Form action not working

This is the code. When you press the submit button, nothing happens

view:

Code:

<form  method="post" action="<?php echo subSECURE;?>/index.php/User/add" autocomplete="off" enctype="multipart/form-data">
<input type="text" name="username" class="form-control" placeholder="" >
<button type="submit" class="btn btn-primary"><?= lang('Core.Dash.Add') ?></button>
</form>

Routes:

PHP Code:

$routes->post('User/add/(:segment)', 'User::add/$1',['filter' => 'auth']); 


Controllers:

PHP Code:

class User extends BaseController
{
    .... 
    public function add(){

 if ($this->request->getMethod() == 'post') {

 // SET UP RULES
 $rules = [
 'username' => [
                    'rules' => 'required',
                    'errors' => [
 'required' => lang('Core.Auth.Error.required')
                    ]
                ],
 ];

 // VALIDATE RULES
 if (!$this->validate($rules)) {
                // isError
 $data['validation'] = $this->validator;
 } else {

 // isOK
 return redirect()->to(subSECURE .'/users');
 }
 }


 }
    ... 


What is subSECURE?
You're missing a route for /User/add. It's not the same thing as /User/add/(:segment).

I tried with User/add and it still doesn't work

maybe I should put some kind of helper?
pressing the button does not execute the form at all

subSECURE is = secure.domain.com
in routers.php

PHP Code:

function whichSubRoute()
{
 $subs = array("secure" => "secure/","api" => "api/");
 $curr = $_SERVER['HTTP_HOST'];
 $curr = explode('.', $curr);
 if (array_key_exists($curr[0], $subs)) {
 return array($curr[0], $subs[$curr[0]]);
 }
 return false;
}
$choiceRoute = whichSubRoute();
if ($choiceRoute !== false) {
 if ($choiceRoute[0] == "secure") {
 ...
$routes->match(['get', 'post'], 'User', 'User::index',['filter' => 'auth']);
 $routes->post('User/add', 'User::add',['filter' => 'auth']);

 }
 if ($choiceRoute[0] == "api") {
 }
} else {

$routes->get('/', 'Home::index');

} 


pressing the button does not execute the form at all

If the submit button doesn't submit the form you must have syntax error in your html or you have some javascript code that intercept the event. Look in your browser console for any error message.

Thanks, I saw where the problem was
