PSQL - INSERT has more expressions than target columns - php

Question

when I try to insert something to my PSQL DB i get this error:
SQLSTATE[42601]: Syntax error: 7 ERROR: INSERT has more expressions
than target columns LINE 1: ...acturer, model, submodel) VALUES($1,
$2, $3, $4, $4, $5, $6) ^
My query is displayed below, to avoid that its somehow data problem I just insert number strings. So this looks really wired for me.
Query:
public function insertToPsql($manufacturer_code, $main_type, $subtype_code, $manufacturer, $model, $submodel)
{
try {
//$con = new PDO( PSQL_DB_HOST, PSQL_DB_HOST, PSQL_DB_HOST );
$con = new PDO("pgsql:dbname=audahistory;host=localhost", "postgres", "");
$con->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sql = "INSERT INTO car_type(manufacturer_code, main_type, subtype_code, manufacturer, model, submodel) VALUES(:manufacturer_code, :main_type, :subtype_code, :manufacturer, :model, :submodel)";
$stmt = $con->prepare( $sql );
$stmt->bindValue( 'manufacturer_code', "1", PDO::PARAM_STR );
$stmt->bindValue( 'main_type', "2", PDO::PARAM_STR );
$stmt->bindValue( 'subtype_code', "3", PDO::PARAM_STR );
$stmt->bindValue( 'manufacturer', "4", PDO::PARAM_STR );
$stmt->bindValue( 'model', "5", PDO::PARAM_STR );
$stmt->bindValue( 'submodel', "6", PDO::PARAM_STR );
$stmt->execute();
}
catch( PDOException $e ) {
echo $e->getMessage();
exit;
}
}
Any idea where cna be a problem?
Thanks for advise
