We had a developer add a custom code to certain product pages so that the user could order multiple quantities of multiple product variants all at once from one product page.
The issue is that the script takes too long to run...when you click Add To Cart it is taking 30-60 seconds or more to add all the products to the cart.
That is way too long. (see video here https://www.dipietro.biz/wp-content/uploads/2017/04/add-to-cart-slow.webm )
This is because the script is adding each product to the cart sequentially one by one instead of simultaneously.
Is this something that can be fixed?
We need the Add To Cart speed increased drastically.
I've been told that if we had access to the cart.php file that sits on BigCommerce's server we could just add some type of ajax multi array function and that would solve the problem but of course we do not have access to BigCommerce's servers.
Any help is appreciated at this point.
Thanks!
Without seeing the code, most likely the issue is that, as you mentioned, the products are being added to the cart sequentially, while also waiting for each individual add to cart request to finish before beginning the next - that is, it will add a product to the cart, wait for that product to successfully be added, and then proceed to add the next product to the cart.
Each 'add to cart' action is an individual POST request to the cart.php file. There is a challenge here in that BigCommerce will block the requests if too many of them occur within a certain time period; this is a BigCommerce security feature.
While you do not have access to the cart.php file, and while I do not know the specifics of the BigCommerce rate-limit/security feature, the best way to approach this is to determine and set a feasible max number of concurrent requests as well as a necessary cool-down period in order to maximize the number of requests to BigCommerce while also satisfying the security/rate-limit limitation.
For example, you might set up the program to concurrently add 3 products to the cart, wait 1 second, and then proceed to add another 3 products. Does this make sense?

A product in my store (e.g. a fine art print) has a base price of £20 and it has multiple customizable options (size / framing) that are added as additional items to the cart (e.g. Small [£0] / Medium [+£10] / Large [+£20] or Unframed [£0] / Framed [+£10] )
I have to do it this way because some products have more than 3 variant options (Shopify only supports 3)
These additional items that represent the customization options for the base product are added when the customer adds the base product to cart, but the additional products representing options are hidden to the customer in the cart.
At checkout however all is revealed, the base product appears with 2 additional items along with their additional prices. Not ideal but OK!
However, it occurred to me that there's nothing stopping a tech-savvy nerd from grabbing the variant ID of the additional items and sending a POST request to /cart/update.js that removes them from the order during checkout.
The customer just reloads the checkout page and they've just halved the price they have to pay!
I need to prevent this from happening.
I don't suppose there's a way to validate all the items in the cart when the customer requests the checkout page?
If that's not possible, how do other Shopify stores get around this issue?
If you are on the Shopify Plus plan there are two things you can do:
During checkout validation - use Script Editor to check the cart contents and if it's invalid, set the base product quantity and additional products to 0. This will prevent customers from checking out.
Post checkout validation - use Shopify Flow to cancel the order after it's placed and if it's invalid
But that's a lot of development, especially when you are not familiar with it, it will be hard to go through and make it work as expected (covering all edge cases). It's possible to create a such script but analysis of all possible scenarios and writing a code for it will take some time. If I were you I would consider an app that creates bundles as a single item. Adding such a bundle to the cart takes a few seconds to process as the app is making some admin API calls in the background but it solves your problem. I cannot promote any paid solution on StackOverflow but you will easily find something - there are plenty of solutions in the app store.
The decision comes down to your estimation + possible change requests and fixes vs. the cost of the app on a yearly basis
For our Spartacus project, we need to introduce additional Data properties in the checkout:
We have the case, that the user needs to select a delivery mode per product.
In an ideal world, upon selection, the selected delivery mode would be saved in the NGRX Store and also in the Backend to stay within the principle of the data binding defined here: https://sap.github.io/spartacus-docs/connecting-to-other-systems/#component-data-binding
Expected Data / User flow:
User goes to Checkout and to Delivery Mode Step
Custom OCC Call is made to load the supported delivery modes for each product (depends on product type and further customer specific logic)
The cart items are displayed, enhanced with a dropdown containing the available delivery modes
The user selects a delivery mode
The selected delivery mode is stored on the cart entry within the NGRX Store and saved in the backend
The new Cart totals is calculated based on the costs of the selected delivery mode
The new Cart totals is stored on the cart within the NGRX Store and saved in the backend
The user clicks on continue to get to the Review Order Step
The cart items are listed with the previously selected delivery mode
After some analysis of the existing code, we found a property deliveryMode on the orderEntry. This does not seem to be used anywhere in spartacus, but could be used to make Step 9 work by following this stackoverflow answer and this one.
Questions regarding this flow:
How can we extend the NGRX Store? We assume, it would be possible to just extend the facade (Active Cart Service), bypass the store and save the information in the backend (Described here) and afterwards refresh the store from the backend. Is that Assumption correct? If yes, that feels awkward though, as we need to reload the whole store just to contain the new property deliveryMode on the orderEntry
How can we hook into the price calculation of the cart totals to update the total based on the selected delivery mode? And again, how can we bring the new total sum into the store?
There seem to be several Answers within the Slack Channel without very few usable answers around extending the ngrx store, even though for us, it seems to be a quit normal task.. :-/
Any thoughts, inputs or support would be very appreciated. :-)
This seems like a difficult thing to accomplish seeing as delivery modes per product aren't supported as-is in spartacus. But some ideas:
You can extend core CartEntry classes (adapter, connecter, facade, etc.) to include the delivery mode for entries added to the cart. You will probably need to change all to include the delivery mode setting(s). All of these are exposed so you can modify them as needed including the store.
Utilizing multiple carts to have a product per cart and set delivery mode that way. But this would be cumbersome in my opinion.
As far as price calculation goes, I'm assuming OCC calls return total prices. Does the call for the cart entries include delivery mode costs per entry?
We have implemented the following work around and it works so far:
Enhance the Cart Model in the backend
Add new Endpoints to load the available delivery Modes per Product (by bypassing the NGRX Store)
Add new Endpoints to save the selected Delivery Mode (by bypassing the NGRX Store)
After Save Endpoint, a cart Reload is triggered, which loads the new cart totals having a custom property on the order entry (via type augmentation) into the store from the backend
It's already a lot of years past since Spartacus project started, but looks like it's still really raw projects. Spartacus is not ready to deal with real word customer's requirement and complexity of customize it quickly grow at real project(so you start to think do we really need it, as it's so unflexible at some dimentions). Some parts is really hard or not possible to customize, so you begin to search a workarounds(This question is one common case).
I think NGRX Store is one of the biggest pain in the ass to customize something at Spartacus. 2 years past and nothing changed by Spartacus team...
I'm trying to code a solution for a client, that doesn't wish to use apps. We need to be able to limit one of our products, so there only can be one of it in cart at a time.
Is there an easy way to achieve this without an app?
I'm fairly known in JS, HTML and basic liquid solutions. Is it possible to create a pure liquid solution or do we need javascript aswell? The store use ajax cart, which we need to keep.
Thank you,
Magnus
Any time you have a call to add to cart, ensure the quantity is 1
Any time you have a call to add to cart, first ensure that item is not in the cart
When you render the cart, take all the inputs for updating the cart away. Allow only delete.
With that, you can hope that for the most part, customers will only ever have one of something in the cart.
You can then focus on removing any ability to change the quantity when adding to cart, and ensuring that when checkout is selected, items do in fact only have a quantity of 1.
No Apps needed.
All I'm wanting to do is track sales of certain products from a certain date. My company is wanting to add a banner to track sales goals for raising money for charities. So basically, we'd tag a few products as being part of that goal, set a goal, and then need to update the goal progress by a certain amount every time a sale is made on one of those products. As far as I can tell, without access to Shopify's analytics API, this is not possible. How can I do this?
What you want to build is perfectly possible. However, you need to generate Private App Credentials, so you can use Shopify API. It doesn't matter if you have an account by yourself, someone else can follow these steps and send you the credentials your way.
If you don't actually need to modify anything through the API, you could have them set a webhook (Settings -> Notifications -> Webhook) on Order Creation (or similar) that posts to your server and you can check what product got sold and see if it has got the tag.
The "easy" way to do this is to create an app that receives order webhooks and can check on tagged products and keep a sum of target items sold.
Then the app should have use a script tag to insert a simple script with the current value into the web page at a configured place by css selector
OR the app could update one or more snippet files that you could include until the promo is done.
I'd tend to go with the script tag option since that's a bit more flexible and you should be able to change your theme when the promo is over to report results without having to touch the app again.
on my website I sell unique items. I have programmed it so that on the selling page, users can select any amount of these items, and it calculates the cost. The key is that I only have 1 of each of these items. So I need the shopping cart system to not allow the payment to go through unless it is available.
I've been searching for a good quick/easy/cheap solution and can't find one. I don't expect this site to make a lot of money (the transactions are a few bucks), so I didn't want to need a ssl certificate.
The only way I know of not needing an ssl certificate would be to use paypal or google checkout. However, I do not think there is a way of using these services and making paypal's server run a script to check how many are available on the site. Any solution?
Thanks
I was thinking about it more, and I think the problem is that once the user gets to the paypal payment screen, I have no control. I guess I could do something like they click the buy it now link, a php script updates it to sold, then they go to the paypal screen, but then they might not continue the purchase...
If you use PayPal Website Payments Standard (using a cart rather than 'Buy Now' Buttons) then you could use IPN or PDT (see the paypal docs here) to get PayPal to call back to you with the status of the payment.
The work flow would then be to set status to reserved when the item is added to the cart, and then wait for the IPN/PDT call to come back with the payment status, and mark the item as sold.
You would still need to check and reset to available any item that had been reserved for longer than say 2 Hours. (You could do this before serving a page to a user so that they have the latest availability and you don't need a cron job or long running process)
If you could provide a little more information about how you have implemented ur shopping card, it would have been more easier for other to assist! If you are using any ecommerce solution then it should be there already in the track inventory section. But Provided that you have implemented d shopping cart manually, why don't you add little bit of codes that checks the inventory status first before letting your customers check out?
