我一直试图建立一个网站。这是一个在线购物网站。

“新产品”和页脚部分不来了，我不知道为什么。我还没有网络主机，所以我现在正在使用本地主机。我曾尝试编辑代码，但是无论如何，它似乎都无法正常工作。如果有人可以提供帮助，我将不胜感激。谢谢。

/* require_once('dbconnect.php'); */
$result = mysql_query("SELECT * from product WHERE brand='accessories'");
正如我在评论中所说，您多次使用此require_once('dbconnect.php');，而在文件顶部仅应使用一次。
上面的代码是我第一次发现，正如它被注释掉的那样，该查询将轰炸您。执行从上到下进行，第一个未提交的发生是第196行，这对第一个查询来说是很晚的方式。
就像我在评论中所说的
尝试打开错误报告-
error_reporting(-1);和ini_set('display_errors', '1');将它们放在<?php标签之后
您可以节省自己，这样我们可以节省很多时间。
所以在夏日，
删除所有这些require_once('dbconnect.php');，然后在打开的<?php标签之后添加一个。
PS，只需注释掉第一个查询，或者取消注释第一个require_once，就可以轻松地进行测试。
