Original Post on CI Forum
Hello Collin,
I’ve been studying your template plugin lately, as i was following your guide,
i came across this line of code
$data = array('name' => 'John Smith', 'birthdate' => '11/15/1950');
$this->template->write_view('content', 'user/profile', $data, TRUE);
it was a bit confusing whether in the view files, like
mymastertemplate.php for example, how do i accessthe $data array, does
it have to be $content defined by that first param. a region, or by
$name and $birthdate? ... cuz’ it says there $content will display the
data array? its a bit confusing. Hope you could enlighten me.
Basically thats my problem.

Answer 1

On Template.php library we can see function write_view(). Now, focus on $data = NULL. Now then finds a file of existed data on APPPATH.'views/'.$suggestion.'.php' so I think that $args[0] should be a file which is loaded and break it, than loaded a view template on $data.
function write_view($region, $view, $data = NULL, $overwrite = FALSE)
{
$args = func_get_args();
// Get rid of non-views
unset($args[0], $args[2], $args[3]);
// Do we have more view suggestions?
if (count($args) > 1)
{
foreach ($args as $suggestion)
{
if (file_exists(APPPATH .'views/'. $suggestion . EXT) or file_exists(APPPATH .'views/'. $suggestion))
{
// Just change the $view arg so the rest of our method works as normal
$view = $suggestion;
break;
}
}
}
$content = $this->CI->load->view($view, $data, TRUE);
$this->write($region, $content, $overwrite);
}
In another way, $data should be as array which will response for View template data on Codeigniter library (standard view of CI: $this->CI->load->view(...))
$data = array('name' => 'John Smith', 'birthdate' => '11/15/1950');
$this->template->write_view('content', 'user/profile', $data, TRUE);
On template file '/user/profile.php' use as example:
HTML/PHP template file profile.php:
Your name: <?php echo $data["name"]; ?>
Your name: <?php echo $data["birthdate"]; ?>
And as I see, a CONTENT var must be an ARRAY due to documentation...
$template['default']['regions'] = array(
'header' => array(
'content' => array('<h1>Welcome</h1>','<p>Hello World</p>'), ### <----- AS EXAMPLE
'name' => 'Page Header',
'wrapper' => '<div>',
'attributes' => array('id' => 'header', 'class' => 'clearfix')
)
);
Regions must be defined as template, so if you didn't have header region that didn't work:
$template['default']['regions'] = array(
'header',
'content',
'footer',
);

Simply, he can't acces private access variable _ci_cached_vars which is stored data like $name. RELATED TOPIC: CodeIgniter shared data between calls to load->view
