Datatable reorder issue

I'm having an issue with the following code. What I'm trying to do is to populate a modal form with data from the row on which you pressed the edit button.
The script works fine until I try to reorder the table: when the table is reordered the script is getting the information of the pre-reordered table.
This is the script that get called when the edit button get clicked:
$(document).ready( function () {
//create datatable
//declaring a variable without var makes it global
table_movimenti = $('#movimenti').DataTable();
$('#movimenti table tbody tr td').on('click', function () {
$("#transaction_ID").val($(this).find("td:eq(6)").attr('id'));
$("#data_cont").val($(this).find("td:eq(0)").text());
$("#data_valuta").val($(this).find("td:eq(1)").text());
$("#importo").val($(this).find("td:eq(2)").text());
$("#divisa").val($(this).find("td:eq(3)").text());
$("#causale").val($(this).find("td:eq(4)").text());
var categoria=$.trim($(this).find("td:eq(5)").text());
$("#categoria option").each(function() {
if($(this).text() == categoria){
//$(this).prop("selected", true);
$(this).attr("selected", "selected");
return;
}
});
});
This is the table:
<?php
echo "<table id='movimenti' class='table table-bordered table-striped table no-margin'>";
echo "<thead>";
echo "<tr>";
echo "<th>Data contabile</th>";
echo "<th>Data valuta</th>";
echo "<th>Importo</th>";
echo "<th>Divisa</th>";
echo "<th>Causale</th>";
echo "<th>Categoria</th>";
echo "<th>Edit</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
while($row = mysqli_fetch_array($result)){
echo "<tr class='table_row'>";
echo " <td>" . $row['Data_cont'] . "</td>";
echo " <td>" . $row['Data_valuta'] . "</td>";
echo " <td>" . $row['Importo'] . "</td>";
echo " <td>" . $row['Divisa'] . "</td>";
echo " <td>" . $row['Causale'] . "</td>";
echo " <td>";
foreach ($categories as $value){
if ($value['ID'] == $row['Categoria']){
echo " <span class='label label-success'>";
echo "". $value['Descrizione'] ."";
echo "<input type='text' class='label label-success' id='categoria' name='categoria' value='". $value['Descrizione'] ."'/>";
echo "</span></td>";
}
}

In the end I've completely change the approach and now I'm building my table using ajax option in datatable.
In this way I'm able to retrieve all the data in the row using the same ajax option.

How to pass information through jQuery

I am attempting to pass information from the button within the column "actions" to the modal div, I call the modal using JS, However I am unsure about how to send information from the table over to the div. (Remember it has to be different information for every button as each button is in another row)
<?php
error_reporting(0);
$con = new mysqli("localhost","****","****","****");
if(mysqli_connect_errno()){
echo(mysqli_connect_error());
}
$cuser = $_COOKIE['c_user'];
$result = $con->query("SELECT * FROM calls");
echo"
<table class=\"table table-bordered responsive\">
<thead>
<tr>
<th width=\"5%\">#</th>
<th>Call Status</th>
<th>Player ID</th>
<th>Player Name</th>
<th width=\"33%\">Actions</th>
</tr>
</thead>
<tbody>";
while($row = $result->fetch_assoc()){
echo "<tr> ";
echo("<td>" . $row['id'] . "</td> ");
echo("<td>" . $row['status'] . "</td> ");
echo("<td>" . $row['pid'] . "</td> ");
echo "<td>" . $row['pname'] . "</td> ";
echo "<td> ";
if($row['status'] == 'Pending'){
echo "<a button type=\"button\" class=\"btn btn-warning\" href=\"calls.php?claim=true&callid=$row[id]\">Claim Call</button /a> ";
} else if($cuser == $row['claimedby']) {
echo "<a button type=\"button\" class=\"btn btn-danger\" href=\"calls.php?closecall=true&callid=$row[id]\">Close Call</button /a> ";
} else {
echo "<a button type=\"button\" class=\"btn btn-warning disabled\">Claimed</button /a> ";
}
echo "<a button type=\"button\" href=\"javascript:;\" onclick=\"jQuery('#modal-2').modal('show');\" class=\"btn btn-info\">Call Info</button /a> ";
echo "<a button type=\"button\" id = $row[id] href=\"javascript:;\" onclick=\"jQuery('#modal-1').modal('show');\" class=\"btn btn-success\">Server Info</button /a> ";
echo "<a button type=\"button\" class=\"btn btn-primary\">Join Server</button /a> ";
echo "</td> ";
}
echo "</tr>
</tbody>
</table>";
echo"<div class=\"modal fade\" id=\"modal-1\">
<div class=\"modal-dialog\" style=\"width: 50%\">
<div class=\"modal-content\">
<div class=\"modal-header\">
<button type=\"button\" class=\"close\" data-dismiss=\"modal\" aria-hidden=\"true\">×</button>
<h4 class=\"modal-title\">Call Info</h4>
</div>
<div class=\"modal-body\" id=\"serverHandle\">
</div>
<div class=\"modal-footer\">
<button type=\"button\" class=\"btn btn-default\" data-dismiss=\"modal\">Close</button>
</div>
</div>
</div>
</div>";
?>

Do you want to send any kind of information from Buttons to Modal DIV when somebody clicks on those buttons ? If that you want then you can add one custom attribute to your button like this <button info='my-info' id=''>Click</button> then when someone click on that button you can extract the value from that attribute by using JavaScript this & place that to the MODAL window by using any ID from Modal DIV.

You can add something like this to your button along with a click event.
data-value="<?php echo $Something->SomeValue;?>"
Then, when the click event gets triggered, you can get the value like this:
$(this).data("value");
you can use various data-[tag] to pass multiple pieces of information.
Or as an alternative, add this to each button:
onclick='someFunction("<?php echo $Something->SomeValue;?>")';

Checking if checkboxes in PHP are checked using javascript

echo '<div class="col-lg-10 col-lg-offset-1 panel">' . "<table id='data' class='table'>
<tr>
<th></th>
<th>Document No</th>
<th>AWB NO</th>
<th>Order Id</th>
<th>Forms</th>
<th>Extras</th>
</tr>";
foreach ($cancel as $key => $value)
{
echo "<tr>";
echo "<td>" . "<input type='checkbox' name='name1' id='checkit$checkitCounter' />" . "</td>";
echo "<td>" . $value[$d] . "</td>";
echo "<td>" . $value[$a] . "</td>";
echo "<td>" . $value[$o] . "</td>";
echo "<td>" . $value[$f] . "</td>";
echo "<td>" . $value[$e] . "</td>";
echo "</tr>";
}
echo "</table></div>";
This above table is generated using php echo with checkbox generated every iteration.
<div style="padding-left:600px;">
<a href='#' class='btn btn-primary btn-md' id='button' style="margin-right:1000px;" onclick='checkit()'
role='button'>Continue..</a>
</div>
The above button is supposed to run a javascript function given below:
function checkit {
var x = document.getElementById("checkit").checked;
if (x == false) {
alert('All items are not removed,pls remove and continue');
}
else {
window.location = "tst.php";
}
}
The above JavaScript doesn't seem to be functioning properly as even though i have checked none of the boxes it just stays on the same page.

Example:
<div style="padding-left:600px;"> <a href='#' class='btn btn-primary btn-md' id='button' style="margin-right:1000px;" onclick='checkit()' role='button'>Continue..</a>
</div>
<input type='checkbox' name='name1' class='checkit' />
<input type='checkbox' name='name1' class='checkit' />
<input type='checkbox' name='name1' class='checkit' />
<input type='checkbox' name='name1' class='checkit' />
<input type='checkbox' name='name1' class='checkit' />
<input type='checkbox' name='name1' class='checkit' />
And js:
function checkit() {
var boxes = document.querySelectorAll(".checkit");
arr = [];
for (i = 0; i < boxes.length; i++) {
arr.push(boxes[i]);
}
console.log(arr);
function is_checked(val) {
return val.checked == true;
}
checked = arr.filter(is_checked);
console.log(checked);
if (checked.length != boxes.length) {
alert('All items are not removed,pls remove and continue');
} else {
window.location = "tst.php";
}
}

I have made a light version of your code and the rest is left to your development logic.
You have had a lot small problems in your code, like function in JavaScript needed (), the usage of single and double quotes, missing call the JavaScript function etc.
I have created a dummy array for test, but again you could do what you like to achieve your code.
Here is the working solution:
<?php
$cancel = ["checkBox1", "checkBox2", "checkBox3"];
echo "<div><table id='data' class='table'>
<tr>
<th></th>
<th>Document No</th>
</tr>";
foreach ($cancel as $value)
{
echo "<tr>";
echo "<td><input type='checkbox' name='name1' id='$value' onchange='checkIt(\"$value\");' /></td>";
echo "<td>" . $value . "</td>";
echo "</tr>";
}
echo "</table></div>";
?>
<script>
function checkIt(checkBoxId) {
var x = document.getElementById(checkBoxId).checked;
console.log("x" + checkBoxId + " is " + x);
}
</script>
You can see in your console the results of your checkbox.

Expand/Collapse table row Javascript works wrongly

I'm using this code to expand database table row to reveal more information about the item, but it does exactly the opposite.
$("td span.expand").click(function() {
$(this).parents("tr.main").nextUntil("tr.main"). toggle();
});
When I open the table all rows that must be hidden are being shown and if I click on any main row it will hide that rows.
How to invert this?
Here's part of code I use for table (I know, it's messy):
echo '<table border="1" class="tabula">
<tr class="main">
<th width="30px">Nr.</th>
<th width="75px">Mašīnas numurs</th>
<th width="75px">Reģistrācijas numurs</th>
<th width="75px">Marka / Modelis</th>
<th width="75px">ID</th>
</tr>';
//Ieraksta datus tabulā
while($row = mysql_fetch_array($query))
{
echo "<tr class='main'>";
echo "<td width='30px'>" . $row['nr'] . "</td>";
echo "<td width='75px'>" . $row['numurs'] . "</td>";
echo "<td width='75px'><span class='expand'>" . $row['regnr'] . "</span></td>";
echo "<td>" . $row['modelis'] . "</td>";
echo "<td>" . $row['apzim'] . "</td>";
echo "</tr>";
echo "<tr class='hidden'>";
echo "<td>text</td>";
echo "<td>text</td>";
echo "<td>text</td>";
echo "</tr>";
}
echo "</table>";
echo "<br>";

Try using CSS in your file and include the following:
<style>
.expand
{
display:none;
}
</style>
I use a jQuery-based toggle script, and that's what I used when I had a similar problem such as this.
You may need to use .hidden { display:none; } instead.

Javascript popup only showing the last result in PHP query

I have the following block of code and I'm not sure how to do what I'm wanting to do.
In essence I'm wanting the javascript popup to display that row's value, but (obviously) it's only showing the final row of data as the popup isn't set for each row but rather calls the variable when clicked.
Any help would be appreciated!
<?php
$result = mysql_query("SELECT hr_overtime.overtime_id, hr_user.name, hr_overtime.overtime_date, hr_overtime.overtime_type, hr_overtime.overtime_from, hr_overtime.overtime_to, hr_overtime.overtime_amount, hr_overtime.details
FROM hr_overtime
inner join hr_user
on hr_user.user_id = hr_overtime.user_id
where hr_overtime.overtime_status = 'Pending' order by hr_overtime.overtime_date ASC");
echo "
<table border='0'>
<tr>
<th class='tablecell_header'>Consultant</th>
<th class='tablecell_header'>Date</th>
<th class='tablecell_header'>Type</th>
<th class='tablecell_header'>From</th>
<th class='tablecell_header'>To</th>
<th class='tablecell_header'>Amount</th>
<th> </th>
<th> </th>
<th> </th>
</tr>";
while($row = mysql_fetch_array($result))
{
$work = $row['details'];
echo "<tr>";
echo "<td class='tablecell'>" . $row['name'] . "</td>";
echo "<td class='tablecell'>" . $row['overtime_date'] . "</td>";
echo "<td class='tablecell'>" . $row['overtime_type'] . "</td>";
echo "<td class='tablecell'>" . $row['overtime_from'] . "</td>";
echo "<td class='tablecell'>" . $row['overtime_to'] . "</td>";
echo "<td class='tablecell'>" . $row['overtime_amount'] . "</td>";?>
<td class='tablecell'> <button onclick="myFunction()">Show work</button> </td><script>
function myFunction()
{
alert("<?php echo $work;?>");
}
</script>
<?php
echo "<td valign='middle'><form action='manager_overtime_approve.php' method='post'>
<input name='approve_id' type='hidden' value='" . $row['overtime_id'] . "' />
<input type='submit' value='APPROVE' id='edit' />
</form></td>";
echo "<td valign='middle'><form action='manager_overtime_reject.php' method='post'>
<input name='cancel_id' type='hidden' value='" . $row['overtime_id'] . "' />
<input type='submit' value='REJECT' id='edit' />
</form></td>";
echo "</tr>";
}
echo "</table>";
?>

There is no need for a separate function which you are using incorrectly. You can simply use an inline alert for this:
<td class='tablecell'> <button onclick="alert('<?php echo $work;?>');">Show work</button>

You can't insert the declaration of myFunction() inside your foreach loop, that way you are overriding for each entry the behaviour showed thus it's only working for the last row.
one fast solution would be to insert the whole $work variable as an argument of your onclick function eg.
<td class='tablecell'> <button onclick="myFunction('<?php echo $work ?>')">Show work</button>
and then outside of the foreach loop you can define myFunction such as:
function myFunction(details){
alert(details)
}

I think, in result HTML you have a multiple definitions of myFunction() and javascript uses only last one. You can use a HTML tag attributes to show right information.

try this
$work .= $row['details'];
and set javascript out of the loop
good luck

That's because myFunction is a Javascript function, which is defined once and doesn not share the same scope as PHP. So $work hold just the last value.
I'd suggest something like this:
echo "<tr data-detail-value='$work'>";
...
<td class='tablecell'> <button onclick="myFunction(this)">Show work</button>
...
function myFunction(btn) {
alert(btn.parentNode.parentNode.getAttribute("data-detail-value"));
}
