JS function not found when calling PHP function on server but works on local server

As stated in the title my code works in local but not on server.
More precisely, when i call whatever PHP function it doesn't find my JS function.
To sum it up : The goal here is to generate an excel (.XLS) file from an HTML table which is created by retrieving data from a database. Everything works flawlessly in local with my Wamp server but when I move it to server I get this error when calling the JS function getDashboardResumeJ ():
DashboardResume.php:124 Uncaught ReferenceError: getDashboardResumeJ is not defined
If I remove all the PHP in the main file everything works when on server.
PHP in main file :
<button id="buttonXLS" href="#" onclick="exportTableToExcel('tableRecap', 'Rapport Mensuel <?php echo $year . '/' . $month?>')">Export to Excel</button>
<table style="display:none" id="tableRecap" >
<tr>
<td style="font-weight: bold">Nom et prénom</td>
<?php $arrayId = array(selectTableEmploye('nom', 'prenom')); ?>
</tr>
<tr>
<td style="font-weight: bold">Date d'entrée</td>
<?php selectTableEmploye('date_embauche'); ?>
</tr>
<tr>
<td style="font-weight: bold">Date de sortie</td>
<?php selectTableEmploye('date_depart'); ?>

<tr>
<td style="font-weight: bold">Remarque 1</td>
<?php selectTableTimesheet('commentaire1',$arrayId,$month,$year); ?>

Thanks for your help,
Have a great day

For those who have the same kind of problem, the server I was working on didn't have the same PHP version as the one I was working in local.
Try phpinfo() both in local and on your server to check your PHP version is the same.

Javascript - perform operation vertically and horizontally with dynamic text input

need help i am working with some text inputs here that are dynamic depending on how many the user enter. what i wanted to do is to compute the text inputs automatically after user input value using onkeyup javascript.
here the php and html code:
<?Php
$x = 10;
$i = 0;
for($i=0; $i<$x; $i++){
echo "<input type='text' onkeyup='multiply()' id='tb1'>";
echo "x";
echo "<input type='text' onkeyup='multiply()' id='tb2'>";
echo "=";
echo "<input type='text' onkeyup='multiply()' id='tb3'>";
echo "<br>";
}
?>
total:<input type='text' onkeyup='multiply()' id='tb4'>
and here's the javascript:
<script>
function multiply(){
var textbox1 = document.getElementById('tb1').value;
var textbox2 = document.getElementById('tb2').value;
var result = parseFloat(textbox1) * parseFloat(textbox2);
if(!isNaN(result))
{
document.getElementById('tb3').value = result;
}
}
</script>
now, the first row of text inputs works fine but the remaining text inputs doesn't I know i'm missing something here and i can't figure it out, how can
i compute horizontally those values from tb1 and tb2 then display it on tb3
and compute vertically all the values of tb3 and display it in tb4. any help is much appreciated.TIA

Well all rows contain elements with same ids. So row 1 will contain elements with ids: tb1, tb2, tb3. Row 2 will also contain elements with ids tb1, tb2 and tb3.
The id of each element on a page needs to be unique. You can make the ids unique by appending the row number to the id. For example:
<?php
$x = 10;
$i = 0;
for($i=0; $i<$x; $i++){
echo "<input type='text' onkeyup='multiply(" . $i . ")' id='tb" . $i . "-1'>";
echo "x";
echo "<input type='text' onkeyup='multiply(" . $i . ")' id='tb" . $i . "-2'>";
echo "=";
echo "<input type='text' onkeyup='multiply(" . $i . ")' id='tb" . $i . "-3'>";
echo "<br>";
}
?>
Total: <input type='text' id='tb4'> <input type='button' onclick='CalculateSum()' title='Calculate Sum'>
Your JavaScript code will then look as follows:
<script>
function multiply(row) {
var textbox1 = document.getElementById('tb' + row + '-1').value;
var textbox2 = document.getElementById('tb' + row + '-2').value;
var result = parseFloat(textbox1) * parseFloat(textbox2);
if(!isNaN(result))
{
document.getElementById('tb' + row + '-3').value = result;
}
}
function CalculateSum() {
let total = 0;
for (let i=0; i < 10; i++) {
total += document.getElementById('tb' + i + '-3').value;
}
document.getElementById('tb4').value = total;
}
</script>

I can't save specific selected value. it saved all data from database

i am inserting multiple data. what happen is when i select a project from drop down list. it save all data from selection. please check the image below first
function sample($con){
$select = "SELECT * FROM project_tbl";
$select_result = mysqli_query($con,$select);
if (mysqli_num_rows($select_result)> 0) {
while ($row = mysqli_fetch_assoc($select_result)) {
echo "<option value=".$row['project_name'].">" .$row['project_name']."</option>";
}
}
}
*html codes (i used drop down list to populate data from database)
<td class="pro">
<select class="pro">
<option value=""><?php sample($con); ?></option>
</select>
</td>
*ajax codes (adding, saving and removing)
$(document).ready(function(){
var count = 1;
$('#add').click(function(){
count = count + 1;
var html_code = "<tr id='row"+count+"'>";
html_code += "<td class='pro'><select class='pro'><option value=''><?php sample($con); ?></option></select></td>";
html_code += "<td contenteditable='true' class='desc'></td>";
html_code += "<td contenteditable='true' class='comp'></td>";
html_code += "<td contenteditable='true' class='entry'></td>";
html_code += "<td contenteditable='true' class='remarks'></td>";
html_code += "<td><button type='button' name='remove' data-row='row"+count+"' class='btn btn-outline-danger btn-xs remove' title='remove'><i class='fa fa-times' aria-hidden='true'></i></button></td>";
html_code += "</tr>";
$('#crud_table').append(html_code);
});
$(document).on('click', '.remove', function(){
var delete_row = $(this).data("row");
$('#' + delete_row).remove();
});
$('#save').click(function(){
var desc = [];
var pro = [];
var comp = [];
var entry = [];
var remarks = [];
$('.desc').each(function(){
desc.push($(this).text());
});
$('.pro').each(function(){
pro.push($(this).text());
});
$('.comp').each(function(){
comp.push($(this).text());
});
$('.entry').each(function(){
entry.push($(this).text());
});
$('.remarks').each(function(){
remarks.push($(this).text());
});
$.ajax({
url:"insert_inspection.php",
method:"POST",
data:{desc:desc, pro:pro, comp:comp, entry:entry, remarks:remarks},
success:function(data){
alert(data);
$("td[contentEditable='true']").text("");
$('select').prop('selectedIndex',0);
for(var i=2; i<= count; i++){
$('tr#'+i+'').remove();
}
}
});
});
});
Here is what happen when I save.
database
I am new in PHP.
insert_inspection.php
<?php
$con = mysqli_connect("localhost", "root", "", "pms");
if (isset($_POST["desc"])){
$desc = $_POST["desc"];
$pro = $_POST["pro"];
$comp = $_POST["comp"];
$entry = $_POST["entry"];
$remarks = $_POST["remarks"];
$query = '';
for($count = 0; $count<count($desc); $count++){
$desc_clean = mysqli_real_escape_string($con, $desc[$count]);
$pro_clean = mysqli_real_escape_string($con, $pro[$count]);
$comp_clean = mysqli_real_escape_string($con, $comp[$count]);
$entry_clean = mysqli_real_escape_string($con, $entry[$count]);
$remarks_clean = mysqli_real_escape_string($con, $remarks[$count]);
if($desc_clean != '' && $pro_clean != '' && $comp_clean != '' && $entry_clean != '' && $remarks_clean != ''){
$query .= 'INSERT INTO `inspection_tbl`(`description`, `project_name`, `completion`, `entry`, `remarks`) VALUES("'.$desc_clean.'", "'.$pro_clean.'", "'.$comp_clean.'", "'.$entry_clean.'", "'.$remarks_clean.'");
';
}
}
if($query != ''){
if(mysqli_multi_query($con, $query)){
echo 'Item Data Inserted';
}else{
echo 'Error';
}
}else{
echo 'All Fields are Required';
}
}
?>

it is saved as such because your select element only has one option value
modify it from:
<td class="pro"> <select class="pro"> <option value=""><?php sample($con); ?></option> </select> </td>
to:
<td class="pro">
<select class="pro">
<option value=""></option>
<?php sample($con); ?>
</select>
</td>
and modify your select element handler to push only your selected item
something like this:
$('.pro').each(function(){
if($(this).prop("selected")) {
pro.push($(this).text());
}
});
or modify this part to something like:
$(".pro > option:selected").each(function(){
pro.push($(this).text());
});

Update php SQL when checkbox check (no submit button)

I am pulling data out of a database and displaying in a table. I would like my checkbox, when checked/unchecked, to auto-update the value in the database without using a submit button to trigger the action. I'm new to AJAX and tried to adapt some code. I cannot get it to work. One major thing I don't understand is what '#state_span' is for?
Data Page (HTML)
$sql = "SELECT * FROM Orders ORDER BY " .$order;
$myData = mysqli_query($dbconnect, $sql);
while ($record = mysqli_fetch_array($myData)){
if ($record['Sent'] == 0) {
$sent = "";
} else {
$sent = "checked";
}
if ($record['Paid'] == 0) {
$paid = "";
} else {
$paid = "checked";
}
echo "<tr>";
echo '<td class="MenuLeft">' . $count . "</td>";
echo '<td class="MenuMid">' . $record['Name'] . "</td>";
echo '<td class="MenuRight"><input type="checkbox"
name="Sent"
id="'. $record['ID'] .'"
class="ChkSwitch"' . $sent . ' ></td>';
echo '<td class="MenuRight"><input type="checkbox"
name="Paid"
id="'. $record['ID'] .'"
class="ChkSwitch"' . $paid . ' ></td>';
echo "</tr>";
echo '<script>
$(document).ready(function() {
$(".ChkSwitch").click(function() {
var id = this.id;
var col = this.name; //Tell us what column to update
var state = this.checked ? 1 : 0;
$("#state_span").load("ChkUpdate.php?d="+id+"&col="+col+"&state="+state);
}
}
</script>
';
PHP
$id = $_GET['id'];
$state= $_GET['state'];
$col= $_GET['col'];
include("dbconnect.php");
$query = "UPDATE Orders SET '$col' = '$state' WHERE ID = '$id' ";
mysqli_query($dbconnect, $query);

I want dynamically change table. In column "FROM" and "TO" is value from database. This automatically subtract value (TO-FROM) and sum from this value is down. But when user change some value in column "FROM" or "TO", number will be count automatically. Thank you so much for every advice.

That's because you use the same ID for multiples TDs. You can't do that as an ID is supposed to be used once and help to identify a resource.
instead of an ID, you could use a class :
<table>
...
<tr>
<td><input type="text" class="txtCal num1" value="5" /></td>
<td><input type="text" class="txtCal num2" value="10" /></td>
<td><input type="text" class="txtCal2 remainingval" value="...">
</tr>
...
</table>
Then with jQuery, you can have access to your row values like this :
$('#myTable tr').each(function(){
var total = parseFloat($(this).find('.num2').val());
var val2 = parseFloat($(this).find('.num1').val());
...
var ansD = $(this).find(".remainingval");
ansD.val(total - val2);
});
Also let me point that mysql functions are deprecated and you should not use them anymore. Use PDO instead. (See Why shouldn't I use mysql_* functions in PHP?)
