Using Hidden Fields to Filter SPAM in Stand-Alone Profiles
November 10, 2011, 07:55:49 pm
Hi All,


Sorry if I'm a bit of newbie when it comes to working with CiviCRM. I'm trying to figure out how to filter out SPAM that we're receiving through a stand-alone profile form that we're using for our newsletter sign-up.

I was interested in Piotr's suggestion here in this thread: http://forum.civicrm.org/index.php?topic=12037.0

Where he suggests using a hidden field as a kind of 'honeypot' to trick SPAM robots. While the technique seems simple enough, I'm not sure if I'm skillful enough as a developer to sort out with CiviCRM's hooks.

I think "hook_civicrm_validate" could be used to check to see if the hidden field has a value and here: http://forum.civicrm.org/index.php?topic=17020.0, it looks like there is an easy way to add hidden-fields to profiles.

However, I don't understand how to find the value for $formName. It was suggested in another thread to put a printstatement in the hook to find the form name, but I'm not quite sure how that works. Any help, advice or examples would be greatly appreciated.

Thanks,

Tak

as mentioned in http://forum.civicrm.org/index.php/topic,17020.0.html

$formName = class name of the form that is used to render the form. So in case of profile it is "CRM_Profile_Form_Edit"

I would recommend reading developer book: http://en.flossmanuals.net/civicrm-developer-guide/

You should also enable recaptcha for your profile to reduce spam.
