php留言系统(2),php留言系统

1、参照之前的(mvc框架总结)将整体框架定下来之后,那么请求默认参数将变为:

<span>//</span><span>默认请求首页:
    </span><span>//</span><span>P=front
    </span><span>//</span><span>C=fIndex
    </span><span>//</span><span>A=show</span>
Nach dem Login kopieren

1.1 找到控制器fIndexController下的动作:

<span>//</span><span>首页展示动作</span>
        <span>public</span><span> function showAction()
        {
            </span><span>//</span><span>防止恶意调用</span>
            $<span>this</span>-><span>checkAuthority();
            </span><span>//</span><span>不需要具体模型,直接载入模版</span>
            require CUR_VIE_PATH.<span>'</span><span>index.html</span><span>'</span><span>;
        }</span>
Nach dem Login kopieren

2、防止恶意调用这一块放于我们的Controller层面,所有模型几乎都要用到,因此将其放于基础模型,、

<span>/*</span><span>
     * 防止恶意调用方法,适用于全部方法
     </span><span>*/</span>
    <span>protected</span><span> function checkAuthority()
    {
        </span><span>if</span>(!defined(<span>'</span><span>IN_NG</span><span>'</span><span>))
        {
            exit(</span><span>"</span><span>you no authority</span><span>"</span><span>);
        }
    }</span>
Nach dem Login kopieren

随时调用该方法

3、拒绝php低版本,由于总是在运行,所以直接放入初始文件Framework.class.php

4.1将 CSS做成包含文件

每个页面都要导入CSS,着实麻烦,我们定一个文件title.inc.html。

但是每个页面却有一个不相同的CSS,那么可以定义一个常量来证明本页。

define('SCRIPT','index');

<title>Your Title</title>
    <?<span>php
        require </span><span>'</span><span>application/view/front/title.inc.html</span><span>'</span>
    ?>
</head>
Nach dem Login kopieren

php留言系统(2),php留言系统_PHP教程其中title.inc.html代码

<link rel=<span>"</span><span>shortcut icon</span><span>"</span> href=<span>"</span><span>favicon.ico</span><span>"</span> />
<link rel=<span>"</span><span>stylesheet</span><span>"</span> type=<span>"</span><span>text/css</span><span>"</span> href=<span>"</span><span>public/front/css/1/basic.css</span><span>"</span> />
<link rel=<span>"</span><span>stylesheet</span><span>"</span> type=<span>"</span><span>text/css</span><span>"</span> href=<span>"</span><span>public/front/css/1/<?php echo SCRIPT?>.css</span><span>"</span> />
Nach dem Login kopieren

5.2 创建注册页面register.html

<span>参数请求为:
    请求注册页
        P</span>=<span>front
        C</span>=<span>fRegister
        A</span>=show
Nach dem Login kopieren

代码为:

<div id=<span>"</span><span>register</span><span>"</span>>
        <h2>会员注册</h2>
        <form method=<span>"</span><span>post</span><span>"</span> action=<span>"</span><span>post.php</span><span>"</span>>

php留言系统(2),php留言系统_PHP教程5.3点击头像弹出选择头像框:

<img  src=<span alt="php留言系统(2),php留言系统_PHP教程" >"</span><span>public/front/face/m01.gif</span><span>"</span> alt=<span>"</span><span>头像选择</span><span>"</span><span>

Nach dem Login kopieren

php留言系统(2),php留言系统_PHP教程这个页面存放着64 张头像页面,可以通过数组循环的方式罗列出来

<?php <span>foreach</span> (range(<span>1</span>,<span>9</span>) <span>as</span> $number) {?>
<dd><img  src=<span alt="php留言系统(2),php留言系统_PHP教程" >"</span><span>face/m0<?php echo $number?>.gif</span><span>"</span> /></dd>
<?php }?>

6.提交数据
将数据提交到本页,必须做一个名值对,用来判断是否提交了数据。

?action=<span>register
也可以设计一个隐藏字段来做名值对
</span><<span>input
type</span>=<span>"</span><span>hidden</span><span>"</span><span>
name</span>=<span>"</span><span>action</span><span>"</span><span>
value</span>=<span>"</span><span>register</span><span>"</span>
/>

6.1核对验证码
验证码的用途是为了防止恶意注册和一些表单伪造跨站攻击等。
验证码里保存在session 里面,可以判断是否是当前表单提交,而刷新一次后验证码随
即变化,又可以防止多次恶意注册。

<span>if</span> (!($_POST[<span>'</span><span>yzm</span><span>'</span>] == $_SESSION[<span>'</span><span>code</span><span>'</span><span>])) {
_alert_back(</span><span>'</span><span>验证码有误,请重新输入!</span><span>'</span><span>);
}</span>
Nach dem Login kopieren

6.2.接受数据

<span>设计变量,将数据提交出来赋值给变量
$_username
</span>=<span>
$_POST[</span><span>'</span><span>username</span><span>'</span><span>];
也可以通过一个数组来存放提交过来的值
$_clean
</span>=<span>
array();
$_clean[</span><span>'</span><span>username</span><span>'</span><span>]
</span>=<span>
$_POST[</span><span>'</span><span>username</span><span>'</span>]
Nach dem Login kopieren

6.3各种限制与过滤

<span>1.首先,必须去掉两边的空格
$_string </span>= trim($_string);
Nach dem Login kopieren
<span>2.其次长度限制
</span><span>if</span> (mb_strlen($_string,<span>'</span><span>utf-8</span><span>'</span>) < $_min_num || mb_strlen($_string,<span>'</span><span>utf-8</span><span>'</span>) > $_max_num)
Nach dem Login kopieren
<span>3.敏感字符限制
$_char_pattern </span>= <span>'</span><span>/[<>\'\"\ \ ]/</span><span>'</span><span>;
</span><span>if</span> (preg_match($_char_pattern,$_string)) {}
Nach dem Login kopieren
<span>4.敏感用户名限制
$_mg[</span><span>0</span>] = <span>'</span><span>22</span><span>'</span><span>;
$_mg[</span><span>1</span>] = <span>'</span><span>11</span><span>'</span><span>;
$_mg[</span><span>2</span>] = <span>'</span><span>33</span><span>'</span><span>;
</span><span>foreach</span> ($_mg <span>as</span><span> $value) {
$_mg_string .</span>= <span>'</span><span>[</span><span>'</span>.$value.<span>'</span><span>]</span><span>'</span>.<span>'</span><span>\n</span><span>'</span><span>;
}
</span><span>if</span><span> (in_array($_string,$_mg)) {
_alert_back($_mg_string.</span><span>'</span><span>以上敏感用户名不得注册!</span><span>'</span><span>);
}</span>
Nach dem Login kopieren
<span>5.转义输入,有效防止SQL 注入问题
</span><span>//</span><span>mysql_escape_string();
</span><span>//</span><span>addslashes()</span>
<span>return</span> mysql_real_escape_string($_string); <span>//</span><span>这个mysql_是需要连接数据库的</span>
Nach dem Login kopieren
