Question

此代码的最后一行似乎返回一个对象但不执行数据库查询。如何更改以实际执行数据库更新？

$sql = "UPDATE vi_admin_email SET processed_send_list = '?', status = '?' WHERE id = '?'";
$bind = array($addresses,$status,$id);
$res = $this->getAdapter()->query($sql,$bind);

这是$ res中对象的var转储：

  protected '_fetchMode' => int 2
  protected '_stmt' => 
    object(PDOStatement)[100]

protected'_queryId'=＆gt;空

Answer 1

要更新Zend Framework中的条目，请执行以下操作：

$data = array(
    'processed_send_list' => $addresses,
    'status' => $status
);

$dbAdapter = $this->getAdapter();

$where = $dbApdapter->quoteInto('id = ?', $id);

$this->update($data, $where);

使用Zend_Db_Table，要更新的数据在associative array中指定为第一个参数。执行查询时，将提供所提供的数据。您还必须将where语句作为字符串包括在内，例如id = 1作为第二个参数。在上面的示例中，quoteInto是可选的，因为您可以手动编写where，但如果您手动执行此操作，则不会转义该值。

Answer 2

我以为我读了“查询”，但你问的是“更新”。

所以声明如下：

$水库＆GT;执行（）

忘记我之前写的内容。

Answer 3

试试这一行代码，

$res = $this->getAdapter()->query("UPDATE vi_admin_email SET processed_send_list = '$addresses', status = '$status' WHERE id = '$id'");
