Answer 1

第二个问题回答，您尚未将变量分配给变量，mysql_affected_rows也是空的。

$gb_query =     "insert into guestbook
        values(0, '$name', '$email', '$comment', '$date')";

$sql = mysql_query($gb_query);
$res = mysql_affected_rows($sql);

Answer 2

听起来这个错误是由阻塞目录的Xampp配置引起的。如果您在开发机器上并且不关心安全性，请在xampp下的apache / conf目录中查找名为httpd.conf的文件。

你会在那里找到类似于

的指令

<Directory />
    Options FollowSymLinks
    AllowOverride none
    Order deny,allow
    Allow from none
    Deny from all
</Directory>

将其替换为

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    Deny from none
</Directory>

这使得根驱动器上的每个文件都可以被Web服务器访问，这在开发机器上是可以的（虽然有些人肯定会争论这一点），但在生产中并不是一个好主意。
