Setting Shipping Methods Based on Weight

Hello all,
So I have searched around for this but I have mainly found people wanting to restrict certain carriers based on things such as individual items, weight, cost, etc. What I have not found is where change the usps.php file so that I can do the following scenario (ONLY for International shipments):

When the total weight is <0.99lbs, then show the options:
USPS Priority Mail Int Flat Rate Env
USPS Express Mail Int Flat Rate Env
and NOT show:
USPS Priority Mail International
USPS Express Mail Int

The reason is to reduce the shipping cost to my customers since the items that are the least amount of weight (which you would have to buy a ton of to get to 0.99lbs total weight) are small and can be shipped via an envelope and dont need a box.

Please let me know what php lines are needed to solve this, thanks

You would need to test the shipping method $type in the: function quote

And mask/hide/skip the results when the $usps_shipping_weight is <= 0.99 ...

Ok so I think this is the part of the usps.php file you are saying I should change:

       // BOF: UPS USPS
        $this->quotes = array('id' => $this->code,
        'module' => $this->title . $show_box_weight);
        // EOF: UPS USPS

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]);

          // BOF: UPS USPS
          $title = ((isset($this->types[$type])) ? $this->types[$type] : $type);
          if(in_array('Display transit time', explode(', ', MODULE_SHIPPING_USPS_OPTIONS)))    $title .= $transittime[$type];
          /*
          $methods[] = array('id' => $type,
          'title' => ((isset($this->types[$type])) ? $this->types[$type] : $type),
          'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          */
          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
        } 

So how do I set up the "if else" statement so that one of the types is allowed only when less than 0.99 lbs. I dont see anything about the different types, so is it in whatever the MODULE_SHIPPING_USPS_OPTIONS is referring to?
Sorry this is my first time with PHP, and though related to html I am still in the learning stage.

Add this echo below the list:

          list($type, $cost) = each($uspsQuote[$i]);
echo 'I SEE usps type: ' . $type . '<br>';

Based on the results of the $type you can add an IF condition or a CASE condition to control the building of the:

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);

If nothing is added to the $methods[] based on the $type then it will be excluded from the shipping options ...

Ok so something like this?

// BOF: UPS USPS
        $this->quotes = array('id' => $this->code,
        'module' => $this->title . $show_box_weight);
        // EOF: UPS USPS

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]);

       echo 'I SEE usps type: ' . $type . '<br>';

          // BOF: UPS USPS
          $title = ((isset($this->types[$type])) ? $this->types[$type] : $type);
          if(in_array('Display transit time', explode(', ', MODULE_SHIPPING_USPS_OPTIONS)))    $title .= $transittime[$type];
          /*
          $methods[] = array('id' => $type,
          'title' => ((isset($this->types[$type])) ? $this->types[$type] : $type),
          'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          */

      if($usps_shipping_weight is <= 0.99){

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);

      } else{

      $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
      }

        } 

But how do I specify which type to filter for?

[Ajeh]

Note: on the IF you might use:

      if($usps_shipping_weight <= 0.99){

Look at the output of the echo for the $type when you are looking at shipping costs ...

Which one(s) do you want to turn off when <= .99 ...

[PeauProductions]

Ok here is the echo:

I SEE usps type: Global Express Guaranteed
I SEE usps type: Express Mail International (EMS)
I SEE usps type: Priority Mail International
I SEE usps type: Priority Mail International Flat-Rate Envelope

I only want the last one to show when total weight is less than or equal to 0.99 lbs

[Ajeh]

You will have to adjust this for the other methods but to give you an idea ...

          $show_it = false;
          if ($usps_shipping_weight <= 0.99) {
            // if less than or equal to 0.99 and $type is Priority Flat-Rate show it
            if ($type == 'Priority Mail International Flat-Rate Envelope') {
              $show_it = true;
            }
            if ($type == 'Priority Mail International') {
              $show_it = false;
            }
          } else {
            // if greater than 0.99 show it
            $show_it = true;
          }
          if ($show_it == true) {
            $methods[] = array('id' => $type,
                               'title' => $title,
                               'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          }

There are other ways to do this ... but this is just to give you an idea of what you can try for this ...

NOTE: don't forget to test with National shipping methods at this low weight and setup for those as well ...

Ok it is working, I will post the working code here soon...but more importantly, how do I filter for Domestic and International?
I only want this to happen for International shipping, but it is doing so for both International and Domestic.

[PeauProductions]

Ok scratch that, I figured it out. The domestic mailing is just named with the EXPRESS and PRIORITY names, so there is no more filtering being done besides that. Here is the code that works great, though sure seems longer than it should be. I am basically only filtering the shipping methods so that the Flat Rate Envelopes for Priority and Express are allowed to show up if the package weight is less than or equal to 0.99 lbs.
Place this in the includes/modules/shipping/usps.php

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]);

      // echo 'I SEE usps type: ' . $type . '<br>';

          // BOF: UPS USPS
          $title = ((isset($this->types[$type])) ? $this->types[$type] : $type);
          if(in_array('Display transit time', explode(', ', MODULE_SHIPPING_USPS_OPTIONS)))    $title .= $transittime[$type];
          /*
          $methods[] = array('id' => $type,
          'title' => ((isset($this->types[$type])) ? $this->types[$type] : $type),
          'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          */
          
          $show_it = false;
          if ($usps_shipping_weight <= 0.99) {
            // if less than or equal to 0.99 and $type is Global Express Guaranteed, Express Mail International (EMS) Flat-Rate Envelope, or Priority Flat-Rate show it
            if ($type == 'Global Express Guaranteed') {
              $show_it = true;
            }
            if ($type == 'Express Mail International (EMS) Flat-Rate Envelope') {
              $show_it = true;
            }
            if ($type == 'Priority Mail International Flat-Rate Envelope') {
              $show_it = true;
            }
            if ($type == 'Priority Mail International') {
              $show_it = false;
            }
            if ($type == 'Express Mail International (EMS)') {
              $show_it = false;
            }
            // always show Domestic Shipping
            if ($type == 'EXPRESS') {
              $show_it = true;
            }
            if ($type == 'PRIORITY') {
              $show_it = true;
            }
         } else {
            // if greater than 0.99 show it
            if ($type == 'Global Express Guaranteed') {
              $show_it = true;
            }
            if ($type == 'Express Mail International (EMS) Flat-Rate Envelope') {
              $show_it = false;
            }
            if ($type == 'Priority Mail International Flat-Rate Envelope') {
              $show_it = false;
            }
            if ($type == 'Priority Mail International') {
              $show_it = true;
            }
            if ($type == 'Express Mail International (EMS)') {
              $show_it = true;
            }
            // always show Domestic Shipping
            if ($type == 'EXPRESS') {
              $show_it = true;
            }
            if ($type == 'PRIORITY') {
              $show_it = true;
            }
         }
          if ($show_it == true) {
            $methods[] = array('id' => $type,
                               'title' => $title,
                               'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          }
      } 

Thanks for the help, Im getting a hang of this php thing a little more.
