kaiseki/wp-template-renderer

Render WordPress template parts by slug or from a class, with a configurable class-to-slug generator.

Two renderers, both wired through ConfigProvider:

• TemplateRenderer — renders a template part by slug from a configurable base directory under the active theme (default template-parts), capturing its output as a string.
• ClassTemplateRenderer — renders a template part that lives next to a given object’s class file, deriving the slug from the class short name (kebab-cased by default) via a ClassSlugGeneratorInterface.

Installation

composer require kaiseki/wp-template-renderer

Requires PHP 8.2 or newer.

Usage

Register ConfigProvider with your laminas-style config aggregator. It declares the renderer factories and aliases ClassSlugGeneratorInterface to the kebab-case ClassTemplateSlugGenerator, and exposes a template_renderer config key for the defaults:

use Kaiseki\WordPress\TemplateRenderer\ConfigProvider;

return (new ConfigProvider())();
// [
//     'template_renderer' => [
//         'template_renderer'       => ['template_directory' => 'template-parts'],
//         'class_template_renderer' => ['template_name' => 'template'],
//     ],
//     'dependencies' => [ /* aliases + factories */ ],
//     'hook'         => ['provider' => []],
// ]

Rendering a template part by slug

use Kaiseki\WordPress\TemplateRenderer\TemplateRenderer;

/** @var TemplateRenderer $renderer */
$renderer = $container->get(TemplateRenderer::class);

// Renders <stylesheet>/template-parts/card.php and returns its output.
$html = $renderer->render('card', ['title' => 'Hello']);

// With a name variant: <stylesheet>/template-parts/card-featured.php
$html = $renderer->render('card', ['title' => 'Hello'], 'featured');

The base directory is configurable via template_renderer.template_renderer.template_directory.

Rendering a template part from a class

use Kaiseki\WordPress\TemplateRenderer\ClassTemplateRenderer;

/** @var ClassTemplateRenderer $renderer */
$renderer = $container->get(ClassTemplateRenderer::class);

// For an instance of App\Blocks\HeroBlock, looks for hero-block-template.php
// next to HeroBlock's class file and returns its output.
$html = $renderer->render($block, ['heading' => 'Welcome']);

// Override the derived slug and/or the template name suffix:
$html = $renderer->render($block, ['heading' => 'Welcome'], slug: 'hero', templateName: '');

The slug is produced by the ClassSlugGeneratorInterface binding (kebab-cased class short name by default); the template-name suffix defaults to template_renderer.class_template_renderer.template_name.

Both renderers throw a RuntimeException when the resolved template file does not exist.
