Hello All. I am getting the "The function "baseUrl" does not exist in "main.twig" at line 29" message.

Hello All, I am getting a "The function "baseUrl" does not exist in "main.twig" at line 29". parserExtension has been enabled. Any ideas on what is wrong? The code below is where I am getting the message

<a href= "{{ baseUrl() }}" class="selected">About</a> <a href= "{{ siteUrl('/contact') }}">Contact</a>

We need either the code pasted here or a snapshot by using the camera icon on the upper right of Workspaces.

Hey Ted Sumner. I figured out what the issue was. Had to change out a few things in my index.php file. Thanks

Take a look at the code:

$view->parerExtensions = array( new \Slim\Views\TwigExtension(),

should be spelled as parserExtenstions not parerExtensions

Hey Patrick, could you post the code that you are running from the index.php file? My issue was that I had my commands out of order and thats why it couldn't recognize the baseUrl (or any of the other) functions. Try comparing it to the index.php file in the course notes and see if you can find the difference there.

so my index.php file:

<?php
require 'vendor/autoload.php'; 
date_default_timezone_set("Europe/London");

//$log = new Logger('name'); 
//$log->pushHandler(new StreamHandler('app.txt', Logger::WARNING)); 
//$log->addWarning('Foo');

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

$view = $app->view();
$view->parserOptions = array(
    'debug' => true
);

$view->parerExtensions = array(
    new \Slim\Views\TwigExtension(), 
);

$app->get('/', function() use($app){
    $app->render('about.twig');
})->name('home');

$app->get('/contact', function() use($app){
    $app->render('contact.twig');
})->name('contact');


$app->run();

?>

Thanks for checking it

greetings Patrick

$view->parserExtensions = array( new \Slim\Views\TwigExtension(), );

As Talha told, its "parser" not parer. That was the issue.
