I'm using a plugin called "Multi-Column Tag Map" that lets you display all tags that were used and arrange them in a alphabetical order. This plugin works fine in a regular post-type but It's not working on a custom post-type that I created. I created a new post-type called 'books' and has an additional taxonomy(Tags) of 'Writers' and 'Tags'.
I followed this to create my custom post type: http://justintadlock.com/archives/2010/04/29/custom-post-types-in-wordpress
How do i customize this to fetch my tags from my custom post-type?
This is the plugin code:
-- code removed, updated version below.
Update:
The purpose of this plugin on my site is to list all tags that we're used for the books. So user can just go to that page and browse articles/books by tags that were used.
I also tried Helgatheviking solution, It's similar to the plugin (Multi-Column Tag Map). But I'll just be sticking on customizing the plugin for the meantime as the plugin already provide some formatting. I just need to deal with get_terms().
My current problem is when using Helgatheviking or the Multi-Column Tag Map plugin solution, they're both using get_terms(). and get_terms() only fetch tags that in my posts and not in my custom post-type ('books'). I wanted to fetch tags from my custom post type.
So I did a little search and found this get_terms_by_post_type() by Bainternet. I think this is the solution in fetching tags to a certain post-type get_terms().
So this is what I did (code below), Unfortunately I have an error in my foreach(). It said "Warning: Invalid argument supplied for foreach() in mctagmap.php on line 366"
Additional Details:
post-type i'm targeting = 'the_books'
taxonomy i'm targeting = 'book_tags', 'book_writers' -- This might sound dumb, but I use 'post_tag' below instead of any of those two because I want to target the two of them.
