Caretaker

This is a feature request, with a attached diff

For the different views, you might want to add/edit data (eg. contact persons based on instance) to be shown.

For this purpose I've added 3 hooks into the function showNodeInfo() inside EXT:caretaker/pi_base/class.tx_caretaker_pibase.php

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['nodeMarkersData']
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['childMarkersData']
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['rootlineMarkersData']

foreach part of the template rendering.

Attached extension gives a working example. Add the following TypoScript to your template, after you've added the marker ###MYOWNFIELD### to your html template

plugin.tx_caretaker_pi_overview.childMarkers.MYOWNFIELD = TEXT
plugin.tx_caretaker_pi_overview.childMarkers.MYOWNFIELD {
    field = MYOWNFIELD
}
plugin.tx_caretaker_pi_overview.nodeMarkers.MYOWNFIELD < plugin.tx_caretaker_pi_overview.childMarkers.MYOWNFIELD
plugin.tx_caretaker_pi_overview.rootlineMarkers.MYOWNFIELD < plugin.tx_caretaker_pi_overview.childMarkers.MYOWNFIELD

To see the marker ###MYOWNFIELD### be replaced with the text "my own data from somewhere" as written in the function additionalData (look in ext_localconf.php)

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['nodeMarkersData'][$_EXTKEY] = 'EXT:dkm_caretaker/class.tx_dkmcaretaker_hooks.php:&tx_dkmcaretaker_hooks->additionalData';

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['childMarkersData'][$_EXTKEY] = 'EXT:dkm_caretaker/class.tx_dkmcaretaker_hooks.php:&tx_dkmcaretaker_hooks->additionalData';

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['caretaker']['rootlineMarkersData'][$_EXTKEY] = 'EXT:dkm_caretaker/class.tx_dkmcaretaker_hooks.php:&tx_dkmcaretaker_hooks->additionalData';
