    are there tools available for form field verification?

    Asked by guest_22756592601052 on October 06, 2012 at 05:32 PM

    that is, if you are looking for a phone number with area code, can the form check that the phone field is properly entered even if the phone number is possibly incorrect?  force xxx-xxx-xxxx?  make sure all x's are numbers?

    Although our phone fields don't currently have number validation (possibly to allow end users the opportunity of entering word equivalents), there are a couple of alternatives at your disposal:

    * Replace the default phone field with multiple text boxes on a single line and apply numeric validation to each box

    * Replace the default phone field with a single text box, embed a copy of the form's source into a webpage and add a script to force correct entry, as demonstrated here. (Try entering letters in the phone field :)

    Please let us know if you wish to pursue either of these methods and we'll see how best we can assist you.

    phone was just an example.  i'm trying to find out if there is validation available.  i also want ot know if there are conditionals.  that is, can the fields i display be contingent on the answer to earlier fields?  simple example - i ask for cc type and they answer amex so i display xxxx-xxxxxx-xxxxx instead of expecting xxxx-xxxx-xxxx-xxxx for all other ccs.

    If you are asking for Debit/Credit Card validation then it is not possible in Jotform. We also do not allow fields that is asking for Debit/Credit Card manually, you can use any of our payment forms for this matter.
