Question

On a WordPress site I’m developing, I have created a fcustom user meta field (matrix-diagnosis) where people can add additional information.

I’m trying to display a list of all users who have completed this field (and their response), but would like to omit those who have not completed the field.

After a LOT of Googling, the closest I’ve gotten is this bit of code…

<ul class="unstyled">

<?php
  //these are the arguments for the get_users function below
  $args  = array(
     'fields' => 'all_with_meta',
     'meta_query' => array('key' => 'matrix-diagnosis')
  );

  //get_users calls WP_User_Query and returns an array of matching users
  $users = get_users($args);

  //leaving an array of $users sorted by the value of meta 'points'
  foreach ($users as $user) : ?>

     <li>
        <h3><?php the_author_meta( 'first_name', $user->id ); ?> <?php the_author_meta( 'last_name', $user->id ); ?></h3>
        <p><?php the_author_meta( 'matrix-diagnosis', $user->id ); ?></p>
     </li>

<?php endforeach; /* end for each function */ ?>

</ul>

This actually will query the database and display a list of all users and their responses, but if someone has not completed the field, displays just their name. How do I scrub the list of people for whom that field has no value?

I have a hunch the secret lies not in using an array, but in using the $wpdp tag, which I have had no luck with to date.

Thanks in advance!

I think you can change the_author_meta( 'matrix-diagnosis', $user->id ); to $matrix_check = get_the_author_meta( 'matrix-diagnosis', $user->id, true ); and on your foreach statment check if empty like:

foreach ($users as $user) : ?>
<?php $matrix_check = get_the_author_meta( 'matrix-diagnosis', $user->id, true );
if ($matrix_check != "") {?>
     <li>
        <h3><?php the_author_meta( 'first_name', $user->id ); ?> <?php the_author_meta( 'last_name', $user->id ); ?></h3>
        <p><?php the_author_meta( 'matrix-diagnosis', $user->id ); ?></p>
     </li>
