I have a guest book developed in ASP which submits a persons name, location & message to a database pending for approval before displaying on my website.
However, a lot of the submissions are SPAM!
I've tried to prevent automated submissions using DHTML where they have to tick a box before you can submit the form. However it still allows automated registrations.
So my next battle is to use somthing similar to a password verifier where your retype the same text in another field before you can submit the form. However I can't find no decent scripts.
Could you help me incorporate a similar script into this webpage:
<form ACTION="<%=MM_editAction%>" method="POST" name="form_guestlist">

You can probably find more on hotscripts.comThanks for that mate... Ive looked the the examples and I don't know how that would submit to my database...
It just submits to the same page - if I change it it doesn't verify the input was correct.
At the moment my form does this:
<form ACTION="<%=MM_editAction%>" method="POST" name="form_guestlist">Try this <!-- m --><a class="postlink" href="http://ajax.asp.net/ajaxtoolkit/NoBot/NoBot.aspxcaptcha">http://ajax.asp.net/ajaxtoolkit/NoBot/NoBot.aspxcaptcha</a><!-- m --> or other triggering system. its always nice to uses symetric key using RS4 to encode it and post the text on the image.
