我正在使用insert_batch这么久，我无法弄清楚它是如何工作的，所以我需要一些指导来解决这个错误。

You must use the "set" method to update an entry.

我正在使用CI 2并且出现错误，因为我以这种方式调用insert_batch：

返回$ this-＆gt; db-＆gt; insert_batch（'tbl_quiz_answer'，$ data）;

$ data转储如下所示：

array(9) {
  [0]=>
  array(4) {
    ["id_quiz_master"]=>
    string(3) "500"
    ["id_quiz_question"]=>
    int(3248)
    ["id_student"]=>
    string(3) "305"
    ["answer"]=>
    string(3) "asd"
  }

  array(4) {
    ["id_quiz_master"]=>

}

请帮助我，我不知道我做错了什么。

以下是如何为insert_batch构建数组的示例。它可能不完全像您需要它但它可以正常工作并执行插入。

public function post_message( $post, $user_id )
{
    $message_data = array();

    foreach ($post[ 'to_id' ] as $key) {
        $message = array(
            'from_id'        => $user_id,
            'to_id'          => $key,
            'message'        => $post[ 'message' ],
            'sent_date_time' => date( 'Y-m-d H:i:s' )
            );
        $message_data[] = $message;
    }

    $this->db_central->insert_batch( 'messages', $message_data );

}

使用codeigniter insert_batch时出错
