[TYPO3-project-formidable] How to have hidden fields with a fixed value?

[Oliver Klee]

Hi,

I'm trying to build a semi-two-page form. For this, I use the submit
button of the first page to call a user function which then sets a
variable. My _render function now checks for this variable and then
re-inits the form with a different template (for the second form).

Now I'd like to check whether the *second* form has been submitted. For
this, I'd like to have a hidden variable with a fixed value (that gets
used even when the first form (and thus the complete form) has already
been submitted once). If I understand it correctly, hidden fields take
their value from the POST data if the form has already been submitted,
so I cannot use the default value for the fixed value.

May code looks like this:

[first form]

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<formidable version="0.5.0">
	<meta>
...
	</meta>
	<control>
		<datahandler:RAW>
			<parentcallback>showConfirmationPage</parentcallback>
		</datahandler:RAW>
		<renderer:STANDARD>
		</renderer:STANDARD>
	</control>
...


PHP code:

	/**
	 * Shows the confirmation page.
	 *
	 * @param	array		the entered form data with the field names as array
keys (including the submit button ...)
	 *
	 * @access	public
	 */
	function showConfirmationPage($parameters) {
		$this->isConfirmationPage = true;

		return;
	}

	/**
	 * Initializes the create/edit form.
	 *
	 * @access	protected
	 */
	function _initForms() {
		$this->oForm =& t3lib_div::makeInstance('tx_ameosformidable');

		$xmlFile = (!$this->isConfirmationPage) ?
			'registration_editor.xml' : 'registration_editor_step2.xml';

		$this->oForm->init(
			$this,
			t3lib_extmgm::extPath($this->extKey).'pi1/'.$xmlFile,
			$this->iEdition
		);

		return;
	}


	/**
	 * Creates the HTML output.
	 *
	 * @return 	string		HTML of the create/edit form
	 *
	 * @access	public
	 */
	function _render() {
		$result = $this->oForm->_render();
		// For the confirmation page, we need to reload the whole thing.
		if ($this->isConfirmationPage) {
			$this->_initForms();
			$result = $this->oForm->_render();
		}
		return $result;
	}


The second form:

<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<formidable version="0.5.0">
	<meta>
...	</meta>
	<control>
		<datahandler:RAW>
			<parentcallback>processRegistration</parentcallback>
		</datahandler:RAW>
		<renderer:STANDARD>
		</renderer:STANDARD>
		<actionlets>
			<actionlet:REDIRECT>
				<url>
					<userobj>
						<extension>this</extension>
						<method>getThankYouAfterRegistrationUrl</method>
					</userobj>
				</url>
			</actionlet:REDIRECT>
		</actionlets>
	</control>


(and all fields from the first page as hidden fields so that the data is
kept)


I'd like to detect when the second page has been submitted - either with
hidden fields or any other way. How could I do this?

Thanks in advance,


Oliver
