Is It Possible To Make Add To Cart Minimum Unit .5 Like: 1.5 Units

[AATECH]

I Am Trying To Make The Site Go By Yards, Customers Should Be Able To Purchase Like 1.5 or 1 and 1/2 Yards?
The Prices Vary For Different Fabrics.

I'm Thinking If They Could Put 1.5 In The Quantity or if there Could be a DropDown box That Shows 1/2 In It. That's Doable in Attributes But Then I have To Enter Two Prices Each time. Like If One Item Is $5 A Yard, I Need To Make The 1/2 In The Attribute to $2.50 And Etc For All The Different Prices.

So Any Help Or Opinion Is Definitely Appreciated.


Thanks in Advance.

Yes, you can have .5 as a minimum.

Thank You For Replying.

Doesn't Seem To Work. I Changed The Minimum Value to 0.5

I get This Error When I Try To Place An Order:


Please update your order ...
Product Name: Blue Dalmations on Cream ... Quantity Units errors -
You ordered a total of: 0.5 Min: 0.5

Try changing /includes/functions/functions_general.php

from this:

// replacement for fmod to manage values < 1
    function fmod_round($x, $y) {
      $i = fmod($x*1000,$y*1000);
      return $i;
    }

to this instead:

// replacement for fmod to manage values < 1
  function fmod_round($x, $y) {
    $zc_round =(int)(strval($x)*1000)/(strval($y)*1000);
    $multiplier = $zc_round * $y;
    $results = abs(round($x - $multiplier, 6));
    return $results;
  }

Thank you for the fast reply.

It's still not working. It doesn't give the error anymore but it rounds .5 to a 1 anyway.

Here's the link to the product I'm trying it on: http://www.fabrichotel.com/index.php...roducts_id=670

Thanks Again.

Admin->Configuration->Stock ... what is your setting for "Product Quantity Decimals" ?

[AATECH]

I Have The Option 1 Selected for "Product Quantity Decimals"

Now I See That In The Cart, It Shows the subtotal as half the actual price and total as full price of 1, and when you actually checkout it's back to the price of Quantity as 1 and not .5

See below for pictures:

DrByte Anymore Suggestions? or Anyone who could help?

Thanks.

What are your mininum and unit settings for this product?

What happens if you switch to Classic Template, does it make a difference?

zencart version 1.3.6
product minimum: 0.5

i also changed the code DrByte referenced to eliminate the cart errors.
