CodeIgniter: Unknown column 'xxx' in 'field list' - codeigniter

Question

Here's my exported BD table:
CREATE TABLE `hta_users` (
`id` int(11) NOT NULL auto_increment,
`nombre` varchar(100) collate utf8_spanish_ci NOT NULL,
`apellidos` varchar(255) collate utf8_spanish_ci NOT NULL,
`nif` varchar(10) collate utf8_spanish_ci NOT NULL,
`direccion` varchar(255) collate utf8_spanish_ci NOT NULL,
`cp` varchar(5) collate utf8_spanish_ci NOT NULL,
`poblacion` varchar(255) collate utf8_spanish_ci NOT NULL,
`provincia` int(2) NOT NULL,
`telefono` varchar(9) collate utf8_spanish_ci NOT NULL,
`edad` int(3) NOT NULL,
`retribucion` int(1) NOT NULL,
`entidad` varchar(4) collate utf8_spanish_ci NOT NULL,
`oficina` varchar(4) collate utf8_spanish_ci NOT NULL,
`dc` varchar(2) collate utf8_spanish_ci NOT NULL,
`cc` varchar(10) collate utf8_spanish_ci NOT NULL,
`centro` varchar(255) collate utf8_spanish_ci NOT NULL,
`email` varchar(255) collate utf8_spanish_ci NOT NULL,
`especialidad` int(2) NOT NULL,
`parent` int(11) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `nif` (`nif`,`email`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci AUTO_INCREMENT=1 ;
Here's my model function:
function add_user( $nombre, $apellidos, $nif, $direccion, $cp, $poblacion, $provincia, $telefono, $edad, $retribucion, $cc_entidad, $cc_oficina, $cc_dc, $cc_cc, $centro, $email, $especialidad, $parent )
{
$tbl = $this->db->dbprefix('users');
if( $retribucion == 1 )
{
$sql = array(
'nombre' => $nombre,
'apellidos' => $apellidos,
'nif' => $nif,
'direccion' => $this->db->escape($direccion),
'cp' => $cp,
'poblacion' => $poblacion,
'provincia' => $provincia,
'telefono' => $telefono,
'edad' => $edad,
'retribucion' => $retribucion,
'entidad' => $cc_entidad,
'oficina' => $cc_oficina,
'dc' => $cc_dc,
'cc' => $cc_cc,
'centro' => $centro,
'email' => $email,
'especialidad' => $especialidad,
'parent' => $parent
);
}
else
{
$sql = array(
'nombre' => $nombre,
'apellidos' => $apellidos,
'nif' => $nif,
'direccion' => $this->db->escape($direccion),
'cp' => $cp,
'poblacion' => $poblacion,
'provincia' => $provincia,
'telefono' => $telefono,
'edad' => $edad,
'retribucion' => $retribucion,
'centro' => $centro,
'email' => $email,
'especialidad' => $especialidad,
'parent' => $parent
);
}
$this->db->insert($tbl, $sql);
if( $this->db->affected_rows() == 0 ) return false;
else return true;
}
Here's my controller piece of code:
if( $this->users->add_user($nombre, $apellidos, $nif, $direccion, $cp, $poblacion, $provincia, $telefono, $edad, $retribucion, $cc_entidad, $cc_oficina, $cc_dc, $cc_cc, $centro, $email, $especialidad, $parent) )
{
$data['form_error'] = 'Se ha añadido al usuario.';
$data['module'] = 'registro';
$this->load->view('template', $data);
}
else
{
$data['form_error'] = 'Se ha producido un error al agregar al usuario a la BD.';
$data['module'] = 'registro';
$this->load->view('template', $data);
}
And that's the error i'm getting:
A Database Error Occurred
Error Number: 1054
Unknown column 'entidad' in 'field list'
INSERT INTO `hta_users` (`nombre`, `apellidos`, `nif`, `direccion`, `cp`, `poblacion`, `provincia`, `telefono`, `edad`, `retribucion`, `entidad`, `oficina`, `dc`, `cc`, `centro`, `email`, `especialidad`, `parent`) VALUES ('nombre', 'apellidos', '12345678Q', '\'elm st 666\'', '08008', 'Barcelona', '1', '666555666', '2', 1, '9999', '9999', '99', '9999999999', 'home', 'email#domain.com', '1', '0')
Can someone help? I don't know what's happening nor why... :/

Answer 1

Here is an article I wrote that will help you with debugging CodeIgniter ActiveRecord. Basically use $this->db->last_query() to see what ActiveRecord built your query to be and run it in phpMyAdmin to see if the query itself is valid.
There are a few other tips too, but from what I can see here everything looks fine.
Sneaky tip: you can use:
return !$this->db->affected_rows() == 0;
instead of:
if( $this->db->affected_rows() == 0 ) return false;
else return true;

Answer 2

Well, after some hours of harddebuggin' got it working... :P
Same database table structure.
My new model function:
function add_user( $user_data )
{
$tbl = $this->db->dbprefix('users');
$this->db->insert($tbl, $user_data);
return !$this->db->affected_rows() == 0;
}
My new controller piece of code:
$user_data = array(
'nombre' => $this->input->post('nombre'),
'apellidos' => $this->input->post('apellidos'),
'nif' => $this->input->post('nif'),
'direccion' => $this->db->escape($this->input->post('direccion')),
'cp' => $this->input->post('cp'),
'poblacion' => $this->input->post('poblacion'),
'provincia' => $this->input->post('provincia'),
'telefono' => $this->input->post('telefono'),
'edad' => $this->input->post('edad'),
'retribucion' => $this->input->post('retribucion'),
'entidad' => $this->input->post('cc_entidad'),
'oficina' => $this->input->post('cc_oficina'),
'dc' => $this->input->post('cc_dc'),
'cc' => $this->input->post('cc_cc'),
'centro' => $this->input->post('centro'),
'email' => $this->input->post('email'),
'especialidad' => $this->input->post('especialidad'),
'parent' => $this->session->userdata('parent')
);
// db adding
if( $this->users->add_user($user_data) )
{
// logged in!!
}
else
{
// grrr error!!
}
It looks much pretty now! :)
Hope this helps some lost souls to DO NOT construct the AR data array into the model, but the controller.
