Thanks again Milo and George for your help. I finally decided to use custom taxonomies. Here was my procedure.
// 1. Create the two taxonomies I need.
function create_playground_taxonomy() {
register_taxonomy( 'cartoon-playground', 'post', array (
'rewrite' => array( 'slug' => 'Cartoon-Playground'),
'hierarchical' => false,
'labels' => array(
'name' => _x( 'Cartoon Playground Tags', 'taxonomy general name' ),
'all_items' => __( 'All Playground Cartoons' ),
'singular_name' => _x( 'Cartoon Playground Tag', 'taxonomy singular name' )
)
)
);
}
add_action( 'init', 'create_playground_taxonomy' );
function create_treasury_taxonomy() {
register_taxonomy( 'cartoon-treasury', 'post', array (
'rewrite' => array( 'slug' => 'Cartoon-Treasury' ),
'hierarchical' => false,
'labels' => array(
'name' => _x( 'Cartoon Treasury Tags', 'taxonomy general name' ),
'all_items' => __( 'All Treasury Cartoons' ),
'singular_name' => _x( 'Cartoon Treasury Tag', 'taxonomy singular name' )
)
)
);
}
add_action( 'init', 'create_treasury_taxonomy' );
// 2. Copies terms from post_tag to the two new taxonomies.
// After updating functions.php, refresh any non-admin page
// on your site——that's what activates the function.
function replicateTaxonomyTerms() {
$terms = get_terms( 'post_tag' );
$count = count($terms);
if ( $count > 0 ){
foreach ( $terms as $term ) {
wp_insert_term( $term->name, 'cartoon-treasury', array( 'slug' => $term->slug) );
wp_insert_term( $term->name, 'cartoon-playground', array( 'slug' => $term->slug) );
}
}
}
add_action('init', 'replicateTaxonomyTerms');
// 3. Identifies post_tag terms that are associated with one post
// and associates that post with terms in the other taxonomies.
//
// I needed this code because I invented these taxonomies AFTER
// the posts were imported. If you define the taxonomies before
// importing, you should work with your import functions instead.
// This code was used only to initially update all my posts. Below
// is a different function that I use update the posts every day.
//
// So for example post1 is originally associated with the post_tag
// term 'green-bean.' After running this code, post1 will also be
// associated with the treasury taxonomy term 'green-bean.'
//
// Refresh a non-admin page once this code is in functions.php.
// Increment the offset by 500 (or whatever your server can handle)
// until you modify all your posts.
//
// When you've updated all your posts, comment-out or delete the code.
function updatePostsTerms() {
global $post;
$args = array(
'posts_per_page' => 500,
'offset' => 0,
'post_type' => 'post',
'cat' => 953
);
$the_query = get_posts( $args ); // Should grab ALL posts
if ($the_query) {
foreach ($the_query as $post) {
$post_id = $post->ID;
$args = array( 'orderby' => 'name', 'order' => 'ASC', 'fields' => 'names' );
$tags = wp_get_post_tags( $post_id, $args ); // Gets existing tags. The array is a list af arguments used to grab only the term IDs and order them.
$new_terms = implode(', ', $tags);
$append = false;
wp_set_post_terms( $post_id, $new_terms, 'cartoon-treasury', $append );
wp_set_post_terms( $post_id, $new_terms, 'cartoon-playground', $append );
}
}
wp_reset_query();
}
add_action('wp_head', 'updatePostsTerms'); */
// Duplicates post_tag terms when post is saved. So for example user
// inputs 'chocolate' as a new tag term. When saved, 'chocolate' is
// saved to the other taxonomies as well.
//
// To maintain accurate tag clouds, I need some posts to NOT be
// associated with all taxonomies, and so I check the posts' category
// to see if it's one that should have the post_tag term duplicated.
//
// Keep this code in functions.php.
function duplicateTerms( ){
$post_id = $_POST['post_ID'];
$new_terms = $_POST['adv-tags-input'];
$categories = $_POST['post_category'];
$new_terms = explode(',', $new_terms);
foreach ($new_terms as $term){
wp_insert_term( $term, 'cartoon-treasury', array( 'slug' => $term) );
wp_insert_term( $term, 'cartoon-playground', array( 'slug' => $term) );
}
$append = false;
foreach ( $categories as $category ) {
if ( $category == 953 ) {
wp_set_post_terms( $post_id, $new_terms, 'cartoon-treasury', $append );
}
}
foreach ( $categories as $category ) {
if ( $category == 4074 ) {
wp_set_post_terms( $post_id, $new_terms, 'cartoon-playground', $append );
}
}
}
add_action( 'save_post', 'duplicateTerms' );
// With these taxonomies, I have control over tag clouds and template pages.
// When looking at cartoons via the slider, a user can click a tag from
// the tag cloud and be directed to another slider page. These slider pages
// have URLs that look like this: site.com/taxonomy-name/term , and I can
// modify these pages by modifying the taxonomy's template.
//
// When looking at cartoons on the blog, a user can click a tag from the tag
// cloud and be directed to posts in blog-format. URLs look like this: site.com
// /blog/term.
//
// I'm still running into some problems with this setup, by most things
// are working. :)
Thanks everyone for all your help.
