[TYPO3-shop] [Typo3-shop] Problem extending tt_products

[Franz Holzinger]

Hello Katharina Zugberg,

Fine, this can be done also by using the Extension Kickstarter.

> When debugging I can see that the ext_localconf.php of my extension is

This is done automatically by TYPO3 as soon as an extension has been
installed.

Check your
t3lib_extMgm::addToAllTCAtypes('tt_products','your_new_field;;;;1-1-1');

You must enter here all your new field names. Otherwise they are not
visible in the backend. It is not enough to add the columns to the TCA.
They must also be added to the
$TCA['tt_products'] = Array (
...
	'types' => Array (
		'0' => Array('showitem' => ';;;;1-1-1,hidden;;1,
title;;2;;3-3-3,subtitle;;5;;3-3-3, itemnumber;;3, category,
price;;4,weight;;6,
note;;;richtext[]:rte_transform[mode=ts_css|imgpath=uploads/tx_ttproducts/rte/],image;;;;4-4-4,datasheet,'
.
			
'--div--;LLL:EXT:tt_products/locallang_db.xml:tt_products.variants,color,size,gradings;;7,description,additional')
	),


of tca.php from tt_products.

Check also via the phpMyAdmin if all new fields are there within the
tt_products table.

Greets,

Franz
