[TYPO3] Problems with typoLink_URL

Wed Mar 26 13:15:58 CET 2008

$conf = array('parameter' => $this->ttNewsSinglePid, 'additionalParams' =>
'&tx_ttnews[tt_news]=' . $this->matchingResult[$index]['uid'],
'useCacheHash' => true,); $url = $this->cObj->typoLink_URL($conf);

This should generate a url to a tt_news article. It's in a for loop, so that
I can output lots of tt_news articles.

$this->matchingResult[$index]['uid'] returns a different number in each
loop, so I know it hast he correct UID fro the article,

but when $url is outputed in an echo it is empty, so the link urls are tot
he current article being viewed instead oft eh article link I made.

When I display the content of $conf I see the correct info, such as:

title = 'Test Article NSN'
uid = '20'
pid = '47'
datetime = '21 March 2008'
author = 'Stephen Bungert'

Why then when I echo $url does it display nothing. Or if I use it in a links
href it links tot he current article being viewed (the current url).

Here is the full extension PHP (I know there are some problems with it - I'm
just trying to get used to writing them first)
