Thank you,
but regarding the point of : Hidden input element, isn’t it easy for a bot, to check if the input tags were hidden or not, to fill them only if their style don’t hide them!

Anyway, i have read about a very good idea and used it also, which is to create a hidden field, on page load, using javascript, and filling it with an auto randomly generated string, which is written to a cookie at the same time, and on submission, we can check the values, in addition to the differences of dates (between cookie creation and form submission), this way, we don’t punish users, and control the form in a good way.

I’ve tried that many times but the php form always crashes. I’m doing something wrong but I don’t understand php enough to know what.

@Stephanie

PHP code doesnt change. It will be the same as accepting data for any other field $_POST['hidden_field'] and just check if this data is still present.

Wow that hidden input field trick is really good. And logical. I never really considered that option. Thanks for the info

Thanks, You are probably right!

Simple checks should be sufficient for a NOT highly targeted site. Which is 99.999% of the websites in the world!
