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

Question

<p>當我使用uri段2和3時，它可以工作，但是當我添加uri段4時，它就不起作用了。 </p><p>URL應該像這樣... http://localhost/maruf/written-qb/bcs/44th-bcs-english/how-has-the-phrase-digital-detox-been- explained-in-the-passage？ </p><p>但它顯示為... http://localhost/maruf/written-qb/bcs/how-has-the-phrase-digital-detox-been-explained-in-the- passage？而且兩個URL都顯示404。 </p><p>這是我的路由設定。</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，停用。它顯示404錯誤。</p>            

Answer 1

您的路由重疊了。

$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

請檢視文件中的註解：

註解3：

路由不是篩選器，當你使用(:any)時，它表示任何內容！為什麼第一個和第二個有效？因為您首先檢查是否為數字，對於第一個未捕獲的任何內容都會被第二個捕獲，這意味著第三個永遠不起作用。這就像是如果...否則...而不是如果...否則如果...否則...
