Validate a checkbox

On a registration form, I have a checkbox which I want the user to tick to agree to terms. The box is required to be ticked so I would like an error message to come up if it remains unticked on submission. How do I go about doing this correctly?
Many thanks

make sure that the check box has a checked value.

edit the Server Validation Server behavior, select the Required / not blank validation type.

for the server variable, click the lightning bolt and select the checkbox, then click the plus button to add it to the list of validations.


in design view, type the error message next to the checkbox, and select it.

go to webassist -> Forms -> Validation -> Validation Show If

from the list of validations, select the required validation for the checkbox, then click the plus button to add it to the failed list and click ok.

Many thanks Jason

Hi,

I was searching through and found this thread to be the closest to my question. How can I ensure my protection if someone comes back and claims he did not agree to the terms and since I would have access to the database I put in the 1 or what ever value the check box puts into the database field.

1. Is there a secure way or system big companies use that proves the checkbox came from that website visitor? Any suggestions would make my paperwork less.
2. My best thought, can a field in the db be made to only accept the 1st input value and no changes.

thanks

you should use Server Validation to ensure that the checkbox is checked.


By preventing the form from submitting unless the checkbox is checked, the very fact that the record is in the database is proof that user agreed to the terms.

Set the checked value of the Agree checkbox to 1, and use Required not Blank validation to make sure it is checked.

if it is not checked, the form cant be submitted, and the registration record will not be saved.

Thank you for the reply. However, what if the user states he did not submit and agree to it and would it not be possible for me to simply fill out the db record manually?
I have been wondering for an answer on this for a while, because I would like to make things paperless, but need it to be failsafe if ever the user wanted to stir trouble.
Or what if the user doesn't say the truth and says the policy is different than what he checked.

I am only trying to be proactive before going paperless,

thanks

in the registration, you can record the IP of the user who fill in the form, sure, you could fill in the record on the database but you would need to know the IP address.

you should also be recording the registration date in your database.

These questions would really be best posed to a lawyer however.
