For developers, coding provides greater control over WordPress custom login fields development.

Step 1: Add Custom Fields Using login_form Action Hook

Add the following code to your functions.php file:

    <p>
        <label for="custom_field">Custom Field</label>
        <input type="text" name="custom_field" id="custom_field">

Step 2: Save Custom Fields Data

Modify the authentication process to store the data:

function save_custom_login_field($user_login, $user) {
    if (isset($_POST['custom_field'])) {
        update_user_meta($user->ID, 'custom_field', sanitize_text_field($_POST['custom_field']));
    }
}
add_action('wp_login', 'save_custom_login_field', 10, 2);

Step 3: Validate the Custom Login Field

Ensure the field is not empty before login:

function validate_custom_login_fields($user, $password) {
    if (empty($_POST['custom_field'])) {
        return new WP_Error('empty_field', __('Custom field cannot be empty.', 'textdomain'));
    }
    return $user;
}
add_filter('authenticate', 'validate_custom_login_fields', 30, 2);
