Smarty在tpl文件中不显示数组值

Question

I want to create an XML file through smarty template. For this, i am passing an array to the template file. This is the code i am using to generate array and to pass.

$correct_answers = explode(",", $answer['answer']);
$smarty->assign('answers', $correct_answers);

The array is generated successfully and i checked it by using print_r() ; But my problem is, it shows empty in the tpl file. If i check the count, it shows 0. I cannot get the array values. This is the template file code.

{assign var = "inc" value="0"}
{section name=answer loop=$answers}
    <simpleChoice identifier="{$answers[answer]}">{$answers[answer]}</simpleChoice>         
    {assign var = "inc" value=$inc+1}
{/section}

I don't know where i went wrong.

Array Structure is,

Array
(
    [0] => Alonso
    [1] => Jenson Button
    [2] => Rubens Barrichello
)

Answer 1

Try this : Instead of section use foreach .

{foreach from=$answers item=answer}
    <simpleChoice identifier="{$answer}">{$answer}</simpleChoice>         
    {assign var = "inc" value=$inc+1}
{/foreach}

This is similar to foreach loop in php.
