making two tables depending if they have 0 or 1 - php

Question

essentially I want to have two tables one with everyone with Confirmed = 1 and the other with Confirmed = 0.
I have this sql query at the moment
$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE $row[Confirmed] = 1");
but I keep getting
Notice: Undefined variable: row in C:\xampp\htdocs\test.php on line 19
Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in
rest of the code for that page
echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";
while($row = mysqli_fetch_array($result) )
{ ?>
<tr>
<td> <?php echo $row['tbl_mem_id']; ?> </td>
<td> <?php echo $row['BookID']; ?> </td>
<td> <?php echo $row['date']; ?> </td>
<td> <?php echo $row['time']; ?> </td>
<td> <?php echo $row['Confirmed']; ?> </td>
<td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
<td>
<?php
if ($row['Confirmed'] == 0) { ?>
<a href=confirm.php?BookID=<?php echo $row['BookID']; ?> </a> Confirm </td> <?php } else { ?>
<a href=deny.php?BookID=<?php echo $row['BookID']; ?> </a> Deny </td> <?php
} ?>
</tr> <?php
} ?>
</table>

Answer 1

Are you really trying to put the value in $row['Confirmed'] in the query, or are you just trying to query a field named Confirmed? if its the latter try this:
$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed= 1");
but since also you seem to differentiate the table in php with if ($row['Confirmed'] == 0) you probably need to get all data in one query with this:
$result = mysqli_query($con,"SELECT * FROM tbl_booking");
this won't give you 2 tables as you initially asked for though.
you can create 2 html tables with this:
<?php
$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed = 1");
echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";
while($row = mysqli_fetch_array($result) )
{ ?>
<tr>
<td> <?php echo $row['tbl_mem_id']; ?> </td>
<td> <?php echo $row['BookID']; ?> </td>
<td> <?php echo $row['date']; ?> </td>
<td> <?php echo $row['time']; ?> </td>
<td> <?php echo $row['Confirmed']; ?> </td>
<td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
<td>
<a href=deny.php?BookID=<?php echo $row['BookID']; ?> </a> Deny </td>
</tr> <?php
} ?>
</table>
<?php
echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";
$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed = 0 ");
while($row = mysqli_fetch_array($result) )
{ ?>
<tr>
<td> <?php echo $row['tbl_mem_id']; ?> </td>
<td> <?php echo $row['BookID']; ?> </td>
<td> <?php echo $row['date']; ?> </td>
<td> <?php echo $row['time']; ?> </td>
<td> <?php echo $row['Confirmed']; ?> </td>
<td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
<td>
<a href=confirm.php?BookID=<?php echo $row['BookID']; ?> </a> Confirm </td>
</tr> <?php
} ?>
</table>
