You just need to create a array, you using codeigniter right?

Example on controller:
```
$data['hello'] = "Hello, world";
$this->load->view('results_view', $data);
```
In de page "results_view" you just have to:
```
<?php echo $hello;?>
```
Obs: You can create n datas, just pay attention in the name and make it a array.

Obs²: To use the data use the key of the array with a echo.

you can do it this way

defined array in controller
```
$data['hello'] = "hello";
```
and pass variable to view
```
echo $hello; 
```

$data should be an array or an object: http://codeigniter.com/user_guide/general/views.html

$data = array(
    'title' => 'My Title',
    'heading' => 'My Heading',
    'message' => 'My Message'
);

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

results_view.php

<html>
<?php 
//Access them like so
echo $title.$heading.$message; ?>
</html>

In controller:

$data["result"] = $this->login_model->get_login(); // Get array value from DB..

$this->load->view('login-form',$data); // Pass the array to view

In view:

print_r($result);  // print the array in view file

Instead of
```
$data = "hello";
$this->load->view('results_view', $data);
```
Do
```
$data['hello'] = 'hello';
$this->load->view('results_view', $data);
```
In your controller file and controller will send data having hello as string to results_view and in your view file you can simply access by
```
echo $hello;
```

In controller:

public function product(){

$data = array("title" => "Books", "status"=>"Read","author":"arshad","company":"3esofttech",

"subject":"computer science");

Data From Model to controller

$this->load->model('bookModel');
$result = $this->bookModel->getMoreDetailsOfBook();

**Add *$result* from model to *$data* array**  
$data['tableRows'] = $result;

$data from Controller to View

$this->load->view('admin/head',$data);

And to access in view file views/user.php

<?php  echo $data;
 foreach($tableRows as $row){ echo
 $row['startData']; } ?>
