Magento 1.7 – Custom Options & Simple Configurable Products Fix

Magento 1.7 Price Reset to 0.00Those who recently upgraded their Magento store to Magento 1.7 may have encountered the issue of the product price resetting to zero when choosing a custom option. This error can occur due to several reasons, especially on custom themes and happens both on configurable products' custom options and that of simple products.

Price Resetting to 0.00 when Custom Option Clicked

Some Facts about the error:
  • The error is JavaScript related and occurs due to html block conflicts
  • The price change error is dynamic, hence the price is accurate when checking out
  • It occurs on any custom option types, including drop-downs, multiple select, radio buttons and checkboxes
  • The issue also occurs on simple products associated with configurable products, group and bundled products

For those who do not find the solution via the below fixes, we have implemented advanced modifications or used alternative methods that we will be publishing either for manual implementation or possibly as an extension. To get notified, feel free to register and/or subscribe:

Fix Price Resetting on Magento 1.7

If you are not using a Magento plugin for your custom options, the error would be likely theme related. If you are just starting your Magento development, I recommend using the Magento plugin Simple Configurable Products. If you intend to use the plugin or already use it, you can skip to the Simple Configurable Product Custom Options Fix. Otherwise, Here are some possible solutions to fix the custom options error on your custom theme (remember to backup files you overwrite):

  1. Updating catalog/products/view .phtml files
  2. If your base theme files are updated, you can use them to update your custom theme files by moving options.phtml, price.phtml and other theme files:

    Move the files from /app/design/frontend/base/default/template/catalog/product/view/ to /app/design/frontend/default/[yourtheme]/template/catalog/product/view/

    Some custom themes may not have the files in your product/view/ folder, yet adding them will still make Magento prioritize them if the files exist. Consider transferring the .XML files from the /layout folder as well.

  3. Editing the price_clone.phtml block
  4. Should the above option not work for you, you can also edit the price_clone.phtml block in two ways. Note that this method will only make the bottom price-block not change. So if you use custom options that change prices, or only use the top price block, this option may not be suitable.

    Via template file:

    Find your price_clone.phtml block in the product/view/ folder and find the following line:

    <?php echo $this->getPriceHtml($_product, false, '_clone') ?>
    and Replace with:
    <?php echo $this->getPriceHtml($_product, false) ?>
    Via local xml file:

    For those who prefer editing their xml layout files, they can deactivate the block instead in catalog.xml. In catalog.xml, find the bottom.phtml block:

    <block type="catalog/product_view" name="" as="product_options_wrapper_bottom" template="catalog/product/view/options/wrapper/bottom.phtml" translate="label">
    <label>Bottom Block Options Wrapper</label>
    <action method="insert"><block>product.tierprices</block></action>
    <block type="catalog/product_view" name="product.clone_prices" as="prices" template="catalog/product/view/price_clone.phtml"/>
    <action method="append"><block></block></action>
    <action method="append"><block></block></action>
    And replace the highlighted line (241) with:
    <block type="catalog/product_view_type_configurable" name="" as="product_type_data" template="catalog/product/view/type/default.phtml"/>
  5. Editing the product.js file
  6. If the above methods don't work or if you're looking for a more orthodox solution, you can change the JavaScript files themselves to work according to your theme. For this part, a well explained post has been posted here.

The last method should resolve the custom options issue and allow dynamically updating the price upon switching of options. If those don't fix the error then the issue would be theme or plugin related, which brings us to the SCP plugin fix.

Fix Simple Configurable Products Custom Options Pricing

Magento 1.7 Simple Configurable ProductsSCP is a great plugin for configurable products, which is why it's been supported by the community ever since it was deprecated. Since the last Magento update, there have been more issues than just the custom options, specifically related to the Product / Price Indexing, which I will cover on the next post.

First, confirm that the following are true:
  • You installed the most recent SCP extension on your Magento 1.7.x site.
  • Assure that the plugin works, other than the error and indexing issues (if those occur). So when you checkout, the price of the custom option is active, or if its a configurable product, that the simple product price shows up.
  • Although this is optional, I advise to copy over the plugin files from the base folder into your active template folder, if it isn't already.

Next, you will edit the plugins scpoptions.phtml file, which requires 4 small changes to fix the custom options. Open the file app/design/frontend/default/[your_theme]/template/catalog/product/view/scpoptions.phtml and make the changes to the following lines, simply by adding .price in the parseFloat:

if (this.config[optionId]) {
                    if (element.type == 'checkbox' || element.type == 'radio') {
                        if (element.checked) {
                            if (config[optionId][element.getValue()]) {
				price += parseFloat(config[optionId][element.getValue()].price);
                    } else if(element.hasClassName('datetime-picker') &amp;&amp; !skipIds.include(optionId)) {
                        dateSelected = true;
                        $$('.product-custom-option[id^="options_' + optionId + '"]').each(function(dt){
                            if (dt.getValue() == '') {
                                dateSelected = false;
                        if (dateSelected) {
			    price += parseFloat(this.config[optionId].price);
                            skipIds[optionId] = optionId;
                    } else if(element.type == 'select-one' || element.type == 'select-multiple') {
                        if (element.options) {
                                if (selectOption.selected) {
                                    if (this.config[optionId][selectOption.value]) {
					price += parseFloat(this.config[optionId][selectOption.value].price);
                    } else {
                        if (element.getValue().strip() != '') {
                            price += parseFloat(this.config[optionId].price);

After adding the .price to the highlighted lines, you can upload and replace the original which should resolve the custom options issue. Make sure to clear your cache before testing.

Other Errors

If you just started using Simple Configurable Products on your Magento install, you may encounter other unrelated issues, such as the re-indexing of flat products and prices. You can find most fixes to any of these issues from this SPC pull request on github. But the ones I found most important are:

    Hi, thank you for those fixes, it helped me a lot. But now I have a little problem wiht custom options in configurable product (CP). If I choose a custom option of CP, it works fine until the moment I select a simple product (color, for example). In that moment, price come back to ignore the custom option of CP. And if I add to cart the article, it still ignore price of custom option of CP and the custom options doesnt show up neither in the product name. I can solve it adding the custom options in each simple product associated, but it is a lot of time, and the custom options doesnt show up until a simple product is chosed. ┬┐Do you know how can I fix it? Maybe making the custom options of CP are before than choose a simple product...but I dont know hot to do it neither. Best regards.

      By using the Simple Configurable Products plugin, your configurable products will automatically go by the price of the simple products you assign it to, as well as its custom options. So make sure that the custom options of the CP is actually a Simple Product, and that any custom options are attached to that. Also make sure that you are using the second method of the above methods: Fix for Simple Configurable Products Price Reset

    Hi, thanks for your blog about SCP.... I'm having an issue with SCP, everything works fine except that when I select an item configured with the same options as a previous selected item that is already in Cart, this last item goes to the same row in the Cart and the image and SKU from the previous item is updated with the image and SKU from the new added item and the quantity on that row just increments by the number you put in the box when adding to the Cart... But in the other hand, when you do the same with Wishlist everything goes right, even when you move these items to the Cart, they go to different rows/lines.... Hope I had explain myself Thanks in advance

    I have tried nearly all fork version's from SCP, have setup a fresh magento installation and installed only SCP, but at all SCP version's it is not possible to edit configurable products after add to cart? If the customer click the product edit link in the Shopping cart, the follow message show "Cannot configure product." Have anybody the same issue?

    Hello Matt, great extension by the way. However, when I add a configurable product to a my cart, it displays the Simple product but not the configurable product even though in settings I have set show configurable product. My debugging so far. With SCP module not activated, $_POST Data below Array( product => 8 //product_id of configurable product related_product => super_attribute=> Array( 139 => 15, 140 => 18 ) qty => 1 ) But with SCP activated Array( product => 6 //product_id of selected simple product related_product => super_attribute=> Array( 139 => 15, 140 => 18 ) qty => 1, cpid => 8 ) Also checked the db Table 'sales_flat_quote_item' , the just the simple product is inserted in the table, the parent_item_id is set to NULL. Without SCP set, you line are inserted in the db Table. First the configurable and then the id used to insert the configurable as the parent_item_id field. Any solutions
