[英]Codeigniter : Fatal error: Call to a member function num_rows() on a non-object
[英]Codeigniter/Postgresql: Fatal error: Call to a member function num_rows() on a non-object
这件事困扰了我几天,而我却无法修复它。 我有这张注册表。 提交此表单时,此错误不断弹出,并且发生这种情况的原因是未将注册详细信息插入数据库。
我正在使用Postgresql作为数据库系统。 但是没有插入数据。 我对此感到非常沮丧。 我将在下面发布我的模型,控制器,如果需要任何信息,请告诉我。
控制器:
function register()
{
//set validation rules
$this->form_validation->set_rules('customer_name', 'Customer Name', 'trim|required|xss_clean');
$this->form_validation->set_rules('address1', 'Address 1', 'trim|required|xss_clean');
$this->form_validation->set_rules('address2', 'Address 2', 'trim|required|xss_clean');
$this->form_validation->set_rules('city', 'City', 'trim|required|xss_clean');
$this->form_validation->set_rules('state', 'State', 'trim|required|xss_clean');
$this->form_validation->set_rules('country', 'Country', 'trim|required|xss_clean');
$this->form_validation->set_rules('phone', 'Phone', 'trim|required|xss_clean|is_numeric');
$this->form_validation->set_rules('mobile', 'Mobile', 'trim|required|xss_clean|is_numeric');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|is_unique[gkb_users.email]');
$this->form_validation->set_rules('username', 'Username', 'trim|required|is_unique[gkb_users.username]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|md5');
$this->form_validation->set_rules('confpassword', 'Confirm Password', 'trim|required|matches[password]|md5');
//validate form input
if ($this->form_validation->run() == FALSE)
{
//fails
$this->loadHeader($this);
//load sidebar
$this->loadSidebar($this);
//load middle content
$this->load->view('register_view');
//load footer
$this->loadFooter($this);
}
else
{
//insert the user registration details into database
$data = array(
'cust_name' => $this->input->post('customer_name'),
'address1' => $this->input->post('address1'),
'address2' => $this->input->post('address2'),
'city' => $this->input->post('city'),
'state_code' => $this->input->post('state'),
'country_code' => $this->input->post('country'),
'phone' => $this->input->post('phone'),
'mobile' => $this->input->post('mobile'),
'email' => $this->input->post('email'),
'username' => $this->input->post('username'),
'password' => $this->input->post('password'),
);
// insert form data into database
if ($this->user_model->insertUser($data))
{
// send email
if ($this->user_model->sendEmail($this->input->post('email')))
{
// successfully sent mail
$this->session->set_flashdata('msg','<div class="alert alert-success text-center">You are Successfully Registered! Please confirm the mail sent to your Email-ID!!!</div>');
redirect('user/register');
}
else
{
// error
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('user/register');
}
}
else
{
// error
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('user/register');
}
}
}
模型:
function insertUser($data)
{
return $this->db->insert('users', $data);
}
如果能解决这个问题,我将不胜感激。 谢谢
编辑:
public function checkfrontendUser($username,$passwd)
{
$sql = "
SELECT * FROM users
WHERE (
`username` = '".$username."'
OR
`email` = '".$username."'
)
AND `password` = '".$passwd."'
";
$result = $this->db->query($sql);
if ($result->num_rows() > 0)
{
return $result->result_array();
}
return FALSE;
}
主要是由于数据库连接问题或查询失败而发生的。 不管如何,你是否是通过连接你的数据库database.php
或$this->load->database()
仔细检查您的Db凭据。
其次,您可以检查为
if($result !== FALSE){
if ($result->num_rows() > 0){
return $result->result_array();
}
}
