Umbraco: 7.11.1 Tea Commerce: 3.2.4

Hi guys,

I successfully managed to display variants on my site thanks to your help.

Though, I can't seem to find a solution to updating the product price according to the selected variant.

Using the documentation I can loop through each variant price, but I'm not interested in showing all prices but rather change the one product price that is visible.

IPublishedContent productPage = Model.Content;
long storeId = long.Parse(Umbraco.TypedContent(1064).GetPropertyValue<string>("store", true));

//Main product data
var productName = productPage.GetPropertyValue<string>("productName");

IPublishedContent productImage = productPage.GetPropertyValue<IPublishedContent>("image"); ;

List<VariantPublishedContent> variants = TC.GetVariants(storeId, productPage).ToList();
List<VariantGroup> attributeGroups = TC.GetVariantGroups(productPage, variants).ToList();
string variantJson = TC.GetVariantJson(storeId, productPage, true);


                <form method="post" action="/base/TC/FormPost.aspx" class="ajaxForm" data-product-id="@productPage.Id">
                    <input name="AddOrUpdateOrderLine" value="productIdentifier, quantity" type="hidden" />
                    <input name="storeId" value="@storeId" type="hidden" />

                    <div class="product_price_area">
                        <div class="form-horizontal">
                            @{
                                var price = CurrentPage.GetPropertyValue("price");
                            }
                            @String.Format("{0:n}", price) DKK

                            @if (attributeGroups.Any())
                            {
                                foreach (VariantGroup variantGroup in attributeGroups)
                                {
                                    <div class="form-group">
                                        <label class="col-sm-3 control-label">@variantGroup.Name</label>
                                        <div class="col-sm-9">
                                            <select class="form-control" data-attribute-group="@variantGroup.Id">
                                                <option value="">Select @variantGroup.Name</option>
                                                @foreach (VariantType variantType in variantGroup.Attributes)
                                                {
                                                    <option value="@variantType.Id">@variantType.Name</option>
                                                }
                                            </select>
                                        </div>
                                    </div>
                                }
                                <input name="productIdentifier" value="" type="hidden" />
                            }
                            else
                            {
                                <input name="productIdentifier" value="@productPage.Id" type="hidden" />
                            }

                            <div id="add_product">
                                <div class="form-group">
                                    <label>Antal</label>
                                    <input class="form-control" name="quantity" value="1" type="text" />
                                </div>
                                <input class="btn btn-primary btn-block disabled" value="Tilføj til kurv" type="submit" />
                            </div>
                        </div>
                    </div>
                </form>

Hi Mike,

Do you mean just visually on the page?

Matt, you're at it again, thanks for helping me out.

It's both visually and when adding the item to the basket.

I have a shirt
In blue for $1
In red for $2
If I select the blue/red the price doesn't change visually
If I add a blue to basket and afterwards a red, the basket registers both items as 2 blue shirts at $2 in total, rather than $3.

I hope that makes sense. Perhaps it isn't possible?

Hi Mike,

I'm wondering if that later issue is because your <input name="productIdentifier" value="" type="hidden" /> is blank when looping the variants. I think in this instance you need to give each variant an SKU and that should make them show up as individual items (IIRC).

From a visual perspective, I think you'd want to use some javascript to watch the select list for a change event then update the value on the page.

You're a wizard Matt, the SKU has to be defined for it to work.

I'll do the visually representation of the prices with Javascript.

Thanks once again, Matt!

For those who might be in a similar situation, I made a quick fix for the visual price change. It's not pretty but it's a temporary fix:

First: Display all variant prices and add a index number to each price element (using data attribute)

var variantIndex = 0;
<div id="variantPrices">
    @foreach (VariantPublishedContent variant in variants)
    {
        variantIndex++;
        <div class="variantPrice" data-priceindex="@variantIndex">
            @(TC.GetPrice(1, Model.Content.Id + "_" + variant.VariantIdentifier))
        </div>
    }
</div>

Next: Remove them all using CSS:

 .variantPrice {
        display: none;
        &.show {
            display: block;
        }
    }

Last: Use Javascript to hide/show each price depending on the selected option index:

$('.form-control').change(function () {
    var idx = this.selectedIndex;
    $('.variantPrice').each(function () {
        $(this).removeClass('show');
        $(this).attr('data-priceindex') == idx ? $(this).addClass('show') : null;
    });
});
