Hide shipping method when order exceeds certain weight

[MortalWombat]

Hi Rod and that's fine to point out.

The 5kg limit on our express option comes from the satchels -- we offer both regular express parcels, as well as the Australia Post express satchel option. This is mainly due to the massive pricing on express parcels. For example, a 5kg express post satchel will cost $20.85 anywhere in Australia, but express post parcels range from $17.20 all the way to $112.45. Yes, that's the extreme ranges, but options nonetheless, and with prices like that, many of our clients naturally want to save on the postage cost.

As for the 22kg limit -- yes, 20kg is the standard Australia Post weight limit, but with a contract they allow up to 22kg.

I hope you can understand now why we are looking to fix this little problem.

I hope you can understand now why we are looking to fix this little problem.

The fix is quite simple, and Ajeh has actually already given the solution, albeit with incorrect values for your needs (he says very cautiously).

Make sure that you are putting that code in the copy of the Table Rate table shipping module that you do not want to show when the weight is over FIVE Kg, ...

And the change you need to make will be...

// disable only when entire cart is free shipping     if (zen_get_shipping_enabled($this->code)) {       $this->enabled = ((MODULE_SHIPPING_TABLE_STATUS == 'True') ? true : false);     }     
 if (!IS_ADMIN_FLAG) {      
 global $cart;      
 if ($_SESSION['cart']->weight > 5 ) {        
 $this->enabled = false;       
}     }     
 if ($this->enabled) {

Cheers
Rod

Hi Rod and thanks.

I had changed the value of 22 to 5 when Ajeh supplied that code, but it wasn't removing the shipping option.

The reason was because I had this section of code below it:

    // check if manufacturers in cart
     if (IS_ADMIN_FLAG == false) {
        global $cart;
        $chk_manufacturer = $_SESSION['cart']->in_cart_check('manufacturers_id', '54');
$chk_manufacturers_id =  $chk_manufacturer;
        if ($chk_manufacturers_id > 0) {
          $this->enabled = false;
        } else {
          $this->enabled = true;
      }
    }

This is there because I use a courier for a brand of very large items.

Anyway, putting Ajeh's snippet below that, rather than above, fixed it up and the shipping option no longer shows when over the specified weight.

Thanks both of you for your help -- it's all a matter of learning what and where :)

Thanks for the update that this is working and for explaining the changes that you needed ...

[drziegler]

The code Ajeh originally supplied can be modified as follows to disable the shipping method over or under a specified cart total:

if (!IS_ADMIN_FLAG) {
  global $cart;
  if ($_SESSION['cart']->total > 20 ) {
    $this->enabled = false;
  }
}

We use this on our site to disable Standard shipping for carts with totals over $20, which is our break point for offering free standard shipping (otherwise we end up with customers selecting and paying for standard shipping on carts over $20 and then complaining because we advertise free shipping).

[dmagic]

can some one help me with this code ? how can disable the 0$ ?

/*
  USAGE
  By default, the module comes with support for 3 zones.  This can be
  easily changed by editing the line below in the zones constructor
  that defines $this->num_zones.
  Next, you will want to activate the module by going to the Admin screen,
  clicking on Modules, then clicking on Shipping.  A list of all shipping
  modules should appear.  Click on the green dot next to the one labeled
  zones2.php.  A list of settings will appear to the right.  Click on the
  Edit button.
  PLEASE NOTE THAT YOU WILL LOSE YOUR CURRENT SHIPPING RATES AND OTHER
  SETTINGS IF YOU TURN OFF THIS SHIPPING METHOD.  Make sure you keep a
  backup of your shipping settings somewhere at all times.
  If you want an additional handling charge applied to orders that use this
  method, set the Handling Fee field.
  Next, you will need to define which countries are in each zone.  Determining
  this might take some time and effort.  You should group a set of countries
  that has similar shipping charges for the same weight.  For instance, when
  shipping from the US, the countries of Japan, Australia, New Zealand, and
  Singapore have similar shipping rates.  As an example, one of my customers
  is using this set of zones:
    1: USA
    2: Canada
    3: Austria, Belgium, Great Britain, France, Germany, Greenland, Iceland,
       Ireland, Italy, Norway, Holland/Netherlands, Denmark, Poland, Spain,
       Sweden, Switzerland, Finland, Portugal, Israel, Greece
    4: Japan, Australia, New Zealand, Singapore
    5: Taiwan, China, Hong Kong
  When you enter these country lists, enter them into the Zone X Countries
  fields, where "X" is the number of the zone.  They should be entered as
  two character ISO country codes in all capital letters.  They should be
  separated by commas with no spaces or other punctuation. For example:
    1: US
    2: CA
    3: AT,BE,GB,FR,DE,GL,IS,IE,IT,NO,NL,DK,PL,ES,SE,CH,FI,PT,IL,GR
    4: JP,AU,NZ,SG
    5: TW,CN,HK
  Now you need to set up the shipping rate tables for each zone.  Again,
  some time and effort will go into setting the appropriate rates.  You
  will define a set of weight ranges and the shipping price for each
  range.  For instance, you might want an order than weighs more than 0
  and less than or equal to 3 to cost 5.50 to ship to a certain zone.
  This would be defined by this:  3:5.5
  You should combine a bunch of these rates together in a comma delimited
  list and enter them into the "Zone X Shipping Table" fields where "X"
  is the zone number.  For example, this might be used for Zone 1:
    1:3.5,2:3.95,3:5.2,4:6.45,5:7.7,6:10.4,7:11.85, 8:13.3,9:14.75,10:16.2,11:17.65,
    12:19.1,13:20.55,14:22,15:23.45
  The above example includes weights over 0 and up to 15.  Note that
  units are not specified in this explanation since they should be
  specific to your locale.
  CAVEATS
  At this time, it does not deal with weights that are above the highest amount
  defined.  This will probably be the next area to be improved with the
  module.  For now, you could have one last very high range with a very
  high shipping rate to discourage orders of that magnitude.  For
  instance:  999:1000
  If you want to be able to ship to any country in the world, you will
  need to enter every country code into the Country fields. For most
  shops, you will not want to enter every country.  This is often
  because of too much fraud from certain places. If a country is not
  listed, then the module will add a $0.00 shipping charge and will
  indicate that shipping is not available to that destination.
  PLEASE NOTE THAT THE ORDER CAN STILL BE COMPLETED AND PROCESSED!
  It appears that the osC shipping system automatically rounds the
  shipping weight up to the nearest whole unit.  This makes it more
  difficult to design precise shipping tables.  If you want to, you
  can hack the shipping.php file to get rid of the rounding.
  Lastly, there is a limit of 255 characters on each of the Zone
  Shipping Tables and Zone Countries.
