I ran into the same issue after a recent wordpress update. There’s a fairly easy workaround as well as an easy fix for this.
To work around the issue you can assign calculators to products from the calculator properties page (edit the calculator, about 2/3 down the page you can assign it to products).
The issue is in the postPage.js file in /wp-content/plugins/woo-price-calculator/admin/resources/assets/js/
It is using an old version of ajax syntax that uses $ for ajax calls instead of jQuery.
Here’s the revised text of the postPage.js file with the fixes applied, there’s 6 or 8 $ that need to be replaced with jQquery:
/* New JS Code Standard */
jQuery(document).ready(function($){
$(‘.attach_calculator’).on(‘click’, function (e) {
var availableCalculators = JSON.parse($(‘#availableCalculators’).val());
var productId = $(‘#productId’).val();
var simulatorId = $(‘#calculator’).val();
//check if the user has selected a calculator
if (simulatorId == ”) {
//do nothing
}else {
var productsIds = JSON.parse(availableCalculators[simulatorId].products);
attachSimulator(productId, simulatorId, productsIds);
}
});
$(‘.remove_calculator’).on(‘click’, function (e) {
var productIdToRemove = $(‘#productId’).val();
removeSimulator(productIdToRemove);
});
});
/**
* param productId, the id of the product that the user is attaching a calculator
* param simulatorId, the calculator id to be assigned to the product
* param productsIds, the list of products id of the new calculator
*
* return void
* */
function attachSimulator(productId, simulatorId, productsIds) {
requestAjaxCalculatePrice = jQuery.ajax({
method: “POST”,
async: this.asyncAjaxCalculatePrice,
url: jQuery(‘#ajaxUrl’).val()+ “?action=awspricecalculator_ajax_attach_calculator” + “&id=” + productId + “&simulatorid=” + simulatorId ,
dataType: ‘json’,
data: {‘selectedCalculatorProducts’: productsIds},
success: function(result, status, xhrRequest) {
//pass the available calculators to the hidden field
jQuery(‘#availableCalculators’).val(JSON.stringify(result));
//dynamically change the name of the assigned calculator
jQuery(‘#selected_calculator’).text(result[simulatorId].name);
//show the remove calculator button
jQuery(‘.remove_calculator’).show();
},
error: function(xhrRequest, status, errorMessage) {
}
});
}
/**
* param productId, the id of the product that the user removing the calculator
* return void
* */
function removeSimulator(productId) {
requestAjaxCalculatePrice = jQuery.ajax({
method: “POST”,
async: this.asyncAjaxCalculatePrice,
url: jQuery(‘#ajaxUrl’).val()+ “?action=awspricecalculator_ajax_remove_calculator” + “&id=” + productId ,
dataType: ‘json’,
data: {},
success: function(result, status, xhrRequest) {
//remove the calculator name from the selected one place
jQuery(‘#selected_calculator’).text(”);
//hide the remove calculator button
jQuery(‘.remove_calculator’).hide();
//pass the available calculators to the hidden field
jQuery(‘#availableCalculators’).val(JSON.stringify(result));
},
error: function(xhrRequest, status, errorMessage) {
}
});
}
