This is my codeigniter controller function. Using this function, I can add data to the database. But, I am unable to upload image. Even upload_files is enabled in php.ini. I tried resolving this problem all day long, but all in vain.
I have not used enctype in my html form because when I use enctype, I get the below error:
undefined Index filename

Your path is wrong.
'upload_path' => '' .base_url(). '/assets/img/logo/',
Note: Make sure your upload path "assets folder" is in the main directory out side of
application folder. You also may need to set folder permissions.
Try
'upload_path' => FCPATH . 'assets/img/logo/'
or just
'upload_path' => './assets/img/logo/'
To access file info after upload success preferences
$image_info = $this->upload->data();
echo $image_info['file_name'];
Or Through Model
$this->insert_model->form_insert($data, $image_info = array());
