Codeigniter 3 分页链接和单个帖子链接抛出 404

Question

我从这里阅读了其他关于此的文章，但无法解决此问题。我的问题是 2。

1. 分页显示，但点击分页链接生成404。
2. 我在 db 中有正在显示的文章列表，但是当我 单篇文章页面点击单篇文章链接，显示404。

我在 localhost wamp 上。这是我的代码。注释代码是我一直在尝试但对我不起作用的代码。

Answer 1

一个问题...

public function index($start=0)

您似乎使用$start 作为您的页码，并再次使用您的offset 值...

$data['articles']=$this->articles_model->get_articles(5,$start);

如果$start 代表您的页码，那么您不能也将它用于您的offset 值。

需要计算您的偏移量...

$offset = ($start - 1) * 5;
$data['articles']=$this->articles_model->get_articles(5, $offset);

例子：

每页有 5 条记录，第 4 页将从记录 #16 开始。所以 15 是正确的 offset 来获取第 4 页的记录 #16、17、18、19 和 20。

---

另一个潜在问题...

$config["uri_segment"] = 3;

您已将页码设置为段 3，但您的路线在段 2 处显示页码...

$route['articles/(:any)'] = 'articles/$1';

它也与此设置不匹配，这也会将您的页码放在第 2 段...

$config['base_url'] = base_url().'articles/';

基于your comment，

哇。我刚才所做的...我将$config['base_url'] = base_url().'articles/'; 更改为$config['base_url'] = base_url().'articles/index/'; 并且分页链接现在显示页面但记录没有改变。 404 消失了，页面正在发生变化 - 所有页面上的记录都是前 5 个....

那么路线应该是这样的……

$route['articles/index/(:any)'] = 'articles/$1';

所以它匹配你描述的新base_url...

$config['base_url'] = base_url().'articles/index/';
