OpenEMM Technical Support Forum

Hello openEMM-users,

I wanted to try a CAPTCHA but couldn't include the input-verification as the form doesnt support PHP because it seems to be a html-file (I can't change it to .php as I have no direct contact with the form-file which contents I change with the backend)

1) Is there a way to use PHP-Code in the sign-forms?
2) How do you protect your sign-up form?

Regards,

That's an interesting question.

I can't see how you could use PHP immediately as it is a server-side language. You'd need to somehow get a PHP interpreter running in, or attached to, the Resin container.

Two alternatives spring to mind.

For server-side find a captcha for Java and integrate that into OpenEMM,

The other way would be to do something using Javascript and run it in the browser...

Thanks for your reply.
I also thought about a Javascript solution. I fear losing alot of potential sign-ups due to a javascript-barrier.
Unfortunatly I got no Java-skills, so I won't be able to implement a server-side solution

But maybe there is another way to reduce spam: Is it possible to rename the standard-records (FIRSTNAME, SURNAME and EMAIL) in the form? Because its really easy for the bots to crawl for openEMM-signups with those standard-fields (I recognized that the bots dont fill in the fields I created). So if I could rename the „EMAIL“-Field to „HONEYPOT“ the spam should be reduced.

Anonye knows how to rename the EMAIL-Field?

Hmmm, not sure.

You will probably have to modify the code somewhere and do a translation from "HONEYPOT" to "EMAIL".

That means you will need Java skills.

The alternative, is you create a form in PHP and deal with that how you wish then send the captured data to OpenEMM using the webservices interface.

PS, I have used Javascript validation for some of the fields (especially email). You can see how I did it here: http://www.openemm.org/forums/ftopic1030.html
