How to Get Taxonomy ID by Slug in WordPress

To get the taxonomy ID by slug in WordPress, you can use the 'get_term_by()' function. Here is an example code snippet:

$term = get_term_by('slug', 'your-taxonomy-slug', 'your-taxonomy-name');
if ($term) {
    $term_id = $term->term_id;
}

Replace 'your-taxonomy-slug' and 'your-taxonomy-name' with the actual slug and name of your taxonomy. The function will return the term object if a matching term is found, and you can access the taxonomy ID by accessing the 'term_id' property.
