Fields Added Via Javascript not posting Data into $POST

I have created a form which can be dynamically changed using the buttons included. These buttons allow for more input fields to be added/removed. The issue is that the input fields created are not posting any data/ Values in those fields not being added to the $POST array on the submit of the form.
The main functions below resposible for adding and removing rows is RemoveRows() and addRows()
What should happen is that on submit all values in the form should be "posted" then I can access all of those fields via $_POST["nameOfField"].
The way I have currently approached this is to create an input fields with the relevant id's and names then append that field to where the "hard coded" fields exists.
From my initial debugging none of the fields that have been added via javascript are in $Post which I have checked via var_dump($_REQUEST);
I have also seen that the nodes that are added are not elements of the form tag even though the nodes are added between the opening and closing tag. This can be seen in the doBeforeSubmit() Function where we can see all elements that are children of the and this never changes as rows are added/removed.

PHP:
<?php
var_dump($_REQUEST)
?>
UPDATE:
The code has been changed to use a php array by adding square brackets into the name which produces the following html:
<input type="text" id="partNum0" class="form-control" name="partNum[]">
<input type="text" id="partNum1" name="partNum[]" class="form-control">
<input type="text" id="partNum2" name="partNum[]" class="form-control">

You just need to use the name property of the input and add [] at the end, as GrumpyCrouton said. PHP parse it as an array, and you can access it as:
$partNum = $_POST["partNum"];

FIXED: It turns out the above code did not have any issues with the logic or the way it should work, in the source code in visual studio the indentation of some of the Divs was off causing the browser to have issues in rendering the form correctly hence why the added boxes were not included in the form and their values not POSTED.
As a heads up to anyone with maybe a similar issue, it pays to have your code neat.

How should I put limit inside for loop using if condition using javascript

My goal is that only 15 quantities of input elements can be accepted, once the user enters 16 it should say that only 15 input elements is allowed. However I don't know how will I do this. I tried putting condition inside for but it is not not working. I am a little bit confused on this
Here is my HTML code
<div class="form-group">
<label> Quantity: </label>
<input class="form-control" name="quantity" type="number" id="get_Elem"
required>
<br>
<input type="button" id="sb_add_ctrl" name="is_Sub" class="btn btn-
primary" value="Add Control Number">
</div>
<div class="form-group" name="parent" id="parent"></div>
Here is my JS code
$(document).on('click', '#sb_add_ctrl', function() {
var element = $('#get_Elem').val();
var input;
var parent = $(document.getElementById("parent"));
var value = $('#sel_control_num').val();
functionPopulate(parent);
if (isNaN(element)) {
return;
}
for (var i = 0; i < element; i++) {
if(should I do it here??){
}
value = value.replace(/(\d+)$/, function(match, element) {
const nextValue = ++match;
return ('0' + nextValue).slice(1);
});
document.getElementById("parent").style.padding = "5px 0px 0px 0px";
document.getElementById("parent").innerHTML += '<br><input type="text"
value="' + value +
'" class="form-control" name="get_Input_show[]" required>'
}
});

You can check if the element value is < 16 if yes then only add html else show error message.
Demo Code :
$(document).on('click', '#sb_add_ctrl', function() {
var element = $('#get_Elem').val();
var input;
//var value = $('#sel_control_num').val();
var value = 12;
//functionPopulate(parent);
if (isNaN(element)) {
return;
}
//check if elemnt value if < 16
if (element < 16) {
$("#parent").empty() //empty div
for (var i = 0; i < element; i++) {
/* value = value.replace(/(\d+)$/, function(match, element) {
const nextValue = ++match;
return ('0' + nextValue).slice(1);
});*/
document.getElementById("parent").style.padding = "5px 0px 0px 0px";
document.getElementById("parent").innerHTML += '<br><input type="text" value = "' + value + '" class="form-control" name="get_Input_show[]" required>';
}
} else {
alert("only 15") //show error
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group">
<label> Quantity: </label>
<input class="form-control" name="quantity" type="number" id="get_Elem" required>
<br>
<input type="button" id="sb_add_ctrl" name="is_Sub" class="btn btn-
primary" value="Add Control Number">
</div>
<div class="form-group" name="parent" id="parent"></div>

There are two ways in which you can restrict it
You can use maxLength property of an input tag, which will restrict the user to input the 16th character.
You can keep checking the value in the input field and show error if the length is more than 15 character. To do this you can use onkeypress event on input, like
HTML
<input type="text" id="test" onkeypress="test()" />
JS:
<script>
function test() {
alert('Hi')
}
</script>

add and delete divs created in JS

So I got this working almost perfectly but for some reason deleteInput() won't delete 2 div's in a row and I can not figure it out. The function still works but it won't delete. can someone explain why this is?

Javascript:
var counter = 1;
var limit = 5;
var newdiv = document.createElement('div');
function addInput(divName) {
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
} else {
newdiv = document.createElement('div');
newdiv.innerHTML = "Entry " + (counter + 1) + " <br><input type='text' name='myInputs[]'>";
document.getElementById(divName).appendChild(newdiv);
counter++;
}
}
function deleteInput() {
for (var x = 0; x < counter; x++){
newdiv.removeChild(newdiv.childNodes[0]);
}
counter--;
}
Base format before JS
Added another Div w/JS

This may solve your problem if I understood what you are trying to do correctly. I've added an email class to your divs to remove the emails more easily.
var counter = 1;
var limit = 5;
function addInput(divName) {
if (counter == limit) {
alert("You have reached the limit of adding " + counter + " inputs");
} else {
var newdiv = document.createElement('div');
newdiv.className = "email"
newdiv.innerHTML = "Entry " + (counter + 1) + " <br><input type='text' name='myInputs[]'>";
document.getElementById(divName).appendChild(newdiv);
counter++;
}
}
function deleteInput(divName) {
var emails = document.getElementsByClassName("email");
if (emails.length) {
document.getElementById(divName).removeChild(emails[emails.length - 1]);
counter--;
}
}
<div id="parent" class="first-div">
<label for="email">Email</label><input type="email" id="mail" name="usermail">
<div class="line-left shrinkM-underline"></div>
<div id="child" class="showE flex-it">
<div>
<input type="email">
<div class="line-left shrinkM-underline"></div>
</div>
<span type="button" value="Remove Element" onClick="deleteInput('parent','child');" class="remove"> <strong>Remove</strong></span>
</div>
<input onclick="addInput('parent', 'child');" class="input-button" type="button" value="+Add another email">

Display the form array inputs value before submitting the form

i have a single page which is divided into two sections.So at first first section is seen and we need to fill the inputs value and when we click go to next page button then the first section is now hidden and second section is shown.Then only we can submit the form.
Now what i want is that in the first section, i have four inputs like shown below
<div class="room_details_first col-md-12" id="first_order">
<div class="col-md-3">
<input type="text" placeholder="Food items" name="others_food_items[]" data-view-id="#location"/>
</div>
<div class="col-md-3">
<input type="text" placeholder="Hotel Name" name="others_hotel[]"/>
</div>
<div class="col-md-3">
<input type="text" placeholder="Hotel price" name="others_hotel_price[]"/>
</div>
<div class="col-md-3">
<input type="text" placeholder="Customer Price" name="others_client_price[]"/>
</div>
</div>
Now by using jquery i have append the inputs and the code is shown below
function add_others_order(){
var output="";
output+= '<div class="room_details_first col-md-12" id="first_order">';
output+='<div class="col-md-3"><input type="text" placeholder="Food items" name="others_food_items[]" data-view-id="#location"/></div>';
output+='<div class="col-md-3"> <input type="text" placeholder="Hotel Name" name="others_hotel[]"/> </div>';
output+='<div class="col-md-3"><input type="text" placeholder="Hotel price" name="others_hotel_price[]"/></div>';
output+='<div class="col-md-2"> <input type="text" placeholder="Customer Price" name="others_client_price[]"/></div>';
output+='<div class="col-md-1" ><i class="fa fa-remove"></i></div>';
output+='</div>';
$('#first_order').after(output);
}
now what i need is i need to save the inputs value before submitting and list it in second section of the page.i have tried to do it but i am failed many times. And i have also found similar answers which is given below
Display the data entered in a form before submitting the form
Guys i need help.

Here is what you want, you will get all input's value and you can do
what ever you want with it.
function nextStep() {
var allFields = document.getElementsByTagName("input");
//console.log(allFields);
for (var index in allFields) {
console.log('name : '+allFields[index].name);
if (allFields[index].type == "text") { // you can change condition by name instead of type
if (allFields.hasOwnProperty(index)) {
var attr = allFields[index];
console.log(attr.value)
}
}
}
}
<div class="col-md-3">
<input type="text" placeholder="Food items" name="others_food_items[]" data-view-id="#location" />
</div>
<div class="col-md-3">
<input type="text" placeholder="Hotel Name" name="others_hotel[]" />
</div>
<div class="col-md-3">
<input type="text" placeholder="Hotel price" name="others_hotel_price[]" />
</div>
<div class="col-md-3">
<input type="text" placeholder="Customer Price" name="others_client_price[]" />
</div>
<input type="button" onclick="nextStep()" value="Next step">

I think this is what you want, or as close to what you need, I add an Id attribute so you can do add/remove:
var stored_data = [];
stored_data.total = 0;
$('#dummy').on('click', function(){
var obj = {
id: stored_data.length,
food: food.value,
hotel_name: hotel_name.value,
hotel_price: hotel_price.value,
customer_price: customer_price.value
};
stored_data.push(obj);
stored_data.total += parseInt(obj.customer_price);
//$('#first_section').hide();
var output = '<div class="room_details_first col-md-12" id="first_order">';
output += '<div>Order ' + obj.id + '</div>';
output += '<div class="col-md-3">Food: ' + obj.food + '</div>';
output += '<div class="col-md-3">Hotel Name: ' + obj.hotel_name + '</div>';
output += '<div class="col-md-3">Hotel Price' + obj.hotel_price + '</div>';
output += '<div class="col-md-2">Customer Price' + obj.customer_price + '</div>';
output += '<div class="col-md-1" ><i class="fa fa-remove"></i></div>&nbsp';
$('#new_section').append(output);
$('#total').text(stored_data.total);
});

Here's a way to do it by using clone() on the whole first order and do some modifications to add the link and change duplicate ID and last item column class.
First use serializeArray() to get the values to store
var values = $('#first_order :input').serializeArray();
console.log(values);
then clone , modify and insert
var link = '<div class="col-md-1" ><i class="fa fa-remove"></i>LINK</div>';
// clone first order and update ID
var $first = $('#first_order').clone().attr('id', 'first-order_2');
// modify column on last one and add the link
$first.children(':last').toggleClass('col-md-2 col-md-3').after(link);
// insert in second position
$('#second').append($first)
DEMO

By taking reference of Jigar7521, i tried to do the following way
var allFields = document.getElementsByClassName("others_order");
var others_total_price='0';
var others_food_items=new Array();
var others_hotel_name=new Array();
var others_hotel_price=new Array();
var others_client_price=new Array();
//var others['food_items'] = new Array();
var ficounter=0;
var hcounter=0;
var hpcounter=0;
var cpcounter=0;
Array.prototype.forEach.call(allFields, function(el) {
if(el.name=='others_client_price[]'){
others_client_price[cpcounter]=el.value;
cpcounter++;
others_total_price=parseFloat(others_total_price)+parseFloat(el.value);
}
if(el.name=='others_food_items[]'){
others_food_items[ficounter]=el.value;
ficounter++;
}
if(el.name=='others_hotel[]'){
others_hotel_name[hcounter]=el.value;
hcounter++;
}
if(el.name=='others_hotel_price[]'){
others_hotel_price[hpcounter]=el.value;
hcounter++;
}
});
$('#others_total_price').val(others_total_price);
var others_output="<h4>Others Order</h4>";
for(var i=0;i<=ficounter;i++){
others_output+='<div ><div class="col-md-12"><div class="col-md-3">'+others_food_items[i]+'</div><div class="col-md-3">'+others_hotel_name[i]+'</div><div class="col-md-3">'+others_hotel_price[i]+'</div><div class="col-md-3"> '+others_client_price[i]+'</div></div></div>';
}
$('#others_id').html(others_output);
it worked but i get errors like undefined
i tried to console.log every array and i got what i did not have expected

jQuery Dynamic Add Form Field, Remove Form Field

next = next + 1;
var newIn = '<br /><br /><input autocomplete="off" class="span3" id="field' + next + '" name="field' + next + '" type="text" data-provide="typeahead" data-items="8"><button id="b'+next+'" onClick="$(this).prev().remove();$(this).remove();" class="btn btn-info" type="button">-</button>';
var newInput = $(newIn);
console.log(addto);
$(addto).after(newInput);
if(next>1)
$("button#b"+next).after(newInput);
$("#field" + next).attr('data-source',$(addto).attr('data-source'));
$("#count").val(next);
}
DEMO FIDDLE

In my example, I was building a form that would allow users to add multiple input names if they had more than one dog.
var counter = 0
jQuery(function () {
$(".newDog").click(function(){
counter ++;
if (counter < 4) {
var elem = $("<input/>",{
type: "text",
name: `dogname${counter}`
});
} else {
alert("You can only add 4 Dog Names")
}
var removeLink = $("<span/>").html("X").click(function(){
$(elem).remove();
$(this).remove();
counter --;
});
$(".dogname-inputs").append(elem).append(removeLink);
});
})
