在codeigniter中找不到404页错误？
我刚刚开始使用codeigniter，现在正在处理我的小项目的管理控制。我有客户信息列表。
当我点击视图＆amp;编辑按钮它给我404错误
我在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>
即使删除工作也没有给我同样的错误。 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

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]

@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
$route['admin/clients'] = 'admin_clients/index';
答案 2 :(得分：0)
尝试修改更新函数以传递参数：
公共功能更新（$ id = null）
这允许您将值或null传递给函数，并将使用您的路由。
然后你需要删除它：
//product id
$id = $this->uri->segment(4);
答案 3 :(得分：0)
试试这个：
-
在
config.php中使用$config['base_url'] = ''//leave it blank;和$config['index_page'] = ''// leave it blank;。 -
将每个
<a href="'.site_url("...")更改为此<?php echo base_url("..."); ?>。 - 使用
site_url()的每个链接都将其更改为base_url()。
看看它是否有效。也许您也可以提供config.php，以便我们可以调试更多。
