Conimex import fails when collection is empty

[michaelborn]

I get a warning "Warning: Undefined array key "order" after running a conimex import:

./bin/console -vvv conimex:import my-site-export-2022-08-08.yaml

I believe this is a new / more strict warning in PHP 8?

Details

• Bolt 5.0.6
• PHP 8.1.8

Reproduction

./bin/console -vvv conimex:import my-site-export-2022-08-08.yaml

conimex:import <filename>

Steps to reproduce

Evidently, importing a conimex import which does not include the order key.

Expected result

I expected that my content would import.

Actual result

A failed import, with no ability to skip the warning.

It's worth noting that this same export also fails in Bolt 5.1.12 on PHP 7.4. (Albeit with a slightly different error message.) So this is not just a PHP 8 issue, as I previously thought.

// Importing ContentType content

conimex:import <filename>

[michaelborn]

I'm guessing this is a case of an old conimex version, and not an issue in Bolt Core.

I can see the order set on the collection field in the Conimex extension here:

https://github.com/bobdenotter/conimex/blame/04f0d30dd4d038177080519f7bbea1af0f5bd5aa/src/Import.php#L224

[michaelborn]

Nope - this still occurs on the latest conimex v 2.1.2. Unsure whether the issue is in conimex or in bolt/core.

[michaelborn]

I still don't know if this is a Conimex bug or a Bolt core bug, but I was able to fix by adding a check for array length in the collections array in ContentEditController.php:

        if (isset($formData['collections'])) {
            foreach ($formData['collections'] as $collectionName => $collectionItems) {
                if ( !count( $collectionItems ) ) continue; // NEW LINE HERE

This prevents line 433 from flipping out (pun!) because $collectionItems['order'] doesn't exist.

https://github.com/bolt/core/blob/master/src/Controller/Backend/ContentEditController.php#L433

Is this a newbie fix, or should I PR this?
