Slim 3 withRedirect problem and parameters


By : Louis Mac
Date : October 18 2020, 08:10 AM
seems to work fine The second parameter of the pathFor() method is for routes with named placeholders like /users/{id}.
The 3. parameter of pathFor($name, array $data = [], array $queryParams = []) is for the query parameters.
code :
return $response->withRedirect($this->router->pathFor('root', [], ['data'=> $input]));

Difference in usage and implementation of ManualResetEvent(Slim), Semaphore(Slim) and ReaderWriterLock(Slim)

Hope that helps ReaderWriterLockSlim is a better version of ReaderWriterLock that is faster and doesn't suffer from writer starvation
ManualResetEventSlim and SemaphoreSlim are fully managed versions of a ManualResetEvent and Semaphore that spin-wait for a while before falling back to kernel objects, and so are faster than the old versions when wait times are short.

Composer autoloader + slim framework - fatal error: Class 'Slim\Slim' not found?

will help you If you prefer to keep slim under ext (as you mentioned here Slim framework - How to autoload Slim/Slim.php instead of using require?) instead of using it as a composer package, I believe this will work:
code :
{
    "autoload": {
        "psr-0": {
            "": "ext/"
        }
    }
}

Error: Slim instance must be Slim\Views\Twig, Slim\Container given

I wish this helpful for you Shouldn't $container['view'] be passed as constructor argument here, instead of $container->view?
code :
$container['loginController'] = function ($container){
    return new \App\Controllers\LoginController($container->view);
};

$response->withRedirect() method in slim not rendering global variable for twig created in middleware

will help you It's important to remember that your browser knows nothing about views, and templates, and global variables. All it sees is an HTTP response, which contains a status code, some headers, and optionally a body.
A normal response has a status code of 200, and a body containing the content the browser should display.

PHP - Displaying validation messages on a Twig view with a Slim 3 withRedirect() response

Any of those help Before the redirect, you need to save messages to the session
Before displaying the form, you need to take messages from the session.
code :
require dirname(__FILE__).'/../vendor/autoload.php';

session_start();

$app = new \Slim\App();

// Fetch DI Container
$container = $app->getContainer();

// Register provider
$container['flash'] = function () {
    return new \Slim\Flash\Messages();
};

$container['view'] = function() {
    /*
     * init your render
     */
    $view = new Render();
    return $view;
};


$app->get('/form', function ($request, $response, $args = []) {
    return $this->view->render(
        $response,
        'register.html.twig',
        [
            'register_action' => $this->router->pathFor('post_form'),
            'email_error' => $this->flash->getFirstMessage('email_error'),
            'username_error' => $this->flash->getFirstMessage('username_error'),
            'password_error' => $this->flash->getFirstMessage('password_error'),
            'old' => [
                'email' => $this->flash->getFirstMessage('old_email'),
                'username' => $this->flash->getFirstMessage('old_username'),
            ],
        ]
    );
})->setName('register');

$app->post('/form', function ($request, $response, $args = []) {
    $post = $request->getParsedBody();
    $this->flash->addMessage('old_email', $post['email']);
    $this->flash->addMessage('old_username', $post['username']);
    $email_error = null;
    $username_error = null;
    $password_error = null;
    /*
     * Your handler
     */
    if ($email_error) {
        $this->flash->addMessage('email_error', $email_error);
    }
    if ($username_error) {
        $this->flash->addMessage('username_error', $username_error);
    }
    if ($password_error) {
        $this->flash->addMessage('password_error', $password_error);
    }

    return $response->withRedirect($this->router->pathFor('register'));
})->setName('post_form');

$app->run();
