How can I tell if I'm on a login page?

Question

There are functions for is_home(), is_blog() is_single() etc...

What's the best way to tell if I'm on a page that is requesting that I login? I guess that would just be the wp-login.php page.

Answer 1

Paste this function in your functions.php or a plugin file:

function is_login_page() {
    return in_array($GLOBALS['pagenow'], array('wp-login.php', 'wp-register.php'));
}

and then you can use it like this:

if(is_login_page()){
  //this is a login page
}else{
  //not the page you are looking for
}
