[TYPO3-dev] About empty cHash

[Francois Suter]

Hi,

> can you show how you create the links?

Sure. In the TS setup of pi1, there's something like:

plugin.tx_vgetagcloud_pi1 {
	tagWrap {
		dataWrap = <li style="font-size: {field:tag_style}%">|</li>
		typolink {
			parameter.data = field:tag_link
			additionalParams.dataWrap = 
&tx_vgetagcloud_pi2[pages]={field:tag_pages}&tx_vgetagcloud_pi2[keyword]={field:tag_keyword}
			ATagParams.dataWrap = id="tag{field:tag_id}" title="{field:tag_keyword}"
		}
	}
}

This TS is then used on each keyword by calling:

$tags[] = $this->cObj->stdWrap($aKeyword,$this->conf['tagWrap.']);

The reason for using such a TS setup is to be very flexible as to what 
kind of link you put on each keyword. Instead of pointing to a page 
containing the pi2, it could point to the indexed search engine, the 
news search engine, etc.

In the meantime I have found another solution which is equivalent in my 
case, as fas as I can tell.

My pi2 expect only 2 possible parameters. The empty cHash thing occurs 
obviously when both are empty. So if I catch this condition with a test 
and call $GLOBALS['TSFE']->set_no_cache(); I arrive at the same result 
that if the cHash parameters was passed and 
$GLOBALS['TSFE']->set_no_cache(); were called by 
$GLOBALS['TSFE']->reqCHash();

Unless I've got it wrong... :-)

Cheers
