[TYPO3-english] cObj (IMAGE) in backend module

["Christian Müller (Kitsunet)"]

Hi Søren,

Happy New Year!

cObj relies heavily on TSFE, so you need a full TSFE in backend to get a 
cObj. Alternative would be to look at tslib_gifbuilder directly.

a fire and forget function to get TSFE in backend that I have stored 
away is this, put it into your BE class or as I do in into a "lib_div" 
as static function:

function buildTSFE($pid = 1) {

		//needed for TSFE
		require_once(PATH_t3lib.'class.t3lib_timetrack.php');
		require_once(PATH_t3lib.'class.t3lib_tsparser_ext.php');
		require_once(PATH_t3lib.'class.t3lib_page.php');
		require_once(PATH_t3lib.'class.t3lib_stdgraphic.php');

		require_once($BACK_PATH.'sysext/cms/tslib/class.tslib_fe.php');
		require_once($BACK_PATH.'sysext/cms/tslib/class.tslib_content.php');
		require_once($BACK_PATH.'sysext/cms/tslib/class.tslib_gifbuilder.php');
		/* Declare */
		$temp_TSFEclassName = t3lib_div::makeInstanceClassName('tslib_fe');

		/* Begin */
		if (!is_object($GLOBALS['TT'])) {
			$GLOBALS['TT'] = new t3lib_timeTrack;
			$GLOBALS['TT']->start();
		}

		if (!is_object($GLOBALS['TSFE']) && $pid) {
			//*** Builds TSFE object
			$GLOBALS['TSFE'] = new 
$temp_TSFEclassName($GLOBALS['TYPO3_CONF_VARS'],$pid,0,0,0,0,0,0);

			//*** Builds sub objects
			$GLOBALS['TSFE']->tmpl = t3lib_div::makeInstance('t3lib_tsparser_ext');
			$GLOBALS['TSFE']->sys_page = t3lib_div::makeInstance('t3lib_pageSelect');

			//*** init template
			$GLOBALS['TSFE']->tmpl->tt_track = 0;// Do not log time-performance 
information
			$GLOBALS['TSFE']->tmpl->init();

			$rootLine = $GLOBALS['TSFE']->sys_page->getRootLine($pid);

			//*** This generates the constants/config + hierarchy info for the 
template.

			$GLOBALS['TSFE']->tmpl->runThroughTemplates($rootLine,$template_uid);
			$GLOBALS['TSFE']->tmpl->generateConfig();
			$GLOBALS['TSFE']->tmpl->loaded=1;

			//*** Get config array and other init from pagegen
			$GLOBALS['TSFE']->getConfigArray();
			$GLOBALS['TSFE']->linkVars = 
''.$GLOBALS['TSFE']->config['config']['linkVars'];

			if 
($GLOBALS['TSFE']->config['config']['simulateStaticDocuments_pEnc_onlyP'])
			{
				foreach 
(t3lib_div::trimExplode(',',$GLOBALS['TSFE']->config['config']['simulateStaticDocuments_pEnc_onlyP'],1) 
as $temp_p)
				{
					$GLOBALS['TSFE']->pEncAllowedParamNames[$temp_p]=1;
				}
			}
			//*** Builds a cObj
			$GLOBALS['TSFE']->newCObj();
		}
}
