404页面未找到codeigniter中的错误？

Question

I have just started working with codeigniter, now working on admin control of my small project. I have client information list.

when i click on view & edit button its giving me 404 error

i have configured path in application/config/routes.php

$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

code to redirect to edit page

<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>

Even delete is not working its giving me the same error. here is my .htaccess code

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]

please help me to solve this problem, response will be appreciated. Thank you

Answer 1

Use the following .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

please change the routing conditions

$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

try modifying your update function to pass an argument :

public function update($id = null)

this allows you to either pass a value or null to the function and will work with your routes.

you would then need to delete this :

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

Answer 4

Try this:

1. In your config.php use $config['base_url'] = ''//leave it blank; and $config['index_page'] = ''// leave it blank; .

2. Change every <a href="'.site_url("...") to this <?php echo base_url("..."); ?> .

3. Every links that use site_url() change it to base_url() .

See if it works. Maybe you can provide your config.php too so we can debug more.
