How can I set a minimum donation amountAsked by shmoller on November 17, 2016 at 02:58 PM
I have my form for donations right now i made the oppurtunites mandatory however soemone can submit the form with the other as 0 and not have to pay. is there anyway there can be mandatory amount not 0 and if choose 0 wont go through?
Other field mandatory mandatory amount and amount
Since it is not possible to set a minimum value for the quantity option in product fields, your setup would require creating the products outside of the payment field.
First, you would delete your payment field and products. Then, you would add your donation amounts as a radio button field and assign those options calculation values:
For your "Other" option, show a number field. Number fields allow for limiting the minimum and/or maximum value entered in the field:
Make that field required and show it when other is selected:
Total everything up in a calculation field:
Then pass that total to the payment field:
I know that is a lot to take it, so I went ahead and made an example form for you:
You can clone it to your own account:
Then all you would need to do is set up the payment field and limits on the number field.
