overwrite wordpress function in site.php?

Hey there,

I wanted to future-proof a few modifications I have in wordpress.php. One example is the function:

PHP:

    function getDisplayName(User $user)
    {
        switch ($this->getConfig('display_name', 'username'))
        {
            case 'name_f_name_l' : return $user->name_f . ' ' . $user->name_l;
            case 'username' :
            default:
                return $user->login;
        }
    }

I'd like to modify this to create an option for Last, First. Can I do this in site.php somehow so that future upgrades will not overwrite the changes?

Thanks!

I should add, the function is something like this, but I just want to not edit the code directly:

Code:

    function getDisplayName(User $user)
    {
        switch ($this->getConfig('display_name', 'username'))
        {
            case 'name_f_name_l' : return $user->name_f . ' ' . $user->name_l;
            case 'name_l_name_f' : return $user->name_l . ', ' . $user->name_f;
            case 'username' :
            default:
                return $user->login;
        }
    }

thanks for wonderful guidline

I will admit I know nothing, absolutely nothing, about Wordpress but if that function is part of the Wordpress script I would think site.php - which is a part of aMember - will have no control over it.

Hi there, actually that function lives in /amember/application/default/plugins/protect/wordpress/wordpress.php - I'm just trying to find a way to modify the function slightly without editing the code directly. As I understand it, site.php for amember is for custom functions, can I add this there? Thanks-
