2018-07-01 Sunday: how to duplicate handling fee module in Opencart
Contents
Overview
Want to add a fee similar to Opencart's default handling fee for ship-able orders. Free but technical way to do this is to duplicate files which implement the handling fee, making changes in them so they appear as a new Opencart module in Opencart's Extensions -> Order Totals admin page.
Example Of Additional Flat Rate Shipping Modules
$ find . -name '*flat*' ./admin/view/template/extension/shipping/flat_rate_to_europe.tpl ./admin/view/template/extension/shipping/flat.tpl ./admin/view/template/extension/shipping/flat_rate_to_canada.tpl ./admin/language/en-gb/extension/shipping/flat_rate_to_europe.php ./admin/language/en-gb/extension/shipping/flat_rate_to_canada.php ./admin/language/en-gb/extension/shipping/flat.php ./admin/controller/extension/shipping/flat_rate_to_europe.php ./admin/controller/extension/shipping/flat_rate_to_canada.php ./admin/controller/extension/shipping/flat.php ./catalog/model/extension/shipping/flat_rate_to_europe.php ./catalog/model/extension/shipping/flat_rate_to_canada.php ./catalog/model/extension/shipping/flat.php ./catalog/language/en-gb/extension/shipping/flat_rate_to_europe.php ./catalog/language/en-gb/extension/shipping/flat_rate_to_canada.php ./catalog/language/en-gb/extension/shipping/flat.php $
In the path of the third group of files, path admin/controller/extension/shipping one must change a PHP class name near the top of the duplicated file, in a manner similar to:
<?php
// class ControllerExtensionShippingFlat extends Controller {
class ControllerExtensionShippingAndPhytoEurope extends Controller {
Locating Existing OC Module Files
Searching for handling fee related files in Opencart 2.3.0.2 root directory:
$ find . -name '*hand*' ./admin/view/template/extension/total/handling.tpl ./admin/language/en-gb/extension/total/handling.php ./admin/controller/extension/total/handling.php ./catalog/model/extension/total/handling.php ./catalog/language/en-gb/extension/total/handling.php $
Adding a comment block top of newly duplicated and modified files:
// <!-- // 2018-07-01 - file duplicated from ./handling.tpl and modified by Ted, // to support phytosanitation fee. Duplicating Opencart modules in this manner // explained at https://forum.opencart.com/viewtopic.php?t=6696 // // Replacing 'Handling' and 'handling' with '[Pp]hytosanitation' . . . // -->
Creating New Combined Shipping Plus Phyto Rates
Argh, taxes apply per geographic area, but also per product and so are multiplied by number of products in cart! 'Order Total' type fee like handling fee applies to all orders. We need a fee which applies once to the order, per geography . . .
<! -- 2018-07-01 - This OC template file duplicated from ./flat.tpl by Ted, search and replace performed in vim as follows: :.,$s/flat/shipping_and_phyto_europe/g See https://forum.opencart.com/viewtopic.php?t=6696 for OC module duplicating details. -->
