[RESOLVED] Flying around d Web - Post action coding

[FuzMic]

Hi members / gurus

Just got into the learning curve of numerous web coding and is really STRUGGLING. Thank God, my associates here have moved on much earlier and have VB6 also to deal with these matters here. So here i go..

Frequently we have form that starts off with lines such as

<form name="DataFrm1" method="post" action="index.php" onsubmit="Frm1_validation()">

or

<p><iframe style="display: none;" name="hidden_iframe" width="320" height="240"></iframe></p>

<form id="DataFrm2" action="https://webxxx.com/folder/###222###/formResponse" method="post" onsubmit="submitted=true;" target="hidden_iframe">


Questions based on the above 2 snippets:
1 Where do i find the Frm1_validation() in the website folder; i presume this is a function
2 What's the difference between form id & form name
3 Is formResponse a php or html file in the folder?
4 Is the numbers ###222### the encrypt codes for the method post to work?

Pardon me if my questions are over the place. Do teach
