Need to check if user is on a particular page

It’s not a post, just the mysite.com/what-we-do page.

Refer to is_page().

<?php
if ( is_page( 'what-we-do' ) ) {
    // We're on the What We Do page
    // do something
}
?>

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
