But i am facing problem when i click on submit button after checking all validations,its not submitted.

<input type="button" name="button" value="Submit" onClick="return submit_form();buttonClicked(1);">
<input type="button" name="button" id="button" value="Preview" onClick="buttonClicked(2)">
<input type="button" name="button" id="button" value="Print" onClick="buttonClicked(3)">

<script type="text/javascript">
function buttonClicked(which){
if (which == 1 ) {   
document.f1.action = 'ebooking_email.php';
}
  else if(which==2) { 
      document.f1.target="_blank";
         document.f1.action = 'preview_booking.php'
    }
	 else if(which==3) { 
        document.f1.target="_blank";
         document.f1.action = 'ebooking_print.php'
    }
     document.f1.submit(); 
}
</script>

put alert() calls in each of your if functions to see if any of them get called.

I don't think there's such a thing as document.f1

This is a Javascript issue and not a PHP problem. You have better chances of getting a good quick answer if you posted this in the JavaScript forum.

Try using: document.forms[0].*

hello
f1 is the id of your form?
you can give name attribute to your form and use

document.forms["f1"].submit();
that f1 is value of the name attribute form
