$route['written-qb/(:any)/(:any)/(:any)']不起作用。

Question

<p>当我使用uri段2和3时，它可以工作，但是当我添加uri段4时，它就不起作用了。</p><p>URL应该像这样... http://localhost/maruf/written-qb/bcs/44th-bcs-english/how-has-the-phrase-digital-detox-been-explained-in-the-passage？</p><p>但是它显示为... http://localhost/maruf/written-qb/bcs/how-has-the-phrase-digital-detox-been-explained-in-the-passage？而且两个URL都显示404。</p><p>这是我的路由设置。</p><p><br />></p>

<p>在控制器"writing_qb_answer"中，以及在路由$route['writing-qb/(:any)/(:any)/(:any)'] = 'writing-qb/writing_qb_answer/$1/$2 /$3';中，禁用。它显示404错误。</p>            

Answer 1

您的路由重叠了。

$route['written-qb/(:num)'] = 'written-qb';  //works
$route['written-qb/(:any)/(:any)'] = 'written-qb/written_qb_details//';  //works
$route['written-qb/(:any)/(:any)/(:any)'] = 'written-qb/written_qb_answer///';  //does not work

请查看文档中的注释：

注释3：

路由不是过滤器，当您使用(:any)时，它表示任何内容！为什么第一个和第二个有效？因为您首先检查是否为数字，对于第一个未捕获的任何内容都会被第二个捕获，这意味着第三个永远不起作用。这就像是如果...否则...而不是如果...否则如果...否则...
