Using smarty template engine with slim - php

I am trying to setup Slim Framework with the use of Smarty, but something is very wrong.
I can output the template, but it renders the template with the markers and the the data which should replace the markers. In the .tpl I have a marker {#currency#}, but this is also what is printed when I call test.php/test/1
I have this in my test.php
require 'libs/Slim/Slim.php';
\Slim\Slim::registerAutoloader();
use Slim\Slim;
require 'libs/Slim/Extras/Views/Smarty.php';
$app = new Slim(array('view', new \Slim\Extras\Views\SmartyView()));
$app->get('/test/:id', function($id) use ($app) {
$adverts = new Adverts();
$app->render('viewad.tpl', array(
'viewad' => $adverts->viewsinglead($id),
'imagelist' => $adverts->getadimages($id),
'firstimage' => $adverts->getadimage($id)
));
});
$app->run();
In libs/Slim/Extras/Views/Smarty.php I have set this:
public static $smartyDirectory = '/var/www/vhosts/xxxxx.dk/web/libs/smarty/libs';
public static $smartyCompileDirectory = '/templates_c';
public static $smartyCacheDirectory = '/cache';
public static $smartyTemplatesDirectory = '/templates';

Had an error in the array!
This fixed it:
$app = new Slim(array('view' => new \Slim\Extras\Views\SmartyView()));

Slim 4 assign twig parameters from middleware

I'm trying to upgrade my website's code from Slim v2 to v4. I'm not a hardcore programmer so I'm facing issues.
In Slim v2 I had some middleware where I was able to assign parameters to the Twig view before the route code executed.
Now I'm trying to manage the same with Slim v4 but without success.
I have a container:
$container = new \DI\Container();
I have the view:
$container->set('view', function(\Psr\Container\ContainerInterface $container) {
return Twig::create(__DIR__ . '/views');
});
I try to use this from middleware:
$this->get('view')->offsetSet('fbloginurl', $loginUrl);
But nothing append when the view rendered.
If I try to use the same from the route inside, its working fine.
Example route:
$app->get('/', function ($request, $response, $args) {
$params = array(...);
return $this->get('view')->render($response, 'index.html', $params);
});
There are two possible failures. First, the DI container may always return a new instance, thus it doesn't store the variables in the correct instance and they are not rendered in the twig template. Second, you use a different approach in your route sample. You pass the variables via your $params variable and they are given into the template by this way.
So you may store $this->get('view') in a variable or pass the variables as the third parameter of $params.
EDIT: You could also check, if your variable in your DI\Container already exists and then just return the instance.
So this is a test code:
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Server\RequestHandlerInterface as RequestHandler;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Routing\RouteContext;
require 'vendor/autoload.php';
require 'config.php';
lib\Cookie::init();
$container = new \DI\Container();
$container->set('view', function($container) {
return Twig::create(__DIR__ . '/views');
});
$container->set('flash', function ($container) {
return new \Slim\Flash\Messages();
});
$container->get('view')->getEnvironment()->addGlobal('flash', $container->get('flash'));
AppFactory::setContainer($container);
$app = AppFactory::create();
$app->addErrorMiddleware(true, false, false);
$fb = new Facebook\Facebook([
'app_id' => '...',
'app_secret' => '...',
'default_graph_version' => '...',
]);
$beforeMiddleware = function (Request $request, RequestHandler $handler) use ($fb) {
$response = $handler->handle($request);
if (!isset($_SESSION['fbuser'])) {
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email'];
$loginUrl = $helper->getLoginUrl('...', $permissions);
$this->get('view')->offsetSet('fbloginurl', $loginUrl);
}
else {
$this->get('view')->offsetSet('fbuser', $_SESSION['fbuser']);
}
$uri = $request->getUri();
$this->get('view')->offsetSet('currenturl', $uri);
return $response;
};
$app->add($beforeMiddleware);
$app->get('/test', function (Request $request, Response $response, $args) {
$oViewParams = new \lib\ViewParams("home", "", "", "", "");
$oProfession = new \models\Profession();
$oBlogPost = new models\BlogPost();
$oBlogTopic = new models\BlogTopic();
$professions = $oProfession->getProfessionsWithLimit(14);
$posts = $oBlogPost->getMainPagePosts();
echo $this->get('view')->offsetGet('fbloginurl');
$params = array('professions' => $professions,
'posts' => $posts,
'viewp' => $oViewParams->getMassParams());
return $this->get('view')->render($response, 'index.html', $params);
});
$app->run();
When I use echo $this->get('view')->offsetGet('fbloginurl'); within the middleware it shows up. When I use the same within the route there is nothing show up...

how to add twig-view in slimframework v4

I'm trying to add twig-view in slim v4
In slim v3, we add twig-view in container
$container['view'] = function ($c) {
$view = new \Slim\Views\Twig('path/to/templates', [
'cache' => 'path/to/cache'
]);
// Instantiate and add Slim specific extension
$router = $c->get('router');
$uri = \Slim\Http\Uri::createFromEnvironment(new \Slim\Http\Environment($_SERVER));
$view->addExtension(new \Slim\Views\TwigExtension($router, $uri));
return $view;
};
but I can't add twig like that in slim v4
Update: Twig-View has reached a stable version and the docs are updated to address Slim 4 integration.
If you are still using an unstable version of Twig-View, please consider upgrading.
First, you need to add Twig-View package to your project:
composer require slim/twig-view
And assuming the following directory structure:
composer.json
cache/
public/
|--index.php
templates/
|--hello.twig
vendor/
|--autoload.php
The followings are two working examples:
If you use a container (which is optional according to Slim 4 docs), you can add Tiwg creation definition to the container and use it when required. (I'm using php-di/php-di in this example, but you can use any PSR compatible dependency container.)
index.php, using a container:
<?php
use DI\Container;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/../vendor/autoload.php';
// Create Container
$container = new Container();
AppFactory::setContainer($container);
// Set view in Container
$container->set('view', function() {
return Twig::create(__DIR__ . '/../templates',
['cache' => __DIR__ . '/../cache']);
});
// Create App
$app = AppFactory::create();
// Add Twig-View Middleware
$app->add(TwigMiddleware::createFromContainer($app));
// Example route
$app->get('/hello/{name}', function ($request, $response, $args) {
return $this->get('view')->render($response, 'hello.twig', [
'name' => $args['name']
]);
});
// Run the app
$app->run();
You can also skip the container creation, but in that case you need to create the Twig instance before trying to render a template.
index.php, without a container:
<?php
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/../vendor/autoload.php';
// Create App
$app = AppFactory::create();
// Create Twig
$twig = Twig::create(__DIR__ . '/../templates',
['cache' => __DIR__ . '/../cache']);
// Add Twig-View Middleware
$app->add(TwigMiddleware::create($app, $twig));
// Example route
// Please note how $view is created from the request
$app->get('/hello/{name}', function ($request, $response, $args) {
$view = Twig::fromRequest($request);
return $view->render($response, 'hello.twig', [
'name' => $args['name']
]);
});
// Run the app
$app->run();
hello.twig:
Hello {{ name }}
Now try visiting /hello/slim4 in your browser and the output will be:
Hello slim4
SlimTwigView is at 3.0.0 beta (at least as of October 12, 2019), and some things have changed. The few online tutorials I've seen, as well as the official documentation no longer work.
TwigMiddleware no longer takes an instance of the $container as an argument, so you must first put Twig on the Container manually such as:
$container->set('view', function() {
// Of course put correct path to your views here
return new Twig('../views', ['cache' => false]);
});
You then you can add TwigMiddleware to your Slim App using the class' new createFromContainer method, like so:
$app->add(TwigMiddleware::createFromContainer($app));
// which is equivalent to:
// $app->add(TwigMiddleware::createFromContainer($app, 'view'));
At that point, you can render a Twig view like so:
$app->get('/', function (Request $request, Response $response, $args) {
return $this->get('view')->render($response, 'home.twig');
});
When using the Slim specific middleware, you now have access to the additional Twig extensions:
url_for
full_url_for
is_current_url
current_url
get_uri
Well! In my case I was using Slim 4.0 and Twig ^2.5. All I added to my code was
$container->set('view', function () use ($container) {
$view = new \Slim\Views\Twig(
__DIR__ .'/Templates'
, [ 'cache' => false ] //you can turn on caching by providing string path to cache or set to false
);
return $view;
});

Set template directory using Slim Framework 3

Using Slim Framework 2 you could set the template directory using this code:
// Views
$view = $app->view();
$view->setTemplateDirectory('../app/views');
How can I do this using Slim Framework 3?
Currently I'm getting this error:
Fatal error: Call to a member function setTemplateDirectory() on null
Does anybody know how to do this in Slim Framework 3?
You can do it using a \Slim\Container instance:
// Create container
$container = new \Slim\Container;
// Register component on container
$container['view'] = function ($c) {
$view = new \Slim\Views\Twig('your/path/to/templates');
$view->addExtension(new \Slim\Views\TwigExtension(
$c['router'],
$c['request']->getUri()
));
return $view;
};
Then you can use it:
$app = new \Slim\App($container);
// The route
$app->get('/foo', function (ServerRequestInterface $request, ResponseInterface $response) {
return $this->view->render($response, 'index.html', [
'name' => 'name'
]);
});
$app->run();
Check the official documentation (Mika Tuupola's suggestion).

Using a RouteCollectionProvider in Silex

I have a custom Silex\RouteCollection which I want to register...
class RouteCollectionProvider extends RouteCollection
{
public function __construct() {
$this->add(
'Index',
new Route('/', array(
'method' => 'get',
'controller' => 'index',
'action' => 'index'
)
));
}
}
...during the bootstrapping:
$app = new Silex\Application();
/** here **/
$app->run();
I could use:
$app = new Silex\Application();
$routes = new RouteCollectionProvider();
foreach ($routes->getIterator() as $route) {
$defaults = $route->getDefaults();
$pattern = $route->getPath();
$callback = 'Controller\\'
. ucfirst($defaults['controller'])
. 'Controller::'
. $defaults['action']
. 'Action';
$app->get($pattern, $callback);
}
$app->run();
I don't like having the initialization of those routes right in there.
Do you know any spot in Silex, where this does fit better?
I cannot use $app->register() because it's getting called too late and the routes won't get active in there.
Maybe there is an event I can use with
$app->on('beforeCompileRoutesOrSomething', function() use ($app) {
// initialize routes
}
Or a hook in the Dispatcher?
My aim is to not have a big collection of $app->get() or $app->post() in there. I also know I can ->mount() a controller but then still I have all my get definitions in my bootstrap and not in a Provider.
This post solves the problem: Scaling Silex pt. 2.
$app = new Application;
$app->extend('routes', function (RouteCollection $routes, Application $app) {
$routes->addCollection(new MyCustomRouteCollection);
return $routes;
});
$app->run();

Setting default assigns with slim using smarty

I am about to convert a site to use the Slim Framework with the Smarty template engine.
On the current site I have assigned some default smarty vars, but I am not sure how to set them with the Slim framework, so they are set only once.
This is how they are now:
$smarty->assign("fid", $user_profile["id"]);
$smarty->assign("fid_name", $user_profile["name"]);
$smarty->assign("fid_email", $user_profile["email"]);
$smarty->assign('postzip', $users->find_zip_or_post_new($user_profile["id"]));
$smarty->assign('userzip', $users->find_my_zip_code($user_profile["id"]));
$smarty->assign('url', $url);
$smarty->assign('catlist', $adverts->getcategories());
And this is my to-be index.php
/***
* This is the script that will generate the complete site
*/
include_once("includes/classes/class.config.php"); //Configuration file
/*
* Include the Slim framework
*/
require 'libs/Slim/Slim.php';
\Slim\Slim::registerAutoloader();
use Slim\Slim;
/*
* Include the Smarty template view
*/
require 'libs/Slim/Extras/Views/Smarty.php';
/*
* Set new Slim object
*/
$app = new Slim(array(
'view' => new \Slim\Extras\Views\SmartyView(),
'debug' => true,
'log.enable' => true,
'log.path' => 'logs/',
'log.level' => 4,
'mode' => 'development'
));
//Ad view
$app->get('/', function() use ($app) {
$adverts = new Adverts();
$view = $app->view();
$app->render(
'index.tpl',
array(
'adverts' => $adverts->listadverts()
)
);
});
$app->run();
Should I set them in the SmartyView render function
public function render($template) {
$instance = self::getInstance();
$instance->assign($this->data);
return $instance->fetch($template);
}
Fixed it by using
$app->hook('slim.before.dispatch', function () use ($app) {
});
