Hope this will help you :
Note : make sure you have load database and upload library either in autoload or in controller
First your form should be like this :
<?php echo form_open_multipart('AddPlant/InsertPlant')?>
............
<?php echo form_close();?>
Your controller should be like this :
public function InsertPlant()
{
/*here make sure your path is correct*/
$config['upload_path'] = FCPATH .'assets/uploads/';
$config['allowed_types'] = '*';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('plantimg'))
{
$error = array('error' => $this->upload->display_errors());
print_r($error);die;
}
else
{
//$data = array('upload_data' => $this->upload->data());
$file_name = $this->upload->data('file_name');
/*here assuming that your column name for image is image_name, change it not*/
$data =array(
'name'=> $this->input->post('name',TRUE),
'description'=> $this->input->post('description',TRUE),
'age'=> $this->input->post('age',TRUE),
'image_name'=> $file_name,
);
return $this->db->insert('plants',$data);
}
}
