USPS Flat Rate not an option

[CodingLama]

The variable $usps_shipping_weight is not defined at that point ...

Add above your IF statement:

global $shipping_weight;

Then, change all of the $usps_shipping_weight to $shipping_weight ... see if that works better for you ...

Instead of bringing in the global variable, you could use:

$this->pounds

in your conditionals instead.

I want to enable USPS Priority Flat Rate Shipping for some items (Domestic only for now).
I went to /includes/modules/shipping/usps.php. It is 15 pages!

!. What line do I put it in?
2. Is this the correct php language?

global $shipping_weight;
//PRIORITY MAIL OPTIONS
if ($key == 'PRIORITY'){
$this->container = ''; // Blank, Flate Rate Envelope, or Flat Rate Box // Sm Flat Rate Box, Md Flat Rate Box and Lg Flat Rate Box

}
//PRIORITY MAIL OPTIONS
if ($key == 'PRIORITY')
{
if ($usps_shipping_weight < 5)
{
$this->container = 'Sm Flat Rate Box';
}
else if ($usps_shipping_weight < 10)
{
$this->container = 'Md Flat Rate Box';
}
else
{
$this->container = 'Lg Flat Rate Box';
}
}
