PHP - Create New Line Of Dynamically Populated Content From Button

<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>

<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>

<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
	if(!empty($_POST['fSelected']))
	{
		$chosen = $_POST['fSelected'];
		foreach ($chosen as $item)
			echo "aID selected: $item </br>";
		$delimit = implode(", ", $chosen);
		print_r($delimit);
	}

}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
	$aTitle[] = $row[ 'name' ];
}
}
?>

<table>
	
		<?php if(isset($delimit)) { 
		$c=0; foreach($aTitle as $item) {?>
		<tr>
		<td>
			<?php echo $aTitle[$c]; $c++;?>
		</td>
		</tr>
		<?php }}?>
</table>

In this report I want to create a line break and a Total line for each State.

 while ($row = odbc_fetch_array($result))
{
    echo "<tr><td>" .  $row['cmlstate']."</td>";
    echo "<td>" .  $row['cmlpostcode']."</td>";
    echo "<td>" .  $row['cmlcity']."</td>";
    echo "<td>" .  $row['ompSalesOrderID']."</td>";
    echo "<td>" .  $row['cmoName']."</td>";
    echo "<td>" .  number_format($row['UOMPVOLUMETOTAL'],2)."</td>";
    echo "<td>" .  number_format($row['UOMPTOTALBOXCOUNT'],0)."</td>";
    echo "<td>" .  $row['Hold']."</td></tr>"; 
    

I want to sum 'UOMPVOLUMETOTAL' for each state and create a line break between it and the next state.
    
}

I've been working on developing a CMS blog and now I'm trying to create a slideshow wit Bootstrap Carousel on the homepage to present the dynamic content (images + text) using the data from table 'posts'.

I tested this code, and it only presents one post. I mean, It's not possible to go to the next slide. I want to show all the posts on the slides.

*The DB connection is already on the includes. The connection was written on a small file called DB.php
