Is there a way to set a minimum order on a paypal button?

For instance, I want to offer a discounted price for anything over 26 pair.

If someone orders less than 26 pair, it would be regular price

If over 26 pair it would input a discounted price.


Any suggestions?

how about using a script (e.g : php or javascript (if the order amount and paypal button on the same page)), create 2 paypal button with 2 different prices.
the script will check how many order then will change/print out the right button

Since I'm a novice coder. Could you explain how I could do this?

<?php

if (!empty ($_POST))
{
 if ($_POST['ordertotal']>="26")
 {
  print "Paypal Button for order more than 26";

  } else
 {
  print "Paypal Button for order less than 26";

 }

}

?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
Total Order : <input type="text" name="ordertotal" />
<br />
<input type="submit" value="Order!" />
</form>
