The parameter "id" must be defined


When I try to access my subpage, this error pops-out

The parameter "id" must be defined.

Code I used to do this

default.html.php

<div class="post-preview">
    <a href="<?= $this->path('blogpost', [
                    'id' => $blogpost-> getId(),
                    'title' => $blogpost -> getTitle(),
            ]); ?>">

defaultcontroller.php

 public function blogarticleAction($id){
     $this->view->blogarticle = \Pimcore\Model\DataObject\Blogpost::getById($this->getParam("id"));
}

RegEx set up:

ofcourse I created blogarticle.html.php in the same folder as default.html.php


Solution

  • Use $id from action, not from container

    public function blogarticleAction($id){
         $this->view->blogarticle = \Pimcore\Model\DataObject\Blogpost::getById($id);
    }
    

    $this->getParam("id") Will look in the container a parameter named id, which is not what you want

    You should read https://symfony.com/doc/current/routing.html which explains about route parameters
