Get specific array in a multidimensional array in Smarty

Question

I have the following multidim array;

[features] => Array
    (
        [0] => Array
            (
                [value] => Foo
                [id_feature] => 9
            )

        [1] => Array
            (
                [value] => Bar
                [id_feature] => 10
            )

    )

Being very new to Smarty and its often butt-backwards approach to things, I have no clue where to begin, if I wanted to get a specific array based on the value of id_feature of that array.

That is to say, I'd need to put into a variable the array that for instance contains "9" for id_feature.

How would I go about this?

Just a suggestion: why not make id_feature the key for the parent array? — Jon Egeland

Love to, but I can't change the content of the array, as it's generated by Prestashop - and I'm looking to just make a theme more than change the behavior of the core. :) — Emphram Stavanger

Try this smarty code:

{foreach from=$features item=f}

  {if $f.id_feature eq 9}

   {$f.value}

   {$f.id_feature}

  {/if}

{/foreach}

What about using in_array?

<?php
function getArray($search) {
   foreach($features as $val) {
      if(in_array($search, $val)){
        return $val;
      }
   }
 }
?>

Provided that you assigned something like this in PHP:

$features = array( 
    array("value" => "Foo", "id_feature" => 9), 
    array("value" => "Bar", "id_feature" => 10) );
$smarty->assign('features', $features);

In Smarty template, {$features[0].value} will give you Foo.

You can also traverse the array using {for} or {foreach} - check documentation http://www.smarty.net/docsv2/en/

Or even use {php} tag to write PHP directly:

{php}
  global $features;
  print_r($features);
{/php}
