Getting basepath from view in zend framework

Question

Case: you're developing a site with Zend Framework and need relative links to the folder the webapp is deployed in. I.e. mysite.com/folder online and localhost:8080 under development.

The following works nice in controllers regardless of deployed location:

$this->_helper->redirector->gotoSimple($action, $controller, $module, $params);

And the following inside a viewscript, ie. index.phtml:

<a href="<?php echo $this->url(array('controller'=>'index', 'action' => 'index'), null, true); ?>">

But how do I get the correct basepath when linking to images or stylesheets? (in a layout.phtml file, for example):

<img src='<?php echo WHAT_TO_TYPE_HERE; ?>images/logo.png' />

and

$this->headLink()->appendStylesheet( WHAT_TO_TYPE_HERE . 'css/default.css');

WHAT_TO_TYPE_HERE should be replaced with something that gives

<img src="/folder/images/logo.png />` on mysite.com and `<img src="/images/logo.png />

on localhost

You can get the base url from the Front Controller Zend_Controller_Front::getInstance()->getBaseUrl();. I wrap that in a view helper

class My_View_Helper_BaseUrl 
{   
    /**
     *  Get base url
     * 
     * @return string
     */
    public function baseUrl()
    {
        return rtrim(Zend_Controller_Front::getInstance()->getBaseUrl(),'/');
    }

}

So in the html markup you have something like <img src="<?php echo $this->baseUrl();?>/images/logo.png"/> The trailing slash is stripped out in the helper so that when the application isn't run in a sub folder (baseUrl is blank in that case) the path will still work.

i agree with the base URL helper, but i think that having another one for images that extends this one is a much better approach – Hawaiian

In case anyone wants to know the best way and doesn't want to waste 2 hours searching Zend/Google. There is a view helper to do that.

$this->view->serverUrl();

Correction: $this->serverUrl(); – Stinking

Answer 3

If do you want to host name in your layout file so print this and get your HOST name:

echo $this->serverUrl().$this->baseUrl()

This is my baseUrl helper:

class Zend_View_Helper_BaseUrl extends Zend_View_Helper_Abstract {
    public function baseUrl() {
        $protocol = isset($_SERVER['HTTPS']) ? 'https' : 'http';
        $server = $_SERVER['HTTP_HOST'];
        $port = $_SERVER['SERVER_PORT'] != 80 ? ":{$_SERVER['SERVER_PORT']}" : '';
        $path = rtrim(dirname($_SERVER['SCRIPT_NAME']), '/\\') . '/';
        return "$protocol://$server$port$path";
    }
}

use it like this: <base href="<?= $this->baseUrl() ?>" /> – Pentane

        // Remove trailing slashes
        if(NULL !== $file) {
            $file = '/' . ltrim($file, '/\\');
        }else{

        }
        $baseUrl = $protocol.'://'.$subdomain.'.'.$domain.$port.$file;
        return $baseUrl;
    }
}

This worked for me:

echo $this->serverUrl() . $this->url()
