This is a renderer for rendering PHP view scripts into a PSR-7 Response object. It works well with Slim Framework 3.
Note that PHP-View has no built-in mitigation from XSS attacks. It is the developer's responsibility to use htmlspecialchars() or a component like zend-escaper. Alternatively, consider Twig-View.
Install with Composer:
composer require slim/php-view
use Slim\Views\PhpRenderer;
include "vendor/autoload.php";
$app = new Slim\App();
$container = $app->getContainer();
$container['renderer'] = new PhpRenderer("./templates");
$app->get('/hello/{name}', function ($request, $response, $args) {
return $this->renderer->render($response, "hello.php", $args);
});
$app->run();//Construct the View
$phpView = new PhpRenderer("./path/to/templates");
//Render a Template
$response = $phpView->render(new Response(), "hello.php", $yourData);You can now add variables to your renderer that will be available to all templates you render.
// via the constructor
$templateVariables = [
"title" => "Title"
];
$phpView = new PhpRenderer("./path/to/templates", $templateVariables);
// or setter
$phpView->setAttributes($templateVariables);
// or individually
$phpView->addAttribute($key, $value);Data passed in via ->render() takes precedence over attributes.
$templateVariables = [
"title" => "Title"
];
$phpView = new PhpRenderer("./path/to/templates", $templateVariables);
//...
$phpView->render($response, $template, [
"title" => "My Title"
]);
// In the view above, the $title will be "My Title" and not "Title"Inside your templates you may use $this to refer to the PhpRenderer object to render sub-templates.
You can now render view in another views called layouts, this allows you to compose modular view templates and help keep your views DRY.
Create your layout ./path/to/templates/layout.php.
<html><head><title><?=$title?></title></head><body><?=$content?></body></html>Create your view template ./path/to/templates/hello.php.
Hello <?=$name?>!Rendering in your code.
$phpView = new PhpRenderer("./path/to/templates", ["title" => "My App"]);
$phpView->setLayout("layout.php");
//...
$phpview->render($response, "hello.php", ["title" => "Hello - My App", "name" => "John"]);Response will be
<html><head><title>Hello - My App</title></head><body>Hello John!</body></html>Please note, the $content is special variable used inside layouts to render the wrapped view and should not be set in your view paramaters.
