10 | * @param array $pages | |
11 | * Receives an array of pages. For example: | |
12 | * $pages = ["Overview" => ""]; | |
13 | * | |
14 | * So when you call this hook, you must refer to the | |
15 | * parameter by reference. For example: | |
16 | * Hook::func(HOOKTYPE_NAVBAR, 'add_navbar_item'); | |
17 | * | |
18 | * function add_navbar_item(&$pages) // remember the & to use by reference | |

31 | * Putting HTML in this hook is not a good idea. | |
