您好,我有以下功能和以下课程。问题是它只绑定了数组中的一个键,而不是所有键,我不知道为什么。
public function addData(Array $data)
{
$this->beginTransaction();
$this->query('INSERT INTO test (name, date) VALUES (:invoiceName, NOW())');
$this->bind(':invoiceName', uniqid());
$this->execute();
$this->query('INSERT INTO test_table (testId, username, type) VALUES (:invoiceId, :username, :type, )');
$this->bind(':invoiceId', $this->lastInsertId());
foreach($data as $key => $value)
{
$this->bind(':username', $value['name']);
$this->bind(':type', $value['type']);
}
$this->execute();
$this->endTransaction();
}
以及我将其用于数据库连接的类。
