Quick question on including data in view - El Forum - 12-08-2010

Let's say I'm setting a variable in my controller that I use in my view called "header" to set the title of the page. Assuming that (for some reason) I only wanted to include the header view once, but I wanted to set the page title variable in an <i>if</i> statement after I included the header view, would there be anything wrong with including the data in the content view during the <i>if</i> statement?

In other words:

Code:
$this->load->view('header');

if ($this->form_validation->run() == FALSE)

{

    $this->data['pagetitle'] = "Fail";

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

}

else

{

    $this->data['pagetitle'] = "Not fail";

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

}

$this->load->view('footer');

If "header" view uses $this->data['pagetitle'], is this still legit code? Could I even include the data in the "footer" load?

I would assume that the PHP happens and the variables get tossed into the collection of views prior to getting to the user's browser, but I just want to be sure there's nothing wrong with this.

Thanks!

You mean an actual page title in your html head?

You pass the page title to your view and then use it thus:

Code:
&lt;title&gt;

  &lt;?php if(isset($page_title)) echo $page_title ?&gt;

&lt;/title&gt;

That code is in my header view.

Sorry, I was probably unclear.

I have that aspect functioning in my header view. My question was that if I have, say, three different views (header, content, footer), can I include data that the header view uses in the content view?

Yes you can, but in your example $this->data['pagetitle'] is defined after $this->load->view('header') and is not available in header view. $pagetitle would be available in the footer view though because $this->data['pagetitle'] is defined before that. But remember to pass $this->data to other views also or use $this->load->vars($this->data) which will enable all the variables to all views without sending it separately. For example:

Code:
$data = array('foo' => 'Bar');

$this->load->vars($data);

$this->load->view('header');

$this->load->view('content');

$this->load->view('footer');

Variable $foo would be available in all the views and you would not need to send the array separately to all views that need it. Like this:

Code:
$data = array('foo' => 'Bar');

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

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

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