public function i18n_string_textgroup_default::multiple_translation_search in Internationalization 7

Search multiple translations with key combinations.

Each $context field may be a single value, an array of values or '*'. Example: array('term', array(1,2), '*') This will be mapped into the following conditions (provided language code is 'es') array('type' => 'term', 'objectid' => array(1,2), 'property' => '*', 'language' => 'es') And will result in these combinations to search for array('type' => 'term', 'objectid' => 1, 'property' => '*', 'language' => 'es') array('type' => 'term', 'objectid' => 2, 'property' => '*', 'language' => 'es')

Parameters

$context array: Array with String context conditions.

Return value

Array of translation objects indexed by context.
