Where you use $_SESSION[blah]=$_POST you should place that in an if statement like the following.

if (isset($_POST) && !empty($_POST)) {
$_SESSION['blah']=$_POST['blah'];
$_SESSION['asdf']=$_POST['asdf'];
}

This way if $_POST is empty, session will not be assigned an empty value.

You can replace the code in the first few lines of every page withing <?php...?> with the following set of codes

one.php

<?php
session_start();

if (!isset($_SESSION['phone']) && isset($_POST['txt_phone'])) {
	$_SESSION['phone'] = $_POST['txt_phone'];
}

?>

two.php

<?php
session_start();
if (!isset($_SESSION['name']) && isset($_POST['txt_name'])) {
	$_SESSION['name'] = $_POST['txt_name'];
}
if (!isset($_SESSION['email']) && isset($_POST['txt_email'])) {
	$_SESSION['email'] = $_POST['txt_email'];
}

?>

three.php

<?php
session_start();

if (!isset($_SESSION['phone']) && isset($_POST['txt_phone'])) {
	$_SESSION['phone'] = $_POST['txt_phone'];
}
if (!isset($_SESSION['com']) && isset($_POST['txt_com'])) {
	$_SESSION['com'] = $_POST['txt_com'];
}

?>

four.php

<?php
session_start();
if (!isset($_SESSION['email']) && isset($_POST['txt_email'])) {
	$_SESSION['email'] = $_POST['txt_email'];
}

?>

Hope this thing helps.

Hi bhanuprakash,

Your code works, but if lets say that I go from
One ----- > two ---- > threee... the text all remain there..
and when i go back to page one <---- and edit the name, that i change the name...then i go to page 2(two) and come back<--- to page one, the new text name that i have entered is not shown,
It takes the old text thats been typed b4...
How can it be solved..?
:(

I changed it to..

if (!isset($_SESSION['phone']) || isset($_POST['txt_phone'])) {
	$_SESSION['phone'] = $_POST['txt_phone'];

With that if condition you minus well remove the if condition as it will allways pass.
