How to query the custom fields by language?
For each post, there is a custom field name “Function”, the key/value pair is like this:
Key : Functions Value : <!--en-->Nourishing Yin and invigorating the vital essence of kidneys.<!--:--><!--tw-->滋陰補腎。<!--:-->
The problem is if I simply use get_post_meta , it return string of both language, how can I get the value based on the language?
I am using qTranslate right now, Thanks.
