Passing a value from php to "form"

[chas2007]

I need to pass a variable from a php function to a form. Does anyone have an example of code that would do this?

Below is the code. I need to pass the "return value" from the php function mem_cost to the "amount" listed in the "form"

 <?php 
function mem_cost()
{
$w_month = strftime("%m");
 
if (($w_month >= "01") && ($w_month <= "06"))
        {
        $amt = "30.00";
        return $amt;
        }
else
        {
        $amt = "60.00";
        return $amt;
        }
}
?>
 
<form target="bridge-data" action="https://www.nowhere.com/display.html" method="post">
<input type="image" src="http://www.nowhere.com/image/btn/btn01.gif" border="0" name="submit" alt="Press here for to purchase item">
