I'm using CodeIgniter. I want to load views inside of other views. How can I do this?
Example:
Let's say I have a "view" called "CommentWall". In CommentWall, I want a bunch of "Comment" views. I use the view for "comment" all over my site!
How can I do this? It seems CodeIgniter only allows me to load views sequentially, which is sort of strange considering I use reusable views INSIDE of other views!
Can I do a $this->load->view('comment'); inside of my view for CommentWall? Or is there some other way to have reusuable views contained inside a view?
You can do it easily, just load the main view, for example CommentWall from the controller
$this->load->view('CommentWall');
To add child views in CommentWall view you can add following line inside your CommentWall view
$this->view('Comment');
For example, if you load CommentWall view from your controller like this
$data['comments'][] = 'Comment one';
$data['comments'][] = 'Comment two';
// load the parrent view
$this->load->view('CommentWall', $data);
Now in the CommentWall (parent view), if you put this
foreach ($comments as $comment) {
$this->view('Comment', array('comment' => $comment));
}
And in your Comment (child view) if you have this
echo $comment . '<br />';
Then you should get output something like this
Comment one
Comment two
Update : Alos, check this answer.
Try
class Main extends CI_Controller {
function __construct()
{
parent::__construct();
$data->comments =$this->load->view('comment');
$this->load->vars($data);
}
And in every view try
echo $comments;
Just load the "Comment" vies as string in controller and pass it to "CommentWall" view.
You can do it like this:
//Controller:
public function load_comment_wall($param) {
$comments_view = ""; //String that holds comment views
//here load the comments for this wall as follows:
//assuming $comment_ids is array of id's of comment to be put in this wall...
foreach($comment_ids as $comment_id) {
$temp = $this->load->view("comment",array('comment_id'=>$comment_id),TRUE); //Setting last parameter to TRUE will returns the view as String
$comments_view = $comment_views.$temp;
}
$data['comments'] = $comments_view;
//load comment wall
$this->load->view('comment_wall',$data);
}
//In Comment wall View, add the following line
echo $comments;

My boss told me make dry navigation dont use repetitive code, for navigation i am trying to extend CI_Controler and with construct load header nav, body, footer files.
My question is when i create new controller and when i try to load different view files, how to achive that???
my extended controler
class MY_Controller extends CI_Controller
{
public function __construct() {
parent::__construct();
$this->load->view('view_header');
$this->load->view('includes/nav_home');
$this->load->view('view_home');
$this->load->view('view_footer');
}
}
and later when i am creating new controler how to load diffrent view files
class Pages extends MY_Controller
{
public function __construct() {
$this->load->view('includes/nav_new_view');
$
}
}
You can create a template library yourself. For example :
function template($view_name,$view_data){
//below will return html string from view name
$data['content'] = $this->load->view($view_name,$view_data,true)
//load main template view and pass the html string to main template
$this->load->view('main_template',$data);
}
In main template, just echo $content
If I understand your question, you're trying to achieve a template situation. For this, the best way is to actually call your templates view files within a primary page view. What I mean is your controller function (not the constructor, an actual class function representing a page) should call a primary view such as
$this->load->view('page1', $this->data);
and within that file, you call
$this->load->view('nav', $this->data);
then your content and then
$this->load->view('footer', $this->data);
You would then repeat the process for page 2 where in your controller's page2 function, you would call
$this->load->view('page2', $this->data);
and your page2 view file is almost identical to page1 except you use your page 2 content in that area.
You could even use a single template view file and pass it a $content variable (which obviously changes per page) and call
$this->load->view('template', $this->data);
I have simple line, but it doesn't work.
$this->getView($input->get('my_wiew', 'Sites', 'CMD'), 'HTML');
//some code
parent::display();
If i simple go to the url index.php?option=com_my_component&view=sites i get my view, but by default it doesn't want to load.
$view = $this->getView('view_name', 'html'); //get the view
$view->assignRef('data', $data_from_model); // assign data from the model
$view->display(); // display the view

is there any way to load a view (for header or footer) on every function (in a controller)? I have a couple of if/else statements there and it would be a pain to change it all when I'll need to.
Yes, you can load the view in the __construct function at the top of your controller. Take
a look at the PHP manual on Constructors
function __construct()
{
parent::__construct();
$this->load>-view('your_view');
}
If the header and footer are going to be constant and required components for the visual part of your site, but you may want to load a different content portion between your header and footer, then you can make a function that will take an argument.
private function doViews($argument)
{
$this->load->view('header');
$this->load->view($argument);
$this->load->view('footer');
return NULL;
}
You may want to have an array of available views inside the doViews function in order to do proper validation that the file exists. Then you simply call the function in each method in your controller like this:
$this->doViews('main_content');
You should try using a Template library like this: https://github.com/philsturgeon/codeigniter-template
Then all you need to is put this in the controller (can be in __construct or within a method)
$this->template->set_partial('header', 'layouts/header');
$this->template->set_partial('footer', 'layouts/footer');
$this->template->set_partial('sidebar', 'layouts/sidebar');
Then to send data like you do with a view:
$this->template->build('create', $this->data);
you could create your main_view ... as a master page that already has a structure:
main_view.php
$this->load>-view('header');
<?php //get content here
?>
$this->load>-view('footer');
If you want to change something in the header or footer (through a statement) you can add content:
function __construct()
{
parent::__construct();
$data['footer'] = ($a == 'foo') ? 'footer one' : 'footer two';
$data_to_main = $this->load->view('template/footer', $data, TRUE);
$data_to_main = 'others';
$this->load>-view('main_view', $data_to_main);
}
Ive been working with CI and I saw on the website of CI you can load a view as a variable part of the data you send to the "main" view, so, according the site (that says a lot of things, and many are not like they say ...ej pagination and others) i did something like this
$data['menu'] = $this->load->view('menu');
$this->load->view ('home',data);
the result of this is that I get an echo of the menu in the top of the site (before starts my body and all) and where should be its nothing, like if were printed before everything... I have no idea honestly of this problem, did anybody had the same problem before?
Two ways of doing this:
Load it in advance (like you're doing) and pass to the other view
<?php
// the "TRUE" argument tells it to return the content, rather than display it immediately
$data['menu'] = $this->load->view('menu', NULL, TRUE);
$this->load->view ('home', $data);
Load a view "from within" a view:
<?php
// put this in the controller
$this->load->view('home');
// put this in /application/views/home.php
$this->view('menu');
echo 'Other home content';
Create a helper function
function loadView($view,$data = null){
$CI = get_instance();
return $CI->load->view($view,$data);
}
Load the helper in the controller, then use the function in your view to load another one.
<?php
...
echo loadView('secondView',$data); // $data array
...
?>
Real basic CI question here, which I cant find anything on in the documentation. I think I may need some further configuration?? I have a function which loads a view and it works correctly, but when I send it parameters its doesn't load the view, any ideas??
Heres code with params (view does not load)
function grid($height,$width)
{
echo $height."x".$width;
$this->load->view("grid");
}
and here's without (view does load)
function grid()
{
//echo $height."x".$width;
$this->load->view("grid");
}
So Height and width is the only thing that echos in the first example, in the second the view is loaded.
Thanks ahead of time!
You are supposed to have your controller pass parameters to the view as an array:
function grid($height,$width)
{
$data = array();
$data['height'] = $height;
$data['width'] = $width;
$this->load->view("grid", $data);
}
Then your view can render them:
echo $height."x".$width;
This allows for a clean separation of concerns between the Controller and View objects.
For more information see the section Adding Dynamic Data to the View in the CI User Guide.
