Show user inputs on a summary page - php

Question

I have several quantity boxes next to products so a user can input what quantity they want of a certain product.
The setup uses a step by step process using Jquery with the first step made up of checkboxes, the second made up of quantity inputs (where I need the help!) and the final step shows what has been selected... on submit it all gets emailed to me.
Step 1 with checkboxes is complete (with a lot of help from #Beetroot-Beetroot -Step by step checkbox process with summary of selections). Step 2 is where I need the help, how can I show the user quantity inputs on the summary page?
Here's the HTML:

Here's the Jquery:
jQuery(document).ready(function( $ ) {
//Create nav wrapper
var $nav = $('<div/>').addClass('prev-next');
//Create Prev button, attach click handler and append to nav wrapper
$('<a class="prev" href="#">Back</a>').on('click', function () {
$(this).closest(".step").hide().prev(".step").show();
}).prependTo($nav);
//Create Next button, attach click handler and append to nav wrapper
$('<a class="next" href="#">Next</a>').on('click', function () {
$('.summary_text').html(makeSummary());
var $step = $(this).closest(".step");
if (validate($step)) {
$step.hide().next(".step").show();
}
}).appendTo($nav);
//In one long jQuery chain ...
//* prepend nav to each step div
//* hide all steps except the first
//* convert first 'Back' link and last 'Next' link to spans.
var $steps = $(".step").prepend($nav).hide()
.filter(":first").show().find("a.prev").after('Back').remove().end().end()
.filter(":last").find("a.next").after('').remove().end().end();
//Set step titles
$steps.each(function (i, step) {
$(step).find(".step-title").text('Step ' + (i + 1) + ' of ' + $steps.length);
});
$('a.back-to-product').click(function(){
$(".customise").hide();
$(".entire_product").show();
});
//Unfortunately, hidden form elements are not inlcuded in the submission,
//so all steps must be shown before the form is submitted.
var $submitButton = $("input[name='submit']").on('submit', function () {
$steps.show();
return true;
});
function validate($step) {
//var valid = false;
var valid = true; //for debugging
//Perform validation
switch ($step.index(".step")) { //index-origin is zero
case 0:
//Validate step 1 here
//if valid, set `valid` to true
break;
case 1:
//Validate step 2 here
//if valid, set `valid` to true
break;
case 2:
//No validatation required
break;
}
return valid; //Important - determines behaviour after validate() returns.
}
function makeSummary() {
var summary = [];
$steps.not(":last").each(function (i, step) {
$step = $(step);
summary.push('<p><b>' + $step.data('name') + '</b></p>');
var $ch = $step.find('input[type="checkbox"]:checked');
if (!$ch.length) {
summary.push('<p>No items selected</p><br />');

Answer 1

First, make the quantity[] and product[] fields more readily selectable by hard-coding class="quantity" and class="product" in the HTML.
<input type="text" name="quantity[]" class="quantity" style="width:15px;" value="0">25 cm²<br />
<input type="hidden" name="product[]" class="product" value="Equipment Electrode Set - 25 cm²">
Here's the javascript :
function makeSummary() {
var summary = [];
$steps.not(":last").each(function (i, step) {
$step = $(step);
summary.push('<p><b>' + $step.data('name') + '</b></p>');
var $ch = $('input[type="checkbox"]:checked', $step);
var $qty = $('input.quantity', $step).filter(function() {
return this.value !== '0';
});
var $selected = $ch.add($qty);//jQuery collection of checkeboxes, or quantity fields, or a mixture of both.
if (!$selected.length) {
summary.push('<p>No items selected</p><br />');
} else {
$selected.each(function (i, s) {
var $s = $(s);
var prefix = ($s.hasClass('quantity')) ? ($s.nextAll("input.product").val() + ' : ') : '';
summary.push('<p>' + prefix + $s.val() + '</p><br />');
});
}
});
return summary.join('');
}
By doing it this way, the function remains general with regard to the number of steps, but also with regard to the composition of each step; it will handle completely specialized "checkbox step(s)" and "quantity step(s)", and (should you ever have the need) mixed "checkbox/quantity step(s)". In every case, the selected items will be summarized in their original DOM order.
