Answer 1

1. Having two forms that post to different places is the simplest method

2. Name your buttons:

   <input type="submit" name="form_action" value="Login" />
   

   and

   <input type="submit" name="form_action" value="Register" />
   

   When it comes to processing the form, just hookout form_action and it should equal Login or Register.

   This requires some more server-side logic but should work if you need your two forms to be tightly combined.

Answer 2

You can include some Javascript code for this.

<form name="Form1" method="post">

Your Name <input type="text" name="text1" size="10" /><br />

<INPUT type="button" value="ButtonLogin" name=button1 onclick="return OnButtonLogin();">
<INPUT type="button" value="ButtonRegister" name=button2 onclick="return OnButtonRegister();">

</form>

like this:

<script language="Javascript">
<!--
function OnButtonLogin()
{
    document.Form1.action = "Login.do"
    document.Form1.target = "_blank";    
    document.Form1.submit();             
    return true;
}

function OnButtonRegister()
{
    document.Form1.action = "Register.do"
    document.Form1.target = "_blank";    
    document.Form1.submit();             
    return true;
}
-->
</script>
