Export Categories and Tags

This code snippet is used to export WordPress categories and tags into a CSV file and adds a page in the WordPress admin area to run this export function. It also enqueues a JavaScript file that could add additional functionality to the export page.

PHP

function export_tags_and_categories() {
    $terms = get_terms( array( 'category', 'post_tag' ), array( 'hide_empty' => false ) );
    $output = fopen( 'php://output', 'w' );
    fputcsv( $output, array( 'Term ID', 'Name', 'Slug', 'Description', 'Taxonomy' ) );
    foreach ( $terms as $term ) {
        fputcsv( $output, array(
            $term->term_id,
            $term->name,
            $term->slug,
            $term->description,
            $term->taxonomy
        ) );
    }
    fclose( $output );
}
