[TYPO3-english] need help on customizing TCA

[Santiago]

Hello,

Thanks for pointing this out!

Don't know, whether I understand it right, but at closer look to tca.php it 
looks quite risky to me.

tca.php assumes, that ext_tables.php has already been evaluated, but it 
contains exactly the same assignment:

$TCA['myx'] = array( ... )

so when the interpreter sees the assignment operator it might be a trigger to 
allow garbage collection, which would result in nasty debugging sessions.

Even if you assume, that the assignment is the last operation from that 
statement, it stil looks suboptimal to me.
Wouldn't it be right to use 'array_merge' or the array-element assignments of 
the second level like:

$TCA['myx']['interface'] = array( ... );
$TCA['myx']['columns'] = array( ... );
$TCA['myx']['types'] = array( ... );
$TCA['myx']['palettes'] = array( ... );

Thanks a lot for that hint! Will dive into ...


kind regards
