第三步就是php代码处理留言的信息合法性了,
require_once("inc/connect.php");
$myname =get_value("myname",post);
$mymail =get_value("mymail",post);
$mytel =get_value("mytel",post);
$mybook =get_value("mycontent",post);
//exit($mymail);
if(strlen($myname)>100 || strlen($myname)<1){alert("用户长度1-100","");}
if(!@preg_match("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/",$mymail) || strlen($mymail)<6 ){alert("请输入正确的邮箱地址以便我们与你联系!","");}
if(!@preg_match("/\d{3}-\d{8}|\d{4}-\d{7}/",$mytel)){alert("请输入合法的电话如:0731-******","");}
$sql ="select * from tbn where gx_object="$myname" and gx_mail="$mymail"";
$result =mysql_query($sql);
if(mysql_num_rows($result)){
mysql_free_result($result);
alert("提示,你己提交留言,请不要重复提交!","");
}
$sql ="Insert into tbn(gx_content,gx_time,gx_tel,gx_mail,gx_object) value("$mybook","".date("y-m-d")."","$mytel","$mymail","$myname")";
mysql_query($sql) or die(alert("你的留言中有非法数据!",""));
alert("提示:留言成功",$_SERVER["HTTP_REFERER"]);
?>
最四步就是显示留言了.
include("../inc/connect.php");
?>
