Image is not being uploaded into Database

Hello

PHP Code:

           $slug = str_replace(' ', '-', $this->input->post('title'));
            $slug = strtolower($slug);
            
            $subject_name = str_replace(' ', '-', $this->input->post('subject_name'));
            $subject_name = strtolower($subject_name);

            // Upload Image
            $config['upload_path'] = 'assets/img/posts/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['encrypt_name'] = TRUE;
            $config['max_size'] = '2048';
            $config['max_width'] = '2000';
            $config['max_height'] = '2000';
            $this->load->library('upload', $config);
            $this->upload->initialize($config);
                    
            
            $file_name = 'post_image';
            
            if(!$this->upload->do_upload($file_name)){
                varDebug($this->upload->display_errors());
                $file_name = base_url().'assets/img/noimage.jpg';
            } else {
                $data = array('upload_data' => $this->upload->data($file_name));
            }

            // Page Data
            $data = array(
                'subject_id'    => $this->input->post('subject_id'),
                'subject_name'    => $subject_name,
                'user_id'        => $this->input->post('user_id'),
                'username'        => $this->input->post('username'),
                'slug'            => $slug,
                'title'            => $this->input->post('title'),
                'post_image'    => $file_name,
                'body'            => $this->input->post('body'),
                'is_published'    => $this->input->post('is_published'),
                'is_featured'    => $this->input->post('is_featured'),
                'in_menu'        => $this->input->post('in_menu'),
                'is_commented'    => $this->input->post('is_commented'),
                'order'            => $this->input->post('order'),
            );
            
            // Insert Page
            $this->Post_model->add($data); 


I already tried by commenting the $data = array('upload_data' => $this->upload->data($file_name)); just after the else to then use this on my array in the post_image value, and If I do that it throws me an error of post_image cannot be NULL...

PHP Code:

'post_image'    => $this->upload->data($file_name) 


Any help?

The Code works in general, I mean, it sends the file to the folder, the problem is that is does not upload the picture into the database under the post_image value. What it actually sends is the data inside the file_name variable that is just after initializing the upload config.

PHP Code:

$file_name = 'post_image';

PHP Code:

'post_image'    => $this->upload->data($file_name);

// Should be
'post_image'    => $this->upload->data('file_name'); 


What did you Try? What did you Get? What did you Expect?
