Route with variable gives 404

Hi all,

I'm new to CodeIgniter and have a routing issue.
What I try to do is add a variable to the URL to pass it into the method arguments.

I used this example from the CI manual:

PHP Code:

$routes->add('product/(:num)', 'Catalog::productLookupByID/$1'); 


The actual code to match my needs is:

PHP Code:

$routes->get('/backend/profile/', 'backend/Profile::index');
$routes->get('/backend/profile/(:num)', 'backend/Profile::index/$1'); 


The method in the controller is:

PHP Code:

public function index($var = null): void
{
    echo $var;

    //some more stuff
} 


When I run the URL http://localhost:8080/backend/profile/1

I expect it to echo "1".
But instead a 404 is thrown [Controller or its method is not found: \App\Controllers\backend::index]

This controller does exist, because when I remove the 1 from the URL, the page loads, however, it is echoing NULL obviously...

What is this beginner missing here???

You have to capitalize the backend, and check your slashes

I now have copied the exact syntax including slashes, and capitailized backend as you said, but sadly it doesn't work

PHP Code:

$routes->get('backend/brands/(:any)', 'Backend/Brands::search/$1'); 


When I remove the /$1 at the end, the routing comes to the right page, but without the variable...

Hello,

could you try :

PHP Code:

$routes->add('backend/brands/(:any)', 'Backend\Brands::search/$1'); 


In the documentation you have this example :

PHP Code:

$routes->add('product/(:num)', 'App\Catalog::productLookup'); 


it's not a / but a \ I think and they use add instead of get.
If I have to use get and post i use match instead of add. with as first parameter ['get','post'].

PHP Code:

$routes->get('/backend/profile', 'Backend\Profile::index');
$routes->get('/backend/profile/(:num)', 'Backend\Profile::index/$1'); 


@sjender,

Try the most complicated route first followed by a simpler route:

// instead of this
$routes->get('/backend/profile/', 'backend/Profile::index');
$routes->get('/backend/profile/(:num)', 'backend/Profile::index/$1');

// try this
$routes->get('/backend/profile/(:num)', 'backend/Profile::index/$1');
$routes->get('/backend/profile/', 'backend/Profile::index');

PHP Code:

$routes->get('/backend/profile', 'Backend\Profile::index');
$routes->get('/backend/profile/(:num)', 'Backend\Profile::index/$1'); 


Paulbalandan is right. The second parameter must match your namespace and use backslashes.
