CodeIgniter get_where


Question

I’m attempting to use get_where to grab a list of all database records where the owner is equal to the logged in user.

This is my function in my controller;

function files()
{
    $owner = $this->auth->get_user();

    $this->db->get_where('files', array('owner =' => '$owner'))->result();
}

And in my view I have the following;

<?php foreach($query->result() as $row): ?>

    <span><?=$row->name?></span>

<?php endforeach; ?>

When I try accessing the view, I get the Fatal error: Call to a member function result() on a non-object in /views/account/files.php on line 1.

Wondered if anyone had any ideas of what might be up with this?

Thanks

Accepted Answer

CodeIgniter is a framework based on MVC principles. As a result, you would usually separate application logic, data abstraction and "output" into their respective areas for CodeIgniter use. In this case: controllers, models and views.

Just for reference, you should usually have you "data" code as a model function, in this case the get_where functionality. I highly suggest you read through the provided User Guide to get to grips with CodeIgniter, it should hold your hand through most steps. See: Table of Contents (top right).

TL;DR

To solve your problem you need to make sure that you pass controller variables through to your view:

function files()
{
    $owner = $this->auth->get_user();

    $data['files'] = $this->db->get_where('files', array('owner =' => '$owner'))->result();

    $this->load->view('name_of_my_view', $data);
}

And then make sure to use the correct variable in your view:

<?php foreach($files as $row): ?>

    <span><?=$row['name']; ?></span>

<?php endforeach; ?>

<?php foreach($query->result() as $row): ?>

    <span><?=$row->name?></span>

<?php endforeach; ?>

Remove the result function like so.

<?php foreach($query as $row): ?>

    <span><?=$row->name?></span>

<?php endforeach; ?>

Btw. It's a much better idea to test the query for a result before you return it.

function files()
{
    $owner = $this->auth->get_user();

    $query = $this->db->get_where('files', array('owner =' => '$owner'))->result();

    if ($query->num_rows() > 0)
    {
        return $query->result();
    }
    return FALSE;
}
