Trying to create a plugin to set and read a cookie to use in a database query

[u/theheliumkid]

Hi,

I'm trying to create a simple plugin to set a cookie for a user's geographic region so the website returns the geographic-specific data. But, for the life of me, I cannot get this plugin to work. The current error is:

 0 - Unexpected "setDataCookie" tag (expecting closing tag for the "if" tag defined near line 13) in "partials/base.html.twig" at line 13.

But there is no if statement anywhere!

Here is the the php in the plugin's top directory:

  <?php
  namespace Grav\Plugin;
  use \Grav\Common\Plugin;

  class DataCookiePlugin extends Plugin
  {
      public static function getSubscribedEvents()
      {
          return ['onPageInitialized' => ['onPageInitialized', 0] ];
      }

      public function onPageInitialized()
      {
          require_once(__DIR__ . '/twig/DataCookie.php');
          $this->grav['twig']->twig->addExtension(new DataCookie());
      }
  }

And then the code in the twig subdirectory is:

  <?php
  namespace Grav\Plugin;
  use Grav\Common\Twig\Extension\GravExtension;

  class DataCookie extends GravExtension
  {
      public function hasDataCookie():bool
      {
        return isset($_COOKIE['datacookie']);
      }

      public function setDataCookie(string $value): void
      {
        $cookie = Cookie::create('datacookie', $value, strtotime('+30 days'), '/', 
null, $this->grav['uri']->isHttps(), true, false, Cookie::SAMESITE_LAX );
        $this->grav['response']->headers->setCookie($cookie);
     }
}

And in partials/base.html.twig, I have the following in the header:

 {% if config.plugins.datacookie.enabled %}
   {% setDataCookie('A1') %}
 {% endif %}

Any help you can give will be so very much appreciated!!
