Surprisingly, WordPress does not provide a mechanism for sorting taxonomies by a custom defined order. Taxonomies can only be sorted by name or id. Custom Taxonomy Sort allows the average user a mechanism to define and display terms in a specified order. After installing Custom Taxonomy Sort, each taxonomy term will have the ability to have a “tax-order” value associated with it. This order is specified by doing the following:
- Go to any taxonomy add or edit screen (e.g., wp-admin/edit-tags.php?taxonomy=category)
- Fill in a numeric value for the “Order” field. By default, the order will be ascending, meaning it will sort from low to high (e.g., 1, 2, 3). These values can be added on the Add Taxonomy screen, the Edit Taxonomy screen, or through the Quick Edit panel.
- Observe all of your terms automagically being sorted in the order you specified
Custom Taxonomy Sort automatically applies the sort order to all instances in which the terms are displayed. All you need to do is define that order.
In addition to automatically sorting the terms, Custom Taxonomy Sort allows developers to override the automatic sort to offer finer control over how terms are displayed in different parts of WordPress. Manual mode can be started by changing “Automatic Sort” to “Off” in the Custom Taxonomy Sort Settings page (wp-admin/options-general.php?page=custom-taxonomy-sort-settings). Once “Automatic Sort” is switched to “Off”, the terms will no longer be sorted automatically by the custom order. Instead, the custom sort order can be envoked with a new parameter for the “orderby” argument. Custom Taxonomy Sort allows you to use the following argument to access a custom sorted list of terms using “get_terms”
<?php get_terms('orderby=custom_sort'); ?>
Voila! Now, your terms will only be sorted by the specified order in the places that you want it sorted in this order. All other instances of displaying terms will revert to WordPress’ default of sorting the terms by name. Additionally, you can specifically have the terms sort in ascending (‘ASC’; default; e.g., 1, 2, 3) or descending (‘DESC’; e.g., 3, 2, 1) order by adding the “order” argument.
<?php get_terms('orderby=custom_sort&order=ASC'); ?> <?php get_terms('orderby=custom_sort&order=DESC'); ?>

- After installation, what do I need to do?
After installing the plugin, all taxonomies will be automatically sorted by your custom order; however, you need to vist the individual taxonomy term edit pages to enter the order of the terms.
- What is “Automatic Sort”
“Automatic Sort” has two states: “On” (default) and “Off”. When “Autmatic Sort” is set to “On”, every call to “get_terms” will be sorted by the custom sort order. In this mode, you do not have to manually add parameters to the “get_terms” function calls to have the terms sorted by the custom sort order. You can think of the “On” state as allowing the plugin to do everything for you; all you need to do is tell it in what order you want the terms to be sorted. On the other hand, if you set “Automatic Sort” to “Off”, you need to manually send parameters to the “get_terms” functions in order for the terms to be sorted by the custom sort order. The “Off” mode is best for developers who want absolute control over every time the terms are sorted and displayed.
- What is “Sort Order”
“Sort Order” is the order in which the terms are sorted. “Ascending” will sort the terms from lowest to highest value (e.g., 1, 2, 3). “Descending” will sort the terms from highest to lowest value (e.g., 3, 2, 1).
