Passing Data to View - El Forum - 08-28-2012

I have a controller that sends an email, then loads a view:

$data['title'] = 'Contact Us';

Code:
$email_data = array('message' => 'This is the message';

$email_message = $this->load->view('email_template', $email_data, TRUE);

// send email...

// if there was a problem store error message in $data['message']

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

And in my view (contact.php):

Code:
&lt;?php if(!empty($message)) : ?&gt;

&lt;?= $message ?&gt;

&lt;?php endif; ?&gt;

Even if there's no problem sending the email, the

Code:
$message

variable is not empty -- it contains the email message that's passed to the email template.

So, even though the

Code:
$data

array that we're explicitly passing to the view we want to load doesn't contain an index/value for

Code:
'message'

, since there's a different array that does, and is passed to a different view, that variable is then available in a view to which we're not explicitly passing that array.

I realize that a really simple work around is to initialize any indexes of our "final" $data array that may possibly exist in any other $not_data arrays passed to views that may be loaded before loading our "final" view. But should I have to do this? Is this the intended behavior?

Thanks!

CI "caches" view variables in order to make variables available to views embedded inside views. So it's normal for that to happen, but I can see how it may not be what you expect.

You should create an issue, or even a pull request if you have a suggested solution, on Github. See if others have this problem or empathize enough to create a solution if you haven't suggested one.
