PHP+TEXT留言本(一)

來源:互聯網  2008-12-28 07:39:49  評論

大家知道,數據庫對于網絡來說的重要性.由于cgi的複雜,現在asp和php+mysql已經成爲主流.幾乎所有的個人網頁都要用到留言本,可是申請的留言本很不穩定.這爲網上的交流帶來了諸多不便.所以,希望擁有自己的留言本的朋友越來越多.

但是,免費的個人主頁支持asp和php的很少.筆者現在向您推薦動站指南,(http://www.knowsky.com)支持php.這樣您便有了能夠擁有自己留言本的基礎.現在,我就通過一個文本留言本的例子來講述php的簡單使用.

首先,我們先確定,留言的幾個過程:寫留言,發送,查看.(搜索)等等.而且對于斑竹來說,管理留言本又是不可或缺的.這樣我們就不妨定位于6個php文件,1個文本文件.6個php文件分別爲:guest.php manage.php reply.php sys.php del.php edit.php,1個文本文件爲:guest.txt

先來看看guest.php的內容,你當然可以直接將下面的內容放到您的php網頁裏,請尊重作者的勞動,謝謝.

//guest.php:<?

require("sys.php");

if ($B1)

{

if ($message=="" or $name=="")

{

$errorm="<font color=red>出錯了!!!</font>姓名和留言內容必填";

}

else

$homepage=encode($homepage);

$email=encode($email);

$message=check_strlen_long($message);

$message=nl2br($message);

$guestcontent = "<tr><td><font color=#AB00E1>留言內容:</font><br><!--content>$message<!--endcontent> ";

$guestcontent=$guestcontent."<br><font color=#6633FF>留言人大名:</font><!--name>$name<!--endname> ";

if ($email !="")

{$guestcontent=$guestcontent."<br><font color=#9900CC>電子信箱</font><a href=\"email]$email"."$space'mailto:$email\"><!--email>$email<!--endemail></a>"."$space";}
