WordPress Toolkit

Work with common WordPress Plugin and Theme APIs in a
modern, object-oriented way.

By Max Melzer
The WordPress Toolkit is a Composer
module that offers easy access to common WordPress functionality,
inspired by modern PHP frameworks like Symfony.
It’s aim is to provide consistent, object-oriented methods
for WordPress plugin and theme development.

Installation

To use the toolkit, add it to your theme or plugin via
Composer.

cd wp-content/themes/your-awesome-theme
composer init
composer require moehrenzahn/wp-toolkit

Then, you can initialize the Client class in your PHP script. This is
the entry point to all functionality of the toolkit.

<?php
$client = new MoehrenzahnToolkitApiClient();

Requirements

Composer
PHP >= 7.1
WordPress >= 5.0 (older versions may work but are untested)

Features

convenient API around WordPress action and filter management
object manager with simple, automatic dependency injection
template rendering with Model-View-Controller architecture
add and manage

- virtual user accounts
- Transients
- Post Types
- Post Terms and Meta
- Post Meta boxes
- Post filters
- comment Meta
- comment Meta boxes
- settings pages
- admin pages
- admin notices
- AJAX actions
- POST actions

Usage example

Add a CSS file to your theme:

<?php
// Entry point for all actions is the Client object
$client = new MoehrenzahnToolkitApiClient();
$stylesheets = $client->getStylesheetManager();
$stylesheets->add('eule-stylesheet', 'src/css/style.css', '1.0.0');

Add a shortcode with a custom template:

<?php
$client = new MoehrenzahnToolkitApiClient();
$shortcodes = $client->getShortcodeManager();
$shortcodes->add(
    'my-shortcode',
    $client->getViewFactory()->create('shortcode-template.phtml')
);

Create a custom settings page with pre-built input type templates.

<?php
$client = new MoehrenzahnToolkitApiClient();
$client->getAdminPageManager()->addSettingsPage(
    'Sample settings page',
    'sample-settings-page',
    getSections($client)
);

/**
 * @param MoehrenzahnToolkitApiClient $client
 * @return MoehrenzahnToolkitViewSettingsSection[]
 */
function getSections(MoehrenzahnToolkitApiClient $client): array
{
    $sectionBuilder = $client->getSettingsSectionBuilder();
    $sectionBuilder->addSetting(
        'my-sample-setting',
        'A sample setting title',
        MoehrenzahnToolkitAdminPageSettingsSectionBuilder::SETTING_TYPE_BOOLEAN,
        'A sample setting description.'
    );

    $sectionBuilder->addSetting(
        'my-sample-select',
        'Select your thing',
        MoehrenzahnToolkitAdminPageSettingsSectionBuilder::SETTING_TYPE_SELECT,
        'You can also do select inputs!',
       [
           'sample-option-value' => 'Sample option label',
           'another-option-value' => 'Another option!',
       ]
    );
    
    return [$sectionBuilder->create('sample-section', 'A sample settings section')];
}

Use the built-in View class to render your templates and get
access to features like lazy-loading images and partials:

<?php /** @var MoehrenzahnToolkitView $view */ ?>
<h2>Here comes a lazy-loaded partial that is only loaded when it's scrolled into view:</h2>
<?php $view->renderLazyPartial(
    'your-template-to-load.phtml',
    'your-static-placeholder-template.phtml'
) ?>

Use the object manager to initalize objects with automatic dependency resolution.

<?php 
$client = new MoehrenzahnToolkitApiClient();
$objectManager = $client->getObjectManager();
/**
 * The object manager will try to automatically and recursively
 * resolve all dependencies of the given class.
 * Don't use this for very large projects since it can impact performance.
 */
$customObject = $objectManager->getSingleton(YourCustomClass::class);
