Hi Janice,

the error is given by this $_SESSION['last_id'], because is not set. Before running the query you can make sure the index is set by running:

if(TRUE === array_key_exists('last_id', $_SESSION))
{
    # execute query
}

Using my magical powers I've tried to telepathically deduce the error message you forgot to post and I think if you remove the ' around '".$_SESSION['last_id']."' it might solve your issue. Since your user_id column is defined as integer and those single quotes make it a string.

Also, although I think we've had that discussion before, I'd pray that Bobby Tables never signs up. You really shouldn't put $_POST variables directly into the query, but if you're set on using mysqli at least use prepared statements.

Edit: also do what cereal is saying.

Edit2: I should also learn to read titles, because you did post the error, sorry.
