     <form action = "" method = "POST">

主要問題在表中選擇框和文本區在MySQL中值是，它沒有顯示textarea的價值，這是我手動更新選擇框通過PHPmyadmin，但它顯示在文本框中的很好。

更新：字段現在更新成功！即使文本區域和選擇框在表格中更新。但是，該值未顯示在textarea或選擇框中。所以問題仍然存在！

可變的user_data：

$user_data = user_data($session_user_id,'user_id','username','password','first_name','last_name','email','gender','age','location','about_me');
