表单处理

1、checkbox， 复选框

注意全选的JS：

echo ""

每个checkbox：
\n";

echo "
	$owner	$ip	$vlan	$reason	$expire_time

获取传入的value=$id, 并以逗号进行分割：

$each = implode(",", $_POST["each"]);

2、textarea

<form name="add" action="submit_add.php" method="post">
<textarea name="iplist" rows="20" cols="80"></textarea><br />


分割

$iplist = str_replace("\r\n", ",", $_POST["iplist"]);
$ip = explode(",", $iplist);

针对每行做处理，写数据库，这里只处理了第一列ip。

for ($i = 0; $i <count($ip); $i++)
{
    $b_ip = explode(" ", $ip[$i]);
    $sql_select = "insert into filter (owner, ip, reason) values('$owner', '$b_ip[0]', '$reason');";
    mysql_query($sql_select) or die("Invalid query: " . mysql_error());
    $sql_select = "update filter set expire_real_time=(select date_add(curdate(), interval 60 day)) where ip='$b_ip[0]';";
    mysql_query($sql_select) or die("Invalid query: " . mysql_error());
    echo "

$b_ip[0] add success

";
}
