Radiok,
I figured it out. Fairly easy actually.
I took the field name created in the custom area (mine was ‘rpr_clinic_name’), and just pushed it into a new table section of the admin page(rpr-admin-menu.php) using the class from email:
<table class="widefat fixed" cellspacing="0">
<thead>
<tr class="thead">
<th scope="col" id="cb" class="manage-column column-cb check-column" style=""><input type="checkbox" /></th>
<th scope="col" id="clinic" class="manage-column column-email" style=""><?php _e( 'Clinic', 'register-plus-redux' ); ?></th>
then
<tbody id="users" class="list:user user-list">
<?php
/*.object.*/ $user_query = new WP_User_Query( array( 'role' => 'rpr_unverified' ) );
if ( !empty( $user_query->results ) ) {
$style = '';
foreach ( $user_query->results as $user ) {
$style = ( $style == ' class="alternate"' ) ? '' : ' class="alternate"';
?>
<tr id="user-<?php echo $user->ID; ?>"<?php echo $style; ?>>
<th scope="row" class="check-column"><input type="checkbox" name="users[]" id="user_<?php echo $user->ID; ?>" name="user_<?php echo $user->ID; ?>" value="<?php echo $user->ID; ?>"></th>
<td class="username column-username">
<strong><?php if ( current_user_can( 'edit_users' ) ) echo '<a href="', esc_url( add_query_arg( array( 'user_id' => $user->ID, 'wp_http_referer' => urlencode( stripslashes( $_SERVER['REQUEST_URI'] ) ) ), 'user-edit.php') ), '" >', $user->user_login, '</a>'; else echo $user->user_login; ?></strong><br />
<div class="row-actions">
<?php if ( current_user_can( 'promote_users' ) ) echo '<span class="edit"> <a href="', wp_nonce_url( add_query_arg( array( 'page' => 'unverified-users', 'action' => 'approve_user', 'user_id' => $user->ID, 'wp_http_referer' => urlencode( stripslashes( $_SERVER['REQUEST_URI'] ) ) ), 'users.php'), 'register-plus-redux-unverified-users' ), '" >', __( 'Approve', 'register-plus-redux' ), '</a></span> | ', "\n"; ?>
<?php echo '<span class="edit"> <a href="', wp_nonce_url( add_query_arg( array( 'page' => 'unverified-users', 'action' => 'send_verification_email', 'user_id' => $user->ID, 'wp_http_referer' => urlencode( stripslashes( $_SERVER['REQUEST_URI'] ) ) ), 'users.php'), 'register-plus-redux-unverified-users' ), '" >', __( 'Send Verification', 'register-plus-redux' ), '</a></span> ', "\n"; ?>
<?php if ( current_user_can( 'delete_users' ) ) echo '<span class="delete"> | <a href="', wp_nonce_url( add_query_arg( array( 'page' => 'unverified-users', 'action' => 'delete_user', 'user_id' => $user->ID, 'wp_http_referer' => urlencode( stripslashes( $_SERVER['REQUEST_URI'] ) ) ), 'users.php'), 'register-plus-redux-unverified-users' ), '" class="submitdelete">', __( 'Delete', 'register-plus-redux' ), '</a></span> ', "\n"; ?>
</div>
</td>
<td class="email column-email"><?php echo $user->rpr_clinic_name; ?></td>
And viola! it shows the custom field. I would probably take out one of the other table columns as it does start to get full fast if exact spacing isn’t set up.
