Codeigniter Rest Api Delete using parameter ID - rest

Question

I'm Learning CRUD operation with Codeigniter and Rest Api for my app Flutter.But I'm get some problem with Delete operation. I'm want delete data using parameter ID , but the message show me ID Null.
It's my Get Operation using parameter
http://192.168.43.159/wpu-rest-server/apii/mahasiswa/get?id=5
Possible i'm make delete operation like this ?
http://192.168.43.159/wpu-rest-server/apii/mahasiswa/delete?id=5
I already try
http://192.168.43.159/wpu-rest-server/apii/mahasiswa/delete/5
http://192.168.43.159/wpu-rest-server/apii/mahasiswa/delete/id/5
But Nothing change , still ID null.
It's my Controller And Model Rest Api :
Controller
public function delete_delete()
{
$id = $this->delete('id');
$msgDelete = ['id' => $id, 'message' => 'Deleted the resource'];
$msgEmpty = ['status' => false, 'message' => 'ID Not Found'];
$msgBadRequest = ['status' => false, 'message' => 'Provide an ID'];
if ($id === null) {
$this->set_response($msgBadRequest, 400);
} else {
if ($this->mahasiswa->deleteMahasiswa($id) > 0) {
$this->set_response($msgDelete, 204);
} else {
$this->set_response($msgEmpty, 404);
}
}
}
Model
public function deleteMahasiswa($id)
{
$this->db->delete('mahasiswa', ['id' => $id]);
return $this->db->affected_rows();
}

I am seeing some ambigius things in your code for example the api url is :
http://192.168.43.159/wpu-rest-server/apii/mahasiswa/delete/5
and your controller method name is delete_delete .
If you are using the get method you should respect the following :
base_url/controller_name/method_name?id=3
and then you can get the value with :
$this->input->get('id')
otherwise if you are passing the id as a method argument like the following :
http://your_domain/controller_name/delete/5
you can get the value like this :
class controller_name extends CI_Controller {
.
.
.
public function delete($id=null){
}
}

If Possible do like this
192.168.43.159/wpu-rest-server/apii/mahasiswa/delete_delete?id=5
Controller
public function delete_delete() {
$id = $this->input->get('id');
$this->mahasiswa->deleteMahasiswa($id);
redirect('http://192.168.43.159/wpu-rest-server/apii/mahasiswa');
}
Model
function deleteMahasiswa() {
$this->db->where('id', $id);
$this->db->delete('mahasiswa');
}
