解析错误：第70行的C：\ wamp \ www \ Discussion Forums \ login.php中的解析错误

这是我的代码。顺便说一下，我正在创建一个具有功能配置（用于数据库连接），页眉和页脚页面的登录页面，我使用WampServer和Dreamweaver。

<?php

$db = mysql_connect($dbhost, $dbuser, $dbpassword);
mysql_select_db($dbdatabase, $db);
if($_POST['submit']) 
{
    $sql = "SELECT * FROM users WHERE username = '"
    . $_POST['username'] . "' AND password = '"
    . $_POST['password'] . "';";
    $result = mysql_query($sql);
    $numrows = mysql_num_rows($result);
    $result = mysql_query($sql);
    $numrows = mysql_num_rows($result);
    if($numrows == 1) 
        {
            $row = mysql_fetch_assoc($result);
            if($row['active'] == 1)

Answer 1

这是你的问题：

else {
header("Location: " . $config_basedir . "/login.php?error=1");
}
else {

你有两个连续的else。你应该修改你的代码。

Answer 2

else行之前的require("header.php");没有匹配的if。也就是说，打开和关闭花括号不匹配保持代码缩进有助于避免此类错误。

Answer 3

在第67行，使用if if（$ somecondition）代替，因为在if-elseif-else中只能有一个else块。你的逻辑中也存在错误我正在使用它可能对你有帮助的新代码。
