Hi All,

I have solved this issue myself. Please have a look to my modified code.

Note : First important thing is that you must write you rewrite rule , filter query var and flush rewrite rule only in plugin activation hook.

register_activation_hook(__FILE__, “call_rewrite_fun”));

function call_rewrite_fun() {

// Filter query var
init_query_vars();

// Add rewrite rule
add_endpoints();

// Flush
flush_rewrite_rules();
}

you should use template_redirect hook for using get_query_var() function.

Thanks,
Darik
