Question

Problem:
When try to store an image in MySql database field (BLOB) through codeigniter service, the image is not enabled in mysql. (I know is not a good practice but requirement). When is upload the image through mysl admin, image its ok.

I use postman with several text fields and one "file" field where i take the image to be stored in database.
Postman
Results of test:
All "text" fields are stored in database, the "file" field is uploaded to a directory as expected but the bynary data is not stored in database in field "foto"
Results in MySql

Answer 1

Try this:
public function CrearCliente() {
$user = $this->input->post('user');
$nombre = $this->input->post('nombre');
$apellido = $this->input->post('apellido');
$rut = $this->input->post('rut');
$correo = $this->input->post('correo');
$id_pais = $this->input->post('id_pais');
$fecha = $this->input->post('creacion');
$password = $this->input->post('password');
$presentacion = $this->input->post('presentacion');
$telefono = $this->input->post('telefono');
$long = 0;
$lat = 0;
$res = "null";
$this->load->library('form_validation');
$mimetypes = array("image/jpeg", "image/pjpeg", "image/gif", "image/png");
$foto = $_FILES['foto']['name'];
$tamanio = $_FILES['foto']["size"];
$archivo = $_FILES['foto']['tmp_name'];
$type = $_FILES['foto']['type'];
//$imagen = fopen($archivo, 'rb');
//$contenido2 = fread($imagen, $tamanio);
//fclose($imagen);
if (!in_array($type, $mimetypes)) {
// ci upload checks mimes for you
show_error("El archivo que subiste no es una imagen válida");
}
$config['upload_path'] = './imagenes/';
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '5000000';
$config['quality'] = '90%';
$config['overwrite'] = TRUE;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$config['file_name'] = $foto;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('foto')) {
//$error = array('error' => $this->upload->display_errors());
//$data['uploadError'] = $this->upload->display_errors();
show_error($this->upload->display_errors());
}
$contenido = file_get_contents($this->upload->data('full_path'));
$contenido3 = $this->db->escape_str($contenido);
$this->load->model('Usuario');
$res = $this->Usuario->InsertUsuario($contenido3, $user, $nombre, $apellido, $rut, $correo, $foto, $tamanio, $id_pais, $fecha, $password, $presentacion, $telefono, $long, $lat); // *se le asigna una variable al modelo para guardar el contenido que retorna la bd
header('content-type: application/json'); //* se colcoa una cabezera para decir que se va a retornar un Json
echo json_encode($res);
}
function InsertUsuario($contenido, $user, $nombre, $apellido, $rut, $correo, $foto, $tamanio, $id_pais, $fecha, $password, $presentacion, $telefono, $long, $lat) {
$hoy = getdate();
if ($foto) {
echo $contenido;
} else {
$imagen = null;
header('content-type: application/json');
echo json_encode("./upload/error.jpg"); // this doesn't seem valid, also you should probably exit
}
// no need for transaction when only running 1 query
$this->db->trans_strict(TRUE);
$this->db->trans_start();
$data = array(
'user' => $user,
'nombre' => $nombre,
'apellido' => $apellido,
'id_rut' => $rut,
'correo' => $correo,
'foto' => $contenido,
'id_pais' => $id_pais,
'password' => $password,
'presentacion' => $presentacion,
'telefono' => $telefono,
'creacion' => $fecha,
'long' => $long,
'lat' => $lat
);
$this->db->insert('wm_clientes', $data);
$this->db->trans_complete();
if ($this->db->trans_status() === FALSE) {
return $res = 'ERROR';
} else {
return $res = 'OK';
}
}
I would also suggest sending the array of data to the insert function instead of each as a parameter - it is messy and confusing and prone to errors. I also wouldn't suggest mixing string return types with json return types as it is an inconsistent interface. Also if you are using ajax you need to use FormData or a plugin to upload a file in case you weren't.

Answer 2

Any easy way around this would be to just store the image on your server (which you are doing already with your code) and then save the image name to your database as a varchar.
$config['upload_path'] = './imagenes/';
Above is the code that is uploading it to your server. It goes to that path on your server using the upload library provided by codeigniter.
You can now query your database for the image name, rather than the actual image, and use that in your view in an image tag. This will pull the image from the server.
If you have any questions about this method let me know.
