<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 :)

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'); ?>

</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.

Get data attribute from an array of select box

I have an account form in which the all account are being pulled from my mysql database into a dropdown menu. The user selects the account from the dropdown menu then the account code field is automatically populated via the data-acc attribute. I have added a button to add more account.
It works at first set of input and select box, but not in the next one

Something like this should work.

File Handling POST Data not being passed

So I'm trying to do Ajax POST in my wordpress site which is used in checking if checkboxes are checked and getting their values to get updated on the database on click. Using the usual PHP form submit is the easiest but the fields that I'm trying to get is outside the form.
After button click, I created an alert if the data that I need is being picked up (and they are) so I can continue with the Ajax POST. However, the POST data is not showing when I inserted an alert on the second file.
Here's my code (content-orders.php):

I hope someone can help. Thanks!

I'm a bellend.
The form should just have an ID and add the form ID to all the fields outside the form.
<form id="bulk_action_filter" class="form-inline" method="post">
<select id="bulk_action_stat" name="bulk_action_stat">
<option value="">Bulk Actions</option>

<input form="bulk_action_filter" type="submit" name="filter_bulk_actions" id="check-all" value="Apply"/>
</form>
<input form="bulk_action_filter" id="select-item" name="bulk_actions_check[]" type="checkbox" value="<?php echo $loop->post->ID; ?>">

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
<?php
require_once $_SERVER['DOCUMENT_ROOT'].'/Online Store/core/init.php'; //Including database path stored in init.php

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},
