Question

I tried to implement hook_menu in drupal.

function menufun_menu() {
    $items['menufun'] = array(
        'title' => 'Menu Fun',
        'title callback' => 'menufun_title',
        'page callback' => 'menufun_greeting',
        'file' => 'menufun_greeting.inc',
        'page arguments' => array('aaa', 'bbb', 'ccc', 'ddd'),
        'access callback' => 'user_access',
        'access arguments' => array('receive greeting'),
        'type' => MENU_NORMAL_ITEM,
        'weight' => -1,
    );

    $items['menufun/farewell'] = array(
        'title' => 'Farewell',
        'page callback' => 'menufun_farewell',
        'file' => 'menufun_greeting.inc',
        'access callback' => 'user_access',
        'access agruments' => array('receive greeting'),
        'type' => MENU_NORMAL_ITEM,
    );

    return $items;
}

However, the code above will case these 2 errors:

Notice: Undefined offset: 0 in _menu_check_access() (line 619 of /Applications/XAMPP/xamppfiles/htdocs/drupal/includes/menu.inc).
Notice: Undefined offset: 1 in _menu_check_access() (line 619 of /Applications/XAMPP/xamppfiles/htdocs/drupal/includes/menu.inc).

The above 2 errors will not show up if i change

'access callback' => 'user_access',

to

'access callback' => TRUE,

But I already login as administrator, and I give the access permission to all users, and I tried to reload the module, tried to reinstall drupal so that make the database clean, but I still got the same errors, any advices?

Answer 1

You spelled “arguments” wrong in the second menu definition.

'access agruments' => array('receive greeting'),

Should be

'access arguments' => array('receive greeting'),

When you switched it to 'access callback' => TRUE, it ignored the arguments because it was told that it didn’t need to do any checks, but with an actual callback it tried to find the access arguments but can’t.
