Plugin: Custom menu item problem

Question

I'm using the following snippet to add a menu item:

<?php
add_menu_page(
    'Foo Server',
    'Foo Server',
    'manage_options',
    'foo-server',
    array('Class', 'method')
);
?>

Fine, it's displayed. But clicking on it returns:

You do not have sufficient permissions to access this page.

I really don't know what to do.

Any idea? Thanks

UPDATE: Problem fixed. I was registering the menu using the wrong hook:

add_action('admin_init', 'function that runs the above code!');

must be:

add_action('admin_menu', 'function that runs the above code!');

Thanks.

Answer 1

Hook into 'admin_menu' to register menu pages. And next time prepare your question better.

Answer 2

Do your WordPress Database Tables use wp_ as a prefix? I've read several articles that using a different prefix can cause the permissions error.

Answer 3

If you're calling this from inside a Php Class, then you're using the wrong syntax:

add_menu_page(
    'LiveHelp Server',
    'LiveHelp Server',
    'manage_options',
    'livehelp-server',
    // Call the  the method/function from inside a class
    array( __CLASS__, 'method_name' )
    // Another way to call the method/function from inside a class
    array( &$this, 'method_name' )
    // Another way to call the method/function from inside a class
    ClassName::method_name
);

Be sure that your method/function is really named method() (which is a bad idea). Else it won't work.

I guess you're simply calling it from inside a function, so it's enough to name the callback function (without a class).
