Changeset 28733 for trunk/src/wp-includes/taxonomy.php

Timestamp:

06/11/2014 02:27:36 AM (10 years ago)

Message:

In wp_insert_term(), when no slug is provided, check for an existing term by name. If it exists, use that slug instead of calling sanitize_title( $name ).

Prevents creating an endless number of terms like A+ or $$$$ in any given taxonomy.

Props wonderboymusic, SergeyBiryukov, aaroncampbell.
Fixes #17689.
