Question

I\'m trying to get the current user info in my plugin using the func wp_get_current_user(). But am getting Call to undefined function wp_get_current_user()

Answer 1

As crazy as this might sound, the problem in my application was happening because I had a FILE called menu.php where I had a class to create Wordpress menus.

Literally, simply changing the name of the FILE from menu.php to nav-menu.php, fixed the issue. I replicated the issue 3 times because I could not believe the name of the FILE could be the problem.

Just in case somebody would like to now what was inside that file, here it is:

class OwNavMenu extends OwCpnt 
{
    function __construct( $location, $args ) {
        $show = $args['show'];
        $span = $args['span'];   

        if ( $show ) {
            $this->menu( $location, $span );
        }     
    }

    function menu( $location, $span ) {
        if ( $location ) {
            echo '
';
                wp_nav_menu(
                    array(
                        'theme_location'  => $location,
                        'link_before'     => ( $span ) ? ''  : '',
                        'link_after'      => ( $span ) ? '' : ''
                    )
                );
            echo '
';
        }        
    }
}
