看下面的代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>添加信息</title>
<style type="text/css">
.ipt{width:180px;height:30px;border-radius:5px;
outline:none;border:1px solid #eee;box-sizing:border-box;padding-left:15px;}
.txt{width:250px;height:200px;}
.sub{width:50px;height:20px;border:1px solid #eee;background:#eee;color:#ff7575;}
</style>
</head>
<body>
<form method="post" action="addabout.php">
标题：<input type="text" name="title" class="ipt">
</br></br>
内容：<textarea cols="50" rows="5" name="content" class="txt"></textarea></br></br>
<input type="submit" value="添加" class="sub">
</form>
</body>
</html>表单提交到 addabout.php 页面 进行处理
代码如下：
<?php
require_once('conn.php');
//htmlspecialchars() 过滤html
$title = htmlspecialchars($_POST['title']);
$content = htmlspecialchars($_POST['content']);
if(empty($title)){
echo "请输入标题";
}else if(empty($content)){
echo "请输入内容";
}else{
$sql = "insert into `about`(title,content) values('$title','$content')";
$res = mysql_query($sql);
if($res){
echo "<script>alert('添加信息成功');location.href='about.php';</script>";
}else{
echo "<script>alert('添加信息失败');history.go(-1);</script>";
}
}
?>获取表单的信息，然后添加到数据库
