This library provides templates rendering abstraction supporting layout-view-subview hierarchy, custom renderers with
PHP-based as default, and more. It's used in [Yii Framework](https://www.yiiframework.com/) but is usable separately.
## Requirements
- PHP 8.1 or higher.
## Installation
The package could be installed with [Composer](https://getcomposer.org):
```shell
composer require yiisoft/view
```
## General usage
The package provides two use cases for managing view templates:
- [Basic functionality](docs/guide/en/basic-functionality.md) for use in any environment.
- Advanced functionality for [use in a web environment](docs/guide/en/use-in-web-environment.md).
### State of `View` and `WebView` services
While being immutable and, by itself, stateless, both `View` and `WebView` services have sets of stateful and mutable
data.
`View` service:
- parameters,
- blocks,
- theme,
- locale.
`WebView` service:
- parameters,
- blocks,
- theme,
- locale,
- title,
- meta and link tags,
- JS/CSS strings,
- JS/CSS files.
The state of `View` and `WebView` isn't cloned when the services are cloned. So when
using `with*()`, both new and old instances are sharing the same set of stateful mutable data. It allows, for example,
to get `WebView` via type-hinting in a controller and change context path:
```php
final class BlogController {
private WebView $view;
public function __construct (WebView $view) {
$this->view = $view->withContextPath(__DIR__.'/views');
}
}
```
and then register CSS in a widget:
```php
final class LastPosts extends Widget
{
private WebView $view;
public function __construct (WebView $view) {
$this->view = $view;
}
protected function run(): string
{
...
$this->view->registerCss('.lastPosts { background: #f1f1f1; }');
...
}
}
```
#### Locale state
You can change the locale by using `setLocale()`, which will be applied to all other instances that used current state
including existing ones. If you need to change the locale only for a single instance, you can use the immutable
`withLocale()` method. Locale will be applied to all views rendered within views with `render()` calls.
Example with mutable method:
```php
final class LocaleMiddleware implements MiddlewareInterface
{
...
private WebView $view;
...
public function __construct (
...
WebView $view
...
) {
$this->view = $view;
}
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
...
$this->view->setLocale($locale);
...
}
}
```
Example with immutable method:
```php
final class BlogController {
private WebView $view;
public function __construct (WebView $view) {
$this->view = $view;
}
public function index() {
return $this->view->withLocale('es')->render('index');
}
}
```
#### Reset state
To get a deep cloned `View` or `WebView` with a reset state use `withClearedState()`:
```php
$view = $view->withClearedState();
```
#### Deep clone
To get a deep cloned `View` or `WebView`, including state cloning, use `deepClone()` method:
```php
$view = $view->deepClone();
```
## Extensions
- [Yii View Renderer](https://github.com/yiisoft/yii-view-renderer) - a wrapper that's used in
[Yii Framework](https://www.yiiframework.com/).
Adds extra functionality for a web environment and compatibility
with [PSR-7](https://www.php-fig.org/psr/psr-7) interfaces.
- [yiisoft/view-twig](https://github.com/yiisoft/view-twig) - an extension that provides a view renderer that will
allow you to use the [Twig](https://twig.symfony.com) view template engine, instead of the default PHP renderer.
