Php Dreamweaver在mySQL上更改数据

我试图使用dreamweaver更新记录创建一个页面，用户可以在其中编辑他们的帐户，但一旦我提交，数据库中的任何内容都不会更新。有什么建议吗？代码如下。请帮帮我

<?php require_once('../../Connections/mySQL.php'); ?>
<?php

session_start();

if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

$editFormAction = $_SERVER['PHP_SELF'];

  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);

哇，这是我见过的最开放的问题。原因有很多，除非你发布一些代码，否则我们无法接近。对不起。。。我开始学习PHP和mySQL。将URL与表单值连接起来，测试页面，查看页面输出。如果只是白色，则利用
exit（）
遍历代码，直到
exit（）
不再触发。
