Get all Term data from database by Term ID.
The usage of the get_term function is to apply filters to a term object. It is possible to get a term object from the database before applying the filters.
$term ID must be part of $taxonomy, to get from the database. Failure, might be able to be captured by the hooks. Failure would be the same value as $wpdb returns for the get_row method.
There are two hooks,>‘get_term’ hook – Takes two parameters the term Object and the taxonomy name. Must return term object. Used in get_term() as a catch-all filter for every $term.
‘get_$taxonomy’ hook – Takes two parameters the term Object and the taxonomy name. Must return term object. $taxonomy will be the taxonomy name, so for example, if ‘category’, it would be ‘get_category’ as the filter name. Useful for custom taxonomies or plugging into default taxonomies.
