使用 PDO 和 PHP 在 2 个表中插入多行

Question

I would like to insert 3 rows in table dictionary and another 3 rows in table banner, so in this example I left only 1 query for each table. the error I'm getting is

Object of class PDOStatement could not be converted to string

try {
$conn = new PDO('mysql:host=mysql;dbname=mydb;charset=utf8mb4', 'root', 'tiger');
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$conn->beginTransaction();

$conn->exec("INSERT INTO `dictionary` (`id`, `it`, `en`, `fr`, `es`, `pt`, `de`, `nl`) VALUES ('1', 'Sed tempus libero a tristique placerat.\r\n', 'Curabitur at justo sit amet mi aliquam vestibulum.\r\n', 'Duis sed elit suscipit, venenatis ipsum vitae, molestie elit.\r\n', 'Ut ac tortor semper, finibus est ac, porta erat.\r\n', 'Morbi sit amet quam facilisis, tristique mi a, sagittis quam.\r\n', 'Nulla nec sem quis velit tristique tempus vel id augue.\r\n', 'Mauris tincidunt leo eget tincidunt bibendum.\r\n')");
echo "New dictionary created successfully";

$stmt = $conn->prepare("INSERT INTO `banner` (`id`, `dictionaryId`, `name`, `destinationURL`, `domains`, `imageURL`, `position`, `startDate`, `finishDate`) VALUES ('5', '1', 'blink', 'github.com', 'Github', :imageURL, '5', '2019-04-18 03:00:00', '2019-05-04 00:00:00')");
$stmt->bindValue(':imageURL', $dropboxLink);
$stmt->execute();
$conn->commit();
echo "New banner created successfully";
} catch (PDOException $e) {
echo $stmt . "<br>" . $e->getMessage();
}

$conn = null;

Here is the modified code, try this

try {
  $conn = new PDO('mysql:host=mysql;dbname=mydb;charset=utf8mb4', 'root', 'tiger');
  $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  $conn->beginTransaction();

  $stmt1 = $conn->prepare("INSERT INTO `dictionary` (`id`, `it`, `en`, `fr`, `es`, `pt`, `de`, `nl`) VALUES ('1', 'Sed tempus libero a tristique placerat.\r\n', 'Curabitur at justo sit amet mi aliquam vestibulum.\r\n', 'Duis sed elit suscipit, venenatis ipsum vitae, molestie elit.\r\n', 'Ut ac tortor semper, finibus est ac, porta erat.\r\n', 'Morbi sit amet quam facilisis, tristique mi a, sagittis quam.\r\n', 'Nulla nec sem quis velit tristique tempus vel id augue.\r\n', 'Mauris tincidunt leo eget tincidunt bibendum.\r\n')");
  $stmt1->execute();
  echo "New dictionary created successfully";

  $stmt2 = $conn->prepare("INSERT INTO `banner` (`id`, `dictionaryId`, `name`, `destinationURL`, `domains`, `imageURL`, `position`, `startDate`, `finishDate`) VALUES ('5', '1', 'blink', 'github.com', 'Github', :imageURL, '5', '2019-04-18 03:00:00', '2019-05-04 00:00:00')");
  $stmt2->bindValue(':imageURL', $dropboxLink);
  $stmt2->execute();
  $conn->commit();
  echo "New banner created successfully";
} catch (PDOException $e) {
 echo $e->getMessage();
}
