使用操作挂钩检查用户是否填写了其他信息。我建议为以下内容使用childtheme或制作自己的插件：

//\'template_redirect\' hook works well for what we need to do. 
add_action( \'template_redirect\', \'vlad_additional_info_check\' );

/**
 * Check if a user has filled out additional required information to complete registration, if not redirect them to page to complete registration.
 */
function vlad_additional_info_check() {
    //If the user is not logged in, or an administrator, we can just return out of the  function and do nothing further.
    if ( ! is_user_logged_in() || current_user_can( \'administrator\' ) ) {
        return;
    }

    //Check if user has filled out their additional information or not. I am using vlad_additional_info as the meta key, you can use anything.
    if ( ! get_user_meta( get_current_user_id(), \'vlad_additional_info\', true ) === "" ) {
        //Here the user has not filled out the fields
        global $post;
        $page_slug = $post->post_name;
        //You want to redirect the user to a page, for example \'complete-registration\', with the for to capture the additional data. First check that they are not already on the page.
        if ( $page_slug !== \'complete-registration\' ) {
            wp_redirect( network_site_url( \'/complete-registration/\' ) );
            exit();
        }
    }
}

//complete-registration.php
//Check if the form data has been submitted
if ( !isset( $_POST[\'submit_complete_registration\'] ) ) {
    //Here is where the form goes
    ?>
    <form action="?" method="post">
        <label>Phone Number *
            <input type="text" value="" name="vlad_phone_number">
        </label>
    </form>
    <?php
} else {
    //Form data has been submitted
    //Here you can validate the forms posted fields. Make sure you collectively validate that all fields are valid, before updating any user meta.
    if ( isset( $_POST[\'vlad_phone_number\'] ) ) {
        //Do validations...
        $valid_number = $_POST[\'vlad_phone_number\'];
    }

    if ( $everything_is_valid ) {
        $user_id = get_current_user_id();
        update_user_meta( $user_id, \'vlad_phone_number\', $valid_number ); //can use any name for your meta
        //...
        //...
        //Now finally update the user meta that we use to check if a user has submitted this info:
        update_user_meta( $user_id, \'vlad_additional_info\', true ); //can use any name for your meta

    } else {
        ?><h2>Please enter a valid...</h2><?php
    }
}

add_shortcode( \'vlad-additional-form\',\'vlad_additional_info_form_render\' );

function vlad_additional_info_form_render() {
    ob_start();
    require \'PLUGIN_OR_CHILDTHEME_DIRECTORY/complete-registration.php\'; //Replace with your own file directory
    return ob_get_clean();
}
