Form Validation Code

[MitchEvans]

Hi all,

I've seen many form validation codes, where users have to enter a unique code in order to validate the form.
I've seen this code on sites where you can use their code but you can't view the code, so you have to link to that site as you've used their code.
Does anyone have any simple code that does this. I just need one text box and a unique code next to it so the form can be validated.

Thanks.

Hope you van help!

CAPTCHA is what you are looking for, "Completely Automated Public Turing test to tell Computers and Humans Apart".

There are a couple out there for free, one has an audio clip you enter what the audio says, here's the link ( PHP library and other enviornments):

Be aware that some 'OCR' readers (used by auto-form fillers) can read some CAPTCHA images.

What I've done on my Forum Registration Page is added a field that MUST be input with a value (which I display in another post on the forum). Then validate that the form value matches the expected result in order to be submitted.

I haven't had a 'bot registration' since I installed it almost a month ago....

So sometimes simple is best. I bet you can even get away with putting something like this on your form:

<B>Validate (input 'hello' here) : </b>
<input type='text' name='validate' id='validate />

Then validate that $_POST['validate'] == 'hello' in your form validation and it will help your cause.

NOTE: My Forum registration form did have CAPTCHA before I added the new field and it still was not stopping the bots !!
