In template How to print a link from a route name

Question

I would like display a link using a route name (home) into my template. How can I do with Slim Framework Thanks

My route

<?php
// index : home
$app->get('/home', function () use ($app){
   $app->render('home.php');
})->name('home');

My template

<div>
  <a href="<?php echo $this->tr("home"); // This doesn't work ?>">my home link</a>
</div>

or with urlFor()

<div>
  <a href="<?php echo $this->urlFor("home"); // This doesn't work ?>">my home link</a>
</div>

I got this message

=> Call to undefined method Slim\View::urlFor()

Answer 1

I found the solution

just add this

$app->hook('slim.before.router', function () use ($app) { 
    // Pass in the App so we can use urlFor() to generate routes 
    $app->view()->setData('app', $app); 
});

An then into your template you can use this (with app not this):

<div>
  <a href="<?php echo $app->urlFor("home"); ?>">my home link</a>
</div>

Answer 2

The Slim instance is accessible through a Singleton and its getInstance method

<a href="<?php echo Slim\Slim::getInstance()->urlFor('home'); ?>">my home link</a>

You can also specify a name if you have multiple instances of Slim

<a href="<?php echo Slim\Slim::getInstance('blog')->urlFor('home'); ?>">my home link</a>

If you want to access the urlFor method using $this

<a href="<?php echo $this->urlFor("home");">my home link</a>

Then you should create a Custom View by adding a subclass of Slim\View containing a urlFor method and link it to Slim

Custom class :

<?php
class CustomView extends \Slim\View
{
    public function urlFor($name, $params = array(), $appName = 'default')
    {
        return Slim::getInstance($appName)->urlFor($name, $params);
    }
}

Linking :

<?php
require 'CustomView.php';

$app = new \Slim\Slim(array(
    'view' => new CustomView()
));

OR:

echo '<a href="' . Slim\Slim::getInstance()->urlFor('home') . '">home</a>';
