Waiting for your replies.

Thanks.

 

Not sure if I'm following you but if the "square box" which is green is an HTML element you can use CSS to change the color.

 

use Firefox "Firebug" addon to determining the path to your box element, then change its color property using javascript (not sure why is it in php section)

 

Hi,

<?php

//Select data from database $data  array;  //
.....
if($data['payment_done'] == 'yes'){
	$color = 'red';
}else{
	$color = 'green';
}
......
?>

PHP:

<div style="background-color: <?php echo $color; ?>" id="box"> 
your box 
</div>

Code (markup):

 

The best solution is to provide a membership so PayPal buyers will always see that green box.
