Get the unique total scores of students

I have a form on my school web application where teachers are able to add scores for students and at the end of each row, the total, which is the sum of input values is automatically calculated per student.
The problem is that it output the total of all the students instead of the total of individual students on all the rows even ones with no scores added.
How do I get the unique total value for each row?
Below is my code
<?php if($class_id >= 1 && $class_id <= 4 && $student['is_secmid'] == 1){?>
<form method="post" action="<?php echo site_url('admin/examgroup/entrymarks') ?>" id="assign_form1111">
<input type="hidden" id="max_mark" value="<?php echo $subject_detail->max_marks; ?>">
<?php
if (isset($resultlist) && !empty($resultlist)) {
?>
<div class="row">
<div class="col-md-12">
<input type="hidden" name="exam_group_class_batch_exam_subject_id" value="<?php echo $exam_group_class_batch_exam_subject_id; ?>">
<div class="table-responsive">
<table class="table table-striped">
<thead>
<tr>
<th>C.A 1 (10.0)</th>
<th>C.A 2 (10.0)</th>
</tr>
</thead>
<tbody>
<?php if (empty($resultlist)) {
?>
<tr>
<td colspan="7" class="text-danger text-center"><?php echo $this->lang->line('no_record_found'); ?></td>
</tr>
<?php
} else {
foreach ($resultlist as $student) {
?>
<tr class="std_adm_<?php echo $student['admission_no']; ?>">
<input type="hidden" name="prev_id[<?php echo $student['exam_group_class_batch_exam_students_id'] ?>]" value="<?php echo $student['exam_group_exam_result_id'] ?>">
<input type="hidden" name="exam_group_student_id[]" value="<?php echo $student['exam_group_class_batch_exam_students_id'] ?>">
<td><?php echo $student['admission_no']; ?></td>
<td style="white-space: nowrap;"><?php echo $student['lastname'] . " " . $student['firstname']; ?></td>
<td> <input type="number" class="marksssss2 form-control" min="0" max="10" name="exam_group_student_ca1_<?php echo $student['exam_group_class_batch_exam_students_id']; ?>" value="<?php echo $student['exam_group_exam_result_get_ca1']; ?>" step="any"></td>
<td> <input type="number" class="marksssss3 form-control" min="0" max="10" name="exam_group_student_ca2_<?php echo $student['exam_group_class_batch_exam_students_id']; ?>" value="<?php echo $student['exam_group_exam_result_get_ca2']; ?>" step="any"></td>
<td> <output class="result"></output></td>
</tr>
<?php
}
}
?>
</tbody>
</table>
</div>
<?php if ($this->rbac->hasPrivilege('exam_marks', 'can_edit')) { ?>
<button type="submit" class="allot-fees btn btn-primary btn-sm pull-right" id="load" data-loading-text="<i class='fa fa-spinner fa-spin '></i> Please Wait.."><?php echo $this->lang->line('save'); ?>
</button>
<?php } ?>
</div>
</div>
<?php } ?>
<script>
const $inputs = $('input[type="number"]')
$inputs.change(function() {
var total = 0;
var parent = $(this).closest('.row');
parent.find('input[type="number"]').each(function() {
if ($(this).val() != '') {
total += parseInt($(this).val());
}
});
parent.find('.result').html(total);
});
</script>

you missed class row on <tr> and you are trying to find it on closest div from javascript, and you are getting this (<div class="row">), it have all the (<input type="number").
you forget to add class to TR. Add class row on <tr> so you can get all (<input type="number") inside the tr.
because of not added class on TR you are facing issue that all total have same numbers.

how to send dynamic data using ajax to controller codeigniter

I have a form contain looping input tag that is used for adding data. the looping form is work, and the problem is i didn't know how to retrieve that looping data in controller code igniter. please help!
this is my view (form)
<form action="#" id="ap_data">
<div class="table-responsive">
<table class="table table-striped table-hover" id="mkt">
<thead>
<tr>
<th>KR</th>
<th>NP</th>
<th>KP</th>
</tr>
</thead>
<tbody>
<?php $number =0;
$id = "id";
$idkr = "idkr";
$np = "np";
$idkp = "idkp";?>
<?php foreach ($perb as $value) {
$number++; ?>
<tr>
<input type="hidden" name="<?php echo $id.$number; ?>" value="<?php echo $value->idp ?>"/>
<td>
<input type="text" placeholder="" name="<?php echo $idkr.$number; ?>" value="<?php echo $value->idkp ?>" class="form-control">
</td>
<td>
<select name="<?php echo $np.$number; ?>" class="form-control">
<option value="1">1 (AS)</option>
<option value="2">2 (Bold)</option>
<option value="3">3 (Seed)</option>
</select>
</td>
<td>
<input type="text" placeholder="" name="<?php echo $idkp.$number; ?>" value="<?php echo $value->idkp ?>" id="class="form-control">
</td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
<div class="form-group">
<button type="button" onclick="test_kond()" class="btn btn-success col-lg-12">Test Kond</button>
</div>
</form>
here' is my view (Ajax function)
<script type="text/javascript">
var test_kond;
$( document ).ready(function() {
test_kond = function () {
var data_ap;
data_ap = $("#ap_data").serialize();
$.ajax({
type: "POST",
url: "<?php echo site_url('HoldBotCtrl/kond_ajax')?>",
data: data_app,
success: function() {
alert(data_ap);
}
});
};
});
and here's my controller
function kond_ajax(){
$k_t = $this->Hb_model->select_kr();
$j_kr = count($kr_total);
$idkr = "idkr";
$np = "np";
$idkp ="idkp";
for ($i=1; $i <= $jj_kr ; $i++) {
$idkrr = $idkr.$i;
$npp = $np.$i;
$idkpp = $idkp.$i;
$data_ap = array(
$idkrr => $this->input->post($idkrr),
$npp => $this->input->post($npp),
$idkpp => $this->input->post($idkpp)
);
print_r($data_ap);
}
and this is result of print_r
idkr1Array ( [idkr1] => [np1] => [idkp1] => ) idkr2Array ( [idkr2] => [np2] => [idkp2] => )
the value still null, i need to get the data from $this->input->post();.
how to fix this??

I think serilize() method creates a URL encoded string where as you want to send data via POST method in ajax. You could try this way.
var test_kond;
$( document ).ready(function() {
test_kond = function () {
var data_ap;
data_ap = new FormData($("#ap_data"));
$.ajax({
type: "POST",
url: "<?php echo site_url('HoldBotCtrl/kond_ajax')?>",
data: data_app,
success: function() {
alert(data_ap);
}
});
};
});

Just try by changing field names like below:
<form action="#" id="ap_data">
<div class="table-responsive">
<table class="table table-striped table-hover" id="mkt">
<thead>
<tr>
<th>KR</th>
<th>NP</th>
<th>KP</th>
</tr>
</thead>
<tbody>
<?php $number =0;
$id = "id";
$idkr = "idkr";
$np = "np";
$idkp = "idkp";?>
<?php foreach ($perb as $value) {
$number++; ?>
<tr>
<input type="hidden" name="data[<?= $number ?>]['id']" value="<?php echo $value->idp ?>"/>
<td>
<input type="text" placeholder="" name="data[<?= $number ?>]['idkr']" value="<?php echo $value->idkp ?>" class="form-control">
</td>
<td>
<select name="data[<?= $number ?>]['np']" class="form-control">
<option value="1">1 (AS)</option>
<option value="2">2 (Bold)</option>
<option value="3">3 (Seed)</option>
</select>
</td>
<td>
<input type="text" placeholder="" name="data[<?= $number ?>]['idkp']" value="<?php echo $value->idkp ?>" id="" class="form-control">
</td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
<div class="form-group">
<button type="button" onclick="test_kond()" class="btn btn-success col-lg-12">Test Kond</button>
</div>
</form>
and in your controller :
function kond_ajax(){
print_r($this->input->post());
}
I hope this will help :)

Unable to use Jquery.load() feature properly

I am trying to filter results that will be displayed to user based on selection, but, its not displaying, properly, I do not know what I am doing wrong. I process using GET on the same page (users.php?rid=). This is how it displays when I select a value. Seems it loads the page twice into the div
The Select Button
<select name="role_id" id="role_id" style="width: 150px;"
onchange="">
<option value="">Select User</option>
<?php
$rid = 0;
if (isset($_GET['rid'])) {
$rid = clean($_GET['rid']);
}
$roles = get_user_roles();
foreach ($roles as $row):
?>
<option
value="<?php echo $row['role_id']; ?>"<?php if (isset($rid) && $rid == $row['role_id']) echo 'selected'; ?>>
<?php echo $row['name']; ?>
</option>
<?php endforeach; ?>
</select>
RESULT DIV
<div id="filter_result">
<table class="table table-striped" >
<thead>
<tr>
<th><div>#</div></th>
<th><div>Name</div></th>
<th><div>Email</div></th>
<th><div>User Type</div></th>
<th><div>Options</div></th>
</tr>
</thead>
<tbody>
<?php
if ($rid < 1) {
$users = get_users();
} else {
$users = get_role_users($rid);
}
if ($users->num_rows < 1) {
echo '<div class = "alert alert-warning text-center">There are no Students for this Class.... <a class="btn btn-primary btn-sm" href="add_user.php">Add User</a></div>';
}
$count = 1;
foreach ($users as $row):?>
<tr>
<td><?php echo $count++; ?></td>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['email']; ?></td>
<td><?php echo get_role_name($row['role_id']); ?></td>
<!--Options-->
<td>
<!--Change Role-->
<div class="btn-group">
<button type="button" class="btn btn-primary btn-sm dropdown-toggle"
data-toggle="dropdown">
Change Role <span class="caret"></span>
</button>
<ul class="dropdown-menu dropdown-default pull-right" role="menu">
<?php $roles = get_user_roles();
foreach ($roles as $row2):
?>
<li>
<a href="change_roles.php?rid=<?php echo $row2['role_id'].'&uid='.$row['user_id'];?>">
<?php echo $row2['name']; ?>

<?php endforeach; ?>
</ul>

<a href="delete_user.php?id=<?php echo $row['user_id']; ?>"
onclick="confirm('Are You sure?')" class="btn btn-danger"> Delete</a>
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
</div
JAVASCRIPT
<script>
$(document).on('change', 'select#role_id', function () {
var role_id = $(this).val();
$('#filter_result').load('users.php?rid='+role_id, '#filter_result');
});
</script>
It should display like this

Since you are Checking selection on the same page, you can assign id to your body tag, for example
<body id="page_body">
then use #page_body.load(), it will work
$('#page_body').load('users.php?rid='+role_id, '#filter_result');

Passing javascript variable to PHP using ajax but it gives error

I am trying to pass my JavaScript variable using Ajax into my PHP script but that doesn't work it given me error that it is undefined index. both codes are in different files but both of them are accessible on the main page.
Here's my script.php
<script>
function get_child_options(){
var parentID = jQuery('#parent').val();
jQuery.ajax({
url: '/**/**/**/child_categories.php',
type: 'POST',
data: {parentID : parentID},
success: function(data){
jQuery('#child').html(data);
},
error: function(){alert("Something Went Wrong with child options. ")},
});
}
jQuery('select[name="parent"]').change(get_child_options);
</script>
And this is my php file
<?php
require_once $_SERVER['DOCUMENT_ROOT'].'/ **/core/init.php'; //Including database path stored in init.php
$parentID = (int)$_POST['parentID'];
$childQuery = "SELECT * FROM categories WHERE parent = '$parentID' ORDER BY category";
ob_start();
?>
<option value="">Select <strong>Child</strong> Category</option>
<?php while ($child = mysqli_fetch_assoc($childQuery)): ?>
<option value="<?= $child['id']; ?>"><?= $child['category']; ?></option>
<?php endwhile; ?>
<?php
echo ob_get_clean();
?>
in script the #parent is a form id i am passing to javascript using jQuery.
because of variable is not accessible PHP is not running query.
This is my products.php the main where page where this is happening

Is there any other way to do it? What I am trying to do is when user selects parent category I want child category to arrange as per parent category.

Try this:
<script>
function get_child_options(){
var parentID = $(this).val();
jQuery.ajax({
url: '/**/**/**/child_categories.php',
type: 'POST',
data: {'parentID' : parentID},
success: function(data){
jQuery('#child').html(data);
},
error: function(){alert("Something Went Wrong with child options. ")},
});
}
jQuery('select[name="parent"]').change(get_child_options);
</script>
Getting the Value by $(this) and putting single quotes around parentID data: {'parentID' : parentID},
