error: 'Invalid parameter number: parameter was not defined' when using an array to INSERT in PDO

Question

I\'m trying to insert in array that looks like:

$prices = array(array(\'event_id\' => 1, \'event_price_type\' => 5, \'event_price\' => 5, \'event_price         


        

Answer 1

$prices = array(
        array('event_id' => 1, 'event_price_type' => 5, 'event_price' => 5, 'event_price_currency_id' => 1, 'event_price_info' => 'aaaa'),
        array('event_id' => 1, 'event_price_type' => 8, 'event_price' => 7, 'event_price_currency_id' => 1, 'event_price_info' => 'bbbb'), 
        array('event_id' => 1, 'event_price_type' => 1, 'event_price' => 8, 'event_price_currency_id' => 1, 'event_price_info' => 'cccc')
    );

i changed the typo, now I don't get an error but when i look at mysql there is only 1 row inserted:

event_id , price_type, price, price_currency, price_info;
0, 0, 0, 0, cccc;

where it has to be:

event_id , price_type, price, price_currency, price_info;
1, 5, 5, 1, aaaa;
1, 8, 7, 1, bbbb;
1, 1, 8, 1, cccc;

Answer 2

As Phantom said in his answer, You have a typo. There isevent_price_currency key in your array and :event_price_currency_id placeholder in prepare() statement. If fixing that doesn't work, try the following code and check the typo. Let me know if you face any problem.

try
{
   $DBH->beginTransaction();
   $STH = $DBH->prepare("INSERT INTO event_prices(event_id, event_price_type, event_price,  event_price_currency_id, event_price_info ) values (?, ?, ?, ?, ?)");

  foreach($prices as $price)
  {
    foreach($price as $row)
    {
        $data[] = $row;
    }

    $STH->execute($data);
    $data = NULL;
  }

  $DBH->commit();
}

catch(PDOException $e)
{
  echo 'Error ! ' . $e->getMessage();
  die();
}

Answer 3

You have a typo. There is event_price_currency key in your array and :event_price_currency_id placeholder in prepare() statement.

Answer 4

Your query is expecting this parameter:

:event_price_currency_id

Which you're not supplying. You are, however, supplying this parameter:

'event_price_currency' => 1

One of these things is not like the other.
