How to detect current page

Hello,

I am a wordpress developer. I need to detect if the current page is “Activate”. I am trying following code but its not working when any user click on their activation link from their email address:

function my_redirect() {

if ( is_page( array( 38, ‘activate’, ‘Activate’ ) ) ) {
//Do stuff here..
}

}
add_action( ‘template_redirect’, ‘my_redirect’ );

Is there any other way so that I can detect if the current page is Activate or not?

Thanks in advance.
Sam
