Simple PHP Contact Form + jscript validation + anti-bot

/ Published in: PHP

A simple to use framework for a contact form. This is missing some serious validation and such but is a good startin' point for any simple contact form.

The input field named 'botty' is an input field we hide with css.. if data is sent to the handling file from that field then we know a non-human filled this form out.. and it kills the script.

** just added some simple jscript to handle some mild validation.

CSS
<style type="text/css">  #botty {display:none;} <style>

Javascript
<script type="text/javascript">

function checkform(form){

// check first name
if (form.FirstName.value == "") {
alert( "Please enter your First Name." );
form.FirstName.focus();
return false ;
}

// check last name
if (form.LastName.value == "") {
alert( "Please enter your Last Name." );
form.LastName.focus();
return false ;
}

// check email field
if (form.email.value == "") {
alert( "Please enter your Email Address." );
form.email.focus();
return false ;
}

// check for valid email addy
var apos=form.email.value.indexOf("@");
var dotpos=form.email.value.lastIndexOf(".");

if (apos<1||dotpos-apos<2){
alert("Not A Valid Email Address!");
return false;
}

// ** END **
return true ;

}
</script>
