404頁未找到codeigniter中的錯誤？

Question

我剛剛開始使用codeigniter，現在正在處理我的小型項目的管理控制。我有客戶信息列表。

當我查看&編輯按鈕，點擊它給我的404錯誤

我已經在應用/配置/ routes.php文件

$route['admin/clients'] = 'admin_clients/index'; 
    $route['admin/clients/add'] = 'admin_clients/add'; 
    $route['admin/clients/update'] = 'admin_clients/update'; 
    $route['admin/clients/update/(:any)'] = 'admin_clients/update/$1'; 
    $route['admin/clients/delete/(:any)'] = 'admin_clients/delete/$1'; 
    $route['admin/clients/(:any)'] = 'admin_clients/index/$1'; //$1 = page number 

代碼配置的路徑重定向到編輯頁面

<td class="crud-actions"> 
        <a href="'.site_url("admin").'/clients/update/'.$row['id'].'" class="btn btn-info">view & edit</a> 
        <a href="'.site_url("admin").'/clients/delete/'.$row['id'].'" class="btn btn-danger">delete</a> 
       </td> 

即使刪除不起作用給我同樣的錯誤。 這裏是我的.htaccess代碼

RewriteEngine on 
RewriteBase /testing_palace/ 
RewriteCond $1 !^(index\.php|resources|robots\.txt) 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

請幫我解決這個問題，反應可以理解的。 謝謝

Answer 1

使用下面的.htaccess：

RewriteEngine on 
RewriteCond $1 !^(index\.php|resources|robots\.txt) 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$index.php/$1 [L,QSA] 

Answer 2

@Noor Fathima

請更改路由條件

$route['admin/clients/update/(:any)'] = 'admin_clients/update/$1'; $route['admin/clients/delete/(:any)'] = 'admin_clients/delete/$1'; $route['admin/clients/update'] = 'admin_clients/update'; $route['admin/clients/add'] = 'admin_clients/add'; $route['admin/clients/(:any)'] = 'admin_clients/index/$1'; //$1 = page number $route['admin/clients'] = 'admin_clients/index';

Answer 3

嘗試修改您的更新功能將參數傳遞：

公共功能更新（$ id = null）

這允許您將值或空值傳遞給該函數，並且將與您的路由一起工作。

你就那麼需要刪除此：

//product id 
$id = $this->uri->segment(4); 

Answer 4

試試這個：

1. 在你config.php使用$config['base_url'] = ''//leave it blank;和 $config['index_page'] = ''// leave it blank;。

2. 每<a href="'.site_url("...")更改爲此<?php echo base_url("..."); ?>。

3. 每個使用site_url()的鏈接將其更改爲base_url()。

看看它是否有效。也許你可以提供你的config.php，所以我們可以調試更多。
