what does this line of ext_user_profile.php?

$this->profile_id = (empty($_SESSION['is_rec'])) ? mysql_insert_id() : $ident; 

Coult you explain  detaily  what this line does?

thanks,
tom

ok, it must be the same as:
x <x1 ? y : z
and it's the same as
if (x < x1 )
y
else
z

:-)

thats short for if then else

ok, and what for a new iprofile_id needs to be set?

sorry Tom, I can't follow you, please provide clear questions and code examples here

and don't mess with the class files!

I would like to understand the concept of how the user and the user row is identified. It seems to me that all this vars (id, users_id, session id, ident) are responsible for that but I have'nt got it until now.

Here is some code:
function save_profile_date($ident = "", $lang = "", ...) {

if (!empty($ident)) {

$sql = sprintf("UPDATE ...  $this->ins_string($ident, "int"), $_SESSION['user_id']);

} else {

$sql = sprintf("INSERT INTO %s (id, users_id, language, ..., NOW())",

..., $_SESSION['user_id'], $this->ins_string($lang), ...));

}

if (mysql_query($sql) or die (mysql_error())) {

$this->profile_id = (empty($_SESSION['is_rec'])) ? mysql_insert_id() : $ident;

...

}

}

function get_profile_data() {

$this->get_user_info();

$sql = sprintf("SELECT id, language, ... FROM %s WHERE users_id = %d", ... PROFILE_TABLE, $this->id);

$result = mysql_query($sql) or die (mysql_error());

if (mysql_num_rows($result) == 0) {

$this->the_msg = $this->extra_text(1);

return false;

} else {

$_SESSION['is_rec'] = true;

while ($obj = mysql_fetch_object($result)) {

$this->profile_id = $obj->id;

The var $ident seems to decide if an update or an insert record is processed, right?

But how is the user and the responsible table row identified?
