Sending URL with parameters and using javascript values in parameters

For online payment I have to send parameters to an URL. Calculations in my site written in Javascript, Online payment company requires PHP parameters like MD5 hashing.

I tried creating hidden form and put required javascript values into input fields. And succeded.

My hidden form:

<form action="https://test.millikart.az:7444/gateway/payment/register" method="get" id="hiddenForm">
<input name="mid" value="unicopy" type="hidden">
<input name="amount" id="amount" value="" type="hidden">
<input name="currency" value="944" type="hidden">
<input name="description" value="" id="description" type="hidden">
<input name="reference" value="UNICSH3195319" type="hidden">
<input name="language" value="az" type="hidden">    
<input name="signature" value="<?php echo htmlspecialchars($signature); ?>" type="hidden">
<button type="button" class="btn btn-secondary" data-dismiss="modal" onClick="clearList()" >Reset</button>
<button  class="btn btn-primary" id="odenis" >Pay</button>
</form>

<script>
document.getElementById("amount").value= parseInt(yekunMeblegArray.reduce(myFunc));
document.getElementById("description").value= description;

//AJAX
$.ajax({
type: 'POST',
url: "index.php",
data: $("#hiddenForm").serialize(), 

success: function(response) { 
alert("succeed")},
});
</script>

But before sending the URL I have to prepare $signature with PHP that should include value from javascript

My PHP:

<?php 

  $mid="unicopy";
  $amount=$_POST['amount'];
  $currency="944";
  $description=$_POST['desc'];
  $reference="UNICSH3195319";
  $language="az";
  $key="123456qwerty";

  $signature=strtoupper(md5(strlen($mid).$mid.strlen($amount).$amount.strlen($currency).$currency.(!empty($description)? strlen($description).$description :"0").strlen($reference).$reference.strlen($language).$language.$key));

  ?>

As you can see $signature includes $amount and $description variables that should get its values from javascript. I tried sending form data with AJAX but couldn't succeed. How can I achieve this? Any kind of help is appreciated.

My guess is that either:

1) document.getElementById("amount").value= parseInt(yekunMeblegArray.reduce(myFunc)); does not set a proper value (you can debug with console.log statement underneath value being set.

Or

2) $("#hiddenForm").serialize() this function call does not generate data in the way you think it does. You should console.log to investigate.

I recommend you look at contentType and dataType properties of the ajax object in:
