    How To Prevent Mulltiple Submissions Of Forms In The Same Session

    Asked by markashton on August 05, 2013 at 09:33 AM

    Hi,

    Can you advise me on how to prevent someone submitting a form multiple times because they think the form hasn't been submitted?

    I want the person to make multiple submissions over a few days ...but I don't want them to do 3 submissions in 20 seconds.

    I know about loose check and strict check ... these meet a different need ...

    The problem I am finding is that people are trigger happy and somehow manage to submit multiple times in the same session. 

    Can you advise me please on a possible workaround ... Oh the Thankyou page is very clear so don't suggest that

    Thanks Mark

    Hi Mark, I'm pretty sure I understand what you mean. It seems to me that you are seeking a medium between the two which at the moment we don't realistically have available as of right now. Because of that I will need some more time to look into this and will get back to you as soon as I can.

    I'm not seeking a medium between the two at all.

    Its just a basic requirement

    Am I to understand that there is no way to prevent someone hitting the submit button over and over again ... creating submission after submission ... unless you take away their entire ability to do more than one submission?

    Sorry about that, I misexplained what I meant to say which was that I was referring to having an option available to serve as a time-oriented controller which would allow you to set this up.

    Correct me if I'm still misunderstanding you though. To my understanding you want to set up a limitation that is time based to prevent multiple submissions within a certain amount of time is what I am thinking of after reading what you wrote.

    So for instance you have your form and someone submits it right now at say 12:30 you'd want an option to prevent resubmission multiple times until a few minutes later or longer or even the next day. There could be additional options such as to limit how many times it could be submitted.

    As far as I know we only offer the two Loose or Strict as you mentioned you already know about. I additionally meant that we don't have a feature to time this so it would mean that we would have to request it on your behalf. I think as a workaround though, this might be possible using some javascript. I'm going to continue to look into this as I mentioned before.

    Kade,

    Thanks .. you are most poilte and have a good refrain.

    You have understood me correctly ... it appears that multiple submissions can happen because someone keeps hitting the submit button ... triiger happy I suppose. 

    I have noticed multiple submissions within the same minute ... when there should only be one. If you could have a look into it .. I would be most grateful

    Thanks Mark

    I think that we have a script that is blocking the form once someone click on the submit button, but it is probably that mentioned implementation is not working 100% right on slow hardware and/or connection.

    I have attached a bug report ticket to this thread and forwarded it to L2.

    If the form takes too long to submit that might be the reason for people to re-submit. If that's the case let us know the URL of the form so that we can take a look what is causing the slowness of the submission.

    We cannot do anything about people who click on the back button and re-submit the form.

    Hi,

    Duplicate submissions are proving to be a major pain actually.

    For example ... these four submissions below were all done within 25 seconds

    I can't delete the submissions becuase the same photo is referenced by all of them .. so my client is left with the same submission four times ... not the best ... any workaround would be great ... like block by IP within 15 second intervals etc ...

     

    Hope you can help

    Thanks

    Hi Mark,

    I am not sure if "Loose Check" on Unique Submissions would be a good option for you but I was thinking it might help. This filters submissions by browser, users will not be able to submit multiple entries per browser if "Loose Check" is enabled on your form. How to Setup Unique Submissions of a Form

    If you would be so kind to provide the form URL where that problem occurs, I would be happy to add it on the report ticket for the developers to check.

    Thank you!

    Hi EltonCris,

    How exactly does a multiple submission like mine above actually happen.

    Once someone presses 'Submit' ... and the Jotform submit wheel is going round ... what exactly does the user do ??

    Many thanks

    Regards mark

    I do not know how that happened. The issue might be related to users browser, connection, hardware, some actions (like using browser back button after/during submission) or even something else. For example, the form javascript might not function the same way on different devices (browsers) due to its nature, so in theory it might not 'block' the submission button in time, and user can press the Submit button multiple times.

    I have cloned your form, integrated it with my Filepicker account. Then, I did some test submissions using my Android device to simulate your user's submission, but I was not able to reproduce any issues. I think that we will need to somehow test it further.

    So ... my projects are purely mobile ... Iphones, android, etc ....

    I get a lot of multiple submissions of forms in the same session.

    can you advise me on exactly how these happen?

    Is it where respondents press the submit button multiple time ... or is it when they click the back button when the wheel is going round.

    Is there anything at all we can do?

    Thanks Mark

    Is it where respondents press the submit button multiple time

    No, that that cannot be. The submit button does not respond to multiple clicks.

    Is it when they click the back button when the wheel is going round.

    Not quite. If they click the back button, it will take them to the form. It will not resubmit the form.

    My hunch is that these people intentionally submitted the form multiple times. The best solution for this is to delete duplicate submissions, possibly using this app:

    Secondly,

    It's nigh on useless I've just tried it. Unless you want unique names ... this hasn't been tested or thought out properly ... has it?

    Nice idea ... useless for me and my form with 700+ submissions.

    I'll start doing it manually then after that disappointment
