我为一个有 3 个不同 php 页面的网站创建了一个留言簿，在有人对留言簿提交评论后，我无法查看文本.. 这是每个的编码

留言簿.php

<style type="text/css">
body,td,th {
    color: #FFFFFF;
}
body {
    background-color: #333333;
}
a:link {
    color: #FFFFFF;
}
a:visited {
    color: #FFFFFF;
}
a:hover {
    color: #FFFFFF;
}
a:active {
    color: #FFFFFF;
}
</style>
<body bgcolor="#333333" text="#FFFFFF" link="#FFFFFF" vlink="#FFFFFF" alink="#FFFFFF">    <table width="400" border="0" align="center" cellpadding="3" cellspacing="0">
<tr>
<td>&nbsp;</td>
</tr>
</table>
<table width="400" border="0" align="center" cellpadding="0" cellspacing="1" >
<tr>
<form id="form1" name="form1" method="post" action="addguestbook.php">

<table width="400" border="0" cellpadding="3" cellspacing="1" >

<td width="117">Name</td>
<td width="14">:</td>

while($rows=mysql_fetch_assoc($result)){ .. }


mysql_fetch_array -- will always returns the indexed array.

将其更改为降序更改。

$sql="SELECT * FROM $tbl_name";

至

$sql="SELECT * FROM guestbook ORDER BY datetime DESC";

我不确定您所说的“我无法查看文本”是什么意思。这是否意味着您的留言簿 php 页面没有显示条目，或者数据库是空白的？

我不确定你为什么这样做$tbl_name = "guestbook";，但这只会让事情变得混乱。此外，您的空间到处都是，所以我不确定这是否是问题所在。

换个试试...

$sql="INSERT INTO $tbl_name(name, email, comment, datetime)VALUES('$name', '$email',     '$comment', '$datetime')";

进入

$sql="INSERT INTO guestbook (name, email, comment, datetime) VALUES ('$name', '$email', '$comment', '$datetime')";
