PHP+TEXT留言本(三)

來源:互聯網  2008-12-28 07:39:46  評論

上兩節我針對guest.php和edit.php作了講述.需要注意的是php和html的區別:

php通常是-->(1)<? echo("zihanonline");?>

(2)<? php

echo("zihanonline");

?>

(3)<script laanguage="php">

echo("zihanonline");

</script>

(4)<% echo("zihanonline");%>

等4種方式.不要混淆.

下面我們來研究信息管理:manage.php代碼.

-----------

//manage.php<html>

<head>

<title>留言管理</title>

<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

<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: 9p}

TH {FONT-SIZE: 9pt}

TD {FONT-SIZE: 9pt}

-->

</style>

</head>

<body bgcolor="#FFFFFF" background="back.gif">

<?

include('head.htm');

include("sys.php");

if ($password!=$managepwd and $dispflag)

{

echo "<meta http-equiv=Refresh content=5;url=guest.php>";

echo "<center>";

echo "<font color=red>密碼錯誤!無法刪除留言!</font>";

echo "<p>程序將在3秒返回</p>";

echo "<p> <a href=http://zihanonline.longcity.net>子漢在線</a>斑竹維護管理。</p>";

echo "<br>";

echo "</center>";

exit;

}

?>

<table width="445" border="0" align="center" bgcolor="#CCCCCC">

if ($dispflag=="show")

{

$content = file($guestfile);

$count =count($content);

$text="";

for ($h=$count;$h>0;$h--)

{

$text=$text.'<tr><td>刪除第'.$h."條留言:<input type=checkbox name=check$h value=$h></td></tr>nn";

$text=$text.$content[$h-1];

}

echo "$text";

}

?>

<input type=hidden name=password value=<? echo $password ?>>

echo "<br>";

echo "</center>";

exit;

}

if ($password==$managepwd)

{

$guest_content=file($guestfile);

$count=count($guest_content);

for ($j=1;$j<=$count;$j++)

{

$del_rec_num="check".$j;

$del_num=$$del_rec_num;

//echo "$del_num:$del_num";

$guest_content[$del_num-1]="";

}

$fp=fopen($guestfile,"w");

for ($i=0;$i<=$count-1;$i++)

{

if ($guest_content[$i]!="")

{

fputs($fp,$guest_content[$i],strlen($guest_content[$i]));

}

}

fclose($fp);

echo "<meta http-equiv=Refresh content=5;url=guest.php>";

echo "<center>";

echo "<p><font color=red>留言已正確刪除</font></p>";

echo "<p>程序將在3秒返回</p>";

echo "<p> <a href=http://zihanonline.longcity.net>子漢在線</a>斑竹維護管理。</p>";

echo "<br>";

echo "</center>";

exit;

}

}

?>

<tr>

<td bgcolor="#f0f0f0">

<p align=center>

<input type=submit value=刪除 name=submit>

&nbsp;&nbsp;&nbsp;&nbsp;

<input type=reset value=重寫 name=reset>

</td>

<tr>

</form>

</table>

<?include('bottom.htm');?>

</body>

</html>
