I need to declare some data right in the template. This works fine:

Code:
{$x = ['a' => 100, 'b' => 200]}
{var_dump($x)}


Yelds:

Code:
array(2) {
  ["a"]=>
  int(100)
  ["b"]=>
  int(200)
}


However, the data became too long, so I decided to move them to a separate file, lets name it data.tpl:

Code:
{['a' => 100, 'b' => 200]}


and include that as a template:

Code:
{include "data.tpl" assign="y"}
{var_dump($y)}


This results in

Code:
string(5) "Array"


How can I get actual array to the variable?

The data.tpl template does generate any displayable output. That is, nothing gets displayed from it in its own right.

Try your experiments assuming the scope of $x in data.tpl can be seen by the including parent.

I tried the following:

data.tpl:

Code:
{$y = ['a' => 100, 'b' => 200]}


Then:

Code:
{include file="data.tpl"}
{var_dump($y)}


It yelds NULL. So I don't quite understand what "scope of $x in data.tpl can be seen by the including parent" means Sad


===========================

To make things clear. Actually, I need this:

Code:
{$y = require("data.php")}


But it says unknown function "require"'.

The whole issue is how to acheive this - getting array data from a standalone file into a variable.

Example 7.11 should be your solution. See the docs regarding {assign}.

Alternatively, example 7.48 will also work. See the docs regarding {include}.

bsmither, thank you very much. That's what I was looking for.

I ended up using scope in {include} (7.48 ) due to shorter form of the corresponding {assign}:

data.tpl:

Code:
{$y = ['a' => 100, 'b' => 200]}


Code:
{include file="data.tpl" scope="root"}


scope="root" (section 7.12) fits my needs even better.
