Nahrání obrázku do blob databáze MySQL v codeigniter

$this->input->post('photo') v modelu nebude fungovat pro načtení informací o obrázku. Protože obrázky jsou uloženy v $_FILES ne v $_POST. Musíte tedy použít knihovnu pro nahrávání v codeignitor jako níže.

public function update_profile() {
       $id = $this->session->userdata('id');
       $this->load->model('edit_profile_model');

       $config['upload_path'] = './uploads/';
       $config['allowed_types'] = 'gif|jpg|png';
       $config['max_size']  = '100';
       $config['max_width'] = '1024';
       $config['max_height'] = '768';

       $this->load->library('upload', $config);
       $this->upload->do_upload();//upload the file to the above mentioned path
       $this->edit_profile_model->update_db_user_info($id, $this->upload->data());// pass the uploaded information to the model
   } 

public function update_db_user_info($id, $imgdata) {
       $imgdata = file_get_contents($imgdata['full_path']);//get the content of the image using its path
       $data = array(
           'fullname' => $this->input->post('fullname'),
           'address' => $this->input->post('address'),
           'state' => $this->input->post('state'),
           'city' => $this->input->post('city'),
           'pincode' => $this->input->post('pincode'),
           'image' => $imgdata,
       );
       $this->db->where('id', $id);
       $this->db->update('userdetails', $data);
   } 

Chcete-li získat obrázek, napište do modelu funkci jako níže.

public function get_image($id){
       $this->db->where('id', $id);
       $result = $this->db->get('userdetails');
       header("Content-type: image/jpeg");
       echo $result['image'];
}

A také není dobré ukládat obrázek a načítat z databáze. Místo toho zkuste uložit obrázek do složky a uložit cestu do databáze, jak je uvedeno níže.

public function update_db_user_info($id, $imgdata) {
       $imgdata = $imgdata['full_path'];// get the path of the image
       $data = array(
           'fullname' => $this->input->post('fullname'),
           'address' => $this->input->post('address'),
           'state' => $this->input->post('state'),
           'city' => $this->input->post('city'),
           'pincode' => $this->input->post('pincode'),
           'image' => $imgdata,// change the type of image from blob to varchar or text
       );
       $this->db->where('id', $id);
       $this->db->update('userdetails', $data);
   }
