Answer 1

AS mentioned in Comments try this
"SELECT * FROM tblguest WHERE MONTH(checkin) =".$_POST['month'];

Answer 2

You should write this. This might solve your problem
$stmt = $db_con->prepare("SELECT * FROM tblguest WHERE MONTH(checkin) = '".$_POST['month']."' ");
$stmt->execute();
while($row=$stmt->fetch(PDO::FETCH_ASSOC))
{
?>
<tr>
<td><?php echo $row['fname']; ?></td>
<td><?php echo $row['lname']; ?></td>
<td><?php echo $row['checkin']; ?></td>
<td><?php echo $row['checkout']; ?></td>
<td><?php echo $row['rrate']; ?></td> //data
<td><?php echo $row['reservefee']; ?></td>
<td><?php echo $row['datepaid']; ?></td>
<td><?php echo $row['modepayment']; ?></td>
<td><?php echo $row['stats']; ?></td>
<td align="center">
<a id="<?php echo $row['fname']." ".$row['lname']; ?>" class="edit-link" href="#" title="Edit">
<img src="edit.png" width="20px" />
</a></td>
<td align="center"><a id="<?php echo $row['fname']." ".$row['lname']; ?>" class="delete-link" href="#" title="Delete">
<img src="delete.png" width="20px" />
</a></td>
</tr>
<?php
}
?>
</tbody>
