Question

嗨，我在检查此代码时遇到了一些麻烦。它似乎在我的本地wamp服务器上工作得非常好但是当我在godaddy托管服务器上运行时，它不起作用。我尝试使用来自不同托管公司的另一台服务器，它登录了我。我不知道如何/在哪里检查错误。

我也尝试在托管配置上更改php版本，看看它是否真的有效，但事实并非如此。

有人可以提供建议吗

以下是我的登录页面的完整代码。

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

  $LoginRS__query=sprintf("SELECT username, password FROM lib WHERE username=%s AND password=%s",

您确定服务器上有Connections/dbconnect.php吗？看起来你没有得到数据库连接。

登录功能无法在PHP中运行
