Shopping Cart view, change quantity widget to select box

Question

I have two kinds of price type: price per unit and price per weight. I have managed to use hook_form_alter() to change the widget textbox to a predefined select list.

For some items it fills the selectbox with '1 piece + price', '2 pieces + price'; for other items, I use '100 grams + price', '200grams + price' and so on. The code I have used for this is below.

function kmsol_quantity_form_alter(&$form, &$form_state, $form_id) {
    //add to cart form
    if (strpos($form_id, 'commerce_cart_add_to_cart_form_') === 0) {
        // Replace the text quantity field with a select list.
        if (isset($form['quantity']) && ($form['quantity']['#type'] == 'textfield')) {

            $product = commerce_product_load($form['product_id']['#value']);
            $price   = commerce_product_calculate_sell_price($product);

            $prd_wrapper      = entity_metadata_wrapper('commerce_product', $form['product_id']['#value']);
            $field_price_type = $prd_wrapper->field_prijs_type->value();

            $weight_array = array(
                '0.1' => '100 gram ' . commerce_currency_format(0.1 * $price['amount'], $price['currency_code'], $product),
                '0.2' => '200 gram ' . commerce_currency_format(0.2 * $price['amount'], $price['currency_code'], $product),
                '0.3' => '300 gram ' . commerce_currency_format(0.3 * $price['amount'], $price['currency_code'], $product),
                '0.4' => '400 gram ' . commerce_currency_format(0.4 * $price['amount'], $price['currency_code'], $product),
                '0.5' => '500 gram ' . commerce_currency_format(0.5 * $price['amount'], $price['currency_code'], $product),
                '0.6' => '600 gram ' . commerce_currency_format(0.6 * $price['amount'], $price['currency_code'], $product),
                '0.7' => '700 gram ' . commerce_currency_format(0.7 * $price['amount'], $price['currency_code'], $product),
                '0.8' => '800 gram ' . commerce_currency_format(0.8 * $price['amount'], $price['currency_code'], $product),
                '0.9' => '900 gram ' . commerce_currency_format(0.9 * $price['amount'], $price['currency_code'], $product),
                '1' => '1 KG  ' . commerce_currency_format(1 * $price['amount'], $price['currency_code'], $product)
            );
            $piece_array  = array(
                '0.1' => '1 stuks ' . commerce_currency_format(1 * $price['amount'], $price['currency_code'], $product),
                '0.2' => '2 stuks ' . commerce_currency_format(2 * $price['amount'], $price['currency_code'], $product),
                '0.3' => '3 stuks ' . commerce_currency_format(3 * $price['amount'], $price['currency_code'], $product),
                '0.4' => '4 stuks ' . commerce_currency_format(4 * $price['amount'], $price['currency_code'], $product),
                '0.5' => '5 stuks ' . commerce_currency_format(5 * $price['amount'], $price['currency_code'], $product),
                '0.6' => '6 stuks ' . commerce_currency_format(6 * $price['amount'], $price['currency_code'], $product),
                '0.7' => '7 stuks ' . commerce_currency_format(7 * $price['amount'], $price['currency_code'], $product),
                '0.8' => '8 stuks ' . commerce_currency_format(8 * $price['amount'], $price['currency_code'], $product),
                '0.9' => '9 stuks ' . commerce_currency_format(9 * $price['amount'], $price['currency_code'], $product),
                '1' => '10 stuks ' . commerce_currency_format(10 * $price['amount'], $price['currency_code'], $product)
            );


            if ($field_price_type == 'Prijs per kilo') {
                $select = $weight_array;
            }
            if ($field_price_type == 'Prijs per stuk') {
                $select = $piece_array;
            }

            $form['quantity']['#type']    = 'select';
            $form['quantity']['#options'] = $select;
            $form['quantity']['#size']    = 1;
        }
    }

I want to do the same thing more or less on the Shopping Cart page. However, this is a view and therefore my code is not working over there.

I have tried some code but its not working at all, and I think I'm looking at it the wrong way.

This is what I have for the moment.

function kmsol_customcart_commerce_cart_order_load($uid = 0) 
{
    global $user;
    $order = commerce_cart_order_load($user->uid);
    dpm($uid);

        $order_wrapper = entity_metadata_wrapper('commerce_order', $order);

        foreach ($order_wrapper->commerce_line_items as $line_item => $line_item_wrapper) 
        {
            $product = $line_item_wrapper->commerce_product->value();
            $field_price_type = $product->field_prijs_type->value();
            dpm($field_price_type);
            $weight_array = array(
                '0.1' => '100 gram ' ,
                '0.2' => '200 gram ' ,
                '0.3' => '300 gram ' ,
                '0.4' => '400 gram ' ,
                '0.5' => '500 gram ' ,
                '0.6' => '600 gram ' ,
                '0.7' => '700 gram ' ,
                '0.8' => '800 gram ' ,
                '0.9' => '900 gram ' ,
                '1' => '1 KG  '
            );
            $piece_array  = array(
                '0.1' => '1 stuks ' ,
                '0.2' => '2 stuks ' ,
                '0.3' => '3 stuks ' ,
                '0.4' => '4 stuks ' ,
                '0.5' => '5 stuks ' ,
                '0.6' => '6 stuks ' ,
                '0.7' => '7 stuks ' ,
                '0.8' => '8 stuks ' ,
                '0.9' => '9 stuks ' ,
                '1' => '10 stuks ' 
            );          

            if ($field_price_type == 'Prijs per kilo') {    $select = $weight_array;    }
            if ($field_price_type == 'Prijs per stuk') {    $select = $piece_array;     }

            $form['edit_quantity']['#type']    = 'select';
            $form['edit_quantity']['#options'] = $select;
            $form['edit_quantity']['#size']    = 1;
        }
 }

The issue is that the quantity widget will be filled based upon the product type, so grams will remain grams and units stay units.

Well I have a products with 2 kind of prices, price per unit and price per weight. I have a field (field_prijs_type) which is a radio button. So when I add a product to the webshop, my quantity textbox becomes a drop down. The if thing is not working because tje syntax is wrong I guess.. Is this clear? — user58642, Mar 4, 2016 at 20:16
Better to add such details in your question (edit it and be as detailed as possible), then request moderators to reopen the question. As for a push in the right direction. Drupal radio options (as any other option on a multi-value field have a system name and a user friendly name). You should be looking for the system name. Further $form_state['values'] is only available after form submission or after an AJAX callback. I see neither of those in your code so it is probably not (yet) defined. — Neograph734, Mar 4, 2016 at 20:56
I have changed my opening post to be more clear now. My first issue is resolved meanwhile, I'm only having issues with the cart view. Would you reconsider opening this topic? @kiamlaluno thanks in advance — J. Mi, Mar 6, 2016 at 9:10

I found the solution So i'll share it if someone else needs it..

hook_form_alter(&$form, &$form_state, $form_id)

        $weight_array = array(

Streamlining the above answer. To switch quantity textbox to be a select field...

function THEME_form_alter(&$form, $form_state, $form_id) {
  switch ($form_id){
    case 'views_form_commerce_cart_form_default':
      $select = array('1' => '1 ','2' => '2 ','3' => '3 ','4' => '4 ','5' => '5 ','6' => '6 ','7' => '7 ','8' => '8 ','9' => '9 ');

      foreach ($form['edit_quantity'] as $key => $quantity_field) {
        $form['edit_quantity'][$key]['#type']           = 'select';
        $form['edit_quantity'][$key]['#options']        = $select;
        $form['edit_quantity'][$key]['#size']           = 1;
        $form['edit_quantity'][$key]['#default_value']  =    $line_item[$quantity_field['#line_item_id']]->quantity;
      }
      break;
  }
}
