some wordpress functions are not working in iss-theme.php file

Hi,

I need to change some things in the plugin to fit my website needs and functionality. So I wrote below code in iss-theme.php file and understood that these functions(is_page_template, is_search, is_tax, is_singular) aren’t working at all inside that file:

$search_refer = $_GET["post_type"];
if(is_page_template('home.php') || (is_search() && $search_refer == 'some-referrer') || is_tax('pd-category') || is_singular('some-post-type')){
     $search_refer = 'referrer1';
}elseif((is_search() && $search_refer == 'some-referrer') || is_page_template('page-supp.php')){
     $search_refer = 'referrer2';
}

What’s the issue please? I need urgent help on this please.
Thanks
