Pripojenie súboru s RTE class:

// Include the htmlArea RTE frontend plugin
require_once( t3lib_extMgm::extPath( 'rtehtmlarea' ).'pi2/class.tx_rtehtmlarea_pi2.php' );

Deklarácia premenných:

	// Declare the following class variables for the RTE API:
	var $RTEObj;
	var $docLarge = 0;
	var $RTEcounter = 0;
	var $formName;
	var $additionalJS_initial = '';// Initial JavaScript to be printed before the form (should be in head, but cannot due to IE6 timing bug)
	var $additionalJS_pre = array();// Additional JavaScript to be printed before the form (works in Mozilla/Firefox when included in head, but not in IE6)
	var $additionalJS_post = array();// Additional JavaScript to be printed after the form
	var $additionalJS_submit = array();// Additional JavaScript to be executed on submit
	var $PA = array( 'itemFormElName' =>  '', 'itemFormElValue' => '', );
	var $specConf = array(
		'rte_transform' => array(
			'parameters' => array(
				'mode' => 'ts_css',
			)
		)
	);
	var $thisConfig = array();
	var $RTEtypeVal = 'text';
	var $thePidValue;

Funkcia pre samotné vytvorenie triedy RTE editora aj s napolnením príslušných šablónových značiek (riadok vyznačený červenou je dôležitý pre správnu funkciu RTE editora v Mozille, konkrétne pri vkladaní textu do RTE zo schránky):

	/**
	 * Parse marks for RTE htmlarea editor in frontend
	 *
	 * @param	array		$markerArray: template markers
	 * @return	array		return: RTE marks
	 */
	function parseMarksRtetextarea( &$markerArray ) {

		// My settings
		$myFormName = 'formCreate';
		$myTableName = 'tx_extname_cv';
		$myFieldName = 'cv';
		$this->postvars = t3lib_div::_POST( $this->prefixId );
		$this->postvars[$myTableName] = preg_replace( '`[\r\n]`', ' ', $this->postvars[$myTableName] );

		// RTE settings
		if( !$this->RTEObj )
			$this->RTEObj = t3lib_div::makeInstance( 'tx_rtehtmlarea_pi2' );
		if( $this->RTEObj->isAvailable() ) {
			$this->RTEcounter++;
			$this->table = $myTableName;
			$this->field = $myFieldName;
			$this->formName = $myFormName;
			$this->PA['itemFormElName'] = $this->prefixId.'['.$myTableName.']';
			$this->PA['itemFormElValue'] = $this->postvars[$myTableName];
			$this->thePidValue = $GLOBALS['TSFE']->id;
			$RTEItem = $this->RTEObj->drawRTE( $this, $myTableName, $myFieldName, $row=array(), $this->PA, $this->specConf, $this->thisConfig, $this->RTEtypeVal, '', $this->thePidValue );
			$markerArray['###ADDITIONALJS_PRE###'] = $this->additionalJS_initial.'
				<script type="text/javascript">'. implode(chr(10), $this->additionalJS_pre).'</script>';
			$markerArray['###ADDITIONALJS_POST###'] = '
				<script type="text/javascript">'. implode(chr(10), $this->additionalJS_post).'</script>';
			$markerArray['###ADDITIONALJS_SUBMIT###'] = implode(';', $this->additionalJS_submit);
			$markerArray['###FORM_RTE_ENTRY###'] = $RTEItem;
			return $markerArray;
		}
	}

Použitie predchádzajúcej funkcie vo FE module (parameter $marks je pole značiek HTML šablóny):

$this->parseMarksRtetextarea( $marks );

HTML šablóna, červenou sú vyznačené značky RTE editora:
