Add captcha validation to my custom form for Frontend posting

i have implemented the frontend form, which enables UNREGISTERED users to post on my site.

Everything in working perfectly, the only problem I have is with the implementation of the captcha.

All of the captcha solutions I found needs to put some outer file in the form action. But my form has this syntax:

<form action="">

I do not know what to do? If I put the file in the action field, I cannot add the post anymore. How would I put the verification code for the captcha in the same file as the form is? Or any better solution?

Thank you very much!

If you know php well use the Zend Framework. I use it for all of my captcha's. Check out http://framework.zend.com/manual/2.0/en/modules/zend.captcha.operation.html for more information. It is usually used in combination with http://framework.zend.com/manual/2.0/en/modules/zend.form.quick-start.html#zend-form-quick-start so you might want to become familiar with both articles.

Also, I don't know how much traffic you get but if you are a low traffic site there are alternatives to captcha that work pretty well, and don't scare off users by the difficulty of translating the text. For example a user could solve a math problem like what is two plus two. And the bot won't be able to solve that, or you could use a blank hidden field that if the bot fills it out, then the user can't register.

EDIT: Well your best bet then is to use those alternatives. They work for 99.9% of bots and I never have issues when I use them, especially in combination. Add something like 

<input type="hidden" value="" name="blah" />

And then test the form in php with

if (strlen($_POST["blah"]) > 0)
{
     die();
}

And that should keep out most bots. If you need more security add something like.

<p>Add two plus two</p>
<input type="text" name="check" />

and the php

if ($_POST["check"] != 4)
{
    die();
}

That should work for you.
