Answered FormIt preventing duplicate POSTs? (i.e. eForm's protectSubmit for Evo)

  • pixelchutes Reply #1, 10 years, 7 months ago
    Scratching my head on this one, I'm sure I must just be missing something obvious... have been reviewing the FormIt docs here: http://rtfm.modx.com/extras/revo/formit and can't seem to find a way to help prevent "duplicate POSTs" similar to the way eForm: 
    &protectSubmit=`1`
    worked in Evo.

    Does anyone know if there is a way to accomplish this?

    NOTE: I should point out that I am not using the 
    &redirectTo
    parameter, successful form submissions stay on the same page. So, if anyone refreshes the page after the post, the form gets submitted twice. Before I hand-craft a solution to prevent this, I wanted to make sure I wasn't bypassing something already baked in.

      UPDATE: Never did end up finding anything "built in", but was able to write a simple hook that stores an MD5 checksum of the entire $_POST (in $_SESSION), and then compares the previous MD5 against the current hash.

      If they match, simply $hook->addError() and return false. Easy peasy. smiley

        @pixelchutes: Could you elaborate a bit more on how you did this?
