hi,

I am beginner, below is my code 

<?php namespace App\Controllers;
use App\Models\product

class Product extends BaseController
{
public function post()
{
$data = $userModel->findAll();
return view('home',$data);
}

//--------------------------------------------------------------------
}


can you please tell me what is wrong?

error message is "Undefined variable: data"

how to retrieve data and display in view?

You did not call the model function this code is totally wrong. Actually I did not know your model but you trying to use userModel you need to call out the user model

$userModel = new UserModel();

Then you need to call out the model via namespace
use App\Models\UserModel;

yes i was about to reply saying your not giving us enough information . Also really we need to see how you are doing  allowed fields if using CI model and whether your database is set up. I recommend sqlite for easy start can help with that if required

thank you 
will do
can you help me with retrieving data and display?

[jreklund]

Based on the code provided the only way it can be undefined are this:

Code:

$data = array();
$data['posts'] = $model->findAll();
return view('home',$data);

Other than that you aren't calling it from somewhere.
