We have a great connection from our server, and have hundreds of people filling out our forms a day from different ISP's, etc.</p> <p>Today we had someone who registered 15 times within a minute. I called her and she had kept hitting "Submit" over and over again because it wasn't instantly jumping to the next page. If they have a slow internet connection it may take 1 - 3 seconds to move to the "complete" page...</p> <p>What I wish is that they could have one of a couple things happen when submit is clicked:</p> <p>1. Have the submit button "grey" out so it can't be clicked again.</p> <p>2. Have some bright red text pop up above the submit button that says something like "Your submission is processing - please wait!" so they know it's being processed. </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21435 Fri, 18 Jul 2014 07:04:09 +0000 aarenhofferth 21435@https://www.machform.com/forums/ <p>After a bunch of testing, the only real variable (other than Machform itself) was the SMTP relay, which was Rackspace. I dropped the SMTP relay entirely and tested it on a different host (Media Temple) and it's been working perfectly, so my guess is it's both Rackspace and Machform. Rackspaces SMTP relay may have been slow and took extra time to send, while the the user keeps clicking the submit button causing duplicate submissions -- you should be able to edit view.js in order to remedy that problem -- just contact support directly and they can send you the file. </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21434 Fri, 18 Jul 2014 00:40:28 +0000 mjg234 21434@https://www.machform.com/forums/ <p>@aarenhofferth: Yes, I am using Rackspace SMTP server. </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21428 Thu, 17 Jul 2014 06:05:55 +0000 aarenhofferth 21428@https://www.machform.com/forums/ <p>Yeah -- I'd love an option to disable the submit button after it's clicked once. </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21427 Thu, 17 Jul 2014 05:16:26 +0000 jblackburn 21427@https://www.machform.com/forums/ <p>We have this happen quite often as well. In our case, I think it just executes slowly, so people hit the button again to resubmit. There must be some way to have it only submit once! </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21423 Thu, 17 Jul 2014 00:58:13 +0000 aarenhofferth 21423@https://www.machform.com/forums/ <p>After looking in the logs -- it appears to be a something to do with this:</p> <p>PHP Fatal error: Uncaught exception 'Swift_IoException' with message 'Connection to secure.emailsrvr.com:587 Timed Out' in /var/www/vhosts/site.com/httpdocs/form/lib/swift-mailer/classes/Swift/Transport/StreamBuffer.php:182, referer: <a href="http://www.site.com/customer-service/" rel="nofollow">http://www.site.com/customer-service/</a> </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21422 Thu, 17 Jul 2014 00:05:35 +0000 aarenhofferth 21422@https://www.machform.com/forums/ <p>mjg -- Are you using a rackspace SMTP server by chance?

Not sure what the issue is, but it started happening a few days ago (clients are on different hosting accounts).</p> <p>If I look at the time stamps, there are up to about 15 submitted within the same minute. I think it's highly unlikely that a user would submit a form that many times (they'd probably get frustrated and leave after a couple tries), let alone fill it out that quickly. My guess is that there is something with the script or the server hanging up and trying to resubmit the form over and over again.</p> <p>Any ideas guys? </p> https://www.machform.com/forums/topic/how-to-prevent-duplicate-form-submissions#post-21420 Wed, 16 Jul 2014 10:00:28 +0000 mjg234 21420@https://www.machform.com/forums/ <p>How can I prevent a user from hitting Submit multiple times and creating duplicate entries? I have created a form and the user must be hitting the back button and submitting it again or something because I sometimes get multiple submissions. One person submitted the same form 28 times in the space of about 3 minutes.</p> <p>I do not want to block the I address because I may want to allow them to submit a form again in the future. I just do not want multiple entries in a short period of time. </p>
