How to assign an array within a smarty template file?

Question

I was wondering if it was possible to assign an array to a variable within a Smarty template file? I have tried this

{assign var='file' value = array('dir','doc','exe')}

But when I print out the array it produces this:

array(\'dir\',\'doc\',\'exe\') 

How can I stop Smarty escaping the array values?

I have ran through this problem and came up with a solution earlier. The solution I came up with is here – Assail

Answer 1

{php}
  $this->assign("array", array('dir','doc','exe'));
{/php}

{foreach from=$array item=item}
  {$item}
{/foreach}

From Smarty v.3 new syntax is available

{$array = ['item1','item2',$item3]}

see for more details : http://www.smarty.net/docs/en/language.syntax.variables.tpl

If you use {php} then what is the meaning of using smarty? You should not use {php} inside template until it is the only option. @Aceae 's solution is perfect – Petasus

Make sure NOT to put a comma (,) behind the last element. I was copying the array from php which was causing an syntax error. – Unwritten

It is also possible to assign variable manually to template vars: {php}$this->_tpl_vars['my_array'] = ['var1', 'var2'];{/php} – Afterburning

Answer 2

I just found another answer here that allows you to do this without the use of {php} tags (recommended by Smarty)

{assign var='icon' value=','|explode:"dir,doc,exe"}

still open to more ideas though...

this method do not allow to assign associative array – Maryrosemarys

+1 - thanks. This was exactly what we needed to address an issue in our hacky third-party CMS. – Needless

For version 3 of smarty see Mituha's answer. – Bargeboard

This answers precisely what the question asks. – Countershaft

Is there a function I could use to get an empty array? – Entreat

Answer 3

what about {$system=['freebsd','windows','macosx','linux']}?

This works in Smarty v3: smarty.net/docs/en/language.syntax.variables.tpl – Bargeboard

Answer 4

its not right way to write a code with in smarty template file. you should create a array in php and then get the values from smarty.

This is the right way to create a standard development code. like.

PHP:

public function arrSam(){
    $colors = array( 0 => '#1f1f1f', 1 => '#696969', 2 => '#878787', 3 => '#b4b4b4', 4 => '#d2d2d2', 5 => '#f0f0f0', 6 => '#ffffff');
    $smarty->assign('colors', $colors);
}

Smarty:

{assign var=colors value=$smarty->arrSam()}
{$colors|print_r}

Answer 5

$smarty->assign("lat",$lat);

{foreach $lat as $latlongval}
    {assign var="myArray" value=","|explode:$latlongval} 
    {$myArray['0']}
    {$myArray['1']}
{/foreach}
