WordPress Plugin Function

Question

I had a developer write this plugin for me to add functionality to import bulk pricing to products through WP All Import, a while back. He has not been getting back to me regarding this. I had to delete the auto import that we had set up together and I don't remember how to use it to import the bulk pricing with the system he built. Could someone explain what the code indicate that I would do to use it?

<?php
/*
Plugin Name: WP All Import Woo Bulk Pricing Add-On
Description: Import data related to bulk pricing
Version: 1.0    */
//  

function import_pricing_fields($id, $xml_node) {
    // return;
    $post_type = get_post_type($id);

    if($post_type == 'product' || $post_type == 'product_variation' ){
        $xml_node = (array) $xml_node;
        $_product = wc_get_product( $id );
        $number_of_prices = 3;
        if( $_product->is_type( 'simple' ) ) {
            update_post_meta($id,'_regular_price', $xml_node['price']);
            update_post_meta($id,'_price', $xml_node['price']);
            $pricing_array = array();
            for($i=1;$i<$number_of_prices;$i++){
                if(isset($xml_node['qb_'.$i]) && $xml_node['qb_'.$i] != 0){
                    $pricing_array[$i]['min'] = $xml_node['qb_'.$i];
                    if($i > 1){
                        $pricing_array[$i-1]['max'] = $xml_node['qb_'.$i]-1;
                        $pricing_array[$i]['max'] = "*";
                    } else {
                        $pricing_array[$i]['max'] = "*";
                    }
                    $pricing_array[$i]['val'] = $xml_node['price_'.$i];
                }
            }
            $pricing_array = array_values($pricing_array);


            if(!empty($pricing_array)) {

                update_post_meta($id,'_wc_bulk_pricing_custom_ruleset', $pricing_array);
            }
        } else{
            $var_id = wc_get_product_id_by_sku($xml_node['catalog']);
            $variations = $_product->get_children();

            if(!empty($variations)) {
                foreach ($variations as $variation) {
                    $sku = get_post_meta($variation, '_sku', true);

Could someone explain what the code indicate that I would do to use it?

The function import_pricing_fields() is hooked into the 'pmxi_saved_post' action.

http://www.wpallimport.com/documentation/advanced/action-reference/

What this means is that every time you import a post using WP All Import it will also run the function import_pricing_fields().

However this is one check to pass before the majority of the code in this function will run, and that is on line 4 if($post_type == 'product' || $post_type == 'product_variation' ). Which simply means if the post is a product or product_variation continue running this code.

The rest of the code looks like it does what you said, import bulk pricing...
