$incomingFieldArray['colPos'] is accessed before checking if it's available

[magicHatOfTYPO3]

When using PHP 8.1 the DatamapDataHandlerHook fails with an backend error message if colPos is not explicitly provided.

Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1476107295: PHP Warning: Undefined array key "colPos" in /var/www/html/public/typo3conf/ext/content_defender/Classes/Hooks/DatamapDataHandlerHook.php line 51

Hi Nicole, i hit the same issue in your and another extension.
Please see:

Can you tell me is the fix is already released?
(Don't get a clue how to overwatch that here).

I added E_WARNING to be excluded from PHP error reporting, but that did not help:
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_WARNING

Any clue for a workarround until next release?

Thx, Sam

Hi,
I would love to understand the situation and get in insight how to reproduce the problem. If anyone could tell me how to trigger the warning, I can try to fix it.

Hi Nicole,
it's a while ago, but as far as i remember:

• let php "warn" (do not exclude from setting "ERROR_REPORTING in php.ini
• use php 8.1.x
• enable production settings in Typo3
• let it run: open a page with a backendlayout, maybe leaving out some defined colPos or not selected a backendlayout (there i do not know exactly the constellation)

General problem i've got with another ext: the PHP-Warning leads to a Typo3-Exception: The current prozess stops working then. So, best is to avoid warning from the code then, i suggest.

Thank you very much for the awesome content defender!

Cheers, Thomas

Hi @subnoodle

Thank you for your answer. The problem is that I run locally an instance with complete error reporting. But I'm not able to trigger any warning. So I really need some configuration that helps me to run into the problem. I'm using the provided test fixtures (https://github.com/IchHabRecht/content_defender/tree/main/Tests/Functional/Fixtures/TSconfig/BackendLayouts) in my local system.

Hi Nicole,
here it comes again...

In this case, it occures whenever i add a content element, enter some content and click the save button.

The configuration is:
Typo3: 11.5.22
PHP: 8.1.x

Details from Typo3's system -> log
Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1476107295: PHP Warning: Undefined array key "colPos" in /html/typo3/Public/typo3conf/ext/content_defender/Classes/Hooks/DatamapDataHandlerHook.php line 51 | TYPO3\CMS\Core\Error\Exception thrown in file /html/typo3/Public/typo3/sysext/core/Classes/Error/ErrorHandler.php in line 137. Requested URL: https://amer2.bs-dev.work/typo3/record/edit?token=--AnonymizedToken--&edit%5Btt_content%5D%5B313%5D=new&returnUrl=%2Ftypo3%2Fmodule%2Fweb%2Flayout%3Ftoken%3D--AnonymizedToken--%26id%3D313&defVals%5Btt_content%5D%5BCType%5D=header&defVals%5Btt_content%5D%5BcolPos%5D=0&defVals%5Btt_content%5D%5Bsys_language_uid%5D=0&route=%2Frecord%2Fedit

[SYS][belogErrorReporting] = 30711 (chaning it to 0 does not change anything)

Two backendlayouts:
default.typoscript.txt
subpage.typoscript.txt

(renamed for uoload only)

Worked all fine with PHP 8.0. (as far as i remember)

Some automatic typecasts are gone so far i understand possibly the problem, so invalid array keys got critical since then.
Content defender is not the only extension suffering from that.

Any solution & feedback is very appreciated.

Many thanks!
Thomas

Addition: I discoverd and fixed an error on my provided file subpage.typosript:7 and change the line from
rowCount = 3
to correct value:
rowCount = 2

I tought it might help, but the behavior stayed the same (after clearing cache, etc).

Same Problem here, but only when Configuration Preset is in Debug Mode. In Live Mode there is no Problem.
PHP 8.2
TYPO3 11.5.19

Hi all,

I still don't know how to reproduce the problem. Open questions:

• what are you doing, e.g. edit an existing record, saving a new record?
• are you using an admin user or any kind of editor? if an editor role is used, does it have access to the colPos field?

It seems the colPos is missing from the request but I'm unable to reproduce and understand it. I don't want to commit anything "blindly", so I need to be able to trigger the warning by myself. Any hint would be really appreciated.

[anderlk]

Hi Nicole,
I've debugged around a bit.

In Configuration Preset "Live" there is no problem. The problem only comes up in Debug mode.

• When editing an existing record, there is no problem.
• When creating a new record and saving them, the error comes up!

No Matter wich Role. The problem exists for Admins, too.

The PHP version seems to be decisive. With PHP 7.4 the problem does not exist. From PHP 8.0 and up it exists.

I don't know if this helps, but I use content defender in conjunction with the extension: container

But the problem is still here although I have uninstalled the container extension.

Hi @anderlk

Thank you for the further information. I'm still not able to trigger a warning with the current given information. Maybe you can give some additional help.

• can you trigger the warning in a fresh typo3 installation using content_defender (and maybe introduction package)?
• which backend layout is used?
• which user is used?
• which content element is inserted in which column?

Furthermore: a warning isn't any "real" problem. This is why the exception is shown in debug mode only but not in live configuration. This is how TYPO3 works when notices and/or warnings (or other PHP related problems) are triggered.

[anderlk]

Hi Nicole, I have now installed a test system with a fresh typo3 installation with content_defender and introduction package. After the problem did not exist here, I have rebuilt piece by piece my template extension until I found the bug.

Sorry, but it was my own fault. In a completely different TSconfig file the command TCEFORM.tt_content.colPos.disabled = 1 was set.

Why this didn't work with your Extesnion, only in debug mode and how this is related to the PHP version is really a mystery to me?

Thanks for your great help, without which I would not have found the bug.

Maybe has the other reporter a similar problem. Then the bugreport can be closed by me.

@anderlk

Thank you very much for all your effort. With the additional information about the disabled colPos field I was finally able to reproduce and fix the issue!
