Duplicate dynamic select boxes using clone()

I have a div in my code which I need to duplicate as the user clicks on the Add button. In the div there are 2 dropdowns one which is populated dynamically from database and the other one dynamically populated based on the first dropdown selection.
I have achieved duplicating the div using jQuery clone(). But the dynamically populating feature isn't working for the first dropdown divs so as the second one. Also, sometimes when I select an option in parent div, that's also showing weird selections.
var count = 1;
$('#add-new').click(function() {
//clone
var row = $('#scope-brand-div').clone(true);
row.appendTo('#clone-parent');
//add new ids
var scopeselect = $('select.scope-select');
var brandselect = $('select.brand-select');
$(row).find(scopeselect).attr('id', 'project-scope' + count);
$(row).find(brandselect).attr('id', 'brands_used' + count);
count++;
});
<form action="add_project" method="POST">
<h4>Project Scope <button class="clone" name="addnew" id="add-new">Add</button></h4>
<div class="row">
<div class="col-md-6">
<div class="row" id="clone-parent">
<div id="scope-brand-div">
<div class="col-md-6">
<div class="form-group">
<label for="scope"><?php echo $this->lang->line('xin_project_scope');?></label>
<select name="scope" class="form-control select-border-color border-warning scope-select" data-plugin="select_hrm" data-placeholder="<?php echo $this->lang->line('xin_project_scope');?>" id="project-scope">
<option value=""></option>
<?php foreach($all_project_scope as $scope) { ?>
<option value="<?php echo $scope->scope_id; ?>">
<?php echo $scope->scope_name; ?>
</option>
<?php } ?>
</select>
</div>
</div>
<div class="col-md-6">
<div class="form-group" id="brands-ajax">
<label for="brands_used"><?php echo $this->lang->line('xin_brands_used');?></label>
<select name="brands_used" id="brands_used" class="form-control select-border-color border-warning brand-select" data-plugin="select_hrm" data-placeholder="<?php echo $this->lang->line('xin_brands_used');?>">

How to use ajax to populate input with select option with data from database?

The question I've got in my test goes like so.
You have 1 select with 2 options(item number1 and item number2) and 2 input fields(price,weight). How would you make the input fields change without writing in them?
So after a long time of searching and trying stuff out (without much luck) I've learned that I need to use ajax for this to work. so I have tried a bunch and this is the code I've tried edit so it would work.
getAllproduct is just a select that fetches all the data inside my table with products. this is id, name, item_number, price, weight. anyhow here is my code
<?php
$sth = $db->prepare("SELECT `price`,`weight` FROM product");
$sth->execute();
$row = $sth->fetch(PDO::FETCH_ASSOC);
$row = array();
json_encode($row);
?>
product.php
<div class="form-group col-2">
<label for="product">Item number</label>
<?=#$error['product']?>
<select class="form-control" name="product" id="product" onChange="getproduct(this.value)">
<?php foreach ($csv->getAllproduct() as $csv) { ?>
<option value="<?= #$csv->id ?>" selected><?= #$csv->product?></option>
<?php } ?>
</select>
</div>
<div class="form-group col-2">
<label for="weight">weight</label>
<?=#$error['weight']?>
<input type="text" name="weight" id="weight" class="form-control">
</div>
<div class="form-group col-2">
<label for="price">price</label>
<?=#$error['price']?>
<input type="text" name="price" id="price" class="form-control">
</div>
<div class="input-group">
<button type="submit" style="margin-left:15px; margin-bottom: 15px; z-index: 5" class="btn btn-success" value="Opret" name="btn_opret_maal">Submit</button>
</div>
<script>
function getproduct(val){
$.ajax({
type:"POST",
url:"pages\call.php",
data: 'product='+val,
success: function(response){
var result = JSON.parse(response);
if (result.response == true) {
var data = result.rows;
$("#weight").val(data[0].weight);
$("#price").val(data[0].price);
}else if (result.response == false) {
$('#product').append('<option>No products were found!</option>');
}
}
});
}
</script>
What I expect to be able to do is select an item number and it will automatically populate the inputfields price and weight with the data inside the database from the item number.
I haven't learned a lot of Ajax/js so Any help is appreciated.
Attempt: on other project using this code. havent gotten it to work yet.
<form class="row" method="POST" >
<div style="border-color:#dddddd;" class="dropdown-divider col-12"></div>
<script>$('#Varenummer').on('change', function() {
var selectedOption = $(this).find('option:selected');
$('#Tolminus').val(selectedOption[0].dataset.Tolminus);
$('#Tolplus').val(selectedOption[0].dataset.Tolplus);
});
</script>
<div class="form-group col-2">
<label for="Varenummer">Varenummer</label>
<?= #$error['Varenummer'] ?>
<select class="form-control" name="Varenummer" id="Varenummer">
<?php
foreach ($csv->getAllVarenummer() as $csv) {?>
<option value="<?= #$csv->id ?>" data-Tolminus="<?= #$csv->Tolminus ?>"
data-Tolplus="<?= #$csv->Tolplus ?>"><?= #$csv->Varenummer ?></option>
<?php }?>
</select>
</div>
<div class="form-group col-2">
<label for="Tolminus">Tol -</label>
<?= #$error['Tolminus'] ?>
<input type="text" name="Tolminus" id="Tolminus" class="form-control" value="">
</div>
<div class="form-group col-2">
<label for="Tolplus">Tol +</label>
<?= #$error['Tolplus'] ?>
<input type="text" name="Tolplus" id="Tolplus" class="form-control" value="">
</div>
<div class="input-group">
<button type="submit" style="margin-left:15px; margin-bottom: 15px; z-index: 5" class="btn btn-success" value="Opret" name="btn_opret_maal">Submit</button>
</div>
the jquery scrips and others are added in the footer.

As you asked above in comments: i need it to the input to change when i select an option. can i still only use php?...
Yes.
You might not need ajax at all. For your task I'd recommend to preload weight and price values into data- attributes of corresponding option elements. Then, on the select change, just get those values and paste them to inputs.
$('#product').on('change', function() {
var selectedOption = $(this).find('option:selected');
$('#weight').val(selectedOption[0].dataset.weight);
$('#price').val(selectedOption[0].dataset.price);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group col-2">
<label for="product">Item number</label>
<select class="form-control" name="product" id="product">
<option disabled selected>Choose product...</option>
<option value="1" data-weight="100" data-price="1000">Product 1</option>
<option value="2" data-weight="50" data-price="200">Product 2</option>
<option value="3" data-weight="25" data-price="115">Product 3</option>
</select>
</div>
<div class="form-group col-2">
<label for="weight">weight</label>
<input type="text" name="weight" id="weight" class="form-control">
</div>
<div class="form-group col-2">
<label for="price">price</label>
<input type="text" name="price" id="price" class="form-control">
</div>
<div class="input-group">
<button type="submit" style="margin-left:15px; margin-bottom: 15px; z-index: 5" class="btn btn-success" value="Opret" name="btn_opret_maal">Submit</button>
</div>
For the PHP generated select (assuming the getAllproduct method returns weight and price properties):
...
<div class="form-group col-2">
<label for="product">Item number</label>
<?=#$error['product']?>
<select class="form-control" name="product" id="product">
<?php foreach ($csv->getAllproduct() as $csv) { ?>
<option value="<?= #$csv->id ?>" data-weight="<?= #$csv->weight ?>" data-price="<?= #$csv->price ?>"><?= #$csv->product?></option>
<?php } ?>
</select>
</div>

Dynamic Select box using javascript multifield in Codeigniter

Good day,

For example i have 1 default set of color, but then i click the Add More it adds another set of color but when i posting it in my controller it always return the first color and disregard the other added set of color. This is the sample image set of color
Can someone help me on this? I've been stucked for 4days now.
Here's my view code:
<div class="form-content">
<div class="row">
<div class="col-md-12">
<p><button type="button" id="btnAdd" class="btn btn-primary">Add Color</button></p>
<br/>
</div>
</div>
<div class="row group">
<div class="col-md-5">
<div class="form-group">
<label></label>
<select name="color1[]" id="color1" class="form-control" >
<option value="" > Color 1</option>
<?php foreach($colors as $color): ?>
<option value="<?php echo $color['colorID']; ?>">
<?php echo $color['colorDesc']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<div class="col-md-5">
<div class="form-group">
<label></label>
<select name="color2[]" id="color2" class="form-control" >
<option value="" > Color 2</option>
<?php foreach($colors as $color): ?>
<option value="<?php echo $color['colorID']; ?>">
<?php echo $color['colorDesc']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<button type="button" class="btn btn-danger btnRemove">X</button>
</div>
</div>
</div>
</div>
And here's the script
<script type="text/javascript">
$(".form-content").multifield({
section: ".group",
btnAdd:"#btnAdd",
btnRemove:".btnRemove",
});
</script>
And here's my Controller
$color1 = $this->input->post('color1');
$color2 = $this->input->post('color2');
for($i = 0; $i < count($color1); ++$i) {
echo $make = $color1[$i];
}
I just started using Codeigniter newbie in short. Please help me to fix this. Thanks in advance.

Try this (I not tested):
HTML:
<div class="form-content">
<div class="row">
<div class="col-md-12">
<p>
<button type="button" id="btnAdd" class="btn btn-primary">Add Color</button>
</p>
<br/>
</div>
</div>
<?php $count=0 ; if($this->input->post('color1')) $count = count($this->input->post('color1')); for($i=0;$i<$count,$i++):?>
<div class="row group">
<div class="col-md-5">
<div class="form-group">
<label></label>
<select name="color1[<?php echo $i;?>]" id="color1" class="form-control" <?php set_select( 'color1['.$i. ']',$color[ 'colorID']);?>>
<option value=""> Color 1</option>
<?php foreach($colors as $color): ?>
<option value="<?php echo $color['colorID']; ?>">
<?php echo $color[ 'colorDesc']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<div class="col-md-5">
<div class="form-group">
<label></label>
<select name="color2[<?php echo $i;?>]" id="color2" class="form-control">
<option value=""> Color 2</option>
<?php foreach($colors as $color): ?>
<option value="<?php echo $color['colorID']; ?>" <?php set_select( 'color2['.$i. ']',$color[ 'colorID']);?>>
<?php echo $color[ 'colorDesc']; ?>
</option>
<?php endforeach; ?>
</select>
</div>
</div>
<div class="col-md-2">
<div class="form-group">
<button type="button" class="btn btn-danger btnRemove">X</button>
</div>
</div>
</div>
<?php endfor;?>
</div>
in controller (you can also add validation):
...
if($this->input->post('color1')) {
$result = array();
$count = count($this->input->post('color1'));
for($i=0;$i<$count;$i++) {
if($this->input->post('color1['.$i.']') && $this->input->post('color2['.$i.']')) {
$result[$i] = ['color1'=>$this->input->post('color1['.$i.']'),'color2'=>$this->input->post('color2['.$i.']')];
}
}
print_r($result);
}
...

<script>
var element = document.getElementById("category_id");
element.onchange = function(){

hiddenDiv.style.display = (this.value=="")?"none":"block";}
</script>

You should try something like blew
get select value on change using javascript/jquery
<div class="form-group" id="img_upload">
<label>Postavi sliku:</label>
<input type="file" name="userfile" size="20">
</div>
$('#kategorije').on('change', function(){
var value = $(this).find(":selected").text();
if (value == 1) {
$("#img_upload").hide();
} else {
$("#img_upload").show();
}
});

Base from the html you provided, write a javascript like this:
$(function(){
$('#kategorije').on('change', function(){
var selected = $(this).val();
if (selected == 1) {
// hide the parent element of input
$('input[name=userfile]').parent().show();
} else {
// show the parent element of input
$('input[name=userfile]').parent().hide();
}
});
});
