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

这是我的代码。顺便说一句，我正在制作一个登录页面，其中包含功能配置（用于数据库连接）、页眉和页脚页面，并且我使用 WampServer 和 Dreamweaver。

if($_POST['submit']) 
{
    $sql = "SELECT * FROM users WHERE username = '"
    . $_POST['username'] . "' AND password = '"
    . $_POST['password'] . "';";
    $result = mysql_query($sql);

这是你的问题：

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

你有两个连续else的。你应该修改你的代码。

前行没有匹配else。也就是说，打开和关闭大括号不匹配。 保持代码缩进有助于避免此类错误。require("header.php");if

在第 67 行使用 else if($somecondition) 代替，因为在 if-elseif-else 中只能有一个 else 块。您的逻辑也存在错误，我正在输入可能对您有所帮助的新代码。
