Q:

base query method in CodeIgniter

Im trying to create a base query that I can then use later to add grouping or filters
simplified example:
function baseQuery()
{
    $query = $this->db->select('*')
    return $query;
}

function queryWhere($value)
{
    $query = $this->baseQuery();
    $query->where($value)
    $result = $query->get();

    return $result
}

What is the correct way to do this in CodeIgniter?

A:

Your code needs some dynamic values like table and field names for extending single purpose of query
Take a look on example 
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Testing extends CI_Controller {

    public function baseQuery($fields,$tableName)
    {
        $query = $this->db;
        $query->select($fields);
        $query->from($tableName);
        return $query;
    }

    public function queryWhere($whereCondition)
    {
        $query = $this->baseQuery('*','tablename');
        $query->where($whereCondition);
        $result = $query->get();
        return $result;
    }
    public function index() {

        $query = $this->queryWhere("id > 0");
        $data = $query->result_array();
        print_r($data);
    }  

}
