Custom User Fields in WordPress

What Are Custom User Fields?

By default, WordPress provides standard user fields like Username, Email, Display Name, Avatar, and Description. However, you can also add custom user fields to tailor user profiles to specific needs.

Creating a Custom User Field

To create a custom user field, let’s consider an example of adding an additional field to store a user’s address. This involves adding code to the functions.php file of the active theme.

• Adding Address Entry Field for Users:

  function my_show_extra_profile_fields() {
  // Display additional profile fields here
  }
  add_action('show_user_profile', 'my_show_extra_profile_fields');
  add_action('edit_user_profile', 'my_show_extra_profile_fields');

• Saving Address Information into Database:

  function my_save_extra_profile_fields() {
  // Save the address information to the database
  }
  add_action('personal_options_update', 'my_save_extra_profile_fields');
  add_action('edit_user_profile_update', 'my_save_extra_profile_fields');

Creating Custom User Fields Using Plugins

WordPress offers numerous plugins to simplify the process of creating custom user fields. One such plugin is Advanced Custom Fields Pro which provides extensive customization options.
