为什么bindvalue没有插入表？

Question

I have these query:

$sql="insert into m_ruangan (RG_ID,RG_Nama,RG_Kapasitas,RG_Keterangan,RG_AktifYN,RG_UpdateID,RG_UpdateTime) ".
        "values (:field1,:field2,:field3,:field4,:field5,:field6,:field7); ";

$stmt->bindValue(':field1', $result['RG_ID'], PDO::PARAM_INT);
$stmt->bindValue(':field2', $result['RG_Nama'], PDO::PARAM_STR);
$stmt->bindValue(':field3', $result['RG_Kapasitas'], PDO::PARAM_INT);
$stmt->bindValue(':field4', $result['RG_Keterangan'], PDO::PARAM_STR);
$stmt->bindValue(':field5', $result['RG_AktifYN'], PDO::PARAM_STR);
$stmt->bindValue(':field6', $result['RG_UpdateID'], PDO::PARAM_STR);
$stmt->bindValue(':field7', $result['RG_UpdateTime'], PDO::PARAM_STR);

$stmt =$m_f->cdb->prepare($sql);
$stmt->execute();

When I run it it show no error but the value will not inserted in the table. I'm using the looping for inserting

Any idea why it goes wrong?

Answer 1

You need to prepare your sql statement prior to bindValue,

$stmt =$m_f->cdb->prepare($sql);
$stmt->bindValue(':field1', $result['RG_ID'], PDO::PARAM_INT);
$stmt->bindValue(':field2', $result['RG_Nama'], PDO::PARAM_STR);
.........          
$stmt->execute();
