I’m using this script to validate my php form.

```auto

<script>

function validate()

{

	dm = document.contact;

	if(dm.elements["name"].value == "")

	{

		alert ("Please Enter Your Full Name");

		return false;

	}
	
	if(dm.elements["comments"].value == "")

	{

		alert ("Please Enter Your Comments");

		return false;

	}
	
	if(dm.elements["email"].value == "")

	{

		alert ("Please Enter Your Email");

		return false;

	}

	var str = dm.elements["email"].value;

	var reg1 = /(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/; // not valid

	var reg2 = /^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/; // valid

	if (!reg1.test(str) && reg2.test(str)){ // if syntax is valid

	   return 1;//return true;

	}else{

		alert ("Invalid Email entered");

		return false;

	}

}

</script>

```

I would like to add another input for security.

It would be something like:

“Please type the word ‘puppy’ into the space below:  
\_\_\_\_\_\_\_\_\_\_\_\_”

Then the script could check to see if the word “puppy” was typed into the input. If not, it would have a pop up saying “Please type ‘puppy’ into the appropriate space”… or something like that.

I’ve tried searching… but i dont know what that would be called. Any ideas on how I could implement that?

```auto
if(dm.elements["puppyfield"].value != "puppy")

	{

		alert ("You've killed a puppy!");

		return false;

	}

AHHHH!

That’s wonderful, thank you!

But as I was sitting here thinking about this solution, I thought… what if the spammer has javascript disabled? Which I think it most certainly would…

So know I need to figure out how to do this serverside… uhg!

But this is a big help, thanks!
