Question

How can I check to see if an item has a lower id than of another item on the same table?

I already have this:

while ($row = $result->fetch_array()) {
if ($row[name] == $myusername) {
    $mysqli->query("DELETE FROM users WHERE name='$myusername' AND password='$mypassword'");
} }

But this is useless as it deletes the account as soon as it’s made.

Answer 1

You could add it in the WHERE clause

DELETE FROM users WHERE name='$myusername' AND password='$mypassword' AND users.id < [someOtheID]

You need to give a schema if you want a better answer
