TYPO3 Core

fortgort to mention the page where the warning apears:
typo3/sysext/cms/layout/db_layout.php

Warning: Invalid argument supplied for foreach() in /var/lib/typo3/typo3_src-3.8.0/typo3/sysext/cms/layout/class.tx_cms_layout.php on line 390

<cite>
I uncommented the line in typo3conf/extTables.php:
$GLOBALS['TCA']['tt_content']['columns']['image']['config']['max_size'] = 10*1024;
coming with version 3.8.0.
</cite>

Which package does carry this file? Are u sure it came with a official TYPO3-package?

Actually that does not seem like an appropriate action to me right now...
maybe put in a check if it is a good idea to spit this $TCA into CMS TYPO3 without in care. ;). have you tried adding t3lib_div::loadTCA('tt_content'); and not using $GLOBALS?

But then, if it is a file from the distribution, then it should work, you're right...

I've tried it on 3 different servers now. Always with the dummy-package. I downloaded the package and the sources from the official typo3.org website. Everytime the same error. So to me it looks really like a bug.

What do you mean with "appropriate action"? This comes with the 3.8.0 release by default in typo3conf/extTables.php. I just did what is written in the comments:

/** * Overriding $TCA * * The TYPO3 Configuration Array (TCA) is defined by the distributed tables.php and ext_tables.php files. * If you want to extend and/or modify its content, you can do so with scripts like this. * Or BETTER yet - with extensions like those found in the typo3conf/ext/ or typo3/ext/ folder. * Extensions are movable to other TYPO3 installations and provides a much better division between things! Use them! * * Information on how to set up tables is found in the document "Inside TYPO3" available as a PDF from where you downloaded TYPO3. * * Usage: * Just put this file to the location typo3conf/extTables.php and add this line to your typo3conf/localconf.php: * $typo_db_extTableDef_script = 'extTables.php';

// Raise upload limit for images in 'image' content-elements to 10*1024 bytes = 1MB
#$GLOBALS['TCA']['tt_content']['columns']['image']['config']['max_size'] = 10*1024;

1. $GLOBALS['TCA']['tt_content']['columns']['starttime']['config']['eval'] = 'datetime';
2. $GLOBALS['TCA']['tt_content']['columns']['endtime']['config']['eval'] = 'datetime';
3. $GLOBALS['TCA']['pages']['columns']['starttime']['config']['eval'] = 'datetime';
4. $GLOBALS['TCA']['pages']['columns']['endtime']['config']['eval'] = 'datetime';

Hi Arne,
as Peter already pointed out, you have to use the t3lib_div::loadTCA method.
You can find some examples here:
http://typo3.org/documentation/document-library/doc_core_api/Extending_the_TCA_a/
there is also some extension setting the max image size to some higher value in TER - you can look there how it was done.
Closing this bug, if there is some new information, please reopen.
