Pakettikauppa WordPress plugin for WooCommerce

Maturity

This software is now available for General Availability.

Installation

This plugin can be installed via WordPress.org plugin directory, WP-CLI or Composer:

wp plugin install --activate woo-pakettikauppa
# OR
wp plugin install --activate https://github.com/Seravo/woo-pakettikauppa/archive/master.zip
# OR
composer require seravo/woo-pakettikauppa

The plugin requires WooCommerce >=4.4 to be installed, with shipping zones configured and this plugin activated and settings set.

Naturally the store owner also needs to have a merchant account at Pakettikauppa.

Note! If you already have shipping contracts with Posti, Matkahuolto or DB Schenker with reduced prices, you can contact the customer support of Pakettikauppa to get those contracts via Pakettikauppa so you can use the WooCommerce Pakettikauppa plugin with your current shipping contracts.

Important! Before you start using this plugin, please check with your hosting provider that you have directory listing disabled. For more information about directory listing, check the documentation for Apache or Nginx.

Developer docs

Please note that the official docs at https://docs.woocommerce.com/document/shipping-method-api/ contain partially outdated information. For more information, see wiki at https://github.com/woocommerce/woocommerce/wiki/Shipping-Method-API or dive directly into the source using GitHub search to find up-to-date examples on how to extend the shipping method class.

Running a local development environment

To develop woo-pakettikauppa (or any WordPress plugin) you need to have a running WordPress installation. If you want to use Seravo/WordPress as a local development environment clone it to your computer and fire it up in Vagrant or Docker following its instructions. Once done, you will have a clean and pretty empty WordPress site.

Assuming you have the local development environment running in directory wordpress and this plugin is checked out next to it, you can use entr and rsync to automatically sync the woo-pakettikauppa contents into the local development environment:

find * | entr rsync -vr . ../wordpress/htdocs/wp-content/plugins/woo-pakettikauppa | ts

This is handy, as no matter what happens to the local development environment the git checkout of woo-pakettikauppa is always protected from harm and you can have your text editor and git tools running in that directory always in the same way.

Running tests in local development environment

There are preconfigured phpcs.xml and phpunit.xml files in the project, so running tests is very easy:

vagrant$ cd /data/wordpress/htdocs/wp-content/plugins/woo-pakettikauppa/
vagrant$ phpcs
vagrant$ phpunit --verbose

Note that the phpcs and phpunit versions in the local development version might differ from the versions used in the CI system and thus produce different results.

Travis CI and automatic testing

This project has a .travis-ci.yml definition which can be used by anybody. Just follow these steps:

Create an account at Travis-CI.org by logging in with your Github.com account.
Make sure you have a fork of this repository in your own Github.com account.
Open the Travis-CI.org settings page and click "Sync repositories"
Search for woo-pakettikauppa in your repository list and enable automatic testing for the repository it.
Initially the page https://travis-ci.org/<username>/woo-pakettikauppa will be empty, but as soon as you push your first commit Travis-CI will run the first built. You can also manually trigger a build to get it started.

Debugging failed Travis CI jobs

First read carefully all the output of the failed jobs. Most of the time the reason to the failure is clearly stated.

You can also simulate the tests Travis CI runs by running inside the local development environment the same commands that .travis.yml runs:

vagrant$ cd /data/wordpress/htdocs/wp-content/plugins/woo-pakettikauppa/
vagrant$ SNIFF=1 ./tests/install-tests.sh
vagrant$ SNIFF=1 ./tests/run-tests.sh

To control what tests are run by setting variables like 'SNIFF' and others. See .travis.yml for all options used in current matrix.

Travis CI has published travis-build for converting the .travis.yml file into a .sh script you can run if you feel adventurous. They also offer a debug build mode that can be used to debug failed builds via SSH directly on Travis' servers.

Translating

If you add new translatable strings or edit existing once, you have to regenerate woo-pakettikauppa.pot under core/languages. Easiest way to do it is use wp-cli:

wp i18n make-pot . core/languages/woo-pakettikauppa.pot

Branching and releases

Development always targets master branch

All bugfixes and new features are developed on separate git branches. Work-in-progress can be marked by appending "WIP:" to the commit message or the pull request title. Once a feature is ready, a pull request is opened for comments and review. Pull requests should not include any updates to the changelog or version number, as those are done separately at release time to match the actual release. Making a pull request implies that comments and review are requested, so wait at least 24h after making a new PR so others have time to respond.

Very small bugfixes that don't need any reviews (e.g. fixing spelling errors) can be applied directly on master. Note that all commits must pass CI, so Travis-CI needs to see a commit on some branch first and Github needs to register that commit as passing CI. Then those commits can be merged directly on master by a developer who has write access to master, without making a separate pull request on Github.

As this is a WordPress plugin, there can only be one version released. Thus there are no separate maintenance release branches (once 2.1.x has been released, the next release must be 2.1.y or higher, there cannot be any maintenance releases for 2.0.x).

Making a new release

All improvements on land on master, and when the current master is tested and deemed fit for a release, the release itself include:

Make a temporary branch where you bump the version number and update the changelog, ensure CI passes
Send an email to asiakaspalvelu@pakettikauppa.fi as a heads-up about the upcoming release
Wait for 1-2 work days
Merge the temporary branch on master and tag it using git (don't use Github's release features, it can mess up the git tag references)
This repository hooks into https://deployer.seravo.com/, Packagist and all release actions happen automatically based on the git tag

Architecture

The plugin is written so that it can be easily forked to a whitelabel version, containing only a subset of shipping providers and a custom branding. This is achieved by using an abstract class as a factory for the plugin component. Each component can be replaced by simply overloading a method.

The Woo_Pakettikauppa_Core\Core class is responsible for loading all components, and it serves as a bridge between the components. The instance is passed to most subclasses of the plugin, such as Woo_Pakettikauppa_Core\Admin, which keep a reference to it under $this->core.

The subclasses are responsible for doing the actual heavy lifting. Admin handles operations in wp-admin, Frontend handles frontend, Shipment is used for creating shipment labels, etc.

Text is bit of a special case, it's only real purpose is to serve as a key-value store for strings that require translation. Currently the plugin has __ and _e calls scattered all over it – in the future, all of them should live in Text. The advantage of doing so is being able to replace any text in the whitelabel forks.

Templates

The plugin have some template files, which is displaying via wc_get_template function, so they can be overrided in the theme. To do that, need copy files from Pakettikauppa plugin directory (/wp-content/plugins/woo-pakettikauppa/templates/pakettikauppa) to Wordpress theme directory (/wp-content/themes/<theme_name>/woocommerce/pakettikauppa).
