Using select option embeded in a table to dynamically change a user role to different roles via JQuery and AJAX

Im trying to dynamically allow the user to change a user role by using a select tag within a table which, when change triggers an event, record the changes in JQuery and send the changes to PHP via AJAX. From the image attached, the only select tag which fires an event is the one in the first row of the table shown. Any changes made to other rows does not fired an event as shown by one of the images with the console.log information. I am trying to allow whoever has the rights to change a specific user role by selecting the adajacent select option within the same table row which is send via AJAX to change the field in the database. I have posted this question before however Wesley Smith recommended I do a new post. Anyone please feel free to comment.

User Interface and Console log[enter image description here][1]
[User Interface][1]

Your selector selects all with the class urole, you just want to select the one that changed, since you're in the change handler for that element you can access it via the this keyword.
$('.urole').on('change',function (e){
e.preventDefault();
var val = this.value;
console.log(val);
console.log(e);
displayData(val);
});

how to get row value with ajax triggered by onchange dropdown?

I tried to update 1 row in table with ajax triggered by onchange dropdown, I succeed update data but it updating all data in my table.
so how I can get unique value (eg :User ID) to pass it from ajax to my php so i can update it only 1 row?
here's my code :
my table (transactions.php)
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>User ID</th>
<th>Pengirim</th>
<th>Jumlah Transfer</th>
<th>Berita Acara</th>
<th>Status</th>
<th>Rincian</th>
</tr>
</thead>
<tbody>
<?php
$query = mysqli_query($koneksi, "select * from konf_transf order by tanggal desc limit 7 ");
while($data1 = mysqli_fetch_array($query)){
?>
<tr>
<td>
<center><?php echo $data1['usr_id']; ?></center>
</td>
<td>
<center><?php echo $data1['nm_pengirim']; ?></center>
</td>
<td>
<center>Rp. <?php echo number_format($data1['jmlh_transf'],0,'','.'); ?>,-</center>
</td>
<td>
<center><?php echo $data1['berita_acara']; ?></center>
</td>
<td>
<center><?php echo $data1['status']; ?></center>
</td>
<td>
<center>
<select name="pilihstatus" id="pilihstatus" onchange="updatetransactions();">
<option value="Pilihan">Pilihan</option>
<option value="Sudah">Sudah</option>
<option value="Belum">Belum</option>
</select>
</center>
</td>
</tr>
<?php } ?>
</tbody>
</table>
and here my ajax
function updatetransactions(){
var id = $('select option:selected').val();
$.ajax({
type:"post",
url:"updatestatustransaksi.php",
data:"status="+id,
success:function(data){
alert('Successfully updated mysql database');
}
});
}
my updatestatustransaksi.php
<?php
require_once("koneksi.php");
session_start();
if (!isset($_SESSION['username'])) {
echo "<script>alert('You must register an account first, we will redirect you to register page !'); window.location = 'registuser.php'</script>";
}
$dataupd = $_POST["status"];
$query = mysqli_query($koneksi, "UPDATE `konf_transf` SET `status` = '$dataupd' WHERE `id` = '$penjualan_id'");
if ($query) {
echo "<script>alert('Update Success.'); window.location = 'transactions.php' </script>";
} else {
echo "<script>alert('Update Failure.'); window.location = 'transactions.php' </script>";
}

I assume that you update all of your rows in your database, with no WHERE condition. In your script, lets also get the corresponding id of that row in your database.
Lets assign first the id for each table row:
while($data1 = mysqli_fetch_array($query)){
?>
<tr id="<?=($data1['user_id'])?>">
Then, lets change how you trigger your javascript. Lets first change the <select> field:
<select name="pilihstatus" id="pilihstatus" class="pilihstatus">
Then, get the corresponding id using the script below:
$(".pilihstatus").change(function(){
var elem = $(this),
selecteditem = elem.val(),
id = elem.closest('tr').attr('id');
$.ajax({
type:"post",
url:"updatestatustransaksi.php",
data: {'status':selecteditem, 'id':id},
success:function(data){
alert('Successfully updated mysql database');
}
});
});
And on your updatestatustransaksi.php file (please use prepared statement):
$stmt = $koneksi->prepare("UPDATE `konf_transf` SET `status` = ? WHERE `id` = ?");
$stmt->bind_param("si", $_POST['selecteditem'], $_POST['id']);
$stmt->execute();
$stmt->close();

Try adding data_id attribute to select
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th>User ID</th>
<th>Pengirim</th>
<th>Jumlah Transfer</th>
<th>Berita Acara</th>
<th>Status</th>
<th>Rincian</th>
</tr>
</thead>
<tbody>
<?php
$query = mysqli_query($koneksi, "select * from konf_transf order by tanggal desc limit 7 ");
while($data1 = mysqli_fetch_array($query)){
?>
<tr>
<td>
<center><?php echo $data1['usr_id']; ?></center>
</td>
<td>
<center><?php echo $data1['nm_pengirim']; ?></center>
</td>
<td>
<center>Rp. <?php echo number_format($data1['jmlh_transf'],0,'','.'); ?>,-</center>
</td>
<td>
<center><?php echo $data1['berita_acara']; ?></center>
</td>
<td>
<center><?php echo $data1['status']; ?></center>
</td>
<td>
<center>
<select name="pilihstatus" id="pilihstatus" onchange="updatetransactions();" data_id='<?php echo $data1['usr_id']; ?>'>
<option value="Pilihan">Pilihan</option>
<option value="Sudah">Sudah</option>
<option value="Belum">Belum</option>
</select>
</center>
</td>
</tr>
<?php } ?>
</tbody>
</table>
and get that data_id value in your function
function updatetransactions(){
var status = $('select option:selected').text();
var status = $('select').attr('data_id');
var id = $('select option:selected').val();
$.ajax({
type:"post",
url:"updatestatustransaksi.php",
data:{'status'=status,'id'=id}
success:function(data){
alert('Successfully updated mysql database');
}
});
}
and at your updatestatustransaksi.php
<?php
require_once("koneksi.php");
session_start();
if (!isset($_SESSION['username'])) {
echo "<script>alert('You must register an account first, we will redirect you to register page !'); window.location = 'registuser.php'</script>";
}
$dataupd = $_POST["status"];
$id = $_POST["id"];
$query = mysqli_query($koneksi, "UPDATE `konf_transf` SET `status` = '$dataupd' WHERE `id` = '$id'");
if ($query) {
echo "<script>alert('Update Success.'); window.location = 'transactions.php' </script>";
} else {
echo "<script>alert('Update Failure.'); window.location = 'transactions.php' </script>";
}

Have you initialised $penjualan_id? I think you need to initialise it like this:
$penjualan_id=$_SESSION['user_id']

No popup window appear with paginated table

I have paginated table and input field. I want to allow user to create new process. Created table allow user to view already existed processes.
hmtl code:
<div class="inner">
<center><table class="paginated">
<?php
$result = getProcessData();
if (mysqli_num_rows($result) > 0)
{
echo '
<thead>
<tr>
<th>Process</th>
<th>Created By</th>
</tr>
</thead>';
}
$count = 0;
if (mysqli_num_rows($result) > 0)
while($row = mysqli_fetch_array($result))
{
$process = $row['theme_name'];
$createdBy = $row['createby'];
echo '
<tbody>
<tr valign="top">
<td>' .$process. '</td>
<td>' .$createdBy. '</td>
</tr>
</tbody>';
$count++;
}
?>
</table></center>
<form id="reguserform" method="post" action="process.php#err" style="margin-top:40px;">
<?php
$res = verifyFormFields();
?>
<!-- Username field -->
<input type="text" class="input name" placeholder="Process name (required)" name="process" required/>
<!--<label class="tooll tool1">- No special Characters except _<br>- Character Limit: 4 to 20<br>- Username must be Unique</label>-->
<center><input type="submit" class="button small" name="submit" value="Create Process"/></center>
<div id="registerModal" class="reveal-modal small" data-reveal aria-labelledby="modalTitle" aria-hidden="true" role="dialog" data-options="close_on_background_click:false">
<h2 id="modalTitle">Success!</h2>
<div>
<div id="testRegister" style="font-weight: 400;font-size: 1.5em; font-family: 'Raleway', Arial, sans-serif;"></div>
<div class="right">
Ok
</div>
</div>
</div>
<?php
if($count == 1)
{
if($res=="")
{
registerProcess();
echo"<script>document.getElementById('testRegister').innerHTML=registerStr;callShowAlert();</script>";
}
else{
echo "
<a style='color:red';>
$res
</a>
";
}
}
?>
</form>
</div>
I validate the field and the inserting process into database:
function registerProcess(){
$con = mysqli_connect(DATABASE_HOST, DATABASE_USER, DATABASE_PASSWORD, DATABASE_NAME);
global $process;
// To protect MySQL injection (more detail about MySQL injection)
$process = cleanInputData($process);
$process = mysqli_real_escape_string($con, $process);
//query result
$result = insertNewProcess(NULL,$process,$_SESSION['login_user'],1);
// Check result
if (!$result) {
$msg2= "Process is already added. You cannot add same process twice!";
echo $msg2;
die('Invalid queryyyy: ' . mysqli_error($con));
}
// the message
$msg = "Process is added!";
// use wordwrap() if lines are longer than 70 characters
echo "<script>var registerStr = 'Process Is Added';</script>";
//echo "<meta http-equiv='refresh' content='0'>";
}
function verifyFormFields(){
global $process;
if(empty($process)){
return "<p id ='err'>Please Input Process</p>";
}
else return "";
}
Also I use javascript to call pop up window and make table paginated:
<script type="text/javascript">
(function() {
$(document).foundation();
});
function callShowAlert()
{
$('#registerModal').foundation('reveal', 'open');
}
function popUpNo()
{
$('#registerModal').foundation('reveal', 'close');
location.href = 'process.php';
}
var testVal = 0;
</script>
<script>
$(document).ready(function() {
$('table.paginated').each(function() {
var currentPage = 0;
var numPerPage = 5;
var $table = $(this);
$table.bind('repaginate', function() {
$table.find('tbody tr').hide().slice(currentPage * numPerPage, (currentPage + 1) * numPerPage).show();
});
$table.trigger('repaginate');
var numRows = $table.find('tbody tr').length;
var numPages = Math.ceil(numRows / numPerPage);
var $pager = $('<div class="pager"></div>');
for (var page = 0; page < numPages; page++) {
$('<span class="page-number"></span>').text(page + 1).bind('click', {
newPage: page
}, function(event) {
currentPage = event.data['newPage'];
$table.trigger('repaginate');
$(this).addClass('active').siblings().removeClass('active');
}).appendTo($pager).addClass('clickable');
}
$pager.insertBefore($table).find('span.page-number:first').addClass('active');
});
} );
</script>
it works perfect, I got popup window and system inserts record to database but only if there is only input field and submit button. When I put table it doesnt work. System does not reload and not insert record into database. Why?

So I solved this problem by simply putting table after form:
<div class="inner">
<form id="reguserform" method="post" action="process.php#err" style="margin-top:40px;">
<?php
$res = verifyFormFields();
?>
<!-- Username field -->
<input type="text" class="input name" placeholder="Process name (required)" name="process" required/>
<!--<label class="tooll tool1">- No special Characters except _<br>- Character Limit: 4 to 20<br>- Username must be Unique</label>-->
<center><input type="submit" class="button small" name="submit" value="Create Process"/></center>
<div id="registerModal" class="reveal-modal small" data-reveal aria-labelledby="modalTitle" aria-hidden="true" role="dialog" data-options="close_on_background_click:false">
<h2 id="modalTitle">Success!</h2>
<div>
<div id="testRegister" style="font-weight: 400;font-size: 1.5em; font-family: 'Raleway', Arial, sans-serif;"></div>
<div class="right">
Ok
</div>
</div>
</div>
<?php
if($count == 1)
{
if($res=="")
{
registerProcess();
echo"<script>document.getElementById('testRegister').innerHTML=registerStr;callShowAlert();</script>";
}
else{
echo "
<a style='color:red';>
$res
</a>
";
}
}
?>
</form>
<center><table class="paginated">
<?php
$result = getProcessData();
if (mysqli_num_rows($result) > 0)
{
echo '
<thead>
<tr>
<th>Process</th>
<th>Created By</th>
</tr>
</thead>';
}
$count = 0;
if (mysqli_num_rows($result) > 0)
while($row = mysqli_fetch_array($result))
{
$process = $row['theme_name'];
$createdBy = $row['createby'];
echo '
<tbody>
<tr valign="top">
<td>' .$process. '</td>
<td>' .$createdBy. '</td>
</tr>
</tbody>';
$count++;
}
?>
</table></center>
</div>
So as I got it, table cannot be updated before from.

The first query is working fine but 2nd query is not working.I have problem in this code below:-
if($comment_status =='Approve'){
$query = "UPDATE comments SET comment_status = 'approved' WHERE comment_id = $id";
}elseif($comment_status =='Unapprove'){
$query = "UPDATE comments SET comment_status = 'unapproved' WHERE comment_id = $id";
}

Case matters when comparing two strings to be the same
<option value="unapprove"
^^^
and
elseif($comment_status =='Unapprove'){
^^^

$id its a variable and you are putting there as string. Example:
<?php
$a = "Hello ";
$b = $a . "World!"; // "Hello World!"
$a = "Hello ";
$a .= "World!"; // "Hello World!"
?>
You must do the same.

HTML form doesn't capture all the checkboxes from Bootstrap responsive table

I have a table which displays results from my DB. In the last column I have checkboxes and by clicking submit button I am sending an array of account_id's to another php file. Everything works fine but the problem is that I am using a Bootstrap responsive table which can show 10-100 results on each page and the form only captures results on the current page. If I check boxes on different pages and switch between them, they still remain checked, though.
Here is my HTML:
<form action="compare.php" method="post">
<table class="table table-hover" id="dataTables-example">
<thead>
<tr>
<th style="text-align:center;">Account name</th>
<th style="text-align:center;">Address</th>
<th style="text-align:center;">Phone number</th>
<th style="text-align:center;">Website</th>
<th style="text-align:center;">Compare</th>
</tr>
</thead>
<tbody>
<?php
$result= mysql_query("select * from accounts order by account_name ASC" ) or die (mysql_error());
while ($row= mysql_fetch_array ($result) ){
?>
<tr>
<td class='clickable-row' data-href="select.php?id=<?php echo $row ['account_id'];?>"> <?php echo $row ['account_name'];?></td>
<td class='clickable-row' data-href="select.php?id=<?php echo $row ['account_id'];?>"> <?php echo $row ['address']; ?></td>
<td class='clickable-row' data-href="select.php?id=<?php echo $row ['account_id'];?>"> <?php echo $row ['phone_number']; ?></td>
<td class='clickable-row' data-href="select.php?id=<?php echo $row ['account_id'];?>"> <?php echo $row ['website']; ?></td>
<td> <input type="checkbox" name="checkboxvar[]" value="<?php echo $row ['account_id'];?>" /></td>
</tr>
<?php } ?>
</tbody>
</table>
<input class="btn btn-success" type="submit" value="Compare" id="submit">
</form>
I tried to use jQuery to see if it can capture the checkboxes from the whole table, but results is the same as trying an HTML form.
This script is supposed to capture them and make an alert:
<button id="bt1">Get</button>
<script>
$('#bt1').on('click', function () {
//Get checked checkboxes
var checkedCheckboxes = $("#dataTables-example :checkbox:checked"),
arr = [];
//For each checkbox
for (var i = 0; i < checkedCheckboxes.length; i++) {
//Get checkbox
var checkbox = $(checkedCheckboxes[i]);
//Get checkbox value
var checkboxValue = checkbox.val();
//Get siblings
var siblings = checkbox.parent().siblings();
//Get values of siblings
var value1 = $(siblings[0]).text();
var value2 = $(siblings[1]).text();
arr.push(checkboxValue + '-' + value1 + '/' + value2);
alert(checkboxValue + '-' + value1 + '/' + value2);
}
});
</script>
Is there a way to do it?

You can use Datatables object:
$('input', oTable.fnGetNodes()).each(function () {
if($(this).is('checked')){
console.log($(this).val());
}
});

Solved!
Include this script:
<script type="text/javascript" src="//cdn.datatables.net/plug-ins/f2c75b7247b/api/fnGetHiddenNodes.js"></script>
And this paste this function:
<script>
$(document).ready(function() {
oTable = $('#yourTableID').dataTable();
$('form').submit(function(){
$(oTable.fnGetHiddenNodes()).find('input:checked').appendTo(this);
});
});
</script>
All checkboxes are captured by clicking submit button.
