Magento 2 – Get Quantity Dropdown for Configurable Product in Cart

configurable-productmagento-2.1

I want quantity in dropdown, I wrote code in:

app/design/frontend/Namespace/Theme/Magento_Checkout/templates/cart/item/default.phtml

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productStockObj = $objectManager->get('Magento\CatalogInventory\Api\StockRegistryInterface')->getStockItem($product->getId());
$qty = $productStockObj->getQty();
?>
<div class="field qty">
    <select id="cart-<?php /* @escapeNotVerified */
    echo $_item->getId() ?>-qty" name="cart[<?php /* @escapeNotVerified */
    echo $_item->getId() ?>][qty]" title="<?php echo $block->escapeHtml(__('Qty')); ?>" data - cart - item -
            id="<?php /* @escapeNotVerified */
            echo $_item->getSku() ?>">
        <?php for ($i = 1; $i <= $qty; $i++): ?>
            <option value="<?php echo $i; ?>"<?php if ($i == $block->getQty()) {
                echo 'selected';
            } ?>><?php echo $i; ?></option>
        <?php endfor; ?>
    </select>
</div>

But in cart page only simple product quantity showing, but configurable product not showing

Best Answer

This will work for simple products for configurable product you have to pass child product as parent do not have quantity (quantity is manage for child product in case of configurable proudcts)

check this on how to get child of Configurable product

load vendor\magento\module-checkout\view\frontend\templates\cart\item\default.phtml in you theme

Create instance of StockStateInterface to get quantity of product.

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$StockState = $objectManager->get('\Magento\CatalogInventory\Api\StockStateInterface');
?>

in place of input field update the code below

  <td class="col qty" data-th="<?php echo $block->escapeHtml(__('Qty')); ?>">
        <div class="field qty">
            <label class="label" for="cart-<?php /* @escapeNotVerified */ echo $_item->getId() ?>-qty">
                <span><?php /* @escapeNotVerified */ echo __('Qty') ?></span>
            </label>
            <div class="control qty">
                <select id="cart-<?php /* @escapeNotVerified */ echo $_item->getId() ?>-qty"
                       name="cart[<?php /* @escapeNotVerified */ echo $_item->getId() ?>][qty]"
                       data-cart-item-id="<?php /* @escapeNotVerified */ echo $_item->getSku() ?>"
                     title="<?php echo $block->escapeHtml(__('Qty')); ?>" >
                    <option value="1">Select Qty</option>
                    <?php 
                    $qtyInc = 1;
                    $stock = $StockState->getStockQty($_item->getId(), $_item->getStore()->getWebsiteId()); 
                        do {
                            $selected = ($block->getQty() == $qtyInc) ? 'selected="selected"' : '' ;
                            echo '<option value="'.$qtyInc.'" '. $selected .'>'.$qtyInc.'</option>';
                            $qtyInc++;
                        } while ($qtyInc <= $stock);
                    ?>
                </select>
            </div>
        </div>

Magento – How to add quantity dropdown in cart for configurable product

This happens because the configurable product does not have minimum sale qty and a total qty.
You need to get the simple product that is represented by the configurable product and get the values from it. Try this:

$simpleProduct = null; foreach ($_item->getQuote()->getAllItems() as $simpleItem){ if ($simpleItem->getParentId() == $_item->getId()){ $simpleProduct = $simpleItem->getProduct(); break; } } if ($simpleProduct){ //work your magic with $simpleProduct }

~~I didn't test, but it seams like the way to go.~~
I've tested and this works for me. I was close. Instead of getParentId() it should be getParentItemId(). Here is the code from my checkout/cart/item/default.phtml file:

$simpleProduct = $this->getProduct();
if ($this->getProduct()->getTypeId() == 'configurable') {
    foreach ($_item->getQuote()->getAllItems() as $simpleItem){
        if ($simpleItem->getParentItemId() == $_item->getId()){
            $simpleProduct = $simpleItem->getProduct();
            break;
        }
    }
}
$stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($simpleProduct);
$min_sale_qty = (int)$stockItem->getData('min_sale_qty');
$total_qyt = (int)$stockItem->getQty();

?>
<select name="cart[<?php echo $_item->getId() ?>][qty]">
    <?php for($i = $min_sale_qty; $i <= $total_qyt; $i = $i + $min_sale_qty) : ?>
        <option value="<?php echo $i?>" <?php echo ($i == $this->getQty())? "selected=selected": ""; ?>>
            <?php echo $i?>
        </option>
    <?php endfor;?>
</select>

I'm almost sure that there is an other way of getting the simple product and avoid the foreach loop but this will do for now.

Change Quantity to Dropdown on Product Page in Magento

First thing's first:

At present your current code is re-querying the database for the inventory information on every iteration of the loop. Don't call Mage::getModel in a loop... ever
With that in mind, you probably don't want to ask Magento to get a model inside the template file either. So you probably want to add some method to your block to get the maximum quantity available in the database and then stop creating <option>s when you reach that limit.

Assuming the above is true you should create a custom module with a custom block. The template file you're currently editing should be modified to read as such:

<?php echo $this->getChildHtml('quantityoptionsdropdown');?>

Then in your layout xml (possibly local.xml) you'll have to define that alias block:

<catalog_product_view>
    <block type="yourcompany/options" template="yourcompany/options.phtml" name="quantityoptionsdropdown" as="quantityoptionsdropdown"/>
</catalog_product_view>

Notice that we used yourcompany/options there - which should map to your custom module's block class named Options. So the full class path (at least for this example) would be something like YourCompany_YourModule_Block_Options.

So this is what your block class would look like:

app/code/local/YourCompany/YourModule/Block/Options.php

class YourCompany_YourModule_Block_Options extends Mage_Core_Block_Abstract
{
    public function getStockMaximumQty()
    {
        $product = $this->getProduct();

        return $this->getProduct()->getStockItem()->getQty();
    }

    public function getProduct()
    {
        if(!$this->product){
            $this->product = Mage::registry('current_product');
        }
        return $this->product;
    }
}

Now, your template file:

app/design/frontend/base/default/template/yourcompany/options.phtml

<?php if($this->getStockMaximumQty()>0): ?>
    <? $i = 0; ?>
    <select name="quantity" id="qty">
        <?php while($i<=$this->getStockMaximumQty():?>
        <option value="<?php echo $i; ?>"><?php echo $i++; ?></option>
        <?php endwhile; ?>
    </select>
<?php else: ?>
    <?php echo $this->__('This product is currently out of stock.'); ?>
<?php endif; ?>
