Simple WordPress login/logout shortcode

gistfile1.txt

if ( ! function_exists('wpex_loginout_shortcode') ) {
  function wpex_loginout_shortcode( $atts ) {
		extract( shortcode_atts( array(
			'login_url'		=> wp_login_url(),
			'log_in_text'	=> __( 'log in', 'wpex' ),
			'log_out_text'	=> __( 'log out', 'wpex' ),
		), $atts ) );
		if ( is_user_logged_in() ) {
			$url = wp_logout_url( home_url() );
			return '<a href="'. $url .'" title="'. $log_out_text .'">'. $log_out_text .'</a>';
		} else {
			$url = $login_url;
			return '<a href="'. $url .'" title="'. $log_in_text .'">'. $log_in_text .'</a>';
		}
	}
	add_shortcode( 'loginout-link', 'wpex_loginout_shortcode' );
}

Simpler if we dont care about labels

add_shortcode('login',function(){
   $url = wp_login_url();
		if ( is_user_logged_in() ) {
			$url = wp_logout_url( home_url() );
			return "<a href='$url'> Logout</a>";
		} else {		
			return "<a href='$url'>Login</a>";
		}
});

will this ask for confirmation?

@sobhy0101 - All this does is create a link to the WordPress login page if you want logout confirmation you need to hook into the WordPress action that runs before logging out to create such confirmation. I'm sure there are plugins out there that do this.

Sorry for not being clear before. Will this logout asks for a confirmation before redirecting to the URL?

@sobhy0101 - No, because WordPress doesn't have any confirmation built-in by default.
