php留言本
最近学PHP 参考手册写了这么个留言本.没有什么难点.就是些php操作mysql数据库函数的应用.加个自己的思路
注意编码问题
代码如下:
//提交表单和处理显示的页面

第二个页面:
<?php

$contact = $_POST["contact"];
$message = $_POST["message"];
$link = mysql_connect('localhost','root','#####');
if (!$link) {
die('could not connect :' .mysql_error());
}
mysql_select_db('notebook',$link); //选择数据库
mysql_query("set names utf-8"); //解决中文乱码问题
/*将表单信息插入数据库*/
mysql_query("insert into info (username,contact,dt,message) values ('$username','$contact',now(),'$message')",$link);
header("Location: http://localhost/notebook.php");
?>
$username = $_POST["username"];
$contact = $_POST["contact"];
$message = $_POST["message"];
$link = mysql_connect('localhost','root','#####');
if (!$link) {

}
mysql_select_db('notebook',$link); //选择数据库

mysql_query("insert into info (username,contact,dt,message) values ('$username','$contact',now(),'$message')",$link);
