html php post

I have  a variable called total price tat i need to send to the other page, how can i , on the click of a button and using post send this value and change to the new page? something like this...?

 

<form action = "postage.php" method = "POST">

<center><input type = "submit" value = "procceed to checkout" name= "grandT"></center>

<form>

Use a hidden field:

 

<form action = "postage.php" method = "POST">
<input name="total_price" type="hidden" value="<?php echo $total_price; ?>" />
    <center>
    	<input type = "submit" value = "procceed to checkout" name= "grandT">
    </center>
<form>

 

But bear in mind that you will have to check to see if $_POST['total_price'] is the correct price (on postage.php) as users could tamper with the form values before submitting it.
