[Typo3] Back link?

[Christopher]

Hi,

There may be an all-Typoscript solution to this (I couldn't think one up though), but you can use TS and a bit (one line!) of php scripting to get this kind of link:

Typoscript parts:
==============================

### Include the file with any php functions necessary into the page:
page.includeLibs.library = fileadmin/scripts/userFunctionLibrary.inc

### Then create a typolink using the output of a php function:
###
### For more information on the stdWrap property 'preUserFunc', see the TSref:
### http://typo3.org/documentation/document-library/doc_core_tsref/stdWrap/
### And for more information on the 'typolink' function, see the TSref again:
### http://typo3.org/documentation/document-library/doc_core_tsref/typolink/

lib.backLink  = HTML
lib.backLink {
  value = &laquo Previous Page
  value.typolink.parameter.preUserFunc = user_referer
}


PHP Parts:
==============================
<?php
	// Not much to this; get the http referer using the appropriate Typo3 API function.
	// For more information about the getIndpEnv() function - and the reasons for using it - see the API docs:
	//http://typo3.org/documentation/document-library/doc_core_api/High_priority_functi/
	function user_referer() {
		$content = t3lib_div::getIndpEnv('HTTP_REFERER');
		return $content;
	}	
?>
