404页面未找到codeigniter中的错误？

Question

我刚刚开始使用 codeigniter，现在正在对我的小项目进行管理员控制。我有客户信息列表。

当我点击查看和编辑按钮时，它给了我 404 错误

我已经在 application/config/routes.php 中配置了路径

$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

重定向到编辑页面的代码

<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>

即使删除也不起作用，它给了我同样的错误。 这是我的 .htaccess 代码

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]

这是我的控制器文件

请帮我解决这个问题，我们将不胜感激。 谢谢

Answer 1

使用以下 .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

请更改路由条件

$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

尝试修改你的更新函数来传递一个参数：

公共函数更新($id = null)

这允许您将值或 null 传递给函数，并将与您的路由一起使用。

然后你需要删除这个：

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

Answer 4

试试这个：

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

2. 将每个<a href="'.site_url("...") 更改为此<?php echo base_url("..."); ?>。

3. 每个使用site_url() 的链接都将其更改为base_url()。

看看它是否有效。也许您也可以提供您的config.php，以便我们进行更多调试。
