>> My view open - register_open

<?php

$this->load->view('mains/footer');
?>

>>My view - register_view

<?php echo form_open('verifyregistration/index'); ?>
    <form>
        <label for="username">Login:</label>
        <input type="text" size="25" id="Login" name="Login" set_value='Login' /> 
        .
        .
        .

        <legend>
            <input type="checkbox" id="regulamin" name="Regulamin" onclick="this.form.elements['Wyslij'].disabled = !this.checked" /> 
            Akceptuję regulamin serwisu. </legend>

            <label>&nbsp;</label>
            <input type="submit" name="Wyslij" value="Wyslij" disabled="disabled"/>
            <label>&nbsp;</label>

        <legend>
            <<?php echo $heading;?>
        </legend>
    </form>

And I have errors:

Severity: Notice Message: Undefined variable: data Filename: register/register_open.php Line Number: 9 this line-> $this->load->view('register/register_view',$data);

Severity: Notice Message: Undefined variable: heading Filename: register/register_view.php Line Number: 48 this line-> <<?php echo $heading;?>

How I can pass the data to another view?

First thing to change is class names have the first letter capitalized in the declaration. It should be: class Verifyregistration extends CI_Controller { — Rick Calder

In your controller, change

$this->load->view('register/register_open',$data)

to

$this->load->view('register/register_open',array('data' => $data));

When you do $this->load->view('view', $variable) it takes $variable and uses the php function extract() to turn the array keys into variables. So, if you want to use the variable $data in a nested view, you have to send another array like I did above.

When I change this line in my controller to: {$this->load->view('register/register_open',array('data' => $data));} Errors are still this same.

It should work, but to test, please do this: In your register_open view, put die(var_dump($data)); as the first line, and see what it outputs.

when i add this line, I have this error: A PHP Error was encountered Severity: Notice Message: Undefined variable: data Filename: register/register_open.php Line Number: 2 I add: die(var_dump($data));

So, $data isn't getting passed to that view. If you pass an array with 'data' as a key, it should work...

I just tested it on my local copy of CI, and it worked. What version of CI are you using?
