Just check your data in the function fetchDataFromTable
something like
public function fetchDataFromTable()
{
$arrRows = $this->input->post('checkbox[]');
if (!empty($arrRows)) $this->db->where_in('id', $arrRows);
$query =$this->db->get('jc_meeting_expense');
...
}
and in your view just put in your id as value in your checkbox element
<td><input type="checkbox" id="checkbox" name="checkbox[]" value="<?php echo $row->id; ?>"></td>
That should pretty much do the job - assuming you did wrap your entire table in a form.

Please check the below code.

2nd data table don't show "no data available" message

I have 2 data tables:
Table 1
<table id="properties_list" class="table">
<thead>
<tr class="backend_tab_header">
<th>Status</th>
<th>Photo</th>
<th>Property ID</th>
<th>Address</th>
<th>Date Created</th>
<th>Owner</th>
</tr>
</thead>
<tbody>
<?php
foreach ($properties as $property)
{
?>
<tr>
<td><?php print $property["status"]; ?></td>
<td class="pic_prop_table"><img class="img-responsive" src="<?php print $property["url"]; ?>" ></td>
<td><?php print $property["prop_id"]; ?></td>
<td><?php print $property["address"]; ?></td>
<td><?php print $property["date_created"]; ?></td>
<td><?php print $property["first_name"]; ?> <?php print $property["last_name"]; ?></td>
</tr>
<?php
}
?>
</tbody>
</table>
Table 2
<table id="messages_list" class="table">
<thead>
<tr class="backend_tab_header">
<th>Property ID</th>
<th>Subject</th>
<th>Message</th>
<th>Received</th>
</tr>
</thead>
<tbody>
<?php
foreach ($properties as $property)
{
?>
<tr>
<td><?php print $messages["from_user"]; ?></td>
<td><?php print $messages["subject"]; ?></td>
<td><?php print $messages["message"]; ?></td>
<td><?php print $messages["date_sent"]; ?></td>
</tr>
<?php
}
?>
</tbody>
</table>
and to fill the arrays call my php functions on top of the page:
$properties = $auth_user->getPropertiesByUser($_SESSION['user_session']);
$messages = $auth_user->getMessages($_SESSION['user_session']);
The data tables are create with JS
jQuery(document).ready(function() {
jQuery('table#properties_list').DataTable( {
//ajax: '../ajax/data/arrays.txt',
scrollY: 200,
scrollCollapse: true,
paging: false
} );
jQuery('table#messages_list').DataTable( {
//ajax: '../ajax/data/arrays.txt',
scrollY: 200,
scrollCollapse: true,
paging: false
} );
});
My problem is that when the first array($properties) return empty the first table show the message "No data available in table" and also when both arrays($properties and $messages) return empty both tables show the message "No data available in table", but when $properties array return with info and $messages array return empty the 2nd table(messages)don't show the "No data available in table" and also creates as much <td> elements as <td> elements in the firs table(properties). Can anyone tell me what could be the cause of this behaviour?
Thanks in advance

probably it's because both of the for each in pop use the $properties. On second loop, it gets the $prperties of the first.
Try to set $properties = array() before getting the values or use another variable name.

Delete data from database using PHP & JavaScript

I am working on a PHP file. I am trying to make a table that shows the list of products from database. There will be also a button for deleting any product. I have used javascript for deleting products from database. I have written the code and could not find anything wrong. When I click delete button, it shows me the confirmation box, but does not delete the product. Here is the code:
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("grocery_shop",$con);
error_reporting(E_ALL^E_NOTICE);
session_start();
$sql = mysql_query("select * from products");
if($_GET['did']){
mysql_query("delete from products where product_id='$_GET[did]'");
header("Location: product.php");
}
?>
<table border="1px" style="width:100%">
<tr>
<th>Serial No</th>
<th>Product Name</th>
<th>Product Type</th>
<th>Quantity</th>
<th>Price</th>
<th>Delete Product</th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<?php
$i=1;
while ($u = mysql_fetch_array($sql)) {
?>
<tr>
<td><?php echo $i; ?></td>
<td><?php echo $u['product_name'];?></td>
<td><?php echo $u['product_type'];?></td>
<td><?php echo $u['quantity'];?></td>
<td><?php echo $u['price'];?></td>
<td><?php echo "Delete";?></td>
</tr>
<?php
$i++;
}
?>
<script>
function delproduct(id){
var msg = confirm("Are you sure you want to delete this product?");
if (msg) {
window.location = "product.php?did="+product_id;
}
}
</script>
</table>

The problem is in your javascript, the product_id doesn't exist
if (msg) {
window.location = "product.php?did="+id;
}
For debugging purposes try to replace this with your code and let us know the error message you get.
if($_GET['did']){
mysql_query("delete from products where product_id='".$_GET['did']."'");
echo "delete from products where product_id='".$_GET['did']."'";
echo mysql_errno() . ": " . mysql_error() ;
die();
//header("Location: product.php");
}
additionally also try to run the query without the single quotes, i am assuming product_id is an integer.
so mysql_query("delete from products where product_id=".$_GET['did']);

You forgot the '' around did in $_GET[did]:
mysql_query("delete from products where product_id='{$_GET['did']}'");
Also, as #chris85 noted, is not a good idea to use $_GET or $_POST directly, remember to sanitize these values before using it in a query.
$did = filter_input(INPUT_GET, 'did', FILTER_SANITIZE_NUMBER_INT);
mysql_query("delete from products where product_id={$did}");

<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("grocery_shop",$con);
error_reporting(E_ALL^E_NOTICE);
session_start();
$sql = mysql_query("select * from products");
if($_GET['did']){
mysql_query("delete from products where product_id='$_GET[did]'");
header("Location: product.php");
}
?>
<table border="1px" style="width:100%">
<tr>
<th>Serial No</th>
<th>Product Name</th>
<th>Product Type</th>
<th>Quantity</th>
<th>Price</th>
<th>Delete Product</th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<?php
$i=1;
while ($u = mysql_fetch_array($sql)) {
?>
<tr>
<td><?php echo $i; ?></td>
<td><?php echo $u['product_name'];?></td>
<td><?php echo $u['product_type'];?></td>
<td><?php echo $u['quantity'];?></td>
<td><?php echo $u['price'];?></td>
<td><?php echo "Delete";?></td>
</tr>
<?php
$i++;
}
?>
<script>
function delproduct(id){
var product_id = id;
var msg = confirm("Are you sure you want to delete this product?");
if (msg) {
window.location = "product.php?did="+product_id;
}
}
</script>
</table>

You should try: delproduct($u[product_id]) instead of delproduct(id=$u[product_id])
mysql_query("delete from products where product_id='".$_GET['did']."'");
while ($u = mysql_fetch_array($sql)) {
?>
<tr>
<td><?php echo $i; ?></td>
<td><?php echo $u['product_name'];?></td>
<td><?php echo $u['product_type'];?></td>
<td><?php echo $u['quantity'];?></td>
<td><?php echo $u['price'];?></td>
<td><?php echo "Delete";?></td>
</tr>
<?php
$i++;
}

Bootstrap popover not working in while loop

I'm trying to use the popover element from bootstrap's framework for Javascript/jQuery and it only works with the first one in the while loop. How can I make it work for all of them?
Why is this? Been trying to figure this out for a bit...
<?php
require 'include.php';
session_start();
$selectBets = $dbc->query("SELECT * FROM `bets` ORDER BY `bid` DESC LIMIT 10");
?>
<style type="text/css">
#hash_text {
font-size: 3.8px;
}
</style>
<table class="table table-striped table-bordered table-hover">
<thead>
<tr>
<th>Bet Number</th>
<th>Amount</th>
<th>Send Address</th>
<th>Time Created</th>
<th>Time Expires</th>
<th>Chance to Win</th>
<th>Payout Multiplier</th>
<th>Final Profit</th>
<th>Server Hash</th>
</tr>
</thead>
<tbody>
<?php while($BetsArray = $selectBets->fetch()) { ?>
<tr>
<td><?php echo $BetsArray['bid']; ?></td>
<td><?php echo $BetsArray['amount']; ?></td>
<td><?php echo $BetsArray['deposit_address']; ?></td>
<td><?php echo date('m/d/Y - H:i:s', $BetsArray['time_created']); ?></td>
<td><?php echo date('m/d/Y - H:i:s', $BetsArray['time_expires']); ?></td>
<td><?php echo $BetsArray['win_chance']; ?></td>
<td><?php echo $BetsArray['multiplier']; ?></td>
<td><?php echo $BetsArray['profit']; ?></td>
<td><a id="hash" data-container="body" data-toggle="popover" data-placement="right">Click here for Server Hash</a></td>
</tr>
<?php } ?>
</tbody>
</table>
<script type="text/javascript">
$(function() {
$('#hash').popover({
html: true,
placement: 'right',
content: '<?php echo '<span id="hash_text">' . hash('sha512', $BetsArray['number'] . '-' . $_SESSION['client_seed']) . '</span>'; ?>'
});
});
</script>

You are creating the popover element by duplicating the ids. Change it to class and see it working.
<a id="hash" data-container="body" data-toggle="popover" data-placement="right">Click here for Server Hash</a>
When you bind to the popover using the id selector $('#hash') it will select only the first element with id that appears in DOM and hence the behavior that you are seeing.
If you want to place a quick fix then you can use attribute selector to select the id like this.
$('[id=hash]').popover({
html: true,
placement: 'right',
content: '<?php echo '<span id="hash_text">' . hash('sha512', $BetsArray['number'] . '-' . $_SESSION['client_seed']) . '</span>'; ?>'
});
But never ever do that
