This is my first attempt at an extension for Opencart and is really just a modification of the existing ups shipping extension. It allows for shipments over 150lbs and uses product sizes to determine box sizes. It does not use a packing algorithm, but uses a more simplistic volume calculation. It's not ideal, but is much better than having no size associated with shipments.
Features:
- Minimum and maximum shipping weights.
- Minimum and maximum volume (box size).
- Minimum shipping rate.
- Negotiated rate support.
- Weight and volume adjustments to account for shipping box and packaging (fixed and percentage).
- Rate adjustment (fixed and percentage).
To Install: There are no modifications to existing files. Just copy the files in and setup the shipping method.
Notes:
- Only the gross shipping weight is displayed, not the UPS dimensional weight since the dimensional weight can vary by shipping method.
- The box size calculation is very simplistic. It calculates the total volume then assumes an approximately square box. However, it will not make any dimension of the box shorter than longest corresponding item dimension. So when combining a 6x10x2 item with a 8x8x3 item, it will generate a box with minimum dimensions of 8x10x3, but it will also increase the box size so that the total volume is greater than the individual items. In this case the minimum volume is 120+192 = 312 so it would generate a 8x10x4 box. Not as good as a packing algorithm, but simpler and not too far off in many cases. You can always allow for some variance with the weight and volume adjustments. A 5% adjustment in this case would result in the perfect 8x10x5 box.
- To see the calculated box sizes turn on the debug mode.
