我对 codeigniter 有疑问。当我尝试在这里登录时,结果是:
fatal error :在第 19 行调用 D:\xampp\htdocs\procurementSys\application\models\login_model.php 中 bool 值的成员函数 num_rows()
相关文件代码如下:
<?php
class Login_model extends CI_Model {
//this function checks whether the username and the password is in the database or not
public function check_login($username, $password){
$this->db->select('username, password, status');
$array = array('username' => $username, 'password' => sha1($password),'status' => 'active');
$this->db->where($array);
$query = $this->db->get('user');
if($query->num_rows() == 1) // if the affected number of rows is one
{
return true;
}
else
{
return false;
}
}
//this function returns the status of the user to be used in authentication
public function user_login_data($username, $password){
$this->db->select('status');
$array = array('username' => $username, 'password' => sha1($password));
$this->db->where($array);
$query = $this->db->get('user');
if($query->num_rows() == 1) // if the affected number of rows is one
{
$row = $query->row();
return $row->status;
}
// else
// {
// return false;
// }
}
public function user_role($username){ // this function gets the user's role from the database
$this->db->select('role');
$this->db->where('username', $username);
$query = $this->db->get('user');
$row = $query->row(0);
return $row->role;
}
public function department($username){ // this function gets the user's department from the database
$this->db->select('department');
$this->db->where('username', $username);
$query = $this->db->get('user');
$row = $query->row(0); // returns the first row with an array of objects that is stored in the row variable
return $row->department;
}
public function get_user_id($username){ // this function gets the user's department from the database
$this->db->select('userID');
$this->db->where('username', $username);
$query = $this->db->get('user');
$row = $query->row(0); // returns the first row with an array of objects that is stored in the row variable
return $row->userID ;
}
public function fullname($username){
$this->db->select('firstName, secondName');
$this->db->where('username', $username);
$query = $this->db->get('user');
$row = $query->row(0);
return $row;
// foreach($query->result() as $row) // returns the query as an array of objects
// {
// $data[] = $row; // equates the array of objects to an array variable
// }
//
// return $data;
// }
}
}

我一直在寻找解决方案并找到了这篇文章 (Call to a member function num_rows() on boolean)。它给了我一个想法,但没有真正的帮助。谢谢
最佳答案
我在启用 MySQL 严格模式时遇到了这个错误。当我禁用严格模式时,错误消失了。
检查此模式是否已启用
SHOW VARIABLES LIKE 'sql_mode';
禁用它
SET GLOBAL sql_mode = 'NO_ENGINE_SUBSTITUTION';
关于php - CODEIGNITER 调用成员函数 num rows on boolean,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/35630274/
