How to use display() on more than one array

Question

I am trying to pass more than one array to the Twig display() method. My code contains several functions returning arrays. I do have one parent template (parent.phtml) and several child templates (child_n.phtml) which are extending the parent template.

This is the relevant part of index.php:

$template = $twig->loadTemplate('child_1.phtml');
$template->display(function_1());

Declaration of the Twig environment etc. is happening in another file which is included.

With the code above everything works fine. But what I want to do, is displaying more than one array. So I have tried

$template->display(function_1(), function_2());

This does not work. When using $template->display(); twice, the parent template is being displayed twice...

So what might be a solution?

Answer 1

You have several ways to solve your problem :

1) If your function_1() and function_2() do return arrays with distinct keys, you can use array_merge to merge all arrays.

$template->display(array_merge(function_1(), function_2()));

So if function_1() returns array("a" => 42) and function_2() returns array("b" => 84) , you can use {{ a }} and {{ b }} in your twig file to access your values.

2) If your function_1() and function_2() do return arrays with some similar keys, you need to give a name to them :

$twigVars = array();
$twigVars['array1'] = function_1();
$twigVars['array2'] = function_2();
$template->display($twigVars);

So if function_1() returns array("a" => 42) and function_2() returns array("a" => 84) , you can use {{ array1.a }} to access 42 and {{ array2.a }} to access 84 in your twig file.
