Adding DropDown list in jQuery DataTable

I want to display table's data with jQuery DataTable and sometimes apply an extra data filtering, using the output of a dropdown select input.
The main code for fetching data (fetch.php) is:
<?php
include('db.php');
include('function.php');
$query = '';
$output = array();
$query .= "SELECT * FROM Part_tb ";
if(isset($_POST["search"]["value"]))
{
$query .= 'WHERE part_manufacturer LIKE "%'.$_POST["search"]["value"].'%" ';
$query .= 'OR part_id LIKE "%'.$_POST["search"]["value"].'%" ';
}
if(isset($_POST["order"]))
{
$query .= 'ORDER BY '.$_POST['order']['0']['column'].' '.$_POST['order']['0']['dir'].' ';
}
else
{
$query .= 'ORDER BY part_id ASC ';
}
if($_POST["length"] != -1)
{
$query .= 'LIMIT ' . $_POST['start'] . ', ' . $_POST['length'];
}
$statement = $connection->prepare($query);
$statement->execute();
$result = $statement->fetchAll();
$data = array();
$filtered_rows = $statement->rowCount();
foreach($result as $row)
{
$sub_array = array();
$sub_array[] = $row["part_manufacturer"];
$sub_array[] = $row["part_id"];
$sub_array[] = $row["part_category"];
$sub_array[] = $row["part_stock"];
$data[] = $sub_array;
}
$output = array(
"draw" => intval($_POST["draw"]),
"recordsTotal" => $filtered_rows,
"recordsFiltered" => get_total_all_records(),
"data" => $data
);
echo json_encode($output);
?>
while the DataTable is defined in index.php as follows:
var dataTable = $('#user_data').DataTable({
"processing":true,
"serverSide":true,
"order":[],
"ajax":{
url:"actions/fetch.php",
type:"POST"
},
"columnDefs":[
{
"targets":[0, 1],
"orderable":false,
},
],
});
In index.php, i've created 3 dependent dropdown lists, which load data from other tables. Now, i want to take the id of 3rd dropdown list and update the data of Part_tb in fetch.php accordingly. Below, you can see that when 3rd dropdown change, i call a function load_parts():
$(document).on('change', '#sub3_category_item', function(){
load_parts();
});
function load_parts()
{
var action = 'fetch_data';
var filter_part_id = $('#sub2_category_item').val();
$.ajax({
url:"actions/fetch.php",
method:"post",
data:{action:action, filter_part_id:filter_part_id},
success:function(data)
{
$('#user_data').DataTable().ajax.reload();
}
});
}
The problem is that i can't filter the data of fetch.php according to the selected id of #sub2_category_item. Could you help me on that?
I've modified the index.php as follows:
$(document).on('change', '#sub3_category_item', function(){
var filter_part_id = $('#sub3_category_item').val();
$('#user_data').DataTable().destroy();
fill_datatable(filter_part_id);
});
fill_datatable();
function fill_datatable(filter_part_id = '')
{
var dataTable = $('#user_data').DataTable({
"processing":true,
"serverSide":true,
"order":[],
"searching" : false,
"ajax":{
url:"actions/fetch.php",
type:"POST",
data:{filter_part_id:filter_part_id}
}
});
and fetch.php:
$query .= "SELECT * FROM Part_tb ";
if(isset($_POST['filter_part_id']) && $_POST['filter_part_id'] != '')
{
$query .= "SELECT * FROM Part_tb WHERE part_id IN (SELECT pcfit_name from Part_car_fit_tb WHERE pcfit_id ='".$_POST["filter_part_id"]."') ";
}
but dataTable crashes, when #sub3_category_item is selected. Any idea, how to filter datatable with the value $_POST["filter_part_id"]?

Export table to csv with multiple dropdowns

Im building a page with multiple selects inside each row, im using the select2 plugin to do that, my problem is: I did a lot of research but i sitll couldnt find a way of exporting this table to csv. I dont know if it is because of the placeholders that select2 plugin puts in each row or if its other error that i dont know that im making. I will leave some pics from my page and the script that i tried to do.
<form method="POST" action="select.php">

Javascript code stops working after page Load More .load()

When data is fetched on auto Load More, another JavaScript (which is given below) stops working.
Even when it shows the 1st page default it works there but after scrolling down it does not work.

What should I put in my updating.php when I need to update users status if online or offline every 5 seconds?

Hi I've made a messaging feature,it displays the receivers of the message in an account, beside the receiver's name is a green or red dot, for online or offline, it is successful when I log in 2 accounts and messaged each other, when I open the first account, the other account is offline, when I open the second account, the other is online, what my problem is I want to update their status in every five seconds so that their dot will be accurate whenever they log out or log in. I have made a javascript and ajax below this page left-col.php and I've tried copying the whole code, putting it to updating.php but it did not work, what should be the appropriate data inorder to update user receiver status in every 5 seconds inside the updating.php? and also, does my the javascript and ajax needs a library to be included that's why it didn't work? Please help.

A benefit can be assigned to an employee but firstly the code below shows the dynamic dropdown of employee and dynamic benefit checkboxes
<?php
$ctr = 0;
$employee = mysqli_query($conn, "SELECT * FROM housekeeping_employee") or DIE("Could not Select");
echo "<select class='indent' name = 'Employee'>";
while($listEmployee = mysqli_fetch_array($employee))
{
echo "<option value = ".$listEmployee['employeeid'].">".$listEmployee['firstname']."</option>";
}
echo "</select>";
echo "<br><be>";
echo "<div class='indent'>";
$benefits = mysqli_query($conn, "SELECT * FROM housekeeping_benefit")or DIE("SELECT Query not working.");
if(mysqli_num_rows($benefits))
{
while($row = mysqli_fetch_array($benefits))
{
$ctr++;
echo "<h6><input type = 'checkbox' name = 'benefits".$ctr."' value ='".$row['benefitid']."' >".$row['benefitname']." </input></h6> <be>";
if($ctr == 5){
echo"<br>";
$ctr=0;
}
}
echo "<br><input type='submit' class='btn btn-info' name='insert' value='Submit'/>";
}
echo "<input type='hidden' name='ctr' value='".$ctr."'/>";
echo "</form>";
?>
This is what the insert code of assigning benefits to employee looks like.
$employeeid = $_POST['Employee'];
for($a = 1; $a <= $_POST['ctr'] ; $a++)
{
if(isset($_POST['benefits'.$a]))
{
$benefitid = $_POST['benefits'.$a];
//echo "INSERT INTO `housekeeping_employeebenefits`(`employeeid`,`benefitid`) VALUES('$employeeid','$benefitid')";
mysqli_query($conn, "INSERT INTO `housekeeping_employeebenefits`(`employeeid`,`benefitid`) VALUES('$employeeid','$benefitid')") or DIE("Insert query is not working");
echo "Employee to Benefits successful!";
}
}
My main problem is how will I display checked checkboxes if the employee already has that benefit? I'm really lost
