How to limit a service or product to one per order

Hello!

For one of my service that I offer on my website, I would like my customers to be limited to only 1 quantity  per order.  Basically, I don't want them to be able to press "add service" twice to the cart. How can I do that?

Furthermore, once the customer is on the checkout page, the quantity field is editable. How can I make it uneditable so that the quantity is fixed to 1 ?

Thanks ahead for your time in answering this. 

Best,

Charles

Hi,

I had same question - I do not want them to purchase more than 1 service.   

I do not know what version I have, but the instructions someone wrote for all those 'brino, etc. versions', did not work for my version but - Thank God - these steps listed below did fix it.

Home page

go to 'Commerce'

go down to 'Checkout'

go to 'Service Product Limits' and 'uncheck' this box.     yeah!  This worked for me, hope it works for you.

I'm a newer user to squarespace but I'm actually not seeing that option anymore under checkout.

The three tabs are "custom button," "custom form," and "subscription." The subscription tab does NOT have an option to limit quantity. Just how often you want to charge the customer.

Is there a new way to do this or was this feature removed?

I think you may be confusing the Checkout settings for an individual product (when adding or editing a product) with the site’s Checkout settings.  

To open the Checkout panel to change this setting:

1. Go to the Home menu
2. Click Commerce
3. Click Cart & checkout

OH! Thank you so much! Appreciate it!

I've been all through the site and it looks like you can limit quantity on services but not products? Very frustrating as we're trying to offer a promo product but it is limited to one per person. 

This might be a deal breaker for me...other carts do this, why not Squarespace?  Lame...

We are also looking to limit one product per user, why isnt this an option please?

Curious about an element of this as well. Our service products are camp sign ups and I'm trying to figure out the best way to set it up so if a parent wants to sign up 2 kids they can, but we need information no each kid. We have a custom form for enrollment, but it seems clunky to have fields for Name or names. Wondering if I can have the customer buy each enrollment as a separate item, even though they are the same sessions. That way they would buy an item for each kid even though its the same item. 

I don't think I want to globally limit services to just 1, but each item in the cart should be singular. 

Ideas? 

The solution I use is code injection via Javascript in the footer. For the specific product I want to limit to 5 items, I use the following:

document.addEventListener('DOMContentLoaded', (event) => { 
  // data-item-id = the product page's qty div
  // If someone enters more than 5, the value will revert to 5.
  // Be sure to add instructions for the qty limit in the product description.
  const quantityInput = document.querySelector('.product-quantity-input[data-item-id="6669115df767f5244f9d1f8d"] input[type="number"]');       quantityInput.addEventListener('input', () => { 
    if (quantityInput.value > 5) { quantityInput.value = 5; } 
  }); 
});

@enjoysnacks808 which footer did you put this in? When I put it in the shopping cart footer, it doesn't do anything.

Please help.

Hi I need to do this for a complimentary add-on and do not want them to be able to add more than 1. I tried this code in the footer however nothing changed. Can you please provide an update?

You can test this by adding the Complimentary add-on to cart in this product link and viewing in the cart.

  }); 
});

 

So I've added this to a code block in my products page, updated the data-item-id and I get nothing. The text that is highlighted in green in the above snippet is red in my code block so not sure if that matters. When I put the code in I am doing it in an HTML (Since I researched and found out selecting Javascript for the block is for displaying the code and not running it) block and pasting the following:

<script>

document.addEventListener('DOMContentLoaded', (event) => { 
  // data-item-id ="667b74bca548e337af44eff8"
  // If someone enters more than 5, the value will revert to 5.
  // Be sure to add instructions for the qty limit in the product description.
  const quantityInput = document.querySelector('.product-quantity-input[data-item-id="667b74bca548e337af44eff8"] input[type="number"]');       quantityInput.addEventListener('input', () => { 
    if (quantityInput.value > 5) { quantityInput.value = 5; } 
  }); 
});

</script>

I have also tried adding this to the Code Injection area of my site and still get nothing. I am allowed to enter whatever quantity I want to the cart. 

@enjoysnacks808 any ideas? About ready to put my head through my monitor lol

I just figured it out for those still wondering! (This may not be the exact way enjoysnacks808 did it in his site, but this just worked on mine)

You need to go to Website Tools>Code Injection> Footer and then paste the code snippet like this:

<script>
document.addEventListener('DOMContentLoaded', (event) => { 
  // data-item-id ="Enter your data item ID number here"
  // If someone enters more than 5, the value will revert to 5.
  // Be sure to add instructions for the qty limit in the product description.
  const quantityInput = document.querySelector('.product-quantity-input[data-item-id="Enter your data item ID number here"] input[type="number"]');       quantityInput.addEventListener('input', () => { 
    if (quantityInput.value > 5) { quantityInput.value = 5; } 
  }); 
});
</script>

For the data item ID you would enter it like this const quantityInput = document.querySelector('.product-quantity-input[data-item-id="6669115df767f5244f9d1f8d"] input[type="number"]');  where your items actual data-item-id is in " ". 

Then you would need to update the numbers in the "if" statement to the max quantity you want to be able to be selected.
 

Also make sure you have script tags <script> </script> around the code - that's what was breaking it for me. I was just pasting what enjoysnacks808 had posted and it did not work. I added the script tags and it started working.

The only issue I see with this is that yes it allows a max quantity of X (Whatever you set) to be added to the cart at a time, but I can add that max quantity over and over again. 

e.g. the code above allows for a max qty of 5, I can add 5 and then once the item is added to my cart I can then click add to cart again and it will add 5 more. I don't think there is a way to limit the amount of times an item can be added to a cart like that (at least that I have found) so while this is a step int he right direction, still not the answer to those of us that need a quantity limit enforced.

Sadly, it isn't possible to enforce maximum quantities with code. In addition to the issue with the code that you mentioned above, when a customer reaches the final checkout page, they'll be able to change the quantity to anything they like:

Yes I understand that part, it would be neat however if you could limit them to only adding say max qty 5 of one certain item to the cart when they are in the product page via the add to cart button. That would at least limit it somewhat!
