In this integration method we will integrate J2Store offline sales.

Open payment_offline.php file at plugins/j2store/payment_offline, find function _postPayment() and locate this line

if ($orderpayment->save()) {

Add following code just above line and save.

$vars->order_id = $orderpayment->order_id;

$vars->total_cost = $orderpayment->order_subtotal;

Now open postpayment.php file at plugins/j2store/payment_offline/payment_offline/tmpl and add this code to the end of the file:

<script async>

function hideIF() {    

    document.getElementById('IF').style.visibility = '';


function getSaleInfo() {

    document.getElementById('st_code').style.visibility = 'hidden';

    document.getElementById('st_code').innerHTML='<iframe src="YOUR-OSI-URL/sales/salejs/amount:<?php echo $vars->total_cost; ?>/transaction:<?php echo $vars->order_id; ?>/firstname:FIRST_NAME/lastname:LAST_NAME" alt="" id=IF width=50 height=50 border="0" frameborder="0" onload="hideIF()">';


window.onload = getSaleInfo;


<div id="st_code"></div>

Change ‘YOUR-OSI-URL’ with your OSI URL.
