get_term()

get_term() — Gets 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 $wpdb returns for the get_row method. There are two hooks, one is specifically for each term, named ‘get_term’, and the second is for the taxonomy name, ‘term_$taxonomy’.

Inputs: $term (int|WP_Term|object): If integer, term data will be fetched from the database, or from the cache if available. If stdClass object (as in the results of a database query), will apply filters and return a WP_Term object with the $term data. If WP_Term, will return $term. $taxonomy (string): Optional. Taxonomy name that $term is part of. $output (string): Optional. The required return type. One of OBJECT, ARRAY_A, or ARRAY_N, which correspond to a WP_Term object, an associative array, or a numeric array, respectively. Default OBJECT. $filter (string): Optional. How to sanitize term fields. Default ‘raw’.

Returns WP_Term|array|WP_Error|null: WP_Term instance (or array) on success, depending on the $output value. WP_Error if $taxonomy does not exist. Null for miscellaneous failure.
