php - Having trouble getting the last id in MySQL -

-

i'm trying last id added database using mysql_insert_id doesn't work. error is:

mysql_insert_id() [function.mysql-insert-id]: can't connect local mysql server through socket '/var/tmp/mysql.sock' (2) in /proj/co639/assessment2/nicp3/public_html/book_create.php on line 46

warning: mysql_insert_id() [function.mysql-insert-id]: link server not established in /proj/co639/assessment2/nicp3/public_html/book_create.php on line 46

i've done connection this:

$handle = new pdo( 'mysql:host=;dbname=', '', '');

what issue?

you looking this:

$handle->begintransaction(); // here execute query $handle->commit(); $id = $handle->lasinsertid();

your code won't work because mix 2 different classes.

more information can found here: http://php.net/manual/en/pdo.lastinsertid.php
