Blocking spam

[9999]

My question is similiar to this post:

Hi all,

 

I need help with my php forms. I read an article that you can prevent form spam by using a hidden field, and requiring it to be blank for the form to be processed. I have no problems with setting the required html / css up, but have no idea where to start with the php code required to stop the form from being sent if left blank. I have very limited knowledge of php, please bare this in mind.

 

Anyone point me in the right direction or explain the code to me please?

 

I've tried a search on the forum but couldn't find anything, and sites that have mentioned the method never explain what you need to do with the php!

 

Thanks in advance...!

 

I placed this in the form:

<input id="human" type="text" />

 

I used this in the CSS to hide the field, this works:

#human {
visibility:hidden;
display:none;
}

 

My question is, what is the correct php code?  I tried this and it didn't work:

If (isset($_POST['human'])) {
     die;
}

 

I also tried this but it kills everything right of the bat without even displaying the form

If (!isset($_POST['human'])) {
     die;
}

First read up on how PHP Forms work. Lots of tutorials around.

 

It will look something like:

If ($_POST['submit_button_name']) {
     If($_POST['human'] == "")
             //process form
     Else
            //spam die();
}
