PHP分页-页面链接

Question

Thank you everyone who helped me yesterday with this new to me topic. 谢谢昨天在我这个新话题上为我提供帮助的每个人。 I've tried to write code myself, and it works fine for the first page. 我尝试自己编写代码，并且在第一页工作良好。 However, when I click any of the page links, I get this: 但是，当我单击任何页面链接时，都会得到以下信息：

The requested URL /headfirst_phpmysql/guitarwars/index.php&page=3 was not found on this server. 在此服务器上找不到请求的URL /headfirst_phpmysql/guitarwars/index.php&page=3。

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. 此外，尝试使用ErrorDocument处理请求时遇到404 Not Found错误。

Here is my entire PHP: 这是我的整个PHP：

Answer 1

Where is your ? 你在? in query string? 在查询字符串？ ;) ;）

And the long answer: 长答案：

The server is not requesting the index.php file but index.php&page=3 . 服务器不请求index.php文件，而是index.php&page=3 。 So it returns 404 as it's not finding anything;) 因此它返回404，因为它没有找到任何东西；）

Answer 2

The first argument suplied by GET is introduced with an ? GET提供的第一个参数以?开头? . 。 If you have multiple arguments supplied, you use the & after that: 如果提供了多个参数，请在之后使用& ：

testurl.html?firstarg=123&second_arg=456

Answer 3

Use http_build_query to construct the query string. 使用http_build_query构造查询字符串。 See the docs @ http://www.php.net/manual/en/function.http-build-query.php 参见docs @ http://www.php.net/manual/zh/function.http-build-query.php

You need to append the result to http://example.com/? 您需要将结果附加到http://example.com/? (note the ? ) （请注意? ）

Answer 4

Try to use this: 尝试使用此：

(added ? before &) （在＆之前添加？）
