Question

当我在db中插入一个数组时，我在某些变量中得到错误“unidentified index”，即使它们都有相应的值。尝试使用print_r，它返回一个带有值的数组，但是当我尝试插入数组时，值变为null。我不明白为什么，我在代码中看不到错误。

这是我的控制器

public function test()
{

    if($this->session->userdata('logged_in'))
    {
        $session_data = $this->session->userdata('logged_in');
        $user_id = $session_data['user_id'];

        $table_id = $this->input->post('table');
        $start = $this->input->post('start');
        $end = $this->input->post('end');

        $query = $this->process_resto_list->test($table_id);


        if ($query->num_rows() > 0)
        {
           $row = $query->row(); 

           $resto_id    = $row->resto_id;
           $table_number= $row->table_number;
           $table_size  = $row->table_size;
        }
        //$resto_id = $session_data['user_id'];

        $values = array(
                'resto_id'              => $resto_id,
                'diner_id'              => $user_id,
                'date'                  => $this->input->post('date'),
                'start_time'            => $start,
                'end_time'              => $end,
                'table_number'          => $table_number,
                'number_of_people'      => $table_size,
        );

        if($this->process_resto_list->insert_reservation($values))
            redirect('reservation_test/reservation', 'location');
        //print_r($values);
    }

这是我的模特

public function insert_reservation($values)
{
    date_default_timezone_set("Asia/Manila");
        $data = array(

                'resto_id'              => $values['resto_id'],
                'diner_id'              => $values['user_id'],
                'date'                  => date('Y-m-d'),
                'start_time'            => $values['start'],
                'end_time'              => $values['end'],
                'table_number'          => $values['table_number'],
                'number_of_people'      => $values['table_size'],

            );

            return $this->db->insert('resto_reservations', $data);
}

使用print_r时，这是数组的结果

数组（[resto_id] =＆gt; 9 [diner_id] =＆gt; 14 [日期] =＆gt; [start_time] =＆gt; 11:00 [end_time] =＆gt; 13:00 [table_number] =＆gt; 6 [number_of_people] =＆gt; 4）

请帮我指出错误。谢谢

在你的模特中。更改值如下

$data = array(

            'resto_id'              => $values['resto_id'],
            'diner_id'              => $values['diner_id'],
            'date'                  => date('Y-m-d'),
            'start_time'            => $values['start_time'],
            'end_time'              => $values['end_time'],
            'table_number'          => $values['table_number'],
            'number_of_people'      => $values['number_of_people'],

        );

我刚刚用这个替换了我的模型。谢谢大家！

$data = array(

            'resto_id'              => $values['resto_id'],
            'diner_id'              => $values['diner_id'],
            'date'                  => date('Y-m-d'),
            'start_time'            => $values['start_time'],
            'end_time'              => $values['end_time'],
            'table_number'          => $values['table_number'],
            'number_of_people'      => $values['number_of_people'],

        );
