Add Checked Table Rows to Email Body

I have a table where each row can be selected by checking a checkbox. Whatever rows are selected, I am wanting those rows to be pasted to the body of an email that pops up when the "Checkout" button is pressed.
Currently, whenever I hit the "Checkout" button, the email pops up and it will display the first row in the table, whether selected or not, but nothing more.
How can I get multiple selections displayed based on if it is checked?

<section id="checkout-btn">
<button id="checkout" name="order" onclick="sendMail(); return false">Checkout</button>

Javascript that adds data to email:
function sendMail() {
var link = "mailto:me#example.com"
+ "?subject=" + encodeURIComponent("Order")
+ "&body=" + encodeURIComponent($('.loc').data('loc')) + '\xa0\xa0' + encodeURIComponent($('.rp-code').data('rp-code')) + '\xa0\xa0' + encodeURIComponent($('.sku').data('sku')) + '\xa0\xa0' + encodeURIComponent($('.special-id').data('special-id')) + '\xa0\xa0' + encodeURIComponent($('.description').data('description')) + '\xa0\xa0' + encodeURIComponent($('.quantity').data('quantity')) + '\xa0\xa0' + encodeURIComponent($('.unit').data('unit')) + '\xa0\xa0' + encodeURIComponent($('.quantity_num').data('quantity_num'));
window.location.href = link;
}

While this is terrbile idea to send emails via JS like this, You can try:
function sendMail(){
var link = "mailto:me#example.com"
+ "?subject=" + encodeURIComponent("Order")
+ "&body=";
var body = '';
$('table tr input[name="check"]:checked').each(function(){
var current_tr = $(this).parent().parent();
var loc = current_tr.find('.loc').data('loc');
body += encodeURIComponent(loc) + '\xa0\xa0';
var loc =current_tr.find('.rp-code').data('rp-code');
body += encodeURIComponent(loc) + '\xa0\xa0';
});
body += '"';
link += body;
console.log(link);
}
You need to iterate over every TR that contains checkbox and check if it's :checked .
Then add avery data that You need into your's body var.

You are calling array elements like rows[0][0][rp-code] outside of PHP tags.
You could create the tables more easily by keeping all nested inside the PHP tags and by echoing each table elements.
Like so:
echo <tr>;
echo <td name="rows[0][0][rp-code]">Some Text</td>;
echo </tr>;
You could also do everything inside javascript, but this depends on your preferences

Provide Validation for JavaScript Spinner

I have a multiple column table with one of the columns being a checkbox. Whenever a checkbox is checked, it displays an extra column called Quantity # which contains a spinner where the user can either type in a number or use the up/down arrows to select a number. Currently, if you use the up/down arrows, it can go no lower than 1 and no higher than the quantity number associated with that row in the table.
However, for example, if the quantity is 80 and the user types in 85 themselves, then that will also be accepted. I do not want this accepted as you can not request 85 when there is only 80 quantity available.
So how can I provide validation to the spinner so that a user can not enter a number higher than the quantity number? Also, is there a way to make it so that the spinner will not allow any alphabetical characters and will only allow numerical characters?

JavaScript for spinner:
$(function () {
$(".check").change(function(){
$(this).closest('tr').find('td.quantity_num').toggle(this.checked);
console.log($('input.check').is(':checked'));
var quantity = $(this).closest('tr').find('td.quantity').data('quantity');
console.log(quantity);
if($('input.check').is(':checked'))
$(this).closest('table').find('th.num').toggle(true);
else
$(this).closest('table').find('th.num').toggle(false);
$(this).closest("tr").find(".spinner" ).spinner({
spin: function( event, ui ) {
if ( ui.value > quantity ) {
$( this ).spinner( "value", quantity );
return false;
} else if ( ui.value <= 1 ) {
$( this ).spinner( "value", 1 );
return false;
}
var test = ui.value;
sessionStorage.setItem("test", JSON.stringify(test));
var testtrue = sessionStorage.getItem("test");
console.log(JSON.parse(testtrue));
}
});
});
});
JavaScript that gets info from a checked row and displays it in my email client once the "Checkout" button is clicked:
function sendMail() {
var dataItems = [
{ 'clss':'.loc', 'prop':'loc' },
{ 'clss':'.rp-code', 'prop':'rpCode' },
{ 'clss':'.sku', 'prop':'sku' },
{ 'clss':'.special-id', 'prop':'specialId' },
{ 'clss':'.description', 'prop':'description' },
{ 'clss':'.quantity', 'prop':'quantity' },
{ 'clss':'.unit', 'prop':'unit' }
];
var link = "mailto:me#example.com" + "?subject=" + encodeURIComponent("Order") + "&body=";
link += $('#merchTable tr input[name="check"]:checked').closest('tr').get().map(function(tr) {
var str = dataItems.map(function(item) {
return encodeURIComponent($(tr).find(item.clss).data(item.prop)) + '\xa0\xa0';
}).join('');
str += encodeURIComponent($(tr).find('.spinner').spinner('value')) + '%0D%0A';
return str;
}).join('') + '%0D%0A';
console.log(link);
window.location.href = link;
}

Using AJAX to Send Data on Button Click

I have a table with multiple columns (index.php). One column is a checkbox. Whenever the checkbox is checked, it displays another column where you can select a quantity.
I want to be able to hit a button called "Add to Order" and have it use AJAX to add any selected rows to the index-order.php page. After all selections have been made, I want to be able to click the "Checkout" button and have it take me to the index-order.php page where it should be displaying all of the added selections in a table.
I know how to navigate to the index-order.php page so my main question is how can I add the selected rows to the index-order.php page by using ajax when pressing the button?
Index.php code:
<form name="form1" action="index-order.php">
<section id="checkout-btn">
<button type="submit" id="checkout" name="order">Checkout</button>
</section>
</form>
<form name="form2" method="POST" action="index-order.php">
<section id="addToOrder">
<button type="submit" class="order" id="order" name="order" value="AddToOrder">Add to Order</button>
</section>

<th>Special ID</th>
<th>Description</th>

<?php
foreach($_POST['rows'][0] as $row):
?>

<?php
endforeach;

</table>
<?php endif; ?>
JavaScript:
$(function () {
$("#order").click(function() {
//reset the logger
$('#log').empty();
$('#merchTable input:checkbox:checked').each(function() {
//for each checked checkbox, iterate through its parent's siblings
var array = $(this).parent().siblings().map(function() {
return $(this).text().trim();
}).get();
console.log(array);
//to print the value of array
$('#log').append(JSON.stringify(array))
var request = $.ajax({
type: 'post',
url: 'index-order.php',
data: array,
success: function(){
alert('success');
},
error: function(){
alert('failure');
}
});
})
});
});

To pass data from one page to another using php you will have to use a session.
So in your ajax call just save your data into the session like so:
add-to-cart.php
session_start();
if (!isset($_SESSION['shopping_cart'])) {
$_SESSION['shopping_cart'] = [];
} else {
$_SESSION['shopping_cart'][] = [
'id' => $_POST['item_id'],
'amount' => $_POST['amount']
];
}
If you then click your checkout button and navigate via a page reload to your index-order.php, you could then access the data via the same session index.
session_start();
if (isset($_SESSION['shopping_cart'])) {
// display your data
} else {
echo "Your shopping cart is empty.";
}

Send Table Row Data via AJAX Based on Checkbox Checked

I have a table with multiple columns (index.php). One column is a checkbox. Whenever the checkbox is checked, it displays another column where you can select a quantity.
I want to then be able to hit a button called "Add to Order" and have it use AJAX to add any selected rows to the index-order.php page. After all selections have been made, I want to be able to click the "Checkout" button and have it take me to the index-order.php page where it should display all of the added selections in a table.
I know how to navigate to the index-order.php page so my main question is how can I add the selected rows to the page while using ajax and staying on the current page when doing so?

JavaScript (obviously needs some work. Posting what I have so far):
$(function () {
$('#form2').on('submit', function (e) {
if($('input.check').is(':checked')) {
$(this).closest('tr');
e.preventDefault();
var request = $.ajax({
type: 'post',
url: 'index-order.php',
data: $('#form2').serialize(),
success: function(){
alert('success');
},
error: function(){
alert('failure');
}
});
}
});
});

What you can do is get all the siblings of the current checked checkbox and based on that get all the columns and separate the data to finally send it via ajax.
You can do something like this:
$('#form2').on('submit', function (e) {
$checkbox = $(this).find('input.check:checked').parent('td'); //Finds the checked checkbox's column inside #form2
$otherColumns = $checkbox.nextAll(); //Gets all the siblings
});
The above code will get you all the other columns next to the checked checkbox inside your form. What you an do next is travel across $otherColumns and get each individual value using $otherColums.eq(n).html() where n is the number of the column you are trying to get.
