Efter INSERT få fram Id?

int mysql_insert_id ( [resource link_identifier])

mysql_insert_id() returns the ID generated for an AUTO_INCREMENT column by the previous INSERT query using the given link_identifier. If link_identifier isn't specified, the last opened link is assumed.

mysql_insert_id() returns 0 if the previous query does not generate an AUTO_INCREMENT value. If you need to save the value for later, be sure to call mysql_insert_id() immediately after the query that generates the value.

Fel forum btw

Denna går också o använda

Also note that the value of the SQL LAST_INSERT_ID() function always contains the most recently generated AUTO_INCREMENT value, and is not reset between queries because the value of that function is maintained in the server.

RTFM?
Tackar

ett annat script...

jag använder mig av detta när jag vill veta id:t från senaste posten...

$open = mysql_connect ("localhost", "$dbu","$dbp");
$sql = "SELECT id FROM tabell order by id desc limit 1";
$result = mysql_db_query("databasnamn","$sql");

while($row=mysql_fetch_array($result)){
$senaste_id = $row['id'];
}
