F3 Framework Template serve not calling PHP functions

Question

It seems F3 framework doesn't handle php function calls within a page? I have a php navigation bar, which is uniform site-wide. I call up my layout page in my controller class thus: Template::serve('layout.php'). In the layout page, I include the navigation bar thus: <F3:include href="navbar.php" />. Within the navbar (navigation) file, I call a utility function siteUrl which gets the absolute url to a resource e.g. css or .js file. This function is defined in an include file which I include as follows: require_once "lib/globals.php. Within the navbar.php, I use the siteUrl as follows for example:

<img id="logo" alt="logo" src="<?php echo siteUrl('small-logo.png') ?>" /> 

This doesn't seem to work. When I view the generated source of the page, the src section of the img tag is an empty string: "". However, when I call the navigation bar from other pages that are not using the F3 framework (i.e. pages that are not being routed by F3::route. Not all pages of the website are routed using F3), it works fine.

What could be the problem? How could I call a php function from within a php page that is being rendered using Template::serve? It seems the entire content between the <?php ?> tag is not being executed when the page is being served by F3. Echo statements are not being displayed. Thanks for responses.

Answer 1

Template::serve() does not allow PHP. It is a templating engine. There are things you can do. You can define a function using F3::set('sum',function($a,$b){return 1+2;}); and then reference that function in the template with {{@sum(1,2)}}. I would re-read the templating documentation on the fatfree site: http://bcosca.github.com/fatfree/#views-templates

Again, the reason PHP is not working is because you are using Template::serve() and are therefore using the templating features of Fatfree. If you want to use PHP, I believe you can use F3::render() instead and it will render the page, allowing PHP, but you will lose all the templating functionality.

Answer 2

you can use raw php within the template tokens wrapped by curly brakets like this:

<img id="logo" alt="logo" src="{{ siteUrl('small-logo.png') }}" />

it will echo it automatically.

but using F3::set('image.smallLogo',siteUrl('small-logo.png')) to define the image paths and grap them with a simple {{@image.smallLogo}} feels much better.
