I needed to populate a Custom Taxonomy "Days" with the days of the week..I did not want the client to have to mess with creating days, or get in there and delete days or misspell days. Following the above advice I came up with this, but I am wondering if there is a more concise way of coding it:
/*************************************** ...Create a Custom Taxonomy for days ******************************/
add_action( 'init', 'build_taxonomies', 0 );
function build_taxonomies() {
register_taxonomy(
'days',
'schedule',
array( 'hierarchical' => true,
'label' => 'Days',
'query_var' => true,
'show_ui' => false, //removes the menus from admin menu and edit panel
'rewrite' => true ) );
/*---------------------------------------Check to see if the days are created..if not, create them----*/
$parent_term = term_exists( 'days', 'days' ); // array is returned if taxonomy is given
$parent_term_id = $parent_term['term_id']; // get numeric term id
wp_insert_term(//this should probably be an array, but I kept getting errors..
'Monday', // the term
'days', // the taxonomy
array(
'slug' => 'monday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Tuesday', // the term
'days', // the taxonomy
array(
'slug' => 'tuesday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Wednesday', // the term
'days', // the taxonomy
array(
'slug' => 'wednesday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Thursday', // the term
'days', // the taxonomy
array(
'slug' => 'thursday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Friday', // the term
'days', // the taxonomy
array(
'slug' => 'friday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Saturday', // the term
'days', // the taxonomy
array(
'slug' => 'saturday',
'parent'=> $parent_term_id ));
wp_insert_term(
'Sunday', // the term
'days', // the taxonomy
array(
'slug' => 'sunday',
'parent'=> $parent_term_id ));
}
/************ now I add my own meta box for days to get rid of extra controls *************/
add_action('admin_menu', 'add_custom_categories_box');
function add_custom_categories_box() {
add_meta_box('myrelateddiv', 'Days*', 'ilc_post_related_meta_box', 'schedule', 'normal', 'low', array( 'taxonomy' => 'days' ));
}
function ilc_post_related_meta_box( $post, $box ) {
$defaults = array('taxonomy' => 'related');
if ( !isset($box['args']) || !is_array($box['args']) )
$args = array();
else
$args = $box['args'];
extract( wp_parse_args($args, $defaults), EXTR_SKIP );
$tax = get_taxonomy($taxonomy);
?>
<ul id="<?php echo $taxonomy; ?>checklist" class="list:<?php echo $taxonomy?> categorychecklist form-no-clear">
<?php
wp_terms_checklist($post->ID, array( 'taxonomy' => $taxonomy, 'popular_cats' => $popular_ids, 'checked_ontop' => FALSE ) )
?>
</ul>
