No data inserted into database. Am I wrongdoing it?

I have a form named:"RegistrationForm.php". when i click the "submit button", there's a data inserted in the database (the prove is, there a new row in the database),
but there's no value from user textfield(ic_no,name,email...) that have been inserted.
It means like there's a row of data inserted but without value..

p/s- however, when i click the submit button, it successfully directed me to the "BookingForm.php" with all the session value...it's just that there's no data inserted into the database.

can someone straighten this up for me? am i doing wrong with the coding with the submit button?
here's the code



<?php

session_start();

$_SESSION['ic_no']=$ic_no;

$_SESSION['name']=$name;

$_SESSION['address']=$address;

$_SESSION['tel_no']=$tel_no;

$_SESSION['email']=$email;

?>

<body>

  <table width="285" border="1">
