Codeigniter数据库错误：列不存在

Question

I've followed a few tutorials online on learning the CodeIgniter framework. I've tried to make a login and register function and everything should be working correctly however instead it shoots me back this error after I submit the register form.

A Database Error Occurred

Error Number: 1054

Unknown column 'user_name' in 'field list'

INSERT INTO 'users' ('user_name', 'user_password_hash', 'user_email') VALUES ('Test2', '$2a$08$cAkWVsvkaXvaumfcxW0gAOx2mBZMhIXxDpTQpHkOVme8l.1r9mok2', '1111')

/www/application/models/user_model.php

Line Number: 41

On line 41 of User_model.php is $this->db->insert('users');

public function add_user()
{
    $passunhash = $this->input->post('password');
    $passhash = $this->bcrypt->hash_password($passunhash);
    $uname = $this->input->post('user_name');
    $opin = $this->input->post('pin');

    $this->db->set('user_name', $uname);
    $this->db->set('user_password_hash', $passhash);
    $this->db->set('user_email', $opin);
    $this->db->insert('users');
}

The database.php config file has been edited to include the correct database name.

I cannot figure out why it would be giving me this database error. The column does exist. Could it be an issue with CodeIgniter?

Answer 1

As zack tanner mentioned in the comments running SHOW COLUMNS FROM yourDB.users; from a mysql command line returns with all of the columns that the mysql client can read.

My PHPMYADMIN was getting old data and so running from command line displayed the realtime info. I was able to finish the rest of the commands through the command line in order to re structure the DB

This may not solve your problem but when inserting user you can use a data array(); and not have multiple db->set()

public function add_user() {

$passunhash = $this->input->post('password');
$passhash = $this->bcrypt->hash_password($passunhash);

$data = array(
    'user_name' => $this->input->post('user_name'),
    'user_password_hash' => $passhash,
    'user_email' => $this->input->post('pin')
);

$this->db->set($data);
$this->db->insert($this->db->dbprefix . 'users');
}
