一个传递值的问题
做了一个文章系统的上下条文章,在静态页面显示功能。结果遇到一些问题,导致在本地显示是正常的(可能本地配置要求不是很严谨,所以语法错误也可以显示),但是在服务器无法读出内容。
而且在Dreamweaver里,总是提示第四行包含一个错误语法,即

静态页面的代码是:




sxt.php的代码:

include('conn.php');
?>
if($_GET['id']=="");

($_GET['class']=="");
{}
$result=$db->query("select * from news where classid='".$class."' and id
while($row=$db->getarray($result)){
?>
document.write("

");
}
?>


{
$result=$db->query("select * from news where classid='".$class."' and id>'".$id."' order by id limit 0,1");
}
while($row=$db->getarray($result))
{
?>
document.write("

");
}
?>





求帮助,请帖代码。




------解决方案--------------------

这样的标记,需要 sxt.php 输出的是没有语法错误的 js 代码
你可以单独执行一下 /sxt.php?id=444&class=xinwen 看看都是些什么?
自己不能看出毛病的话,请贴出
------解决方案--------------------
你要贴出你js请求的url的结果数据啊。不知怎么知道你php输出什么导致了js报错。

探讨

本地读取正常。
服务器只读取最早的数据内容。即ID=1的内容
而且只读1条

------解决方案--------------------
这是什么玩意???
PHP code
if($_GET['id']=="");

($_GET['class']=="");
<br><font color="#e78608">------解决方案--------------------</font><br>($_GET['class']=="");<br>{}<br>……<br><br>{<br>$result=$db->query("select * from news where classid='".$class."' and id>'".$id."' order by id limit 0,1");<br>}<br>……<br>代码的括号没用的太多,不合语法规则。
<br><font color="#e78608">------解决方案--------------------</font><br>说的对,代码看起来有点乱啊!<br>

($_GET['class']=="");
