eID czyli extension ID
• Alternatywna rendering engine TYPO3
• Bardzo okrojone srodowisko TYPO3
– Podstawowe stale systemowe
– Dostep do bazy danych
– localconf.php / ext_localconf.php => czesciowo zaladowane
rozszerzenia bez $TCA

eID – zastosowanie : 1. deklaracja
EXT:myExt/ext_localconf.php
<?php
$TYPO3_CONF_VARS['FE']['eID_include']['hello_eID'] =
'EXT:myExt/eID_myTest.php';
?>

eID - zastosowanie: 2. scrypt
EXT:myExt/eID_myTest.php
<?php
if (!defined ('PATH_typo3conf'))
die ('Could not access this script directly!');
echo 'Hello World at ' . date('c');
?>

eID - zastosowanie: 3. wywolanie
URL:
http://www.myproject.pl/?eID=hello_eID
