For those who are willing to use
VM Custom, Stockable Variants, then you should do this small modification.
(otherwise you won't see awesome add to cart button of PureMart)
Open this PHP file:
/plugins/vmcustom/stockable/stockable.php
Look for this line (around 403rd line):
$(".addtocart-bar").append(\'<span class="quantity-box"><input type="text" class="quantity-input js-recalculate" name="quantity[]" value="\' + quantity + \'" /></span><span class="quantity-controls js-recalculate"><input type="button" class="quantity-controls quantity-plus" /><input type="button" class="quantity-controls quantity-minus" /></span><span class="addtocart-button"><input type="submit" name="addtocart" class="addtocart-button" value="'.JText::_('COM_VIRTUEMART_CART_ADD_TO').'" title="'.JText::_('COM_VIRTUEMART_CART_ADD_TO').'" /></span><div class="clear"></div>\');
and replace it with this:
$(".addtocart-bar").append(\'<span class="quantity-box"><input type="text" class="quantity-input js-recalculate" name="quantity[]" value="\' + quantity + \'" /></span><span class="quantity-controls js-recalculate"><input type="button" class="quantity-controls quantity-plus" /><input type="button" class="quantity-controls quantity-minus" /></span><span class="FlexibleCSS3Button"><input type="submit" name="addtocart" value="'.JText::_('COM_VIRTUEMART_CART_ADD_TO').'" title="Add to Cart" class="addtocart-button FlexibleCSS3Button-text"><span class="FlexibleCSS3Button-slide-text"><span class="FlexibleProductDetailsInStock">'.JText::_('COM_VIRTUEMART_PRODUCT_IN_STOCK').'</span></span><span class="FlexibleCSS3Button-icon-right"><span></span></span></span><div class="clear"></div>\');
And you will be good to go.
You would need to do this coding modification each time you update your Virtuemart.
