现在我们来讲一下reply.php的代码: --------------------------------- //reply.php <? function check_strlen_long($txt) { $len=strlen($txt); $count=0; for ($i=0;$i<$len;$i++) { if (ord($txt[$i])<128) { $count=$count+1;} if (ord($txt[$i])==10 or ord($txt[$i])==32) {$count=0;} if ($count>=60) { $txt[$i]="n"; $count=0; } } return $txt; } function encode ($txt) { $txt=strip_tags($txt); $txt=htmlspecialchars($txt); $message=StripSlashes($txt); return $message; } $content=file("guest.txt"); $disptext=$content[$record-1]; if ($job=="addreply" and $replyname!="" and $replycontent!="") { $content=file("guest.txt"); $count=count($content); $time = date(Y年m月d日H小时i分); $ip=$REMOTE_ADDR; $replycontent=StripSlashes($replycontent); $replyname=encode($replyname); $replycontent=htmlspecialchars($replycontent); $replycontent=check_strlen_long($replycontent); $replycontent=nl2br($replycontent); $replycontent=ereg_replace(chr(10),"",$replycontent); $content[$record-1]=substr($content[$record-1],0,strlen($content[$i])-1); $content[$record-1]=$content[$record-1]."<!--reply><tr><td colspan=4><ul><font color=#AB00E1>回复内容:</font><br>".$replycontent."<br>回复人大名:".$replyname."<br><font color=#CC33FF>时间:$time 来自:$ip</font></ul><hr size=1 color=blue></td></tr>n"; $fp=fopen("guest.txt","w"); for ($i=0;$i<$count;$i++) { fputs($fp,$content[$i],strlen($content[$i])); } echo "<meta http-equiv=Refresh content=1;url=guest.php>"; exit; } ?> <title>zihanonline</title> <style> <!-- A:link {text-decoration: none ; color:0000ff} A:visited {text-decoration: none; color:004080} A:active {text-decoration: none} A:hover {text-decoration: underline; color:ff0000} BODY {FONT-SIZE: 10p} TH {FONT-SIZE: 10pt} TD {FONT-SIZE: 10pt} --> </style> <body bgcolor="#FFFFFF" background="back.gif"> <div align=center > <? include('head.htm');?> <table border= 1 width= 65% height= 169 cellpadding="8" cellspacing="0" bordercolor="#E3E3E3" > <form method= POST action=reply.php > <? if ($Submit) { if ($replyname=="" or $replycontent=="") { echo"<tr align=left valign=middle bgcolor=#F0F0F0> "; echo"<td width= 100% height= 31 > "; echo "<font color=red>出错了</font>回复人姓名和回复内容必填!"; echo"</td>"; echo"</tr>"; } } ?> <? echo $disptext ?> <tr align="left" valign="middle" bgcolor="#F0F0F0"> <td width= 100% height= 31 bgcolor="#FFFFFF" > 回复大名 <input type= text name= replyname size= 20 > </td> </tr> <tr valign="middle"> <td width= 100% height= 26 align= left bgcolor="#f0f0f0" > <p>回复内容</p> </td> </tr> <tr align="center"> <td width= 100% height= 52 valign= top bgcolor="#FFFFFF" > <textarea rows= 6 name= replycontent cols= 46 wrap="VIRTUAL" ></textarea> </td> </tr> <tr valign="middle" align="center" bgcolor="#F0F0F0"> <td width= 100% height= 14 bgcolor="#f0f0f0" > <input type=hidden name=job value=addreply> <input type=hidden name=record value=<? echo $record ?>> <input type= submit value= 提交 name=Submit > <input type=reset value= 重写 name= B2 > </td> </tr> </form> </table> <?include('bottom.htm');?> </div> </body> </html> ------------------ 到此为止,php的代码我们已经写完,剩下的是您要作一个留言本的本头和底部 您可以设计任何的样式.不过记得在本头上面要有至少3个连接:查看 返回主页 发邮件.这样您的留言本系统才算完整.不过由于这是一文本的留言本,所以您不用担心数据库的问题,您只要再写一个guest.txt的文件就完整了.虽然这个留言本没有MySQL等等,可是功能仍然不错.而且是完全属于您自己的留言本.好了,下一节我们将为您讲述guest.txt的建立和上传留言本的几个重要步骤. 未完待续...
