If you know that you will want to apply a filter to all of your post titles in WordPress, such as forcing uppercase, lowercase, or title capitalization, you can use a filter to do so. The filter below will force a title to lowercase as the post is saved:
- function
- ucc_post_title_filter( $data ) {
- $title = $data['post_title'];
- $data['post_title'] = $title;
- return( $data );
- }
- add_filter( 'wp_insert_post_data' , 'ucc_post_title_filter' );
- endif;
On line 6, strtolower() can be exchanged for any text-transforming function.
