Media Mail restriction mod to new, 3-7-14 usps module, any help?

[Ajeh]

If you do not want to see Media when 1 or more Products from categories_id 65 is in the cart, then change the IF:

//if ($chk_media != $_SESSION['cart']->count_contents()) {
if ($chk_media > 0) {

Perfect! Thank you, it's working now.

Hi Ajeh,

I just found this thread today. This is exactly the problem I am working on. I am creating a 1.5.5e site, which has the USPS module (USPS_2016_0107_K8). My client sells a variety of types (and weights) of items, including books. She would like the media shipping option to only appear when ONLY books are being purchased. Mixed type purchases do not qualify for media mail, according to the USPS website. All my clients books are in one sub-category together, which should make this easier, I would guess. But as I read through this thread, I got confused - perhaps because I am working with newer versions of Zen Cart and the USPS module. I made the recommended edits, but resulted in (apparently) excluding media mail from appearing in ALL situations. First, I put a non-media item in cart. No media shipping option appeared = good. Then, added a book to the same cart. Still no media option = also good. Then, I removed the non-media item from my cart so I had just a book in my cart. Still no media option appeared. Could you, perhaps, take a fresh look at this in the 1.5.5e Zen Cart and latest USPS module files and give me some instructions to accomplish my goal of media mail only appearing when ONLY items from the Books category are in the cart?

Look around line 702 and add:

$show_hiddenCost = '';
// bof: test contents for Media Mail
$skip_media = false;
$chk_media = 0;
$chk_media += $_SESSION['cart']->in_cart_check('master_categories_id','65');
if ($chk_media != $_SESSION['cart']->count_contents()) {
$skip_media = true;
}
// eof: test contents for Media Mail

Then add:

// bof: test contents for Media Mail
          if ($type == 'Media Mail Parcel' && $skip_media) {
            // skip Media Mail
          } else {
          $methods[] = array('id' => $type_rebuilt,
                             'title' => $title . $show_hiddenCost,
                             'cost' => $cost,
                             'insurance' => $usps_insurance_charge,
                            );
}

See if that helps ...

Thank you! Worked like a charm!

Glad that all is working now!

Updated to latest USPS (2022-08-07 K11e_) but having an issue with limiting Media Mail Parcel

I would like to only allow Media Mail Parcel when a product from category 45 is in the cart.
If another product is added that is not from category 35, then don't show Media Mail Parcel

Noticed auto.usps_overrides.php

if (stripos($p1, 'Media Mail') !== false) {
$chk_media = 0;
$chk_media += $_SESSION['cart']->in_cart_check('master_categories_id', '45');
if ($chk_media == $_SESSION['cart']->count_contents()) {
$p2 = true;
}

Not understanding what to do

$p2 = false; (Should I change this to True? )

--------------------------------------------------------

usps.php - Do I still need to add this? I added it to line 565


// bof: test contents for Media Mail
$skip_media = false;
$chk_media = 0;
$chk_media += $_SESSION['cart']->in_cart_check('master_categories_id','45');
if ($chk_media != $_SESSION['cart']->count_contents()) {
$skip_media = true;
}
// eof: test contents for Media Mail

--------------------------------------------------------
And this code? Not sure if the is needed since the auto.usps_overrides.php takes care of it? Add it in the Customization area?

// bof: test contents for Media Mail
if ($type == 'Media Mail Parcel' && $skip_media) {
// skip Media Mail
} else {
$methods[] = array('id' => $type_rebuilt,
'title' => $title . $show_hiddenCost,
'cost' => $cost,
);
}
// eof: test contents for Media Mail

The auto-loaded observer will take care of that; no need to provide additional edits to the usps.php shipping module. You'll change the observer's checking clause to read

            case 'NOTIFY_USPS_UPDATE_OR_DISALLOW_TYPE':
                // -----
                // Disallow "Media Mail" unless all products in the cart have a master_categories_id of '45'.
                //
                if (stripos($p1, 'Media Mail') !== false) {
                    if ($_SESSION['cart']->in_cart_check('master_categories_id', '45') !== $_SESSION['cart']->count_contents()) {
                         $p2 = false;
                    }
                }
                break;

I see what's going on with the override, in general. But I don't know how the services are defined any more.

For example, I've tried this code with the text "Small Flat Rate Box" and "USPS Priority MailTM Small Flat Rate Box" and "USPS Priority MailRM Small Flat Rate Box," and it isn't working with any of those. I recall when the designation changed from TM to RM, but neither of those appears to be correct any more.

                // Disallow Small Flat Rate Box             
                if (stripos($p1, 'Small Flat Rate Box') !== false) {
                   $chk_cart = 0;
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','1'); // golden paste
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','2'); // spicees
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','3'); // accessories
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','5'); // livestock feed   
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','10'); // oils
                   $chk_cart += $_SESSION['cart']->in_cart_check('master_categories_id','11'); // pet products
                   $chk_cart += $_SESSION['cart']->get_quantity('148') > 0; // Soothamide
                   if ($chk_cart == $_SESSION['cart']->count_contents() ) {
                      $p2 = false;
                    } 

I feel like I'm missing something obvious, sigh.
