The HTML side will be the same. As you're probably aware the only thing that will be different is the scripting behind it.

<?php
//get form variables
$name=$_POST['name'];
//validate
if ($_POST['subsend']) {
  if ($name!='') {
    //name passed verification
  } else {
    echo 'Name must be specified';
  }
}
<html>
<head>
  <title>Test</title>
</head>
<body
  <form action="" method="post">
    Name: <input type="text" name="name" /><br />
    <input type="submit" value="Send Details" name="subsend" />
  </form>
</body>
</html>

That's the very basics.

Depending on what type of inbox box you're using on your form (and what data it contains) depends really on how you validate the data - and how strict you want to be with it.

For example, validating something like a name is easy - either it has content or it doesn't. This can be checked using empty()

if (empty($name)) {echo 'We are empty!';}

For dates you can very specific or relaxed. Does it matter what order the d/m/y are in or can they use whatever format they want?

thanks for the reply.

Just to make it a bit clear.

I have got a textbox for name and another one for email address and a select button (value is cat, cow, dog) from where I will select one and validate the user name and email address.

so the name field should not contain any digit and the email address should be a valid email address...

thanks once again
