在摘要页面上显示用户输入

已采纳

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:

<form id="customisesystem" method="post" action="">
  <div id="first-step">
    <div class="steps">
      <p><b>Step 1 of 3</b></p>

        <?php $posts = get_field('options');
                                if( $posts ):
                                $items = 0;
                                foreach( $posts as $post): // variable must be called $post (IMPORTANT)

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('<a href="#" class="back-to-product">Back</a>').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>');

    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.
