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

Question

I have created a special form within my site that allows my users to enter a key. I am using add_user_meta() to add the meta data into the database. I want to be able to see this key when I click on users in the admin center.
How would I go about adding to this column?
Below is the meta data info im using
add_user_meta($userId,'code','12345');
We just want to be able to add it to the view on users.php in the table displaying username email and role.
I have used code like this to display the user id but I can not figure out how to display their meta.
add_filter('manage_users_columns', 'pippin_add_user_id_column');
function pippin_add_user_id_column($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;
}

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'] );
}
?>

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 );

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 );

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;
}
?>

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;
}
