I want to upload the image to the mysql database for storing many information. I have attached the 3 (MVC) code for your reference and please help me.
ref: http://forum.codeigniter.com/thread-1205.html
I have to upload many images to database in blob type in codeigniter. I have written view, controller and model all details are uploading but image alone not storing.
Also please provide how to show the image in the codeigniter.
$this->input->post('photo') in model won't work to retrieve the image information. Because the images are stored in $_FILES not in $_POST. So you need to use the upload library in codeignitor like below.
In Controller:
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, $this->upload->data());// pass the uploaded information to the model
}
In Model:
public function update_db_user_info($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', $data);
}
To retrieve the image write a function in the model like below.
public function get_image($id){
$this->db->where('id', $id);
$result = $this->db->get('userdetails');
header("Content-type: image/jpeg");
echo $result['image'];
}
And also its not a good practice to store the image and retrieving from database. Instead of that try to store the image in a folder and store the path in the database like below.
In Model:
public function update_db_user_info($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);
}
