I just wrote a function, which returns the last inserted auto-incrementing id:
<?php
$r = mysql_query("INSERT INTO
my_table (...) VALUES (...)");
$id = last_insert_id( $r );
if( false === $id) echo 'error';
function last_insert_id_after_single_insert( $r ){
if( true !== $r) return false;
if( 1 !== mysql_affected_rows()) return false;
$r = mysql_query("SELECT LAST_INSERT_ID() AS id"); // INSERT returns
true/false
if( 1 !== mysql_num_rows( $r )) return false; // false or other num
$r = mysql_fetch_array( $r );
if( false === $r) return false;
return $r['id'];
}
?>
