Further Information

Supported Bootstrap versions

This plugin supports Bootstrap v4 and v5.

The version can be selected in the plugin settings (Settings > Bootstrap Blocks) or by defining the WP_BOOTSTRAP_BLOCKS_BOOTSTRAP_VERSION constant in the wp-config.php file:

Possible values right now are '4' or '5'. By default Bootstrap version 5 is selected.

CSS Grid

The CSS grid (supported with Bootstrap >= 5.1.0) can be enabled in the plugin settings (Settings > Bootstrap Blocks) or by defining the WP_BOOTSTRAP_BLOCKS_ENABLE_CSS_GRID constant in the wp-config.php file:

eg. define( 'WP_BOOTSTRAP_BLOCKS_ENABLE_CSS_GRID', true );

When the CSS grid is enabled the row and the column blocks will use custom templates for the rendering process:

The support is still experimental since it's also marked as experimental in the Bootstarp library. Please read the official Bootstrap documentation to get more information on how to use it.

Bootstrap library

Please be aware that this plugin does not include the Bootstrap library in your website. You need to do this by yourself. We decided not to include the library so that you can modify Bootstrap to your own needs before loading it.

The easiest way to do this is to add the following to your theme's functions.php:

function mytheme_load_bootstrap() {
    if ( is_admin() ) {
        return;
    }

    wp_enqueue_style( 'bootstrap', 'https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css', array(), '4.3.1' );
    wp_deregister_script( 'jquery' ); // Remove WP jQuery version
    wp_enqueue_script( 'jquery', 'https://code.jquery.com/jquery-3.3.1.slim.min.js', array(), '3.3.1', true );
    wp_enqueue_script( 'popper.js', 'https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js', array(), '1.14.7', true );
    wp_enqueue_script( 'bootstrap', 'https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js', array(), '4.3.1', true );
}
add_action( 'wp_enqueue_scripts', 'mytheme_load_bootstrap' );

Templates

All blocks are implemented as dynamic blocks. This makes it possible to overwrite the template of a block in your theme.

To overwrite a block template create a folder called wp-bootstrap-blocks/ in your theme directory. You can copy the original template from wp-bootstrap-blocks/src/templates/<blockname>.php as a starting point and adjust it to your needs.

Parameters

Developer information

Requirements

Installation

  1. Clone this repository

  2. Install composer dependencies

    curl -s https://getcomposer.org/installer | php
php composer.phar install

  3. Install Node dependencies

    npm install

Compile assets

The build process is based on the official @wordpress/scripts package.

Generate translation files

  1. To extract the labels and generate the languages/wp-bootstrap-blocks.pot file run the following command:

    ./scripts/translations/extract-messages.sh

  2. To update the translation files (*.po) run the following command:

    ./scripts/translations/update-translation-files.sh

  3. To generate the *.mo and *.json translation files run the following command:

    ./scripts/translations/compile-translation-files.sh

Setup local dev environment

The following commands can be used to set up a local dev environment. See the official documentation of @wordpress/env for a complete list of commands.

Testing

There are two types of tests for this plugin:

PHPUnitTests

The PHPUnit tests are stored in the phpunit/ directory. They use fixtures to validate the block output. Each block variant which should be tested needs a manually created file called blockname__variant.html. This file contains the block presentation in the editor (a.k.a. the HTML comment presentation) and needs to be stored in the following folder:

phpunit/blockname/fixtures/blockname_variant.html

The second fixture of each variant is the blockname_variant.output.html file. This file gets automatically generated if the test runs for the first time and the environment variable WP_BOOTSTRAP_BLOCKS_RECORD in the phpunit.xml.dist file is set to true.

To run the tests use the following command:

npm run test:unit:php

or the following command to run a specific test:

npm run test:unit:php -- --filter 'my_test'

Playwright E2E Tests

The Playwright E2E Tests are stored in the playwright directory.

To run the tests use the following command:

npm run test:e2e
