Simple Jquery Calculation & Event Trigger WordPress



I'm modifying a 'booking form' for the events manager wordpress plugin and would like a bit of help with the Jquery.

There's 2 parts to this question:

1) I need to display the total based upon a select field and the price of a ticket, so if a ticket is €50 and there's 4 selected, it will display €200. I've found this code (below) which sort of works but it's not calculating properly, it needs to get the value from the select field properly (see below link as well). I think it's just a case of changing the ".data('price')" part.


$(document).ready(function () {
var price = parseFloat($('.price').data('base-price'));

$('.em-ticket-select').each(function(i, el) {
price += parseFloat($('option:selected', el).data('price'));

$('.price span').text(price.toFixed(2));


<p class="price" data-base-price="50">&pound;<span>50.00</span></p>

2) Also on this page, if you don't enter any details you'll get an error message, which displays at the top - using Jquery I need to either move this warning to the bottom, or scroll the user up to the error message upon reloading with an error.

Please help :)

Replace the all the $ symbols with jQuery

like this

jQuery(document).ready(function () {
var price = parseFloat(jQuery('.price').data('base-price'));
jQuery('.em-ticket-select').each(function(i, el) {
price += parseFloat(jQuery('option:selected', el).data('price'));
jQuery('.price span').text(price.toFixed(2));

How do I change this bit: data('price') to take the number from the dropdown menu?

Hello Meakin I have PM ed you and also there is another code in your script


which you need to change the $ as jQuery. Also it is not properly closed
it should close like });
