Smarty check selected checkboxes using array_search

I am trying to check checkboxes based on values in a smarty array.

In my php

$smarty->assign('locations_array',array(4,6,9,7));

I want to search through the array and if there is a match check the checkbox. Here is what I have tried in my template but I can't get it to work.I'm not sure how I can pass array_search the needle and haystack that it requires?

{foreach $locations as $x}
   {if $x.id == $x.id|@array_search:$locations_array}
   <label><input checked type="checkbox" name="locations[]" value="{$x.id}"/>{$x.title}</label>
   {else}
     <label><input type="checkbox" name="locations[]" value="{$x.id}" />{$x.title</label>
   {/if}
{/foreach}

Is this possible without creating a custom function?

i didnt works with array_search but i have some simply solution for your issue. you can check your checkbox value with the locations_array in the foreach loop.

 **$i = 0;**
        {foreach $locations as $x}
           **{if $x.id == $locations_array[$i]}**
           <label><input checked type="checkbox" name="locations[]" value="{$x.id}"/>{$x.title}</label>
           {else}
             <label><input type="checkbox" name="locations[]" value="{$x.id}" />{$x.title</label>
           {/if}
**$i++;**
        {/foreach}

For reference I think that this is the correct syntax when using array_search. 

 {if $x.id|array_search:$locations_array}

where $x.id is the needle and $locations_array is the array haystack.
I decided to go for a different approach based on eknals feedback

Without actually answering your main question (I don't know whether you can pass two vars to the function from the template), this could all be avoided by making a new array instead of $locations in the php file. Just looking at your posted code, you would want each element to have three sub-elements: title, id, and checked. This way you can avoid having to compare across arrays in the template side, and you can also avoid having to write a custom function.
