Module development and code questions

I am a noob working on my first module, and I've hit a wall pretty quick. I've got a controller which generates an NxM table where N and M are passed in via the url. I want to add some simple textfields to the header row of the table, but the purpose of the textfields is not for collecting data, but rather for the user to print out the table with their nicely typed header information.

If I create this in pure html, I simply add an <input> in the table cells where needed, but I'm not sure how to accomplish this in Drupal.

Please help. Thank you.

Hi,

In my project, we have 800+ categories , when visit the article edit page /node/{nodeId}/edit , this will show all categories and the page will go very long.

I'm wondering if I can add a scroll bar at the category field, so the page won't go too long, how can I do this?

Thanks!

Hello.

We have an Entity which manages some files, and we added a workflow to control the process (draft, published, archived). To keep files (for replication) we have the folder architecture tmp, files, archived that correspond to each step of the workflow.

Hello Friends.

I am trying to create shopping cart functionality via a custom module.

I send the cart items from my controller to my twig template using the following code.

MainController.php 

 // get the cart items and send them to twig template
 public function loadCart() {
        $data = $this->db_logic->getCart();

        return [
          '#theme' => 'cart',
          '#title' => false,
          '#data' => $data,
        ];
    }

cart.html.twig
