set-block

Summary

Redirects the output from a block of template code to a string.

Usage

{set-block variable=$variable [ name=name ] [ scope=scope ]}
...
{/set-block}

Parameters

Name	Type	Description	Required
variable	string	The name of the variable (with dollar sign).	Yes.
name	string	The name of the target namespace.	No.
scope	string	The scope ("global", "root" or "relative").	No.

Description

This mechanism will silently process all template code which is encapsulated by "{set-block ...}" and "{/set-block}". It will not produce any actual output. Instead, the generated output will be assigned to a variable specified by the "variable" parameter (as a string). If the variable does not exist, it will be automatically created. If the same target variable is used in several blocks, its contents will be overwritten every time a new block is processed.

Examples

Example 1

{set-block variable=$example}
    {def $test=array( 'x', 'y', 'z' )}
    Hello world - {$test[1]}
{/set-block}
...
{$example}

The code which is encapsulated by "set-block" will not produce any output. Instead, the output will be put into a string called $example. When this variable is accessed directly, the following output will be produced: "Hello world - y".

Example 2

{set-block scope=root variable=cache_ttl}0{/set-block}

This will put zero into the "cache_ttl" global variable and thus disable view caching for this page.
