Creative Commons plugin for WordPress follows WordPress Coding Standards and WordPress Documentation Standards. Before pushing your work/contribution, make sure it closely follows these standards otherwise it will not be accepted. We use a PHP_CodeSniffer setup with 'WordPress' sniff to check the code against the standards.

If you are not setup to detect WPCS errors, consider the following steps.

1. Install Composer

   Make sure that you have the current version of PHP installed. Then the first step is to install Composer. Install it Globally by following its documentation for your particular OS.

2. Install PHP_CodeSniffer

   Install PHPCS by running the following command in your terminal:

   composer global require squizlabs/php_codesniffer

3. Confirm Installation

   Check your installation by which phpcs, You should get the path to the phpcs executable. If you don't get anything for which phpcs, you need to add this to your .zshrc or .bash_profile (or your shell’s own profile file) so it will make terminal look in that folder too:

   export PATH="$HOME/.composer/vendor/bin:$PATH"

4. Setup WPCS

   Clone the official WordPress Coding Standards repository in your home folder and ensure you are using its master branch:

   git clone https://github.com/WordPress/WordPress-Coding-Standards.git wpcs

   cd wpcs

   git checkout master

5. Tell PHPCS about this directory

   We need to add the ~/wpcs folder, where we cloned wpcs, to the installed paths of phpcs. Replace the path with the path of your wpcs directory:

   phpcs --config-set installed_paths /Users/your-username/wpcs

6. Check Installation

   Confirm that it is working by running the following command:

   phpcs -i

   The output should be:

   The installed coding standards are PEAR, Zend, PSR2, MySource, Squiz, PSR1,
   PSR12, WordPress-VIP, WordPress, WordPress-Extra, WordPress-Docs and
   WordPress-Core
   

   If it does not include the WordPress Standards, most probably the installed_paths config option is wrong. Make sure that it points to the right directory.

7. Visual Studio Code Workflow

   To configure VSCode so that it may report errors right in the editor, install phpcs extension. Open User Settings and add the following settings:

   "phpcs.executablePath": "/usr/local/bin/phpcs",
   "phpcs.standard": "WordPress"

   Now, phpcs will report errors inside VSCode. If you are using some other editor, consult its documentation. Once there are no reported errors in your fix, you are good to go.

CC plugin for WordPress uses Gutenberg blocks built by create-guten-block tool. If you are interested, you can read its detailed and well-written documentation. If you want to test/make changes to these blocks, follow the following steps.

1. Setup npm

   First off, make sure you have Node version 8+ and npm 5.3 or more. Clone the repository and move to the branch which houses the blocks. In that directory, open your terminal and run:

   npm install

2. Start Development

   After the install is completed run the following command:

   npm start

   This will compile and run the block in development mode. It also watches for any changes and reports back any errors in your code. Now, you can make changes and test them.

3. Build the Blocks

   Once your development is done, make sure to run this:

   npm run build

   It optimizes and builds production code for your block inside dist folder.

1. Start the @wp-env envrionment using the command

   Still in the directory of the project run the following command to start the development enviroment

   wp-env start

2. Check that the development environment is running

   @wp-env requires Docker to run, ensure you have Docker running and open localhost:8888 to go into the dashboard localhost:8888/wp-admin

3. To stop @wp-env

   wp-env stop

A local docker-compose.yml file is included in the ./dev/ directory. It includes an Apache webserver, the latest WordPress installation files, and a mySQL db server utilizing MariaDB. We have also included a copy of wp-cli for ease of developement and testing.

It is modelled after the official example: wordpress - Official Image | Docker Hub.

To run a local development environment for building and testing contributions you can run the following pattern from the root directory of this repository after cloning it.

docker compose [command]

Be sure to substitute [command] for a valid docker compose command, such as the following to build and start containers:

docker compose up

Or to stop containers:

docker compose down

The first time the build process is run via docker compose -f ./dev/docker-compose.yml up, docker will create two directories within your local repository clone:

• ./dev/db where the database and relevant config will be stored
• ./dev/wordpress where the WordPress files will be stored

It will then mount this plugin's root directory into the /wp-content/plugins/ directory of the WordPress installation. Edits made to your local plugin clone will reflect within the build.

You can then navigate to http://localhost:8080/ and proceed with a manual WordPress installation. After the initial installation the WordPress install will persisist between docker sessions.

If you need to reset the WordPress install to a "clean slate" you can simply delete the db and wordpress directories respectively, and then run docker compose up again to initialize a clean install build.

To access wp-cli, you should have:

• Started the docker container
• Completed wordpress setup from dashboard

For example, the following command uses wp-cli to display the version of WordPress installed:

docker compose exec wpcli wp core version

You can also use the container's shell to execute wp-cli commands:

docker compose exec wpcli bash -i
