View is the V in MVC. A small library to include in your MVC projects. Allows you to separate presentation layer from the rest of your application.
Note: It's your responsibility to check user inputs. This library just renders templates. Nothing else.
Via Composer
$ composer require midorikocak/viewLet's say you have blog post data like this:
$articleData = [
'title' => 'Writing object oriented software is an art.',
'sections' => [
[
'title' => 'Introduction',
'content' => [
'Some people say that you have to be genius, or man,
but they mostly does not undertsand what is humble programming.
Programming should be a modest person\'s craft.',
'Generally those people does exclude others, create clickbait articles,
they make you feel less confident.',
'Do not care about them and just try to create things. Learn. Be hungry.',
],
],
],
'created' => '2020-01-25 00:00:00',
];And you want to render an article using template like this:
// template.php
<?php
if (isset($created) && $created !== '') {
$datetime = strtotime($created);
$formattedDate = date('D, j Y', $datetime);
}
?>
<article>
<?php if ($title !== '') : ?>
<header>
<h2><?= $title ?></h2>
</header>
<?php endif; ?>
<?php foreach ($sections as $section) : ?>
<section>
<?php if (isset($section['title'])) : ?>
<h3><?= $section['title'] ?></h3>
<?php endif; ?>
<?php foreach ($section['content'] as $paragraph) : ?>
<p><?= $paragraph ?></p>
<?php endforeach; ?>
</section>
<?php endforeach; ?>
<?php if ($created !== '') : ?>
<footer>
<time datetime="<?= $datetime ?>">
<?= $formattedDate ?>
</time>
</footer>
<?php endif; ?>
</article>You can use default FileRenderer to extract your php files with variables. And you can render your plain php files with variables:
$renderer = new FileRenderer();
$view = new View($this->renderer);
$view->setTemplate('template.php');
echo $this->view->render($this->articleData);This should output rendered html as this with variables rendered:
<article>
<header>
<h2>Writing object oriented software is an art.</h2>
</header>
<section>
<h3>Introduction</h3>
<p>Some people say that you have to be genius, or man,
but they mostly does not undertsand what is humble programming.
Programming should be a modest person's craft.</p>
<p>Generally those people does exclude others, create clickbait articles,
they make you feel less confident.</p>
<p>Do not care about them and just try to create things. Learn. Be hungry.</p>
</section>
<footer>
<time datetime="1579910400">Sat, 25 2020</time>
</footer>
</article>Note: Extracting variable into runtime can be unsecure.
If you have plain templates with placemarks as {{ someVariable }} you can use
TemplateRenderer
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{ title }}</title>
</head>
<body>
<article>
<header>
<h2>{{ title }}</h2>
</header>
<section>
<h3>{{ sectionTitle }}</h3>
<p>{{ paragraph }}</p>
</section>
<footer>
<time datetime="{{ created }}">
{{ formatted }}
</time>
</footer>
</article>
</body>
</html>To render this template using some data:
$templateRenderer = new TemplateRenderer();
$view = new View($templateRenderer);
$view->setTemplate('tests/View/plain.template.html');
$this->assertNotEmpty($view->render(
[
'title' => 'Object Oriented Programming',
'sectionTitle' => 'Introduction',
'parapgraph' => 'Writing object oriented software is an art.',
'created' => '2020-01-25 00:00:00',
'formatted' => 'Mon 25, 2020',
]
));This should output rendered html as this with variables rendered:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Object Oriented Programming</title>
</head>
<body>
<article>
<header>
<h2>Object Oriented Programming</h2>
</header>
<section>
<h3>Introduction</h3>
<p></p>
</section>
<footer>
<time datetime="2020-01-25 00:00:00">
Mon 25, 2020
</time>
</footer>
</article>
</body>
</html>To use Blade templates, use the included BladeRenderer.
$bladeRenderer = new BladeRenderer('tests/View', '/tmp');
$view = new View($bladeRenderer);
$view->setTemplate('app');
echo $view->render(
[
'title' => 'OOP',
'content' => 'Writing object oriented software is an art.',
]
);To create your own renderer or extend the library with another renderer library, implement RendererInterface
<?php
declare(strict_types=1);
namespace midorikocak\view;
interface RendererInterface
{
public function render(string $template, array $data): string;
}If you have data objects that implement a toArray() method, you can use ViewableTrait with them.
So in your controllers you can write code like this:
$article->template = 'tests/View/posts/post.php';
echo $article->render();You can change the viewer object of your data object by accessing it with the viewer that you initialized using custom renderer.
$templateRenderer = new TemplateRenderer();
$view = new View($templateRenderer);
$article->view = $view;
$article->template = 'tests/View/plain.template.html';
echo $article->render();Please see CHANGELOG for more information on what has changed recently.
