User Name Field – Display Name Only

I’m using ACF to create a ‘Project’ post type, we want to have a list of team members, which are selected from the WordPress Users. I’m having an issue with the ‘User’ field, I’ve tried using the ‘User’ field as normal with the Multi-Select option and the following code:

<?php
 
$values = get_field('teammembers');
if($values)
{
	echo '<ul>';
 
	foreach($values as $value)
	{
		echo '<li>' . $value . '</li>';
	}
 
	echo '</ul>';
}
 
// always good to see exactly what you are working with
var_dump($values);
 
?>

But this displays all info about the user along with the profile image:

Array

array(1) { [0]=> array(1) { [“team_member_name”]=> array(11) { [“ID”]=> string(1) “1” [“user_firstname”]=> string(0) “” [“user_lastname”]=> string(0) “” [“nickname”]=> string(15) “NICKNAME” [“user_nicename”]=> string(5) “admin” [“display_name”]=> string(15) “DISPLAYNAME” [“user_email”]=> string(24) “EMAIL ADDRESS” [“user_url”]=> string(0) “” [“user_registered”]=> string(19) “2013-08-19 08:20:47” [“user_description”]=> string(0) “” [“user_avatar”]=> string(236) “” } } }

I’ve also tried using the ‘User’ field in Select mode using the repeater plugin, using the following to display it:

<?php if(get_field('teammembers')): ?>
 
	<ul>
 
	<?php while(has_sub_field('teammembers')): ?>
 
		<li><?php the_sub_field('team_member_name'); ?></li>
 
	<?php endwhile; ?>
 
	</ul>
 
<?php endif; ?>

This again displays more information than I need, along with the profile image:

1, , , NICK NAME, admin, DISPLAY NAME, EMAIL ADDRESS, , 2013-08-19 08:20:47, , PROFILE IMAGE

How can I simply get it to show only the display name?

Any help would be greatly appreciated.

Hi @ashley

You can use an array like so:

$values = get_field('teammembers');
if($values)
{
	echo '<ul>';
 
	foreach($values as $value)
	{
		echo '<li>' . $value['display_name'] . '</li>';
	}
 
	echo '</ul>';
}

Hi elliot, I am attempting to do the same thing, but the username field is part of a Repeater. So it is an array within an array!

Very new to WordPress (though have been kicking goals the last few days!) – can you give me a possible example I can work from?

Obviously the code below is dodge, but show you what i am trying to do. My repeater is ‘notes_added’, it contains a sub-field ‘user_meta’ which currently spits out an array of all user meta information, like ashley described. It also has a sub-field ‘note_text’ – not an array and requires no filtering. I only want to display the NICKNAME of the user on the page, in a table cell.

<?php

if(get_field('notes_added')): ?>
 
 <h1>Notes</h1>
  <table>
 
  <?php while(has_sub_field('notes_added')): ?>
 
    <tr><td><?php the_sub_field('user_meta', 'nickname'); ?></td> <td><?php the_sub_field('note_text'); ?></td></tr>
 
  <?php endwhile; ?>
 
  </table>
 
<?php endif; ?>

Hope you can help, thanks.

Another brave yet misguided attempt – tried to get closer to your example above – am I getting close?

<?php

if( get_field('notes_added') )
{
  while( has_sub_field('user_meta') )
  { 
    $values = get_sub_field('user_meta');
    $content = get_sub_field('note_text');
 
  echo '<h1>Notes</h1><table>';
 
  foreach($values as $value)
  {
    echo '<tr><td>' . $value['nickname'] . '</td> <td>'.$content. '</td></tr>';
  }
 
  echo '</table>';
  }
}

?>

Hi @spacewindow

Please do not ‘blindly code’. Use a debugging function to print out the variable content. You will have your issue fixed in 5 seconds.

Thanks

Point taken. I will go and Google how to do some proper debugging. Currently learning WordPress by myself, with very little guidance – and I am not experienced with PHP at all – any chance you can give me a pointer where I’m going wrong in the meantime?

Sorry, I don’t mean to waste other people’s time through laziness, I assure you this is not the case. I’ve spent several hours trying to figure this out already.

Well it took me a day of searching, but I hit upon the solution. Hope this helps someone to avoid the same trouble.

<?php

$values = get_field('notes_added');

if($values)

  echo'<h1>Notes</h1>';

{
foreach ($values as $value){

  echo '<table><tr><td>'.$value['user_meta']['nickname'].'</td><td>'.$value['note_text'].'</td></tr></table>';
}

}

I have a similar problem. How to display nicknames of users using repeater field and user field. User field works fine when i use it without repeater. When use repeater field and try to display nicknames i see: “1aaaf2<3GMGgGm2<5PppPp2” not nicknames (admin user2 john).

Here is my code:

`<?php while( has_sub_field(‘secret_content_new’) ): ?>

<?php $premium_user = get_sub_field(‘premium_user_list’);?>
<?php if ( $premium_user ) : ?>
<?php foreach($premium_user as $value) {
echo $value[‘nickname’] ;
};?>

<?php endif;?>

<?php endwhile; ?>`

Hi @pawelpoz

Please see the above response from @spacewindow. His code shows the correct syntax for nickname

Thanks

Perhaps this is a difference with newer versions of PHP – but the syntax that @spacewindow provides no longer works – it throws a somewhat vague PHP error of “Warning: Illegal string offset”.

After a lot of digging, I realized that the User field doesn’t apparently return an actual array, but instead returns an array in a string, thus triggering the warning.

Therefore, the following works for retrieving the associative array element by position for nickname.

<?php
$values = get_field('user_field_name');
if($values)
$array = array_values($values);
echo $array[3];
}
?>

For reference on the keys depending on the User info you’re wanting to retrieve, using print_r(array_keys($values)); reveals the following:

Array ( [0] => ID [1] => user_firstname [2] => user_lastname [3] => nickname [4] => user_nicename [5] => display_name [6] => user_email [7] => user_url [8] => user_registered [9] => user_description [10] => user_avatar )

Just swap the number for the element you’re wanting.

In case this helps anyone else save hours of digging.

I have a similar problem like ashley.
For my events (events manager) speakers will be selected from the user database (ACF select user). I only need the person’s name.

I am a PHP beginner and ask for help.
I think I need to store the value from the array in a variable

$ values ​​= Get_Field ('speakers');
$ values ​​= $ value ['display_name'];

is that correct?

The result I want to save as a custom field. This I can enter as Atribut in the format of events manager

Now my beginner questions:
What is the function? Where it stands (funktions.php?)? How can I access it?
For a few tips I would be very grateful !!
many greetings
Ingo

@elliot and if the field to pull the user is a sub field? How would this array? I tried several times, but it returns only the first letter of the field $values = get_sub_field('relationship_user');

This:

$values = get_field('user');		
if($values)
{
echo '<ul>';
foreach($values as $value)
{
echo '<li>' . $value['display_name'] . '</li>';
}
echo '</ul>';
}

dont work, return first letter of the field
This code by @demo38 work:

$values = get_field('user');
	if($values){
	$array = array_values($values);
	echo $array[5];

Why?

@websul – if you’re loading a User Name Field inside of a Relationship Field, then you might want something like:

<?php 
$posts = get_field('relationship_field_name');
if( $posts ): ?>
    <ul>
    <?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) ?>
        <?php setup_postdata($post); ?>
          <li>
            <?php
            $values = get_field('user_field_name');
            if($values)
            $array = array_values($values);
            echo $array[5];
            }
            ?>
          </li>
    <?php endforeach; ?>
    </ul>
    <?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>

You wouldn’t need the sub_field in this case: http://www.advancedcustomfields.com/resources/relationship/

@demo38 Thanks for reply.

Probably for my bad english you don’t understand

I have a repeater field with name “agenda”, in it, i have a sub field “user”, in which case it is a relationship user

Look: https://uploaddeimagens.com.br/imagens/repeater-jpg

• demo38

@websul If your Repeater Field name is Agenda, you might be able to use something like this:

<?php
// check if the repeater field has rows of data
if( have_rows('agenda') ):

echo '<ul>';

    // loop through the rows of data
    while ( have_rows('agenda') ) : the_row();

       echo '<li>';

        // display a sub field value
          $values = get_sub_field('user_field_name');
            if($values)
            $array = array_values($values);
            echo $array[5];
            }

       echo '</li>';

    endwhile;

echo '</ul>';

else :
    // no rows found
endif;
?>

@demo38 Man, u save me. Thank you very much! Worked perfectly for me, just not understand why Elliot codes do not work. Ex: $value['display_name']

• demo38

• August 12, 2015 at 12:31 am

@websul Glad it helped – I’m not sure about the other syntax, I did a lot of troubleshooting a while ago trying to figure things out for the User Field and that’s just what I had pieced together.
