Categories by default only show posts, as do tags. This limitation is not enforced on custom taxonomies, and it can be overriden via a filter. If you place this into your functions.php, then posts of type help-line will be shown in the listings. // before we grab the posts in a query add_filter(‘pre_get_posts’, ‘wpse49960_query_post_type’); function … Read more
Yes you can, WP has a build in function to attach a custom taxonomy to a (custom) posttype: http://codex.wordpress.org/Function_Reference/register_taxonomy
You can remove meta boxes with the remove_meta_box function: function wpse50430_remove_meta_boxes() { // make sure we’re on an admin screen and `post` is set if( !is_admin() && !isset( $_GET[‘post’] ) ) return; if( $_GET[‘post’] == 99 ): // editing page ID 99 remove_meta_box( ‘pageparentdiv’, ‘page’, ‘normal’ ); endif; } add_action( ‘admin_menu’, ‘wpse50430_remove_meta_boxes’ ); To remove … Read more
Change $single back to false, e.g.: <?php $name_text = get_post_meta( 65, ‘name_text’ ); ?> Why? If set to true then the function will return a single result, as a string. If false, or not set, then the function returns an array of the custom fields. This is not intuitive. For example, if you fetch a … Read more
empty will only take variables passed by reference. so empty(some_function()) will never work. See the php docs for more information. <?php if (get_custom_field_value(“signature”,””)) : ?> — <?php the_category( ‘<span>/</span>’ ); ?> <?php endif; ?> You’re better off just checking for the boolean, like above. The get_custom_field_value function already takes care of making sure you get … Read more
I think you’ve way over-complicated things. Assuming private is a checkbox, just check for it being set, and act accordingly. With form $_POST data, a checkbox will send its value if checked, and will send nothing if not checked: if ( isset( $_POST[‘private’] ) ) { update_comment_meta( $comment_id, ‘private’, ‘private’ ); } else { delete_comment_meta( … Read more
Your first line reads: $key = “key”; And your last line reads: update_post_meta( $post_id, $key, $data ); So, for all I can see here, if you change it to: $key = “item_color”; You should be good to go.
You can call get_post_meta inside of a conditional statement and display data depending on the field value (empty or set), check the sample loop in the Codex
I’ve had a brief look at the plug-in, it offers no hooks to do this, but you could use posts_clauses hook to alter the query. That said my SQL is not good enough to say how (if it’s possible) to convert the ‘human readable’ value to a decimal, prior to sorting. Even if it could, … Read more
If you still use the plugin WTI Likes you can get the values direkt from the table that the plugin creates instead of saving values to the post meta. Add this code where you want your list. Now it prints all post that have been liked. From most to least. <?php global $wpdb; $query = … Read more
