Ah! That looks much better... complete code below
/**
* site/config.php
*/
$config->appendTemplateFile = '_layout.php';
/**
* site/templates/home.php
*/
$title = $page->title;
$shop = $pages->get('/shops/mr-big');
$mainContent = $shop->render('partials/shop-intro.php', ['appendFile'=>null]);
/**
* site/templates/partials/shop-intro.php
*/
<div class="shop-intro">
<h2><?= $page->title ?></h2>
<?php foreach( $page->shop_photos AS $photo ) : ?>
<img src="<?= $photo->url ?>" /><br/>
<?php endforeach; ?>
<div class="shop-desc">
<?= html_entity_decode($page->shop_description) ?>
</div>
</div>
/**
* site/templates/_layout.php
*/
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title><?= $title; ?></title>
<link rel="stylesheet" type="text/css" href="styles.css" />
</head>
<body>
<h1><?= $title; ?></h1>
<div class="container">
<?= $mainContent ?>
</div>
</body>
</html>
I like it like this...
If anyone has a better way, feel free to jump in.
