Snippet

Get all snippet arguments

We can send arguments to a snippet. We can also get all the arguments from inside the snippet.

Template / snippet

snippet('my-snippet', ['car' => true, 'boat' => false]);

Snippet

print_r(get_defined_vars()['_data']);

Results

array(
  'car'  => true
  'boat' => false
)

Snippet preview

To preview snippets outside the normal pages is not as simple as it seems.

Except reading the html, it also needs to read the page $page object. That require the snippet to know which template to use.

Function needed

It takes $template, $data and $page. It returns a html output.

class SnippetPreview extends Kirby\Component\Template {
  public function render($template, $data = [], $page = null) {
    $file = $template;
    $data = $this->data($page, $data);

    if(!file_exists($file)) {
      throw new Exception('The template could not be found');
    }

    $tplData = tpl::$data;
    tpl::$data = array_merge(tpl::$data, $data);
    $result = tpl::load($file, null);
    tpl::$data = $tplData;

    return $result;
  }
}

How to use it

First we declare our class to a variable. Then we use render with a snippet, an empty array and a page object. The class is asking for a template, but we can send a snippet as well.

$SnippetPreview = new SnippetPreview(kirby());

$data = $SnippetPreview->render(
	kirby()->roots()->snippets() . DS . 'menu.php',
	array(),
	page('about')
);

echo $data;
