Answer 1

、これらの変数が定義されていない場合は、以下の条件文が警告を発行しないように$new_user = null;と$error = null;を追加します。

function process_carer_registration() { 
    $new_user = null; 
    $error = null; 

Answer 2

あなたは

このラインif ($new_user) : ?>変更if (isset($new_user)) : ?>

と

<?php if ($error) : ?>変化にこのエラーからgetridするisset()機能を使用することができます<?php if (isset($error)) : ?>
