How to Pass Data from a CodeIgniter Controller to a View?

Passing Data from Controller to View in Codeigniter

Question:

In Codeigniter, I'm trying to pass a variable named $data from the poll controller to the results_view. However, I'm encountering an undefined variable error. Here's the code I'm using:

<code class="php">// ...

public function results()
{
    // ...
    $data = "hello";
    $this->load->view('results_view', $data);
}</code>

Answer:

In Codeigniter, when passing data from a controller to a view, $data should be an array or an object.

To resolve this issue, convert $data into an array:

<code class="php">$data = array(
    'hello' => 'hello',
);</code>

or an object:

<code class="php">$data = (object) array(
    'hello' => 'hello',
);</code>

Then, in results_view.php, access the data as follows:

<code class="php">echo $data->hello;</code>
