i want to select the most recent entry from a table and see if that entry is exactly the same as the one the user is trying to enter. How do I do a query to "select * from the most recent entry of 'posting'"?
$query="Select * FROM
//confused here
(SELECT * FROM posting ORDER
BY date_added DESC)
WHERE user_id='{$_SESSION['user_id']}'
AND title='$title'
AND price='$price'
AND city='$city'
AND state='$state'
AND detail='$detail'
";
$data = mysqli_query($dbc, $query);
$row = mysqli_fetch_array($data);
if(mysqli_num_rows($data)>0)
{
echo "You already posted this ad. Most likely caused
by refreshing too many times.";
echo "<br>";
$linkposting_id=$row['posting_id'];
echo "See the <a href='ad.php?posting_id=$linkposting_id'>Ad</a>";
}
else
{
...insert into the dbc
}
