I need more information about get_site_option()
, update_site_option()
and add_site_option()
.
In codex they say it's the same as single install except that in multisite, it returns the network-wide option.
Ok but I get confused on the this point : does it mean once network-wide option is set this option is the same in all sites? Or is it overriden per each site?
I mean if I do this :
update_site_option('option_group', 'default_options());// default_options() returns an array of default options
Where will it save datas? And will each site get its own values for options after?
It's quite unclear for me any hint will be cool.
