[TYPO3-project-formidable] include dynamic XML

[Jerome Schneider]

Hello Tonni,

What you need is the xmlbuilder, which is the (really simplier) 
equivalent of DOM in javascript

This feature is not published for the moment as it is still in 
developpment, but here is how to add it to your version of formidable 
until next release:


STEP 1:
in File: ameos_formidable/api/class.tx_ameosformidable.php
in method: _compileConf
-> just before      return $aConf;   add this line:



$aConf = $this->_insertXmlBuilder($aConf);



---------------------------------------------

STEP 2:
in the same file
somewhere in the class definition, add this method

function _insertXmlBuilder($aConf, $aTemp = array()) {
	
	reset($aConf);
	while(list($key, $val) = each($aConf)) {

		if(is_array($val)) {

			if(t3lib_div::isFirstPartOfStr($key, "xmlbuilder")) {

				$aTemp = $this->array_add(
					$this->_callUserObj($val),
					$aTemp
				);

			} else {
				$aTemp[$key] = $this->_insertXmlBuilder($val);
			}
		}
		else {
			$aTemp[$key] = $val;
		}
	}
	
	return $aTemp;
}



--------------------------------------------

That's all for the patch.

USAGE:
Place an xmlbuilder tag wherever you want in the XML ( in your case we 
need renderlets, so it will be in <elements></elements> tag )
Like this:

<xmlbuilder>
	<userobj>
		<php><![CDATA[

			$aXml = array();

			$aSomeCollection = array(
				"lboxone" => "My first listbox",
				"lboxtwo" => "My second one",
				"lboxthree" => "My third one",
			);

			reset($aColumns);
			while(list($sName, $sLabel) = each($aSomeCollection)) {
				
				$aXml["renderlet-somenamespace-" . $sName] = array(
					"type" => "LISTBOX",
					"name" => $sName,
					"label" => $sLabel,
					"data" => array(
						"items" => $this->_arrayToRdtItems(
							array(
								"option_a" => "I prefer A",
								"option_b" => "Gimme a B",
								"option_rand" => "Random is better: " . rand(),
							)
						)
					),
					/* whatever config you need ... */
				);

			}

			return $aXml;

		]]></php>
	</userobj>
</xmlbuilder>



All the possible xml configuration described in the Formidable 
documentation can be translated to a php array for dynamic form buiding 
that way.

Hope this helps ( and does not sux too much :D )

PS: the php method and xml exemples are also included in attachements to 
this post for your convenience
