留言板可以说是所有php入门者都会练习的一个小不上的WEB应用程序了,下面我把我写的一个php留言板实例分享给各位同学,有需要了解的同学可进入参考参考.
1.在你的PHP的根目录下创建一个名为"msgboard"的文件夹.在"msgboard"下创建一个"msglist.php"文件，数据表结构大家可直接导入。
实例代码如下:
CREATE TABLE `msgboard` ( `id` int(10) NOT NULL AUTO_INCREMENT, `username` varchar(50) CHARACTER SET latin1 NOT NULL, `sex` tinyint(1) NOT NULL DEFAULT '1', `msg` text CHARACTER SET latin1 NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
msglist.php 文件,包括了留言增加,删除,修改
实例代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<title>我的留言板</title>
</head>
<body>
<?php
$username = isset($_REQUEST['username']) ? $_REQUEST['username'] : ''; //姓名
$sex = isset($_REQUEST['sex']) ? intval($_REQUEST['sex']) : 1; //性别
$msg = isset($_REQUEST['msg']) ? $_REQUEST['msg'] : ''; //留言
mysql_connect("127.0.0.1", "root", "lzy"); //链接
mysql_select_db("test"); //选择数据库
if (!emptyempty($username) && !emptyempty($msg)) {
mysql_query("INSERT INTO msgboard(username,sex,msg) VALUES('$username','$sex','$msg')");
} else {
echo "输入不正确<br/>";
}
$source = mysql_query("SELECT * FROM msgboard ORDER BY id DESC");
$result = array();
?>
<table border="1" width="1000">
<tr align="center">
<td width="10%">姓名</td>
<td width="10%">性别</td>
<td width="80%">留言内容</td>
</tr>
<tr>
<?php
while ($row = mysql_fetch_array($source)) {
echo '<td>' . $row['username'] . '</td>';
echo '<td>' . ($row['sex'] == 1 ? '男' : '女') . '</td>';
echo '<td>' . $row['msg'] . '</td>';
}
?>
</tr>
</table><p/>
<form action="msglist.php" method="POST">
<table width="1000" align="left">
<tr>
<td width="100%">
姓名:<input type="text" name="username" value=""/>
</td>
</tr>
<tr>
<td width="100%">
性别:男<input type="radio" name="sex" value="1" checked="checked" />
女<input type="radio" name="sex" value="0" />
</td>
</tr>
<tr>
<td width="100%">

</td>
</tr>
