I'm trying to generate a link to a delete method using the urlFor
helper, and i am using twig extensions to utilize the urlFor method but im getting the error
Too few arguments to function Slim\Views\TwigExtension::__construct(), 0 passed in /Applications/MAMP/htdocs/eli35/src/dependencies.php on line 47 and exactly 2 expected
not sure what to include in the parameters.
Ultimately im trying to click on the delete link to delete a task.
Any suggestions, thanks in advance.
Here is the dependencies.php file.
<?php
// DIC configuration
$container = $app->getContainer();
// view renderer
$container['renderer'] = function ($c) {
$settings = $c->get('settings')['renderer'];
return new Slim\Views\PhpRenderer($settings['template_path']);
};
// monolog
$container['logger'] = function ($c) {
$settings = $c->get('settings')['logger'];
$logger = new Monolog\Logger($settings['name']);
$logger->pushProcessor(new Monolog\Processor\UidProcessor());
$logger->pushHandler(new Monolog\Handler\StreamHandler($settings['path'], $settings['level']));
return $logger;
};
$container['db'] = function($c){
$settings = $c->get('settings')['db'];
$pdo = new PDO("mysql:host=" . $settings['host'] . ";dbname=" . $settings['dbname'] . ";port=" . $settings['port'],
$settings['user'], $settings['pass']);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
return $pdo;
};
$container['view'] = function ($container) {
$view = new \Slim\Views\Twig( 'views', [
'cache' => false,
]);
$view->addExtension(new \Slim\Views\TwigExtension(
$container->router,
$container->request->getUri()
));
$view->parserExtensions = array(
new \Slim\Views\TwigExtension(),
);
return $view;
};
here is the section of the TodosController.php for my delete method
public function deleteTodo($request, $response, $args)
{
$sth = $this->db->prepare("DELETE FROM tasks WHERE id=:id");
$sth->bindParam("id", $args['id']);
$sth->execute();
$todos = $sth->fetchAll();
return $this->response->withRedirect('/todos');
}
here is the route link for my delete method, its in the routes file
$app->delete('/todo/[{id}]', '\App\Controllers\TodosController:deleteTodo')->setName("deletetask");
here is todos.twig where im displaying the delete link
{% extends "templates/layout.html" %}
{% block content %}
<h1>My Todos</h1>
<ol>
{% for task in todos %}
<div class="myl">
<li><h4>{{ task.task}}</h4></li>
<small style="font-style:italic">{{task.created_at |date("m/d/Y")}}</small></br>
<a href="{{ urlFor('deletetask', {'id': task.id}) }}">Delete</a>
</div>
{% endfor %}
</ol>
{% endblock %}
