Array sizes are inconsistent

[bennyborn]

I have a multilingual shop where all 3 languages are using exactly the same modules and even the products published in these languages are the same. It works for two languages withouth any problem but on the third language I receive the following error in the product list:

ValueError:

I could not figure out why it happens in the first place but $arrProducts contains way more entries than $arrParam[0]

https://github.com/isotope/core/blob/2.9/system/modules/isotope/library/Isotope/Model/Product.php#L562-L563

To fix the problem momentarily I've added a quick hotfix which makes sure that $arrProducts only contains the products listed in $arrParam[0]

// [...]
// -- HOTFIX: Make sure products matches the params
$arrProductsUnique = [];
foreach( $arrProducts as $i => $p ) {

    if( !array_key_exists($p->id, $arrParam[0]) ) {
        continue;
    }

    $arrProductsUnique[$p->id] = $p;
}
$arrProducts = $arrProductsUnique;
// -- HOTFIX

// Add product array as the last item.
// This will sort the products array based on the sorting of the passed in arguments.
$arrParam[] = &$arrProducts;
array_multisort(...$arrParam);

Judging from your stack trace you are still on Isotope 2.8.x. Does the issue occur in Isotope 2.9.0 as well?

[bennyborn]

I'm actually on 2.9.x-dev 6aff607

[fritzmg]

Your error message says

at vendor/isotope/isotope-core/system/modules/isotope/library/Isotope/Model/Product.php:578

The error message cannot originate from 2.9.x-dev 6aff607 as there is nothing in that line:

core/system/modules/isotope/library/Isotope/Model/Product.php

Line 578 in 6aff607

*/

The error message likely originates from Isotope 2.8.17:

core/system/modules/isotope/library/Isotope/Model/Product.php

Line 578 in 2c37561

$arrParam[] = &$arrData[$strField];

[bennyborn]

Sorry for the confusion. I am on 2.9.x-dev 6aff607 but the stack trace was shifted due to some debugging lines 😁
So it is really about array_multisort(...$arrParam);

What do the translations look like? I could imagine that products are translated two two languages but not to all of them? Or one is the fallback?

[bennyborn]

What do the translations look like?

I'm not quite sure what you mean. Some of the product data is translated in all 3 languages, some are not and using the fallback translation.

[aschempp]

Can you maybe screenshot the backend product configuration for all three languages?

[bennyborn]

What configuration do you mean? There are only some core fields that are enabled for translation (name, teaser, description).

[aschempp]

or maybe provide a dump of these products so I can reproduce this locally?
