  Old  How to add calculating captcha

I have a website and getting 1000s of emails from website form. All the forms are just with random content. I have added a javascript to all the fields to make sure all the fields are filled and they are just placing random contents in the fields.

In wordpress website automatic captcha is installed but as this is the html website I have added text captcha with letters which was sending spam leads again and was not able to block the spam emails. Than I tried adding image captcha but got response from clients that its very difficult for them. I am thinking of using numeric captcha like addition or subtraction questions.

Any other way of stopping spam or let me know steps for adding calculation captcha.

  Old  captcha

the best captcha you can add is the calculation captcha which refreshes addition and simple calculation questions.

this captcha as in text even if directly copied from robots will give the error.

You can add them by adding a small php code.

Graphic or image captcha may also work but they are very hard for some users and you may lose the actual clients because of them.

search on google adding numeric captcha to website
