php - フォームの登録 + クエリの挿入が機能しない 修正方法

Question

ユーザーからの入力が必要な登録フォームがあります。フォームは正常に機能していましたが、データベースに値を挿入しません。誰でも私を助けることができますか？

すべてのコードを表示しますが、必要なのは挿入クエリに関するヘルプです。

register.php

<?php require_once('for members/scripts/connect.php'); ?>

<?php
function specializationQuery(){

$specData = mysql_query("SELECT * FROM specialization");

  while($recordJob = mysql_fetch_array($specData)){

     echo'<option value="' . $recordJob['specialization_id'] .  '">' . $recordJob['specialization_name'] . '</option>';

  }
