Recap of email order form

I have a contact form which works fine (a form page, a processing file which sends the emails, and thank you page), I’d to use it as a base to create a simple email order form.
The new form works fine by itself, I mean if I use a simple page (as action) to display the data “submitted” it displays correct info like this:
<form id="order-form" method="POST" action="order.php">

I’d like to integrate it with the above mentioned processing file so that the order is emailed, a copy to myself, and a copy to the potential customer, a recap on the thank you page would be the icing.

Following are my code, in order: the working contact form, the contact processing, the new order form, and the simple display page.

The server has php 7.3 if please let me know if you see some outdated code also in the working form.
Of course all improvements, and tidy up of my code is more than welcome.
Thank you

New order form same as the contact form save that instead of textarea for message I put the following

<form id="order-form" method="POST" action="order.php">
... other fields same of the contact form ...
<div class="form-group">
	<input type="checkbox" name="product[]" value="1" />
	<label for="message">Panni €1,50/pz</label>
	<input type="number" class="form-control" name="quantity_panno" />
<div class="form-group">
	<input type="checkbox" name="product[]" value="2" />
	<label for="message">baby €2,00/pz</label>
	<input type="number" class="form-control" name="quantity_baby" />
<div class="form-group">
	<input type="checkbox" name="product[]" value="3" />
	<label for="message">Mascherine €2,50/pz</label>
	<input type="number" class="form-control" name="quantity_mascherina" />
<div class="form-group">
	<input type="checkbox" name="product[]" value="4" />
	<label for="message">Dispenser €3,50/pz</label>
	<input type="number" class="form-control" name="quantity_dispenser" />

Simple display test page

	if (isset ($_POST["product"])) {
		$c = count($product);
		$price = 0.00;
		for ($i=0;$i<$c;$i++) {
			if ($product[$i]==1) {
				$tot_p = $price + 1.50 * $quantity_panno;
				echo "hai scelto " . $quantity_panno . " panni per € " . number_format((float)$tot_p, 2, '.', '') . "<br />";
			if ($product[$i]==2) {
				$tot_b = $price + 2.00 * $quantity_baby;
				echo "hai scelto " . $quantity_baby . " baby per € " . number_format((float)$tot_b, 2, '.', '') . "<br />";
			if ($product[$i]==3) {
				$tot_m = $price + 2.50 * $quantity_mascherina;
				echo "hai scelto " . $quantity_mascherina . " mascherine per € " . number_format((float)$tot_m, 2, '.', '') . "<br />";
			if ($product[$i]==4) {
				$tot_d = $price + 3.00 * $quantity_dispenser;
				echo "hai scelto " . $quantity_dispenser . " dispenser per € " . number_format((float)$tot_d, 2, '.', '') . "<br />";

		$total = $tot_p + $tot_b + $tot_m + $tot_d;
		echo "totale ordine: € " . number_format((float)$total, 2, '.', '');
	else {
		echo "scegli qualcosa";

If all you want to do is to display the contents of the order in your “thank you” confirmation page, and the issue is that the contents of your $_POST array are no longer present after you processed it, a simple way would be to do something like

$_SESSION['postarray'] = $_POST;

after you’ve done the processing, but before you redirect to the thankyou page. You could then use the same code.

It would probably be better to build a new array containing just the items that the customer ordered, which would make it more simple to display. Or your processing page could build the confirmation page html as it processes the form contents, and stick that in a session variable.

In here

<form method="POST" action="contact_processing.php#contact">

what’s the point of the #contact on the end? I know what it does in a simple href, but I don’t think I’ve seen it in a form action string.

Thanks for the reply.
I forgot to mention that I am not a coder, and the contact form is not my code.
That said let me get into more details, the “order” code is parly mine after lots of trials to get it work, afte I had found a snip for the checkbox part to which I added the quantity, and totals.

Besides the thank you recap, which as said would be the icing, I don’t know how to integrate that to the email body, which is more relevant.

I would like to add the Simple display test page result to the emails sent to myself, and the user.

You are perfectly right, if I only knew how to do so, same as your suggestion of the postarray.

If I recall correctly I had put it to get to the anchor on the html page.

The contact_processing does have an html part which I believe is what you are referring to.

You can see in the section headed “Prepare email body text” how the email body is made up. You could experiment by adding some code to that to see how it changes the body text, and gradually add each part of your simple display text page to the email body. Do a single part at a time and see how it changes, and if you run into errors, feel free to post the appropriate code sections on here for further advice.
