How To Run PHP Script With Form Button and Stay on Same Page

I have a button that runs a PHP script that updates prices on my page. Right now the button redirects to the update page (priceupdate.php). I want the button to run this script, but not redirect to it. It'd even greater if the button's name could change from "Update Prices" to "Prices Updated" after it's been clicked.

I'm aware I'll need to use some javascript, but after some heavy googling I haven't found quite what I'm looking for. Here is what I have so far.

<form action="updateprices.php" method="post">
  <input value="Update Prices" type="submit">
</form>

Open in new window

Any suggestions? I don't have any text to submit, which is the majority of what I've been finding sample scripts for.

Here's the code for a simple price update page.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

</head>
<body>


<?php

$check = '';
$price = '$4.99';

if (isset($_POST['check'])) {
	$check = $_POST['check'];	
}

if (isset($_POST['price'])) {
	$price = '$' . $_POST['price'];
}

if ($check != '1') {

?>
<h1>Price is currently set to: <?php print $price;?></h1>	
<form action='<?php $_SESSION['PHP_SELF'];?>' method="POST">
<table>
<tr>
	<td>Price: <input type="text" name='price' id='price' /></td>
</tr>
<tr>
	<td><input type="hidden" name='check' id='check' value='1' /></td>
</tr>
<tr>
	<td><input type="submit" name='submit' id='submit' value='Update Price' /></td>
</tr>
</table>

</form>
<?php 
} else if ($check == '1') {

?>

<h1>Price has been updated to: <?php print $price;?></h1>	
<form action='<?php $_SESSION['PHP_SELF'];?>' method="POST">

	<td>Price: <input type="text" name='price' id='price' /></td>
