Get All User Meta Information Including Custom Meta User Data

Recently I needed to find a user on my WordPress site with a specific member number that had been assigned at registration. This member number was a custom user meta field that I had created. I wanted to find all the user’s information based on that member number.

I tried using the WordPress ‘get_users’ function but that only returns the WordPress meta and not the custom meta. I ended up using the ‘get_users’ function to find the user ID and then using the ‘get_user_meta’ function to get the rest of the information.

Since the ‘get_user_meta’ function returns arrays, I used the php array_map function to retrieve the values.

$member_id = '1234567889999';
if ($member_arr = get_users(array('meta_key' => 'member_id', 'meta_value' => $member_id, 'fields' => 'ID'))) {
    $user_id = $member_arr[0];
    if ($userdata = get_user_meta($user_id)) {
      $userdata = array_map( function( $a ){ return $a[0]; }, get_user_meta( $user_id ) );
      print_r($userdata);
    }
} else {
  echo 'Member not found';
}

This code will return all information from the user’s profile including any custom meta fields:

Array
(
  [first_name] => test
  [last_name] => user
  [nickname] => testuser
  [description] =>
  [rich_editing] => true
  [comment_shortcuts] => false
  [admin_color] => fresh
  [use_ssl] => 0
  [show_admin_bar_front] => true
  [wp_capabilities] => a:1:{s:10:”subscriber”;b:1;}
  [wp_user_level] => 0
  [entry_id] => 1
  [photo] => https://example.com/wp-content/uploads/gravity_forms/1-4ed7200bd442a04566979b2fc2751c06/2013/06/cindy.jpg
  [travel_log] => Florida 9/2/2013
Maine 1/2/2014
  [member_id] => 1234567889999
)
