Hi,

I have an issue with an include() in my views.

Here is my project tree :

In my News controller I have :

PHP Code:
...  $this->load->view('news/add'); 

And in my view news/add I have :

Code:
<?php  include "../template/core/template_top.php" ?>

...

<?php include "../template/core/template_bottom.php" ?>

And i got this error :

Code:
Message: include(../template/core/template_top.php): failed to open stream: No such file or directory

...

Message: include(): Failed opening '../template/core/template_top.php' for inclusion (include_path='.:/Applications/XAMPP/xamppfiles/lib/php')

Why ? My path is right, no ?
I'm lost.
Can anyone help please ?
Thank you !

You can load another view inside a view.

View: news/add.php

PHP Code:
<?php $this->load->view('template/header');?>
...
...
<?php $this->load->view('template/footer');?>

This way, though, you get a lot of repeating code. Because every view must embed a header and footer. An alternative way is make a function in MY_Controller (that extends the CI_Controller):

PHP Code:
public function _render_page($view, $data) {
$this->load->view('template/header');
$this->load->view($view,$data);
$this->load->view('template/footer');
} 

Now, from your controller, you can do this:

PHP Code:
$this->_render_page('news/add', $data);  //data is an array with variables you want to use in the view

Thanks that's look great !

And how to do if I want to add a different <title> and different css links in my pages ? Can we do that with this way ?

I have done this :

MY_Controller :

PHP Code:
class My_Controller extends CI_Controller
{
    public function render($view, $pageTitle = NULL, $data = NULL, $headElements = ['elements' => NULL] )
    {
        $this->load->view('template/header', $pageTitle);
        $this->load->view('template/head_elements', $headElements);
        $this->load->view($view, $data);
        $this->load->view('template/footer');
    }
} 

Controller News :

PHP Code:
class News extends MY_Controller {

    public function index()
    {
        $elements = [
            'elements' => [
                '<link rel="stylesheet" href="www.google.ch">'
            ]
        ];

        $this->render('news/index', ['pageTitle' => 'Hello'], ['texte' => 'blablabla'], $elements);
    }
} 

My template folder in views :
- header
- head_elements
- footer
header :

Code:
<!DOCTYPE html>

<html>

    <head>

        <meta charset="utf-8">

        <title><?php echo $pageTitle ?></title>

head_elements :

Code:
<?php

    if( $elements != NULL)

    {

        foreach ( $elements as $element)

        {

            echo $element;

        }

    }

?>

</head>

<body>

<header>

    Header de mon site

</header>

footer :

Code:
   <footer>

        Footer de mon site

    </footer>

</body>

</html>

Explanation:
1) $headElements in MY_Controller has an index 'elements' because I want to call it in my head_elements template to test if it's avoid
2) I have separated header and head_elements in the template because it's rare to add css links or meta so I didn't want to pollute all my render function in my controllers with an array complicated like array( 'pageTitle' => 'Title', 'elements' => NULL)

I dont think it's the best solution, how can I improve it ?

Thanks for your help !

An advice ?

I have built my own Assets library. It's autoloaded in autoload.php, so it's available for all pages.
The library his public arrays like $stylesheets and $javascripts.
And methods like add_stylesheet($path), and add_javascript($path).
But also: output_stylesheets(), which just returns a string with all stylesheets in the appropriate format.

In my controller, I do this:

PHP Code:
$this->assets->add_stylesheet( base_url() . 'assets/css/example.css');
$this->assets->add_javascript( base_url() . 'assets/js/example.js'); 

In my header view I have this:

PHP Code:
<head>
<?= $this->assets->output_stylesheets();?>
<?= $this->assets->output_javascripts();?>
</head> 

The method output_stylesheets in the library is like this:

PHP Code:
public function output_stylesheets()
{
    if (empty($this->stylesheets)) return NULL;
    $str = '';
    foreach($this->stylesheets AS $item){
        $str .= '<link rel="stylesheet" href="' . $item . '" type="text/css" />' . "\n";
    }    
    return $str;
} 

For me, this is as flexible as I need it.

I use many includes within my views also depending on passed parameters different HTML headers are loaded (a special one for AmpProject compatible pages.)

Recently CodeIgniter simplified includes by declaring a VIEWPATH constant in index.php.

// view file common to many web-pages
if( isset( $ampOk ) ):
require VIEWPATH ."template/core/_header-amp.php";
else:
// load non-amp version
endif;
