| /** | |
| * Get posts group by alphabets. | |
| * | |
| * @todo Change the `prefix_` and with your own unique prefix. | |
| * | |
| * @since 1.0.0 | |
| */ | |
| if( ! function_exists( 'prefix_get_posts_group_by_alphabet' ) ) : | |
| function prefix_get_posts_group_by_alphabet() { | |
| $result = array(); | |
| $query_args = array( | |
| 'post_type' => 'post', | |
| // Query performance optimization. | |
| 'no_found_rows' => true, | |
| 'posts_per_page' => 100, | |
| ); | |
| $query = new WP_Query( $query_args ); | |
| if ( $query->posts ) { | |
| foreach ( $query->posts as $key => $post ) { | |
| $first_letter = substr($post->post_title,0,1); | |
| if( ! empty( $first_letter ) ) { | |
| $result[$first_letter][] = array( | |
| 'ID' => $post->ID, | |
| 'title' => $post->post_title, | |
| ); | |
| } | |
| } | |
| } | |
| if( ! empty( $result ) ) { | |
| ksort( $result ); | |
| } | |
| return $result; | |
| } | |
| endif; |
Now we can show the posts with the group by alphabet with a shortcode.
In below code we have created a shortcode prefix_alphabetic_posts to show the result in the post.
NOTE: Below short code is created only for demo purpose. So, Added inline CSS. You need to use wp_enqueue_scripts to enqueue your scripts.
