Get translated taxonomy terms with Entity Translation

Question

I'm using Entity Translation for Taxonomy Terms.

I've a Cities Vocabulary and I need to get translated names of some 1600 cities.

Using taxonomy_get_tree without arguments returns the term names in English. However if I pass the last parameter $load_entities= TRUE then it currectly returns $term->name as translated one.

But it seems fully loading 1600 terms by setting $load_entities can slown down the site performance heavily as mentioned in the api page.

Is there any faster way to do it?

I'm thinking of caching the results in a temp file. Or can use some query as in When using Entity Translation and the Title module, how can I get the translated term from the term ID programmatically? to fetch it myself.

Answer 1

You are using Entity Translation, so keep in mind there can't be any translated term load because you're translating fields not whole term. Term will load by

$term = taxonomy_term_load($tid);

use in devel mode or by dpm see the $term object. There you'll see structure

$term->name_field['en'][0]['value'] 

You can fetch it this way or by field_get_items() for en language.

$name = field_get_items('taxonomy_term', $term, 'name_field', 'en');

AND

$term->name_field['fr'][0]['value']

You can fetch it this way or by field_get_items() for fr language.

$name = field_get_items('taxonomy_term', $term, 'name_field', 'fr');

This is how you can get the data per language
