Passing certain form values over with a POST

What i am trying to do is, once my form is submitted, it will pass certain values from a form to PayPal.
This is my form code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class="form-horizontal" action="<?php echo whichPPUrl(); ?>" method="post" id="paypal_form" target="_blank">
<div class="form-group">

<script>

$(document).ready(function() {
// updates / adds the checkbox values
function updateSum() {

$(".sum:checked").each(function(i, n) {
let sum = parseFloat(total) + parseFloat($(n).val());
total = sum.toFixed(2);
});
$("#total").val(total);
}
// run the update on every checkbox change and on startup
$("input.sum").change(updateSum);
updateSum();
});
</script>
I am not the greatest with Ajax, i have done a basic example of what i think is the right way to go:
This function:
<script>
// pass the total value over to the form: <input type="hidden" name="amount" value="getTheCost()">
function getAndPassTheCost() {
return $("#total").val();
}
</script>
Would get the value from the input text box and pass it through to the post form.
This function:
<script>
// pass the form values over and deal with them on the backend: <input type="hidden" name="custom" value="getTheFormValues()">
function getTheFormValues() {
return $("form").serialize();
}
</script>
Would just serialize all the form data which i can then validate and process on the backend.
Have i over complicated the process? my issue is i'm not able to pass this data to the form whcih is then sent via POST to a PayPal script, any help in the right direction would be appreciated.

The inputs can only store strings they cannot store functions. Assign values to form controls by the .val() method. The functions getAndPassTheCost() and getTheFormValues() are useless. If you need to serialize the form, do it during the submit event. As for collecting all of the form values, that is done at submit event -- just ensure that whatever values you want sent has a [name] attribute.

function updateSum() {
var total = 0;
$(".sum:checked").each(function(i) {
let sum = parseFloat($(this).val());
total += sum;
});
$("#total, .total").val(total.toFixed(2));
}
$("input.sum").on('change', updateSum);
$('paypal_form').on('submit', function(e) {
$(this).serialize();

Add new created label and input-text to form using dom Javascript?

I have three fields that will be filled by the user.
one for the question, and the two others for the proposed answers. I want to give the user the possibility to add the third or as much as he wants propositions whenever he clicks at add proposition. I started coding the function but it's still missed
<head>
<script>
function myFunction(){
var x = document.createElement("LABEL");
var t = document.createTextNode("Titre");
x.appendChild(t);
}
</script>
</head>
<body>
<form id="myForm" method="POST" action="./exam_coordinates">
<label for="question"> Question </label> <br>
<input class="champ" type="textarea" name="question" id="question" value=""><br><br>
<label for="ans"> Answers </label> <br>
<input type="checkbox" name="ans1" id="ans1" values="" />
<input type="text" name="ans1" id="ans1" value=""><br>
<input type="checkbox" name="ans2" id="ans2" />
<input type="text" name="ans2" id="ans2" value=""><br>
<br>
<button onclick="myFunction()">Add proposition</button> <br><br><br>
<input type="submit" value="submit">
</form>
</body>

If I'm getting your question right, you need to add inputs to get more answers from user as he wants. If so, see the following -
var addButton = $('#add_button');
var wrapper = $('#more_answers');
$(addButton).click(function(e) {
e.preventDefault();
var lastID = $("#myForm input[type=text]:last").attr("id");
var nextId = parseInt(lastID.replace( /^\D+/g, '')) + 1;
$(wrapper).append(`<div><input type="checkbox" name="ans${nextId}" id="ans${nextId}" values="" /> <input type="text" name="ans${nextId}" id="ans${nextId}" value=""/>Delete<div>`);
});
$(wrapper).on("click", ".delete", function(e) {
e.preventDefault();
$(this).parent('div').remove();
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<body>
<form id="myForm" method="POST" action="./exam_coordinates">
<label for="question"> Question </label> <br>
<input class="champ" type="textarea" name="question" id="question" value=""><br><br>
<label for="ans"> Answers </label> <br>
<input type="checkbox" name="ans1" id="ans1" values="" />
<input type="text" name="ans1" id="ans1" value=""><br>
<input type="checkbox" name="ans2" id="ans2" />
<input type="text" name="ans2" id="ans2" value=""><br>
<div id="more_answers"></div>
<br>
<button id="add_button">Add proposition</button> <br><br><br>
<input type="submit" value="submit">
</form>
</body>

In your function, you have to append your label as well in its parent. Like below -
function myFunction() {
var form = document.getElementById("myForm");
var input = document.createElement("input");
form.appendChild(input)
}
<form id="myForm" method="POST" action="./exam_coordinates">
<label for="question"> Question </label> <br>
<input class="champ" type="textarea" name="question" id="question" value=""><br><br>
<label for="ans"> Answers </label> <br>
<input type="checkbox" name="ans1" id="ans1" values="" />
<input type="text" name="ans1" id="ans1" value=""><br>
<input type="checkbox" name="ans2" id="ans2" />
<input type="text" name="ans2" id="ans2" value=""><br>
<br>
<button type="button" onclick="myFunction()">Add proposition</button> <br><br>
<input type="submit" value="submit">
</form>
If you want to put your elements at any specific place, you should create a wrapper in your form element just like below -
function myFunction() {
let wrapper = document.getElementById("dynamic-fields");
var input = document.createElement("input");
wrapper.appendChild(input)
}
<form>
<!-- ...input fields... -->
<div id="dynamic-fields"></div> <br>
<!-- ...buttons.... -->
<button type="button" onclick="myFunction()">Add proposition</button>
</form>
This way it will put those dynamically generated elements on specific place in your form page.

Ask user for amount and user value in a form

I'm trying to integrate a payment method called SiamPay on my website but I don't know javascript :(
On SiamPay website they have this instructions:
Copy the following program code to your payment page and
dynamic generate the Amount show below by yourself
<form name="payForm" method="post" action="https://www.siampay.com/b2c2/eng/payment/payForm.jsp">
<input type="submit" name="submit" value="Buy">
<input type="hidden" name="amount" value="Amount">
<input type="hidden" name="merchantId" value="76117579">
<input type="hidden" name="orderRef" value="76117579">
<input type="hidden" name="currCode" value="764" >
<input type="hidden" name="successUrl" value="">
<input type="hidden" name="failUrl" value="">
<input type="hidden" name="cancelUrl" value="">
<input type="hidden" name="remark" value="">
<input type="hidden" name="lang" value="E">
<input type="hidden" name="payMethod" value="ALL">
</form>
Example in jsp:
<%
double amount = qty * unitPrice ;
%>
<form name="payForm" method="post" action="https://www.siampay.com/eng/payment/payForm.jsp">
<input type="submit" name="submit" value="Buy">
<input type="hidden" name="amount" value="<%= amount %>">
<input type="hidden" name="merchantId" value="76117579">
<input type="hidden" name="orderRef" value="76117579">
<input type="hidden" name="currCode" value="764" >
<input type="hidden" name="successUrl" value="">
<input type="hidden" name="failUrl" value="">
<input type="hidden" name="cancelUrl" value="">
<input type="hidden" name="remark" value="">
<input type="hidden" name="lang" value="E">
</form>
I would like to create a field where the user can input an amount to pay in THB (Thai currency) and transport that value to this field:
< input type="hidden" name="amount" value="<%= amount %>">.
I think this is relatively easy but because I never user javascript I'm a little confused.
I appreciate any help.
Thank you so much.
Best Regards,
Alex

There's no need to create an extra input field. You have to change the name=amount input's type to number so that it will become visible to the user. Now the user can enter a number of their choice and click the pay button to submit the payment form.
<form name="payForm" method="post" action="https://www.siampay.com/eng/payment/payForm.jsp">
<input type="submit" name="submit" value="Buy">
<input type="number" name="amount" value="" placeholder="Enter amount in THB ">
<input type="hidden" name="merchantId" value="76117579">
<input type="hidden" name="orderRef" value="76117579">
<input type="hidden" name="currCode" value="764" >
<input type="hidden" name="successUrl" value="">
<input type="hidden" name="failUrl" value="">
<input type="hidden" name="cancelUrl" value="">
<input type="hidden" name="remark" value="">
<input type="hidden" name="lang" value="E">
</form>

To set value to an element, you can use the document.getElementById().value function. Set the amount data into the Amount variable as shown below.
var Amount = 123;
Also, modify the input tag for the amount to include the same id:
<input type="hidden" name="amount" id="amtId" value="Amount">
var Amount = 123;
function setAmountValue() {
document.getElementById('amtId').value = Amount;
}
<form name="payForm" method="post" action="https://www.siampay.com/b2c2/eng/payment/payForm.jsp">
<input type="submit" name="submit" value="Buy" onclick="setAmountValue();">
<input type="hidden" name="amount" id="amtId" value="Amount">
<input type="hidden" name="merchantId" value="76117579">
<input type="hidden" name="orderRef" value="76117579">
<input type="hidden" name="currCode" value="764">
<input type="hidden" name="successUrl" value="">
<input type="hidden" name="failUrl" value="">
<input type="hidden" name="cancelUrl" value="">
<input type="hidden" name="remark" value="">
<input type="hidden" name="lang" value="E">
<input type="hidden" name="payMethod" value="ALL">
</form>

try something like this:
<form name="payForm" method="post" action="https://www.siampay.com/eng/payment
/payForm.jsp">
<input type="submit" name="submit" value="Buy">
<input type="hidden" id="amount" value="<%= amount %>">
<input type="hidden" name="merchantId" value="76117579">
<input type="hidden" name="orderRef" value="76117579">
<input type="hidden" name="currCode" value="764" >
<input type="hidden" name="successUrl" value="">
<input type="hidden" name="failUrl" value="">
<input type="hidden" name="cancelUrl" value="">
<input type="hidden" name="remark" value="">
<input type="hidden" name="lang" value="E">
</form>
<button id='cmdSend'>Click me</button>
<input id='howmuch' type="number" name="amount" value=1000>
And the JS:
document.getElementById("cmdSend").addEventListener("click", myFunction);
function myFunction() {
document.getElementById("cmdSend").innerHTML = "YOU CLICKED ME!";
//Get the value the user typed:
var Value = document.getElementById("howmuch").value;
console.log(Value);
//Set the value into the hidden input, can be done in 2 ways:
document.getElementById("amount").value = Value;
document.getElementById("amount").setAttribute('value',Value);
//Check the value got assigned:
console.log(document.getElementById("amount").value);
}

Use JavaScript checkbox value in HTML

I'd like to be able to use a total amount generated using javascriptand displayed on the page in a <span> field later on in an HTML form. The checkbox additions and subtractions work correctly, I have no issue with that. What I have not been able to figure out is how to use that value later on in an HTML field (shown below as the PayPal code).
I have this in the <head> which handles the javascript:
<head>
<script type="text/javascript">
var total = 0.00;
function test(item) {
if (item.checked) {
total += parseFloat(item.value);
} else {
total -= parseFloat(item.value);
}
//alert(total);
document.getElementById('Totalcost').innerHTML = total.toFixed(2);
}
</script>
</head>
The this adds/subtracts if a check box is checked:
<td class="column-3">
<br>
<label class="container">
<input type="checkbox" name="Shoes" value="2.95" onClick="test(this);">Select<span class="checkmark"></span>
</label>
</td>
<td class="column-3">
<br>
<label class="container">
<input type="checkbox" name="Clothes" value="2.95" onClick="test(this);">Select<span class="checkmark"></span>
</label>
</td>
Then I display the total with this:
Total Amount: $<span id="Totalcost">0.00</span>
All of this works correctly and checking/unchecking reflects on the Total Amount shown at the bottom of the page.
What I'd like to do is use the total amount that is show in the HTML below for the PayPal subscription link so that the amount is added into the
line.
<form name="_xclick" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_xclick-subscriptions">
<input type="hidden" name="business" value="myemailaddress.com">
<input type="hidden" name="item_name" value="Shows & Clothes">
<input type="hidden" name="item_description" value="Shows & Clothes">
<input type="hidden" name="currency_code" value="GBP">
<input type="hidden" name="no_shipping" value="1">
<input type="image" src="http://www.paypal.com/en_GB/i/btn/x-click-but20.gif" border="0" name="submit" alt="Make payments with PayPal - it\'s fast, free and secure!">
<input type="hidden" name="a3" value="TOTAL_AMOUNT">
<input type="hidden" name="p3" value="1">
<input type="hidden" name="t3" value="M">
<input type="hidden" name="src" value="1">
<input type="hidden" name="sra" value="1">
</form>
Is it possible to capture the 'totalcost' and have it dynamically added to the "a3" field in the PayPal form (where it says TOTAL_AMOUNT) for when the customer clicks the PayPal button it already has the correct value/amount in the form?
Thank you.

You can use document.getElementsByName. By default you'll get a NodeList. For example:
var a3 = document.getElementsByName("a3")[0];
a3.value = total.toFixed(2);
You can easily update its value.
Something like this:
var total = 0.00;
function test(item) {
if (item.checked) {
total += parseFloat(item.value);
} else {
total -= parseFloat(item.value);
}
document.getElementById("Totalcost").innerHTML = total.toFixed(2);
var a3 = document.getElementsByName("a3")[0];
a3.value = total.toFixed(2);
}

JavaScript/Jquery : Multiple input value with multiple id

I have one html form
<form>
<input type="hidden" name="id" value="1" /><input type="text" name="qty" />
<input type="hidden" name="id" value="2" /><input type="text" name="qty" />
<input type="hidden" name="id" value="3" /><input type="text" name="qty" />
<input type="hidden" name="id" value="4" /><input type="text" name="qty" />
<input type="submit"/>
</form>
When I submit form,Say for id = 1 , qty is 5 or for id = 3, qty is 8. How to get this values in java script or jquery and submit this information to server? I get all the input text values. But I cannot differentiate which qty is for which value?

You should not have two or more elements with the same name or id!
names & ids are meant to be unique.
try this:
<form>
<input type="hidden" name="id[1]" value="1" /><input type="text" name="qty[1]" id="qty1" value="" />
<input type="hidden" name="id[2]" value="2" /><input type="text" name="qty[2]" id="qty2" value="" />
<input type="hidden" name="id[3]" value="3" /><input type="text" name="qty[3]" id="qty3" value="" />
<input type="hidden" name="id[4]" value="4" /><input type="text" name="qty[4]" id="qty4" value="" />
<input type="submit"/>
</form>
You can acces the data in JS like this:
using the element name:
var qty1 = document.forms[0].elements["qty[1]"].value;
Using the element id:
var qty1 = document.getElementById("qt1").value;

Well, to me, your hidden inputs are useless : You say that for input text one is a corresponding hidden field id with a defined value. Then you just have to name your input correctly and you know which id or something is correspondant.
If you want to use jQuery (javascript) as you said, then just do something like this :
<form>
<input type="text" name="qty1" id="qty1" />
<input type="text" name="qty2" id="qty2" />
<input type="text" name="qty3" id="qty3" />
<input type="text" name="qty4" id="qty4" />
<input type="submit" name='submit' id="submitButton" value="submit"/>
</form>
<script>
$('document').on('click','#submitButton',function(event){
event.preventDefault();
//this prevents the click to submit, as you want to get values by javascript... remove this if you post it with php
console.log('QTY1 : '+$('#qty1').val()+' - QTY2 : '+$('#qty2').val()+' - QTY3 : '+$('#qty3').val()+' - QTY 4 : '+$('#qty4').val());
//This is with jQuery, javascript would look like addEventListeneer, and get values like document.getElementById('id').value;
//then, ajax something if you really want to post your form through javascript, but this is not a good solution...
});
</script>
Other solution, better to me, would be just to use php and post directly your form...
<?php
if(isset($_POST['submit'])){
//then, user has clicked on submit button
//CONSIDERED THAT YOU HAVE CHECKED IF THE FIELDS ARE NOT EMPTY
$qty1 = $_POST['qty1'];
$qty2 = $_POST['qty2'];
$qty3 = $_POST['qty3'];
$qty4 = $_POST['qty4'];
//do your stuff with the posted values...
}else{
echo '
<form method="POST" action="yourPage.php">
<input type="text" name="qty1" id="qty1" />
<input type="text" name="qty2" id="qty2" />
<input type="text" name="qty3" id="qty3" />
<input type="text" name="qty4" id="qty4" />
<input type="submit" name="submit" id="submitButton" value="submit"/>
</form>
';
}
?>
Hope it helps

Your html is perfectly valid, but you're not using the name of the elements to your advantage.
<input type="hidden" name="id1" value="1" /><input type="text" name="qty1" />
This will return:
id1=1&qty1=X
But in the end I think your hidden field is just wasting space. All you seem to need is the quantity field with a proper name.
<input type="text" name="qty1" />
<input type="text" name="qty2" />
...
If you use the same name for the elements it will still give you the desired data, but it might need some parsing to figure out "what is what".
<input type="text" name="qty" />
<input type="text" name="qty" />
...
This will basically return:
qty=X,Y (or qty=X&qty=Y)
item ----0-1

You could wrap each pair of hidden-text inputs in div element, then iterate through these divs and find these two inputs inside each of the div elements. It might look like this:
<form>
<div id="keyValuePairs">
<div class="pair">
<input type="hidden" name="id" value="1" /><input type="text" name="qty" />
</div>
<div class="pair">
<input type="hidden" name="id" value="2" /><input type="text" name="qty" />
</div>
<div class="pair">
<input type="hidden" name="id" value="3" /><input type="text" name="qty" />
</div>
<div class="pair">
<input type="hidden" name="id" value="4" /><input type="text" name="qty" />
</div>
</div>
<input type="submit" id="sendBtn"/>
</form>
Then iterate with Jquery
$("#sendBtn").click(function(){
var arr = [];
$("#keyValuePairs .pair").each(function(){
var val = $(this).find("input[name='id']").val();
var key = $(this).find("input[name='qty']").text();
var obj = { val:val, key:key };
arr.push(obj);
});
// some ajax call or any way you want to post data server
});
at the end of iteration, arr should contain objects with val property containing what is in the value property of hidden input, and key property containing what the text present in text inputs.
