I always set a hidden field

<input name="action" type="hidden" id="action" value="submit">

Then check if it has been set:

if(isset($_POST['action'])){
## Do whatever
}

Or check specifically:
if($_POST['action'] == 'submit'){
## Do whatever
}

Just to look at the variables for debugging I use:

print_r($_POST);

To use them I use foreach:

foreach($_POST as $key=>$value){
## Examine $key or $value
}
Hope this helps.
