route cannot be found while reverse-routing.

Hi.. i get the error mentioned in the title when i try to update a row in db. And the validation failes.
Routes.php In a group admin

Code:

//Kategorier
    $routes->get('cat/list', 'CatController::index');
    $routes->get('cat/create', 'CatController::create');
    $routes->post('cat/store', 'CatController::store');
    $routes->get('cat/edit/(:num)', 'CatController::edit/$1');
    $routes->post('cat/update/(:num)', 'CatController::update/$1');
    $routes->get('cat/delete/(:num)', 'CatController::delete/$1');

in the controller

Code:

## Validation
          $input = $this->validate([
            'kategori' => 'required|min_length[3]',
          ]);

          if (!$input) {
             return redirect()->route('admin/cat/edit/'.$id)->withInput()->with('validation',$this->validator);
          } else {

error message from debug bar

Code:

          ## Validation
83           $input = $this->validate([
84             'kategori' => 'required|min_length[3]',
85           ]);
86   
87           if (!$input) {
88              return redirect()->route('admin/cat/edit/'.$id)->withInput()->with('validation',$this->validator);
89           } else {

With line 88 marked.
Is there enough info to answer?

You have no admin/cat/edit/ route did you mean 'cat/edit/'.$id

What did you Try? What did you Get? What did you Expect?

You have no admin/cat/edit/ route did you mean 'cat/edit/'.$id

the route is in a route group...

PHP Code:

// Admin routes
$routes->group("admin", ["filter" => "auth"], function ($routes) {
    $routes->get("/", "home::index");
    $routes->get('listusers', 'User::list', ['filter' => 'auth']);
    $routes->get('viewuser', 'User::view', ['filter' => 'auth']);

    //Kategorier
    $routes->get('cat/list', 'CatController::index');
    $routes->get('cat/create', 'CatController::create');
    $routes->post('cat/store', 'CatController::store');
    $routes->get('cat/edit/(:num)', 'CatController::edit/$1');
    $routes->post('cat/update/(:num)', 'CatController::update/$1');
    $routes->get('cat/delete/(:num)', 'CatController::delete/$1'); 


When typing the adress: localhost/admin/cat/edit/1 it works fine. Its just when i try to edit and it fails on validation i get this error.
If i try to create a new using admin/cat/create it works fine... so the code below works fine...

PHP Code:

       ## Validation
           $input = $this->validate([
              'kategori' => 'required|min_length[3]|is_unique[kategori.kategori]',
           ],
           [ // ERRORS
               'kategori' => [    'min_length' => 'Kategori må inneholde minst 3 bokstaver',
                                   'is_unique' => 'Denne kategorien finnes allerede']
            ]);
  
           if (!$input) {
              return redirect()->route('admin/cat/create')->withInput()->with('validation',$this->validator); 
           } else { 


PHP Code:

//1. Named route
$routes->get('cat/edit/(:num)', 'CatController::edit/$1', ['as' => 'cat.edit']);

redirect()->route('cat.edit', [$id])

//2. Controller&method (with namespace)
redirect()->route('\App\Controllers\CatController::edit', [$id])

//3. Url
redirect()->to('admin/cat/edit/' . $id) 


Note that the withInput() method already adds validation error data.
To get errors you need:

PHP Code:

// init session (Even though it looks stupid in terms of practicality, but otherwise will not work.)
session();
// get validator instance
$validation = Services::validation();
// get errors 
$validation->getErrors(); 


Just pussled with the fact that it works under function store() but not in update() in the same controller.

Here is the full CatController.php

Line 38: Works fine
Line 91: Fails

PHP Code:

<?php

Because the route is not 'admin/cat/edit/1', but 'admin/cat/edit/([0-9]+)'

Because the route is not 'admin/cat/edit/1', but 'admin/cat/edit/([0-9]+)'

Not sure if I understand... Is there something i can do to fix it ?

Fix what? Everything works fine.
I showed above how to get out of the situation in three ways.

But if you want to change behavior, you can offer your PR.
