* The 'get_terms_fields' filter passes the fields for the SELECT query

*
- * The list of arguments that $args can contain, which will overwrite the defaults:
- *
- * orderby - Default is 'name'. Can be name, count, term_group, slug or nothing
- * (will use term_id), Passing a custom value other than these will cause it to
- * order based on the custom value.
- *
- * order - Default is ASC. Can use DESC.
- *
- * hide_empty - Default is true. Will not return empty terms, which means
- * terms whose count is 0 according to the given taxonomy.
- *
- * exclude - Default is an empty array. An array, comma- or space-delimited string
- * of term ids to exclude from the return array. If 'include' is non-empty,
- * 'exclude' is ignored.
- *
- * exclude_tree - Default is an empty array. An array, comma- or space-delimited
- * string of term ids to exclude from the return array, along with all of their
- * descendant terms according to the primary taxonomy. If 'include' is non-empty,
- * 'exclude_tree' is ignored.
- *
- * include - Default is an empty array. An array, comma- or space-delimited string
- * of term ids to include in the return array.
- *
- * number - The maximum number of terms to return. Default is to return them all.
- *
- * offset - The number by which to offset the terms query.
- *
- * fields - Default is 'all', which returns an array of term objects.
- * If 'fields' is 'ids' or 'names', returns an array of
- * integers or strings, respectively.
- *
- * slug - Returns terms whose "slug" matches this value. Default is empty string.
- *
- * hierarchical - Whether to include terms that have non-empty descendants
- * (even if 'hide_empty' is set to true).
- *
- * search - Returned terms' names will contain the value of 'search',
- * case-insensitive. Default is an empty string.
- *
- * name__like - Returned terms' names will begin with the value of 'name__like',
- * case-insensitive. Default is empty string.
- *
- * The argument 'pad_counts', if set to true will include the quantity of a term's
- * children in the quantity of each term's "count" object variable.
- *
- * The 'get' argument, if set to 'all' instead of its default empty string,
- * returns terms regardless of ancestry or whether the terms are empty.
- *
- * The 'child_of' argument, when used, should be set to the integer of a term ID. Its default
- * is 0. If set to a non-zero value, all returned terms will be descendants
- * of that term according to the given taxonomy. Hence 'child_of' is set to 0
- * if more than one taxonomy is passed in $taxonomies, because multiple taxonomies
- * make term ancestry ambiguous.
- *
- * The 'parent' argument, when used, should be set to the integer of a term ID. Its default is
- * the empty string '', which has a different meaning from the integer 0.
- * If set to an integer value, all returned terms will have as an immediate
- * ancestor the term whose ID is specified by that integer according to the given taxonomy.
- * The 'parent' argument is different from 'child_of' in that a term X is considered a 'parent'
- * of term Y only if term X is the father of term Y, not its grandfather or great-grandfather, etc.
- *
- * The 'cache_domain' argument enables a unique cache key to be produced when this query is stored
- * in object cache. For instance, if you are using one of this function's filters to modify the
- * query (such as 'terms_clauses'), setting 'cache_domain' to a unique value will not overwrite
- * the cache for similar queries. Default value is 'core'.

+ * 1. The term is added to the term table, then related to the taxonomy.

+ * 4. The term cache is cleaned.

*
- * 'description'. There is no default. If exists, will be added to the database
- * along with the term. Expected to be a string.
- *
- * 'parent'. Expected to be numeric and default is 0 (zero). Will assign value
- * of 'parent' to the term.
- *
- * 'slug'. Expected to be a string. There is no default.
+ * If the taxonomy is hierarchical, and the 'parent' argument is not empty,
