Add taxonomy combinations to YOAST sitemap - php

Question

Used rewrite rules to achieve the current url setup but I need these combinations also added to the sitemap. 'collection' is just a product attribute with the taxonomy of pa_collection
Current URL Setup
https://*****.com/collection/%COLLECTION-TERM%/product-tag/%PRODUCT-TAG-TERM%
<?php
/**
* Create a new custom yoast seo sitemap

add_filter( 'wpseo_sitemap_index', 'ex_add_sitemap_custom_items' );
add_action( 'init', 'init_wpseo_do_sitemap_actions' );
// Add custom index
function ex_add_sitemap_custom_items(){
global $wpseo_sitemaps;
$date = $wpseo_sitemaps->get_last_modified('CUSTOM_POST_TYPE');
$smp ='';
$smp .= '<sitemap>' . "\n";
$smp .= '<loc>' . site_url() .'/CUSTOM_KEY-sitemap.xml</loc>' . "\n";

return $smp;

add_action( "wpseo_do_sitemap_CUSTOM_KEY", 'ex_generate_origin_combo_sitemap');

// Clear the post_meta and the term cache for the post, as we no longer need it now.

}
// Grab last modified date
$sql = $wpdb->prepare(" SELECT MAX(p.post_modified_gmt) AS lastmod
FROM $wpdb->posts AS p
WHERE post_status IN ('publish') AND post_type = %s ", $post_type );
$mod = $wpdb->get_var( $sql );
// Generate terms URLs
$practitioner_terms = get_terms( 'pa_collection', 'orderby=count&hide_empty=0' );
$practitioner_termss = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );
if( !empty( $practitioner_terms ) ){
$pri = 1;
$chf = 'weekly';
foreach ($practitioner_terms as $key => $term ){
$url = array();
$url['loc'] = site_url().'/collection/'.$term->slug.'/product-tag/';
$url['pri'] = $pri;
$url['mod'] = $mod;
$url['chf'] = $chf;

}
foreach ($practitioner_termss as $key => $term ){
$url = array();

$url['pri'] = $pri;
$url['mod'] = $mod;
$url['chf'] = $chf;
$output .= $wpseo_sitemaps->sitemap_url( $url );
}
}
This is the section is where I need to combine the taxonomies. So far I have all the terms for both taxonomies on the same page but I need to have them combined to create all the possible combinations.
$practitioner_terms = get_terms( 'pa_collection', 'orderby=count&hide_empty=0' );
$practitioner_termss = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );
if( !empty( $practitioner_terms ) ){
$pri = 1;
$chf = 'weekly';
foreach ($practitioner_terms as $key => $term ){
$url = array();
$url['loc'] =site_url().'/collection/'.$term>slug.'/product-tag/';
$url['pri'] = $pri;
$url['mod'] = $mod;
$url['chf'] = $chf;
$output .= $wpseo_sitemaps->sitemap_url( $url );
}
foreach ($practitioner_termss as $key => $term ){
$url = array();
$url['loc'] = site_url().'/product-tag/'.$term->slug;
$url['pri'] = $pri;
$url['mod'] = $mod;
$url['chf'] = $chf;
$output .= $wpseo_sitemaps->sitemap_url( $url );
}
}

Figured out a solution that works, could possibly be useful to others...
$practitioner_terms = get_terms( 'pa_collection', 'orderby=count&hide_empty=0' );
$practitioner_termss = get_terms( 'product_tag', 'orderby=count&hide_empty=0' );
if( !empty( $practitioner_terms ) ){
$pri = 1;
$chf = 'weekly';
foreach ($practitioner_terms as $key => $term ){
foreach ($practitioner_termss as $key => $terms ){
$url = array();
$url['loc'] = site_url().'/collection/'.$term->slug.'/product-tag/'.$terms->slug;
$url['pri'] = $pri;
$url['mod'] = $mod;
$url['chf'] = $chf;
$output .= $wpseo_sitemaps->sitemap_url( $url );
}
}
}
