Php Codeigniter-即使在页面加载或刷新时，也会将空白行插入mysql

我试图在codeigniter中将一些表单数据插入mysql表。我的问题是，在插入实际数据之前，会在表中插入一个空行。然后我发现，即使在页面加载或刷新时，一个空行也会被插入到mysql中

这是我的密码：

控制器：

class Amc extends MX_Controller {
function __construct()
{
    parent::__construct();

    // check if user logged in 
    if (!$this->ion_auth->logged_in())
    {
        redirect('module=auth&view=login');
    }
    $this->load->library('form_validation');
    $this->load->model('amc_model');

}
function addamc()
{
            $data = array('cust_id' => $this->input->post('customer_id'),
            'cust_name' => $this->input->post('cname'),

        );
    $this->amc_model->addamc($data);

在控制器中，仅当验证为真时，才应调用插入代码

$this->amc_model->addamc($data);

应在控制器函数addamc（）中进行更改。最后的代码是

我已经按照您所说的做了，现在页面加载或刷新插入没有发生。但即使我提交表单数据，也不会插入数据。尝试将“form_open”格式更改为form_open（'amc/addamc'，$attrib）；尝试更改代码回送表单_open（“module=amc&；view=addamc”，$attrib）；鉴于echo form_open（'amc/addamc'，$attrib）；另外，请检查验证是否工作正常。我已经按照您所说的做了，现在页面加载或刷新插入没有发生。但即使我提交表单数据，也不会插入数据。尝试将“form_open”格式更改为form_open（'amc/addamc'，$attrib）；尝试更改代码回送表单_open（“module=amc&；view=addamc”，$attrib）；鉴于echo form_open（'amc/addamc'，$attrib）；另外，请检查验证是否有效。
