<a href=”<?php echo $link; ?>” target=”_blank”> <?php echo $name; ?>
<?php endif; ?>
</a>

<?php endwhile; else : ?>
<p><?php _e( ‘Sorry, no files attached.’ ); ?></p>?>
<?php endif; ?>`

Can someone tell me what I’m doing wrong, please? Probably the problem is my basic knowledge in PHP… ?

Thank you!

EDIT — Nevermind! Seems that the editor of this website replaces quotes.

It looks like you’re using sloped quotes ‘’, and you should use regular quotationmarks like ” or “”. This type of thing occurs sometimes when you copy code from a website. Could very well be the problem!

The loop you’re using should work. Tested a simplified version of your code. Are you sure there are no downloads present?

<?php if( have_rows('downloads') ): ?>
	<?php while( have_rows('downloads') ): the_row();
	echo 'Whoohoo! A download!';
	?>
	<?php endwhile; ?>
<?php else:
echo 'No downloads found';
endif; ?>

Hello zwaarcontrast,

Than you for your reply.

I tried similar code and worked.

I think the problem is when I check if the field ‘‘file’ is not empty to not show it in this case.

  
  $link = get_sub_field(‘file’);
  $name = get_sub_field(‘file_name’);
  ?>
  <?php if( $link ): ?>
  <a href=”<?php echo $link; ?>” target=”_blank”> <?php echo $name; ?>
  <?php endif; ?>
  </a>

Are you sure there are no downloads present?

Yes, I am.

When There is a attached file look like this:

and when there is not files look like this:

It’s strange because I don’t have any error in my error log also the debug of WP and my server is ON so.. I don’t know exactly what is the problem.

Thank you!
