Get last insert id after a prepared insert with PDO
From the Manual:
Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver. For example, PDO_PGSQL() requires you to specify the name of a sequence object for the name parameter.
It should be something like:
return $db->lastInsertId('yourIdColumn');[EDIT] Update link to doc
Previous answers are not very clear (PDO doc too)
In postgreSQL, sequences are created when you are using the SERIAL data type.
CREATE TABLE ingredients ( id SERIAL PRIMARY KEY, name varchar(255) NOT NULL,);So the sequence name will be ingredients_id_seq
$db->lastInsertId('ingredients_id_seq');
