IIS 7 Rewrite with parent categories

Finally figured out the answer. It is a mix of multiple different solutions I have found online but here it is!

First step is to add this to your functions.php

add_rewrite_rule(
    'products/([^/]+)/([^/]+)/?',       
    'index.php?pmfg_product_categories=$matches[1]&products=$matches[2]',      
    'top'
);

Secondly you will need this in your web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules><rule name="WordPress Rule" stopProcessing="true"><match url=".*"/><conditions><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/></conditions><action type="Rewrite" url="index.php?page_id={R:0}"/></rule>
<rule name="wordpress" patternSyntax="Wildcard">
<match url="*"/>
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true"/>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true"/>
</conditions>
<action type="Rewrite" url="index.php"/>
</rule></rules>
</rewrite>
</system.webServer>
</configuration>


Lastly here is how I have my custom post type and taxanomy setup. Replace “yourid” with whatever you want to make sure you dont have any issues with other plugins.

// Register Custom Post Type
function yourid_product_tax_type(){
    $labels = array(
        'name'                       => _x( 'Product Categories', 'Taxonomy General Name', 'text_domain' ),
        'singular_name'              => _x( 'Product Category', 'Taxonomy Singular Name', 'text_domain' ),
        'menu_name'                  => __( 'Product Categories', 'text_domain' ),
        'all_items'                  => __( 'All Product Categories', 'text_domain' ),
        'parent_item'                => __( 'Parent Category', 'text_domain' ),

    );
    $args = array(

    register_taxonomy( 'yourid_product_categories', array(), $args );

add_action( 'init', 'yourid_product_tax_type', 0 );

function yourid_post_type() {
