Template helpers

Koala provides a set of helper classes for html based on Zend_View helpers.
You can find the full list under /Kwf/View/Helper/ or you can search for them in our docs.

Extend another twig file

Extend a component's Component.twig file:

{% extends renderer.getComponentTemplate("MyComponent") %}

Extend any twig file:

{% extends "path/to/my/template.twig" %}

Render an image-tag

{{ renderer.image("/assets/web/images/myImg.png", "Alt text")) }}

Render an image-tag with html-attributes and inline styles:
This should only be used if styling with css is not possible, for instance in HTML-Emails.

{{ renderer.image('/assets/web/images/myImg.png', "Alt text", {'width': 100, 'height': 40, 'border': 0, 'style': 'vertical-align: middle; text-decoration: none;'}) }}

Render a link to a component's page

{{ renderer.componentLink(targetComponent, "Link text")) }}

Render a link to a component's page with inline styles:
This should only be used if styling with css is not possible, for instance in HTML-Emails.

{{ renderer.componentLink(targetComponent, "Link Text", {'style': 'text-decoration: none;'}) }}

This encodes an email address, so it cannot be found too easily by crawlers looking for spam targets.

{{ "koal@koala-framework.org"|mailLink }}

This will be converted to the following HTML.
As soon as JS is loaded it will be decoded and will function like any other mailto-link.

<a href="mailto:koal(kwfat)koala-framework(kwfdot)org">
    <span class="kwfEncodedMail">koal(kwfat)koala-framework(kwfdot)org</span>
</a>
