Codeigniter-即使页面加载或刷新，空白行也会插入到mysql中

Question

我正在尝试将一些表单数据插入到codeigniter中的mysql表中。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，即使页面加载或刷新，空行也会插入到mysql中。

这是我的代码：

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'),
            'cust_address' => $this->input->post('addr'),
            'contact_person' => $this->input->post('contact_prsn'),
            'location' => $this->input->post('loc'),
            'email' => $this->input->post('email'),
            'prs' => $this->input->post('prs'),
            'rating' => $this->input->post('rating'),
            'hrs' => $this->input->post('hrs'),
            'engine_num' => $this->input->post('engine'),
            'model' => $this->input->post('model'),
            'amc_from' => $this->input->post('amcfrom'),
            'amc_to' => $this->input->post('amcto'),
            'expiry_date' => $this->input->post('expd'),
            'no_visit_agreed' => $this->input->post('visagree'),
            'no_visit_made' => $this->input->post('vismade'),
            'date_commence' => $this->input->post('doc'), 
            'last_oil_ser_date' => $this->input->post('losd'),
            'last_visit_date' => $this->input->post('lvd'),
            'visit_due' => $this->input->post('visitdue'),
            'visit_status' => $this->input->post('visitstatus'),
            'svc_status' => $this->input->post('svcstatus'),
            'amc_status' => $this->input->post('amcstat'),
            'actual_amt' => $this->input->post('actualamt'),
            'amt_recieved' => $this->input->post('amtrecieved'),
            'amt_due' => $this->input->post('amountdue'),
            'payment_method' => $this->input->post('paymentmethod'),
            'payment_due_date' => $this->input->post('paymentdue'),
            'assigned_to' => 'not assigned'
        );
    $this->amc_model->addamc($data);

    if ( $this->form_validation->run() == true &&$this->amc_model->addamc($data) )
    { 
        $this->session->set_flashdata('success_message', $this->lang->line('amc_added'));
        redirect("module=amc", 'refresh');
    }
}

模型：

class Amc_model extends CI_Model
{
public function __construct()
{
    parent::__construct();

}
public function addamc($data = array())
{   
   $amcData = array(
                     'cust_id'  => $data['cust_id'],
                 'cust_name' => $data['cust_name'],
              'cust_address' => $data['cust_address'],  
              'contact_person' => $data['contact_person'],  
              'location' => $data['location'],  
              'email' => $data['email'],    
              'prs' => $data['prs'],    
              'rating' => $data['rating'],
              'hrs' => $data['hrs'],
              'engine_num' => $data['engine_num'],
              'model' => $data['model'],
              'amc_from' => $data['amc_from'],
              'amc_to' => $data['amc_to'],
              'expiry_date' => $data['expiry_date'],
              'no_visit_agreed' => $data['no_visit_agreed'],
              'no_visit_made' => $data['no_visit_made'],
              'date_commence' => $data['date_commence'],
              'last_oil_ser_date' => $data['last_oil_ser_date'],
              'last_visit_date' => $data['last_visit_date'],
              'visit_due' => $data['visit_due'],
              'visit_status' => $data['visit_status'],
              'svc_status' => $data['svc_status'],
              'amc_status' => $data['amc_status'],
              'actual_amt' => $data['actual_amt'],
              'amt_recieved' => $data['amt_recieved'],
              'amt_due' => $data['amt_due'],
              'payment_method' => $data['payment_method'],
              'payment_due_date' => $data['payment_due_date'],
              'assigned_to' => $data['assigned_to'] 
    );

    if($this->db->insert('amc_details', $amcData)) {
        return true;
    } else {
        return false;
    }
}   
}

我是codeigniter的菜鸟，我无法找到代码的错误。任何人都可以帮我这个..

在控制器中，只有在验证为真时才应调用插入代码。

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

应该在控制器函数addamc（）中进行更改。最终的代码将是

function addamc()
{
            $data = array('cust_id' => $this->input->post('customer_id'),
            'cust_name' => $this->input->post('cname'),
            'cust_address' => $this->input->post('addr'),
            'contact_person' => $this->input->post('contact_prsn'),
            'location' => $this->input->post('loc'),
            'email' => $this->input->post('email'),
            'prs' => $this->input->post('prs'),
            'rating' => $this->input->post('rating'),
            'hrs' => $this->input->post('hrs'),
            'engine_num' => $this->input->post('engine'),
            'model' => $this->input->post('model'),
            'amc_from' => $this->input->post('amcfrom'),
            'amc_to' => $this->input->post('amcto'),
            'expiry_date' => $this->input->post('expd'),
            'no_visit_agreed' => $this->input->post('visagree'),
            'no_visit_made' => $this->input->post('vismade'),
            'date_commence' => $this->input->post('doc'), 
            'last_oil_ser_date' => $this->input->post('losd'),
            'last_visit_date' => $this->input->post('lvd'),
            'visit_due' => $this->input->post('visitdue'),
            'visit_status' => $this->input->post('visitstatus'),
            'svc_status' => $this->input->post('svcstatus'),
            'amc_status' => $this->input->post('amcstat'),
            'actual_amt' => $this->input->post('actualamt'),
            'amt_recieved' => $this->input->post('amtrecieved'),
            'amt_due' => $this->input->post('amountdue'),
            'payment_method' => $this->input->post('paymentmethod'),
            'payment_due_date' => $this->input->post('paymentdue'),
            'assigned_to' => 'not assigned'
        );


        if ( $this->form_validation->run() == true)
        { 

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

           if($result == true) {
              $this->session->set_flashdata('success_message', $this->lang->line('amc_added'));
              redirect("module=amc", 'refresh');
           } else {
              //insertion failed
           }
        }
}

只有在验证为真的情况下才能执行insert语句。
