[TYPO3-english] Plugin Development

[Kay Strobach]

Hello guys,

I'm currently having some problem with changing TSconstants as non 
privileged user.
The problem came up during the development of a customer management 
solution in typo3, which enables typo3 to handle many customers in one 
installation.

Systemenvironment:
	TYPO3 4.2.8
	Templavoila
	PHP 5.x

Project
	CMS for primary and secondary schools germany saxony ;)

Problemdescription:
	The following code works perfectly as BE User with admin=1.
	It should calculates the value of all constants for the fe. And
	changes the one defined with name und sets it to the given
	value.
	
	Is there anyway to make a normal user temporaly admin?
	I thought, that it would be possible to do it with
	$GLOBALS['BE_USER']->user['admin']=1;
	And setting it back to the previous value.
	As seen in the code below.
	The other solution would be a reimplementation of the used
	classes, i would be happy if i could avoid this. And by pass the
	security layer with database queries.


Thanks
Best Regards

function setTSConstantValue($pid,$name,$value) {
	$userStatus = $GLOBALS['BE_USER']->user['admin'];
	$GLOBALS['BE_USER']->user['admin']=1;

	$template_uid = 0;
	$pageId = $pid;
	$tmpl = t3lib_div::makeInstance("t3lib_tsparser_ext");	// Defined 
global here!
	$tmpl->tt_track = 0;	// Do not log time-performance information
	$tmpl->init();

	$tplRow = $tmpl->ext_getFirstTemplate($pageId,$template_uid);
	if (is_array($tplRow) || 1)	{
		$sys_page = t3lib_div::makeInstance("t3lib_pageSelect");

the constants/config + hierarchy info for the template.
		$theConstants = $tmpl->generateConfig_constants();	// The editable 
constants are returned in an array.
		$tmpl->ext_categorizeEditableConstants($theConstants);	// The returned 
constants are sorted in categories, that goes into the $tmpl->categories 
array

will contain key=[expanded constantname], value=linenumber in template. 
(after edit_divider, if any)

cache in tce_main.php)

		$GLOBALS['BE_USER']->user['admin']=$userStatus;
