[TYPO3-english] Multidimensional GET-var in reaulurl

[Andreas Wagner]

Hi list,

Is there a way to turn a multidimensional piVar (coming from checkboxes 
in a search form) into a nice looking URL with realurl?

I think I remember seeing something about multiple categories in some 
tt_news reaulurl config some time ago, but now Google doesn't find it 
for me.

My GET vars could look something like this:
&tx_plugin_pi1[key][12]=12&tx_plugin_pi1[key][13]=13

When I use the below realurl configuration, the GET var isn't 
transformed at all:
$TYPO3_CONF_VARS['EXTCONF']['realurl']['www.domain.com']['postVarSets']['_DEFAULT']['keyword'] 
= array(array('GETvar' => 'tx_plugin_pi1[key]'));

If I remember correctly, there should be a way to transform this into 
something like /keyword/12,13/ or something, but I'm just stuck.

Any help appreciated.

Regards,

Andreas
