How to make woocommerce-pdf-invoice works with WOOCS

The plugin woocommerce-pdf-invoice allows you print invoices in pdf format. But one thing - no filters and actions to make it works fine with the WOOCS. So I decided investigate this question and resilve this tasks by hacking woocommerce-pdf-invoice plugin code. You can do the same if you are want use woocommerce-pdf-invoice with WOOCS.

Go to plugins/woocommerce-pdf-invoice/includes/woo-pdf-invoice.class.php
We need make changes in 8 places in file woo-pdf-invoice.class.php

Finf function total and change code on next:

public function total() {
            if(class_exists('WOOCS')) {
                return (double) WOOCS::normalize_order_data($this->orderData->id, $this->orderData->order_total);
            } else {
                return (double) $this->orderData->order_total;
            }
        }

You will get something like this:

Then find function row_total and insert next code there as on screen:

if(class_exists('WOOCS')) {
                $line_subtotal = WOOCS::normalize_order_data($this->orderData->id, $line_subtotal);
            }

Then find function item_price and replace code by this as on screen:

if((((double) $price) * (int) $item['qty']) == (double) $this->row_total($item, $this->orderData)) {
                if(class_exists('WOOCS')) {
                    return WOOCS::normalize_order_data($this->orderData->id, $price);
                } else {
                    return $price;
                }
            } else {
                if(class_exists('WOOCS')) {
                    return WOOCS::normalize_order_data($this->orderData->id, $price);
                } else {
                    return $price;
                }
            }

Then find function get_totals and replace next code as on screen:

if(class_exists('WOOCS')) {
                $totals['subtotal'] = array(
                    'name'=>$this->invoiceOptions['woo_pdf_title_subtotal'],
                    'value'=>(double) WOOCS::normalize_order_data($this->orderData->id, $subtotal),
                );
            } else {
                $totals['subtotal'] = array(
                    'name'=>$this->invoiceOptions['woo_pdf_title_subtotal'],
                    'value'=>(double) $subtotal,
                );
            }

In the same function find string //Display taxes below total only if subtotal is displayed including taxes and insert next code:

if(class_exists('WOOCS')) {
                $totals['total'] = array(
                    'name'=>$this->invoiceOptions['woo_pdf_title_total'],
                    'value'=>(double) WOOCS::normalize_order_data($this->orderData->id, $this->orderData->order_total),
                );
            } else {
                $totals['total'] = array(
                    'name'=>$this->invoiceOptions['woo_pdf_title_total'],
                    'value'=>(double) $this->orderData->order_total,
                );
            }

Find function render_left_block and replace next code:

if(class_exists('WOOCS')) {
                $blocks = array(
                    'amount_in_words'=>array(
                        'title'=>$this->invoiceOptions['woo_pdf_title_amount_in_words'],
                        'text'=>$this->get_amount_in_words((double)WOOCS::normalize_order_data($this->orderData->id, $this->orderData->order_total), $this->invoiceOptions),
                    ),
                );
            } else {
                $blocks = array(
                    'amount_in_words'=>array(
                        'title'=>$this->invoiceOptions['woo_pdf_title_amount_in_words'],
                        'text'=>$this->get_amount_in_words((double) $this->orderData->order_total, $this->invoiceOptions),
                    ),
                );
            }

Go to function amount_in_words and replace next code:

 if(class_exists('WOOCS')) {
                $currency = get_post_meta($this->orderData->id, '_woocs_order_currency', TRUE);
                if(!$self) {
                    $string .= ' ';
                    $string .= $currency;
                }
             }else{
                if(!$self) {
                    $string .= ' ';
                    $string .= _n('dollar', 'dollars', $number, 'woo_pdf');
                }
             }

That is all!
