Add Custom User-Meta to the Users Admin page in WordPress

5 comments

1. This example was created with the help of these two pages from the WordPress codex.

   https://codex.wordpress.org/Plugin_API/Action_Reference/edit_user_profile
   https://codex.wordpress.org/Plugin_API/Action_Reference/personal_options_update

   It is for displaying and updating the custom user meta data.

   <?php
   
   // Hooks near the bottom of profile page (if current user) 
   add_action('show_user_profile', 'custom_user_profile_fields');
   
   // Hooks near the bottom of the profile page (if not current user) 
   add_action('edit_user_profile', 'custom_user_profile_fields');
   
   // @param WP_User $user
   function custom_user_profile_fields( $user ) {
   ?>
       <table class="form-table">
           <tr>
               <th>
                   <label for="code"><?php _e( 'Custom Meta' ); ?></label>
               </th>
               <td>
                   <input type="text" name="code" id="code" value="<?php echo esc_attr( get_the_author_meta( 'code', $user->ID ) ); ?>" class="regular-text" />
               </td>
           </tr>
       </table>
   <?php
   }
   
   
   // Hook is used to save custom fields that have been added to the WordPress profile page (if current user) 
   add_action( 'personal_options_update', 'update_extra_profile_fields' );
   
   // Hook is used to save custom fields that have been added to the WordPress profile page (if not current user) 
   add_action( 'edit_user_profile_update', 'update_extra_profile_fields' );
   
   function update_extra_profile_fields( $user_id ) {
       if ( current_user_can( 'edit_user', $user_id ) )
           update_user_meta( $user_id, 'code', $_POST['code'] );
   }
   
   ?>
   

2. The answer above from Mordred worked for me after changing the second add_filter to add_action. Here’s the modified code:

   function yoursite_manage_users_columns( $columns ) {
   
       // $columns is a key/value array of column slugs and names
       $columns[ 'custom_field' ] = 'Subscription';
   
       return $columns;
   }
   
   add_filter( 'manage_users_columns', 'yoursite_manage_users_columns', 10, 1 );
   
   function yoursite_manage_users_custom_column( $output, $column_key, $user_id ) {
   
       switch ( $column_key ) {
           case 'custom_field':
               $value = get_user_meta( $user_id, 'custom_field', true );
   
               return $value;
               break;
           default: break;
       }
   
       // if no column slug found, return default output value
       return $output;
   }
   
   add_action( 'manage_users_custom_column', 'yoursite_manage_users_custom_column', 10, 3 );
   

3. To add custom user_meta fields to users.php you need to do the following:

   function yoursite_manage_users_columns( $columns ) {
   
       // $columns is a key/value array of column slugs and names
       $columns[ 'custom_field' ] = 'Subscription';
   
       return $columns;
   }
   
   add_filter( 'manage_users_columns', 'yoursite_manage_users_columns', 10, 1 );
   
   function yoursite_manage_users_custom_column( $output, $column_key, $user_id ) {
   
       switch ( $column_key ) {
           case 'custom_field':
               $value = get_user_meta( $user_id, 'custom_field', true );
   
               return $value;
               break;
           default: break;
       }
   
       // if no column slug found, return default output value
       return $output;
   }
   
   add_filter( 'manage_users_custom_column', 'yoursite_manage_users_custom_column', 10, 3 );
   

4. Realising this is a bit of an old thread, however I was stuck on a very similar problem, and thought I would share what I found which proved to be a very simple solution.

   <?php
   add_filter('manage_users_columns', 'pippin_add_user_id_column');
   function pippin_add_user_id_column($columns) {
       $columns['user_id'] = 'User ID';
       return $columns;
   }    
   
   add_action('manage_users_custom_column',  'pippin_show_user_id_column_content', 10, 3);
   function pippin_show_user_id_column_content($value, $column_name, $user_id) {
       $user = get_userdata( $user_id );
       if ( 'user_id' == $column_name )
           return $user_id;
       return $value;
   }
   ?>

5. To make the additional woocommerce fields editable you can use the following filter (in the example a custom field is added in the billing section).

   add_filter('woocommerce_customer_meta_fields', 'add_woocommerce_customer_meta_fields');
       function add_woocommerce_customer_meta_fields($fields)
       {
         if (isset($fields['billing']['fields'])) {
           $fields['billing']['fields']['your_custom_meta'] = array(
             'label' => __('Friendly name', 'woocommerce'),
             'description' => ''
           );
         }
         return $fields;
       }
