A component is a reusable piece of code that can be used in multiple pages. Components are classes that can be used in template files to encapsulate logic and make your code more readable and maintainable.
The ↱ Darken\Attributes\RouteParam attribute allows you to bind route parameters directly to properties in your component class. This makes it easy to access dynamic values from the URL.
The ↱ Darken\Attributes\Inject attribute lets you inject dependencies (like services or database connections) directly into your component properties, making your code cleaner and more testable.
Use ↱ Darken\Attributes\ConstructorParam to pass parameters to your component's constructor, allowing for more flexible and configurable components.
The ↱ Darken\Attributes\QueryParam attribute binds query string parameters from the URL to your component properties.
The ↱ Darken\Attributes\PostParam attribute binds POST request data to your component properties, making form handling straightforward.
Components can have slots—placeholders in the component that can be filled with content. Slots are defined in the component class and can be filled in the template file.
<?php
use Darken\Attributes\Slot;
$component = new class {
#[Slot]
public string $content;
};
?>
<div style="background-color: red;">
<?= $component->content; ?>
</div>
The Compiler will generate openContent() and closeContent() methods on the polyfill class. The openContent() method opens the slot, and the closeContent() method closes it, so everything in between is passed to the $content property.
<h1>Hello</h1>
<?php $component = (new Component)->openContent(); ?>
<p>The slot $content rendered in red</p>
<?= $component->closeContent(); ?>
