Shopping Cart Error 500

Using Neos & Flow Flow App Development
1

Hey guys,

I added some Articles in an array. This works fine, but if I check the page with the MiniCart Module I get the right output at the first call. Then I refresh the page an get an Error 500. Only since PHP 7.1

<?php
namespace NeosCommerce\Cart\Controller;

/*
 * This file is part of the NeosCommerce.Cart package.
 */

use Neos\Flow\Annotations as Flow;
use Neos\Flow\Mvc\Controller\ActionController;

/**
 * @Flow\Scope("session")
 */
class CartController extends ActionController
{

/**
 * @var array
 */
protected $items = array();

/**
 * @Flow\Inject
 * @var \NeosCommerce\Cart\Domain\Repository\CartRepository
 */
protected $cartRepository;

/**
 * @param integer $title
 * @return void
 * @Flow\Session(autoStart = TRUE)
 */
public function addtoAction($title) {

    $cart = $this->items;

    $article = array();
    $article[] = array("title"=>$articleTitle);

    $this->redirectToUri('/');

}

/**
 * @return void
 */
public function miniCartAction() {

    $cart = $this->items;

    if ($cart==false) {
        $sum = "";
        $sum = intval($sum);
        foreach ($cart as $dat) {
            $quantity = intval($dat["quantity"]);
            $sum += $quantity;
        }
        $this->view->assign('itemscount', $sum);
        $this->view->assign('items', $cart);
    } else {
        $this->view->assign('itemscount', '0');
        $this->view->assign('items', '0');
    }

}

}

Okay, I have found this in the error.log but I do not understand it. Can you help me?

What you definitely do there is mix variable types. your items variable is either an array or a string with 0 in it. You should adjust that, asme for itemscount. Also how can $cart ever be false?

Thx Christian, I’ve fixed this. But it does not work. I think, it is an issue with PHP 7.1. It works with PHP 7.0

The line in the apache error log:

FastCGI: server “/usr/lib/cgi-bin/php71-fcgi-www” stderr: PHP message: PHP Fatal error: TYPO3Fluid\Fluid\View\AbstractTemplateView::getCurrentParsedTemplate(): The script tried to execute a method or access a property of an incomplete object.

Christian, sorry.
The problem was the configuration of the webserver.

Thx for your help!

6

Would you explain what it was and how you fixed it? Might help others with similar problems. :slight_smile:

7

With pleasure!
First a little modification in php.ini: session.auto_start = 1
Second: Restart the box :slight_smile:

8

It was not the solution. After the restart it worked. But after a short time it does not work anymore. I just added a <strong> tag in the template and get a 500 error again :frowning:

9

So restarting was probably what fixed it. Could it be that your OPCache settings are broken maybe?

10

OPCache is disabled :frowning:
I don’t understand this, but this Code is in use in an old “TYPO3” Neos and it works.
First I think PHP 7.1 makes problems, but I have the same php.ini settings as in PHP 5. I have no idea anymore.

11

I add this in the Controller Action (at end):
return $this->view->render("../Cart/MiniCart");

It works now. Then I add this

`<f:link.action action="removeAll" controller="Cart">Warenkorb löschen</f:link.action>`

in the MiniCart Template. Nothing works.

I get:
An exception was thrown while Neos tried to render your page
Argument “class” has already been defined, thus it should not be defined again.

I think it is a serialize() unserialize() problem as the error message describes.
