Hi all,<\/p>\n

I used to use the following method to do multi-site under wp 2.9 without using any plugin.<\/p>\n

I just replace:<\/p>\n

$table_prefix = 'wp_';<\/code><\/p>\n

with:<\/p>\n

$table_prefix = ereg_replace('^(www\\.)', '', $_SERVER['HTTP_HOST']);\n$table_prefix = ereg_replace('\\.', '', $table_prefix);\n$table_prefix = ereg_replace('\\-', '', $table_prefix);\n$table_prefix = $table_prefix . '_';<\/code><\/pre>\n
I think this method still work under wp 3 (I haven’t test it).<\/p>\n
I build a test site and tried the multi-site and domain mapping plugin. It seems it’s more complicated than the above method. So I just wonder why I need to follow the “official” way, is there any advantage of doing so? Any comments? Thanks.<\/p>\n","protected":false},"template":"","class_list":["post-1648665","topic","type-topic","status-closed","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/1648665","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/1648665\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=1648665"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
