Get all Term data from database by Term ID. To retrieve term data by name, slug or ID, use get_term_by() instead
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'. Both hooks gets the term object, and the taxonomy name as parameters. Both hooks are expected to return a Term object.
'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.
<?php get_term( $term, $taxonomy, $output, $filter ) ?>
Get Term offers some handy information, but unfortunately lacks a link value.
$term = get_term( $term_id, $taxonomy );
Gives you term slug: e.g.: term-slug-example
$slug = $term->slug;
Gives you term name: e.g. Term Name Example
$name = $term->name;
Gives you term description: e.g. This is my new cool custom term.
$desc = $term->description;
