    Hi!

    I’ve inserted this code in archive.php:

    <?php
  $mykey_values = get_post_custom_values('distance');
  foreach ( $mykey_values as $key => $value ) {
    echo "($value km)";
  }
?>

    but I get this warning:
    “PHP Warning: Invalid argument supplied for foreach() in D:\Sites\Bedui\www\wordpress\wp-content\themes\retromania\archive.php on line 44 PHP Warning: Invalid argument supplied for foreach() in D:\Sites\Bedui\www\wordpress\wp-content\themes\retromania\archive.php on line 44 “

    Can anyone see what I’ve done wrong?

    The custom value is a certain number of kilometers that I’ve cycled on that day. ??

    Thank you!

    Thanks! It works for the single.php, but for the index.php I get this error:

    PHP Warning: Invalid argument supplied for foreach() in wordpress\wp-content\themes\retromania\index.php on line 18 PHP Warning: Invalid argument supplied for foreach() in wordpress\wp-content\themes\retromania\index.php on line 18 PHP Warning: Invalid argument supplied for foreach() in wordpress\wp-content\themes\retromania\index.php on line 18

    And for the archive.php I get this error:
    PHP Warning: Invalid argument supplied for foreach() in wordpress\wp-content\themes\retromania\archive.php on line 44

    Line 18 and Line 44 is this line in both those pages:
    foreach ( $mykey_values as $key => $value ) {

    Do you know why I get error like that?

    (I use this line right after the title of a post in both the single.php, archive.php and index.php – your code works fine for the single.php, but not for the archive.php and the index.php.

    Thanks a bunch if you can help me!

    <?php
  $mykey_values = get_post_custom_values('distance', $post->ID);
  if(is_array($mykey_values)):
     foreach ( $mykey_values as $key => $value ) {
       echo "($value km)";
     }
  endif;
?>
