coding help!

Hi All,
i'm new to php, i have small problem to construct my website.
i have a code of "page1.php" which is a form to be filled and submited or have a preview before submit or ... , so i have 4 buttons when i click any one of them will post to "page2.php" and execute only the corresponding code of the last action:

"page1.php"
<?php
<form action="page2.php" method="post">
...
.. code of the form.
.
<input type="submit" name="submit_button" value="submit">
<input type="submit" name="save_button" value="save & continue">
<input type="submit" name="preview_button" value="preview">
<input type="submit" name="clear_button" value="clear">
</form>
?>

"page2.php"
<?php
if(submit_button hit)
{ ... code for submit button...}
if(save_button hit)
{ .... code for save button ...}
if(preview_button hit)
{ ... code for the preview button...}
...
..
.
?>

My question: is there any php function to specify the 'submit_button hit' or 'save_button hit' or any clicked button action? or there any other idea to do the same task?

Note: i did my code like that because i "in my knowledge" can not have a multi form action
<form action="$var" method="post">

Thanx in advance.
Fat.

On page2.php, run something like this:

if($HTTP_POST_VARS["submit_button"] == "submit") {
// do submit code
}
if($HTTP_POST_VARS["save_button"] == "save & continue") {
// do save and continue code
}
if($HTTP_POST_VARS["preview_button"] == "preview") {
// do preview code
}
if($HTTP_POST_VARS["clear_button"] == "clear") {
// do clear code
}

Alternatively, you could give ALL the buttons the same name (say, "button", for example), and use a more elegant solution:

switch($HTTP_POST_VARS["button"]) {
case "submit":
//do submit code
break;
case "preview":
// do preview code
break;
case "save & continue":
// do save and continue code
break;
case "clear":
// do clear code
break;
default:
// user went to page2.php without submitting the form.
// yep, this happens...
}

Have fun...

Thanx a lot for your help, it does work perfect with a switch() statement.
