Answer 1

You haven't said what Magento version

Something like this should work with Magento 1

<button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-cart" onclick="setLocation('<?php echo $this->getAddToCartUrl($_product) ?>')"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button>

<?php $product_id=$_product->getId() ?>
<?php $base_url=Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_LINK);?>
<label for="qty"><?php echo $this->__('Qty:') ?></label>
<input type="text" name="qty" id="<?php echo $product_id ?>" maxlength="12" value="1" title="<?php echo $this->__('Qty') ?>" class="input-text qty"></input>
<button type="button" title="<?php echo $this->__('Add to Cart') ?>" class="button btn-cart" onClick="addToCart('<?php echo $product_id ?>','<?php echo $base_url?>')"><span><span><?php echo $this->__('Add to Cart') ?></span></span></button>

<script type="text/javascript">
function addToCart(pid,purl)
{
    var qty=document.getElementById(pid).value;
    var action=purl+"checkout/cart/add/product/"+pid+"/qty/"+qty;
    window.location=action;
}
</script>

Answer 2

Just thought of another answer which involves no programming.

You could create a group product and assign a single product to that group.

Like this product. This is Magento 2. But Magento 1 works the same.

But with just one

Answer 3

So the current value is 0. I want to change it to 2 or higher, incase if someone (customer) put it 1 don’t allow them to add to basket

Answer 4

Okay so I believe this is what you want

• Edit a simple product
• Click Advanced Inventory
• Change 'Minimum Qty Allowed in Shopping Cart' option
