如何在模板中获取Kohana base_url

Question

In Kohana 3 bootstrap.php one can define base_url :

Kohana::init(array(
    'base_url'   => '/foo/',
));

This usually means also moving the /js/ , /css/ and other media to that base dir like /foo/js/ , /foo/css/ . My question is not to discuss good or bad of such.

Is there a built-in way in Kohana to access the base_url from a template (just like in Django you can use {{ MEDIA_URL }}css/ )?

Answer 1

You can output the base url as using URL::base :

<?php echo URL::base(); ?>

If you're outputting a url relative to that you probably want URL::site :

<?php echo URL::site('css/'); ?>

Kohana 3 template controllers use the View class to render templates. Views are normal php files and have no special syntax, so just use the normal <?php ... ?> tags as above. The View class allows you to declare variables for use in that view, before you render it.

Answer 2

One good way is that in your layout view, in the head of the HTML you put near the <title> tag:

<base href="<?php echo URL::base(TRUE) ?>">

and then, you load your assets this way:

<img src="assets/images/img.jpg" alt="">

The HTML <base> tag is a way of defining a base URL for all the assets in the page. This way you load your image located at /foo/assets/images/img.jpg without making a URL::base() call in every tag. I hope it helps.
