[kronolith] Running against walls ... hooks&prefs - I need help

[Martin Hochreiter]

Hi!

I am trying to set preferences for an external calender for each user.

I created a config/prefs.local.php in kronolith:

-------------------------------
$_prefs['fb_url'] = array(
     'value' => '',
     'hook' => true,
     'locked' => false
);
$_prefs['display_remote_cals'] = array(
     'value' => '',
     'hook' => true,
     'locked' => false
);
$_prefs['remote_cals'] = array(
     'value' => '',
     'hook' => true,
     'locked' => false
);
-------------------------------

and edited config/hooks.php in kronolith with (working) static return 
values:

------------------------------
if(!function_exists('_prefs_hook_fb_url'))
{
     function _prefs_hook_fb_url()
     {
         return 'blablabla';
     }
}
if(!function_exists('_prefs_hook_display_remote_cals'))
{
     function _prefs_hook_display_remote_cals()
     {
             return 
'a:1:{i:0;s:118:"https://xxxxxxxxxxxxxxxxx/api/dav/Calendars/Users/xxx/Calendar";}'; 

     }
}
if(!function_exists('_prefs_hook_remote_cals'))
{
     function _prefs_hook_remote_cals()
     {
         return     
'a:1:{i:0;a:6:{s:4:"name";s:2:"FH";s:4:"desc";s:0:"";s:3:"url";s:118:"https://xxxxxxxxxxxxxxxxx/api/dav/Calendars/Users/xxx/Calendar";s:5:"color";s:7:"#97d259";s:4:"user";s:0:"";s:8:"password";s:0:"";}}';
     }
}
------------------------------

But - the only entry I get in horde_prefs is the display_remote_cals 
with "a:0:{}",
i dont see any of the other 2 entries and ... have no idea why

please help!

regards
Martin
