当我尝试在 codeigniter 中添加一列时,我正确添加了该列,但该值不是变量中的值...

当我定义:

<?php
$hwid = "123893944";
?>

数据库中的硬件 ID:“2147483647”

我不知道为什么...请帮助我!

模型:

<?php
class Prometheus_model extends CI_Model {

    var $tables = array(
        'bots' => 'bots',
        'users' => 'users'
    );

    function __construct() {
        parent::__construct();
    }

    public function tablename($table = NULL) {
        if(! isset($table)) return FALSE;
        return $this->tables[$table];
    }

    public function insert($table, $data) {
        $this->db->insert($this->tablename($table),$data);
        return $this->db->insert_id();
    }

    public function num_rows($table, $where = NULL) {
        if(isset($where)){
        $this->db->where($where);
        }
        $q = $this->db->get($table);
        return $q->num_rows();
    }

}

?>

控制器:

public function add_bot()
{

    $bot_data = json_decode($this->input->post('bot_data'));

    if($this->prometheus_model->num_rows('bots', array('bot_ip' => $_SERVER['REMOTE_ADDR'])) == 0){

        $to_insert = array(  
           'bot_id' => NULL,
           'bot_add_date' => time(),
           'bot_last_update' => time(), 
           'bot_os' => $bot_data->{'bot_os'},
           'bot_architecture' => $bot_data->{'bot_architecture'},
           'bot_ip' => $_SERVER['REMOTE_ADDR'],
           'bot_port' => $_SERVER['REMOTE_PORT'], 
           'bot_version' => $bot_data->{'bot_version'},
           'bot_name' => $bot_data->{'bot_name'},
           'bot_hw_id' => $bot_data->{'bot_hw_id'}
        );

        echo $to_insert['bot_hw_id']; //HERE IT IS CORRECT, BUT WRONG IN DATABASE! 
        $this->prometheus_model->insert('bots', $to_insert);  

    }
}

您面临的“问题”是您的 ID 比您的表可以存储的更大,请参见此处

INT -2147483648 - 2147483647

为了解决这个问题,请将您的bot_hw_id结构更改为unsigned给您更多的“范围”(仅在正值中),因为 ID 经常不是负数。

(或将其更改为BIGINT
