Hmmmmmmmmmmmmmm.... I'd first put a "or die" clause onto
the clause...
$updated = mysql_query($update_query);
..like this because I suspect that it's dying before it can
execute ...
$updated = mysql_query($update_query) or die ("Invalid SQL
[$update_query]");
... what I would currently suspect to find would be the
'times_visited' column is numeric instead of alphanumeric.
When the update happens, it chokes at having the value your
setting for 'times_visited' quoted with apostrophes....
Originally, it looks like this...
$update_query = "update guestbook set last_access=now(),
times_visited='$times' where guest_id='$g_id'";
.. if "times_visited" is numeric, I'd change it to ...
$update_query = " update guestbook ";
$update_query .= " set last_access=now(), ";
$update_query .= " times_visited = $times ";
$update query .= " where guest_id='$g_id'";
As another note, if the column "last_accessed" is of a "timestamp"
data type, then you can do the following update to cause it to
automagically update with a "now()" value being put into it as well.
$update_query = " update guestbook ";
$update_query .= " set times_visited = $times ";
$update query .= " where guest_id='$g_id'";
This works because "timestamp" column types that aren't mentioned
directly in the update/insert query types are automatically set to
the current system time (which would be a now()).
