:confused:I am new here.How else should I answer questions?

This is a community forum and I am here help and answer questions. :| Please refrain from posting such comments.:mad:

Here is the complete code without ajax functionality. You didn't mention in the question if you wanted to display result without loading the php page.The login.html could looks like this:

</pre>
<pre lang="Javascript">function validate(){
if((f1.login.value == "") || (f1.password.value == ""))
{
alert("you must enter your name and password");
return false;
}
else
{
return true;
}
}</pre>
<pre lang="HTML">

User Name
Password

The validate.php could look like this:

Add a new student
Remove a student";
}
else
{
// GO BACK link
echo "GO BACK";
// javascript displays message
echo "alert(\"wrongpassword and/or login please try again\");";
}
}
}
?>

Hope it answers your question :)
