How can I hide that ‘course or call’ category from the page..
I have var_dump the variable which is passing as parameter to query_posts
$args = jr_filter_form();
var_dump($args);
query_posts($args);
This category is having tag_ID="69" in its url , which I have seen in WordPress dashboard, job category page.
Always check the WordPress codex, it’s your friend 🙂
It is detailed in the query_posts documentation here
I would however recommend against using query_posts. See this for some detail.
get_posts is more likely what you need – and a quick Google will give you this example.
