Re: preventing users from submitting inputs twice

Hi Ned,

Maybe you can navigate away from the page and put a mechanism in place that
detects if a user allready inserted a payment record?

With kind regards,

Hi All,
>
Im my c# web project, users click a submit button for credit card payment
process.
On the web server side ( on ButtonClick_Eve nt) the user's
input(name,date ,cc number etc.) is processed and some transactional
database processes are taken based on the inputs.
>
My problem is, users may think that the button click did not work, so they
can click it again and again or they can refresh the all page by pressing
the F5 button.
And These actions can lead to two or more submissions, resulting in more
database records being added for the same payment request.

Firstly put up an immediate response along the lines of "We have
received your submission. It will take a few seconds to process.
Please do not resend yout details or refresh this page." That tells
the customer that you have got the transaction and are working on it.
Once you have finished processing then put up a "Thank you for your
custom" response. Always give immediate feedback to the customer so
they know what is happening.

Secondly keep a record of all recent transactions and query if any
duplicates come up within say ten minutes.

That does not work, that event is executed in the server, he needs
something that execute in the client.

IMHO it's just better to disable the submit mechanism.
You could also use a sort of veil control

Look at paypal. They have a button which when clicked has JavaScript to
disable the button and then post the form.

Ned,

I never will make this at single step process. At least you need a step,
wherin the user can verify what his/her input was (withouth sending of
course confidential information) and then process "the already gotten
information" with a kind of process button only one time.

(And don't forget to tell that it is processed)

Just my thought, the implementation is yours.

Hi All,

Im my c# web project, users click a submit button for credit card payment
process.
On the web server side ( on ButtonClick_Eve nt) the user's
input(name,date ,cc number etc.) is processed and some transactional
database processes are taken based on the inputs.

My problem is, users may think that the button click did not work, so they
can click it again and again or they can refresh the all page by pressing
the F5 button.
And These actions can lead to two or more submissions, resulting in more
database records being added for the same payment request.

How can i prevent users from submitting inputs twice and refreshing the
page ?

Thanks..

NED
