Timeout on submit after form is open for a long time

  • Hi,
    Thank you for a great plugin and for the support.
    I have a form that takes about 2 hours to feel (it’s a kind of an interactive lesson, and has a few different pages to it).
    Users had encountered a time out problem (or error 502) on submission after having the form open for a long time.
    Is there a way to fix it?
    Maybe to define a different timeout?
    I’m using Style = ‘Redirect’ option for the confirm URL. Will using a different option help?

    The caching configuration is on, timeout 5, Reset Form Cache unchecked.

    Here’s a link to the form:

    Thanks,
    Dana

    I cannot think of a way to fix that off the top of my head. There is some control over the HTTP API timeout on the Advanced Settings page (Dashboard > Settings > Google Forms – Advanced Tab) but I am not sure it would help here. It is certainly worth a try.

    How many pages and questions do you have on your form? As you move from page to page, the answers to prior questions are stored in hidden form variables (Google does this automatically, it isn’t a function of the plugin per se) so if you are capturing lots of data, the size of the stored data could get very large and more importantly, the size of the submitted HTTP POST request could exceed server limits. There isn’t a hard and fast limit, there is one and it varies by server configuration.

    Here is an thread on Stack Overflow about the PHP limit for HTTP POST (which is how the form is submitted to Google).

    It is important to understand that on a multi-page form, each time you change pages, either forward or backward, you are submitting your form to Google. It isn’t just the final “Submit”. Data may not be submitted to the spreadsheet until the final “Submit” but it each page change is still an “HTTP POST” that Google processes.

    Thank you for your quick answer.
    At the moment a simple timeout setting did help.

    However if the problem reoccurs:
    There are 30 questions within 10 pages in the form. I don’t believe this is too mach. but if it is, should I ask my web host to set the php_value post_max_size to a higher value?
    Thanks.

    Just to clarify – does each page have 3 questions so across 10 pages you have a total of 30 questions? How many of those questions are multi-line text entry boxes?

    30 questions will result in 30 post variables plus the other overhead Google adds to the form so you’ll likely end up with about 40 post variables. Hard to say for sure if that is a lot or not as it also depends on the amount of content each post variable holds.

    The number of questions varies between 1 to 7 in each page. The total is 32 questions, but since the pages are navigated to according to some answers, the max number of questions answered in a single submission can be 26.
    None are multi-line text entry boxes.
    If it helps, here’s a copy of the form:
