How do I use two submit buttons, and differentiate between which one was used to submit the form? [duplicate]

Answer 1

Give name and values to those submit buttons like:

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}
