JSON_LD Code in Layout-File

1

To provide structured data for Google, I followed Schema-Markup für Rezepte | Google Search Central  |  Documentation  |  Google for Developers and inserted some code into the head area in the layout-file to provide the data for Google:

 <head>
<?= $this->Html->charset() ?>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>
        <?= $cakeDescription ?>
        <?php
          //  if (isset($pageTitle) AND !empty($pageTitle)) {
           //     echo ' - '.$pageTitle;
           // }
        ?>
        <?php
            //echo $this->fetch('title');
        ?>
    </title>
    
    <?= $this->Html->meta('icon','favicon.svg',['type' => 'image/svg+xml'])?>
    <?= $this->Html->css(['stylesheet']) ?>
    <?php $this->Html->script('searchRecipes', ['block' => 'scriptBottom']); ?>

   
    <?= $this->fetch('meta') ?>
    <?= $this->fetch('css') ?>
    <?= $this->fetch('script') ?>

For me it seems to be overkill, because the whole code-block is only needed, if the the action “showrecipe” is called.
Is there a way to put this code into a separate file and call it from the method “showrecipe” in controller “recipes”?

In your layout, put <?= $this->fetch('googlepart') ?>, and then in the template for anything that needs to have Google code you would have

$this->start('googlepart');
// all your code to generate that block
$this->end();

Thank you very much for your help!
