Question

As the title suggests, I have a span that is automatically generated by SimpleCart (Javascript Cart) – I want to use that span with a different checkout gateway then they support. Therefore, I need to take some of their tags and “echo” them into PHP variables.

For example:

<input type="hidden" name="fltAmount" value="###">

<span class="simpleCart_finalTotal">

The SPAN needs to be able to be passed into the INPUT so I can send it off to Paypoint.net

Answer 1

Your code should look something like this:

<input type="hidden" name="fltAmount" value="" id="fltAmount">
<span class="simpleCart_finalTotal" id="finalTotal">

And in the form, you will call a function (onsubmit) that looks like:

<form onSubmit="calledOnSubmit(event)" ... > ... </form>

An the function:

function calledOnSubmit(event) {
  var inputAmount = document.getElementById('fltAmount');
  var spanTag = document.getElementById('finalTotal');

  inputAmount.value = spanTag.innerHTML

}
