Flat rate or similar module to only display when over a certain weight?

[sam_m]

Hello,

This is driving me crazy, and im sure its more simple than im finding it. I want to setup a shipping module so say for example the total weight is 2kg or more, It will then kick in with that module (or flat rate), but obviously anything under 2kg wont show the module at all?

I think ive spent too much time with the shipping and for some reason this has got me confused

Any help would be great
thank you
Sam

Or to rephrase it, use weight as a minimum order value instead of price

Thanks
Sam

You would need to customize the Flat Rate flat shipping module by cloning it for your heavier orders ...

Then, you can customize it further to only show when the weight is >= 2 ...

This can be done by controlling the $this->enabled on the shipping modules and when set to false, they do not show, and when set to true, then the do show ...

To illustrate Ajeh's point, I have a clone of zonetables shipping module, and modified the code as follows to govern the display of the module (shipping option) based on the weight:-

  function zonetable() {
    global $order, $db, $total_weight;

    // CUSTOMIZE THIS SETTING FOR THE NUMBER OF ZONES NEEDED
    $this->num_zones = 6;

    $this->code = 'zonetable';
    $this->title = MODULE_SHIPPING_ZONETABLE_TEXT_TITLE;
    $this->description = MODULE_SHIPPING_ZONETABLE_TEXT_DESCRIPTION;
    $this->sort_order = MODULE_SHIPPING_ZONETABLE_SORT_ORDER;
    $this->icon = '';
    $this->tax_class = MODULE_SHIPPING_ZONETABLE_TAX_CLASS;
    $this->tax_basis = MODULE_SHIPPING_ZONETABLE_TAX_BASIS;
    // disable only when entire cart is free shipping
    if (zen_get_shipping_enabled($this->code)) {
      $this->enabled = ((MODULE_SHIPPING_ZONETABLE_STATUS == 'True') ? true : false);
    }
    // Minimum Shipping Weight: If the shipping weight less than 2Kg disable the module
    if ($total_weight < 2) {
      $this->enabled = false;
  	}

(parts I added are in red).

PS: a SECOND clone I made (zonetablestwo) reverses the limiter and shows another module when the weight is MORE THAN 2kg.

Simply reverse:

// Minimum Shipping Weight: If the shipping weight more than 2Kg disable the module
    if ($total_weight > 2) {
      $this->enabled = false;
  	}

Be aware that the $total_weight does not include the Tare Rate ... and you could end up with different results on checkout_shipping ...

WELL SPOTTED LINDA!

Yes... my TARES are set to "null" as my actual product weights factor in the weight value of packaging.

(By the way... is there a way to INCLUDE tare in my code example?)

[Ajeh]

The problem is, it knows the total weight plus the tare in the quote of the shipping module, example:

  function quote($method = '') {
    global $order, $shipping_weight;
echo 'QUOTE: ' . $shipping_weight . '<br>';
