Trying to get property of non-object

You can pass a database result object directly to table->generate(). It saves you all the trouble of looping through result_array().

The model becomes

PHP Code:

/**
 * @return an instanceof CI_DB_result
 */
public function memberslist()
{
 return $this->db
 ->order_by('username', 'ASC')
 ->get('users');
} 


The controller will work as you have it.
