DataBase & Controllers code

[Emerson1220]

Hello,

I am a student and would like to retrieve information from my database to display in a view. I have been trying for 2 days without success. Here is my code:

Models -> Menu:

<?php

namespace App\Models;

use PDO;

class Menu extends \Core\Model
{
    public static function getAllMenu()
    {
        $db = static::getDB();
        $stmt = $db->query('SELECT id, dish_name, dish_content, dish_option, dish_price, dish_img FROM recette');
        return $stmt->fetchAll(PDO::FETCH_ASSOC);
    }
}

Controllers -> Menu

<?php

namespace App\Controllers;

use \Core\View;

class Menu extends \Core\Controller
{

    /**
     * Show the index page
     *
     * @return void
     */

    public $name;
    public $content;
    public $price;


    public function indexAction($args)
    {
        
        $this->$args = [];

        View::renderTemplate('Menu/index.phtml');
    }
}

Views -> Menu (phtml)

            <div class = "menu-wrapper" id="menu-wrapper">  
                <!-- Recettes -->
                <div class="starters menu-restaurant">
                    
                <?php   
                    echo 'Name:' . $args ['dish_name']; 
                    ?>                  
                </div>
            </div>

If someone to help me by telling me where the problem is coming from. I think it's from the Controllers. And how to display it in the view? Is this a return from a data table? Thanks for your help

Hi - if you're a student on the Udemy course, please ask any questions in the Q&A section there. As for your code, you need to call the model method from the controller, then pass that data to the view, e.g.

public function indexAction($args)
{
    $this->$args = [];

    View::renderTemplate('Menu/index.phtml', [
        'data' => \App\Models\Menu::getAllMenu()
    ]);
}

Then in the view the data will be available in the data variable.

Thanks for your help. I'm not a Udemy student because I don't speak English very well, but I'll fix it.

If you still have a few minutes, I just changed the code and got a Fatal error

Message: 'Too few arguments to function App\Controllers\Menu::indexAction(), 0 passed and exactly 2 expected'

The method doesn't have any arguments - try this:

public function indexAction()
{
    // $this->$args = [];
