register a variable through a hook

[emath]

hey,

im trying to do a realy simple thing - i just want to register a boolean variable that will be avaible in the "search_threadbit" template .

so ive added the following code with the location of "search_results_thread_process" hook :

PHP Code:

$templater->register_page_templates();
if ( strpos($_SERVER['HTTP_REFERER'],'pitronot') !== false ) {
    $diffPrev['bool']=true;
    $templater->register('diffPrev', $diffPreview);
}
else {
    $diffPrev['bool']=false;
    $templater->register('diffPrev', $diffPreview);
} 


though this gives me an error :

Fatal error: Call to a member function register_page_templates() on a non-object in .../packages/vbforum/search/result/thread.php(229) : eval()'d code on line 1

tried to use a class and an object instead of the array, this didnt work neither.

any suggestions?
