I am battling having a problem I am unable too solve. I have spent lots of hourse in codex documentation with no luck. I have produced a custom publish type known as "Items". Items is going to be obtainable in many language. Items permalink is one thing like: mysite.com/items/product-title Things I need rather is one thing such as this: mysite.com/language/items/product-title. What I have to produce the permalink? Have I to include some fancy rule with Wordpress_Rewrite? Could it be possibile to possess custom publish type as page child's? I do not actually need custom taxonomy if you know a much better solution fell liberated to write. Thank you for any suggestion.

You'll need a wordpress plugin for wordpress to beautifully handle multiple languages.

It is best to take a look at wpml.org
