当我进入下一页（从index.php到index.php？page = 2）时，脚本忘记搜索关键字“for example country=US”，并在下一页显示默认选项(country=)。然后我也尝试添加（WHERE country =），但这种方式我觉得这行不行“‘.mysql_real_escape_string($_GET['country']）。’”：脚本忘记搜索关键字
foreach($_POST as $key => $value)
{
$clean[$key] = mysql_real_escape_string(trim($value));
}
$name=$clean['name'];
$country=$clean['country'];
$ip=$clean['ip'];
$map=$clean['map'];
$o="AND";
对不起，在脚本中的混乱，因为我有从我在网上找到的部分收集它等等，所以我仍然没有足够的技能来找出什么是错的。感谢您的任何建议。
