{{macro}} usually works with plain PHP scalar values or arrays. However, if you want your objects to be fully supported in {{macro}} as well, make sure that your object supports ArrayAccess(in case of accessing attributes using dotted syntax) or Iterator(in case of iteration).
There are two common ways to make some data appear inside a template:
{{macro}} supports both of these approaches.
lmbMacroTemplate has set($variable_name, $value) method that sets global variable $variable_name in the template. This variable will be available in template as {$#variable_name} or {$this→variable_name} expressions.
For example:
$macro = new lmbMacroTemplate('page.phtml'); $macro->set('title', 'Hello');
To render 'title' in {{macro}} template we can use the following expression:
{$#title}
There is also lmbMacroTemplate :: setVars($associative_array) that is equal to several set() method calls for every element of $associative_array. Note: setVars() removes previously assigned variables.
You can also use arbitrary PHP blocks right in {{macro}} templates to fetch data, e.g.:
<? $products = lmbActiveRecord :: find('Product'); ?> {{list using='$products' as="$product"}} <ul> {{list:item}} <li>{$product.title}</li> {{list:item}} </ul> {{/list}}
If you create an application based on WEB_APP package of Limb3, you may be interested to know that template can access all attributes of the currently executed controller(just like you called lmbMacroTemplate :: set() for every controller attribute).
For example:
class MyController extends lmbController { function doDisplay() { $this->title = 'Hello'; } }
In the corresponding {{macro}} template $title attribute will be available as:
{$#title}
{{macro}} has only 2 contexts or data scopes:
Rendering always starts with render() method of the generated PHP class. Some tags like include or apply generate their code into separate methods and thus create other local scopes. {{include}} and {{apply}} allow to pass any variables into their local scopes with any number of extra attributes (see descriptions of these tags).
