Unknown column 'postTable' in 'field list' - php

Question

I'm using codeigniter and this is located in my model. I have this error Unknown column 'postTable' in 'field list' . I hope you can help me and thank you in advance.
public function getManufacturer()
{
$condition = array('manufacturer_id' => $this->manufacturer_id);
$query = $this->db->get_where('manufacturer', $condition);
return $query->row_array();
}
public function updateManufacturer()
{
$this->db->where('manufacturer_id',$this->manufacturer_id);
$query = $this->db->update('manufacturer', $this);
return $query;
}
And this is my controller
public function updateForm()
{
$data = array();
$this->load->model('asset_model');
$p = new asset_model();
$p->manufacturer_id = $this->input->post('manufacturer_id');
$data = $p->getManufacturer();
$this->load->view('updateForm',$data);
}
public function update()
{
$this->load->model('asset_model');
$p = new asset_model();
$p->manufacturer_id = $this->input->post('manufacturer_id');
$p->manufacturer_name = $this->input->post('manufacturer_name');
$status = $p->updateManufacturer();
if ($status == true) {
redirect('asset_management/manufacturers');
}
}

Answer 1

Try this
In your controller
public function updateForm()
{
$data = array();
$this->load->model('asset_model');
$manufacturer_id = $this->input->post('manufacturer_id');
$data = $this->asset_model->getManufacturer($manufacturer_id);
$this->load->view('updateForm',$data);
}
public function update()
{
$this->load->model('asset_model');
$manufacturer_id = $this->input->post('manufacturer_id');
$manufacturer_name = $this->input->post('manufacturer_name');
$status = $this->asset_model->getManufacturer($manufacturer_id);
if ($status == true) {
redirect('asset_management/manufacturers');
}
}
In Model
public function getManufacturer($manufacturer_id)
{
$condition = array('manufacturer_id' =>$manufacturer_id);
$query = $this->db->get_where('manufacturer', $condition);
return $query->row_array();
}
public function updateManufacturer($manufacturer_id)
{
$condition = array('manufacturer_id' =>$manufacturer_id);
$query = $this->db->update('manufacturer', $condition);
return $query;
}
