InfoPath Dev

Hello, 

I have a SharePoint 2010 site with anonymous access, and inside the site pages there is published InfoPath 2010 forms, how can I add CAPTCHA to these forms?

Any kind of help will be highly appreciated

Here is a sample form - IP 2007 filler - that uses a free web service for CAPTCHA - the submit button doesn't do anything but is disabled unless the response is correct - save it locally, right click and select Design to open and preview to test the functionality. There may be other free CAPTCHA web services - this should at least give you some ideas to try. :-) EDITED TO ADD: The service used in this sample form is being shut down, so I've removed the sample.

 Hi Marko, try to read this http://distinctcaptcha.codeplex.com/

 

Hilary,

 thank you very much, for me it is very helpful :)

Thanks Hilary it works for me :)

Just an FYI to anyone who may come across this thread - the original sample used a service provided by TextDisguise that will be shut down at the end of January 2018.

Hi Hilary , Do you have idea if i can find some other web service same as textdisguise Web service . As i am using this Captcha in one of internet site for the client , where i cannot use codeplex captcha , because i cannot publish codplex Captcha service to be accessible over the internet. Thanks in advance .

 I did some quick looking around on the web, and I'm not finding anything right off... are you using this in InfoPath, as per the sample? Can you maybe implement Google's recaptcha API instead? I found a pretty straightforward tutorial here: https://codeforgeek.com/2014/12/google-recaptcha-tutorial/

Thanks for time . I went through tutorial and various articles about google ReCAPTCHA API and found that it cannot be supported in infopath based forms. the client is having internet facing site , where CAPTCHA plays an important role against Spams Protection. I can easily use Distinct CApcha Instead , but my only problem is i cannot publish distinct CAPTCHA webservice . It works well locally but for internet user the picture may not appear until we publish the web service .. Any solution for that .

 I should have been more clear - I was wondering if you could use something OTHER than InfoPath - I suggested the Google API because I thought maybe you could add a simple script to your site (without having to publish anything) - is your client using SharePoint?

Thanks for your reply . Yes they are using SP 2013 . I am also thinking to change the approach from Infopath form to HTML 5 base webform. the reason why i am using infopath form is the frequency of changing , because they use to publish registration form at least 3 weekly for various announcements and workshop registrations with different fields . Regards, sameer

I'd recommend rethinking that design. If they need to have different announcements, etc, on the page, why not have them update that info in an announcements list and a calendar (for example) and then expose those via web parts? I would not like to have to manage anything that involved republishing a form 3 or more times a week! :)

Thanks Hilary for your recommendations . Yes in future forms i am thinking to redesign the architecture . As for current infopath form i did some work around to manage the captcha problem by creating sort of custom captcha ,using share point image library to hold almost hundred images with their security codes and on page load or image refresh button i generate random code , to query respected Image from the library to display on the form . If User enter correct image text , i enabled the submit button & if wrong text i am showing the validation message and also disabling the submit button.
