I am trying to display the array size of a multi-dimensional array in a Smarty table. However, when using the {array() | @count} it returns Array.

Here's the setup:

First, in PHP two arrays are built:


Code:

<?php
// setup for Smarty and load arrays here
$smarty->assign('parkinglot', $parking);
$smarty->assign('vehicles', $vehicles);

$smarty->display('parkinginfo.tpl');
?>



Where $parking looks like:
Array(1)
1 => Array (3)
floors => "3"
sections => "9"
price => "1.5"

and $vehicles look like:
Array (2)
cars => null
trucks => Array (1)
1 => Array (3)
1 => "A12345"
2 => "B12345"
3 => "C12345"

In the smarty template I want to display a table that shows the number of cars and trucks in a separate table cell:

Code:

{ *Smarty *}
{foreach from=$parkinglot key="space" item="data"}
       
                <th>{$space}</th>                        {* Row number *}
                <td>{if isset($vehicles.cars.$space)}
                        {$vehicles.cars.$space | @count}
                    {else}
                        0
                    {/if}                   
                </td>    {* Cars *}
                <td>{if isset($vehicles.trucks.$space)}
                        {$vehicles.trucks.$space | @count}
                    {else}
                        0
                    {/if}
                </td> {* Trucks *}
        </tr>
{/foreach}


What's peculiar is that the isset($vehicles.trucks.$space) test seems to work just fine. So, my de-referencing of the array seems to work ok in that context, but trying to get count to operate on the same portion of the array results in Array.

Maybe count can't be passed an array where the last "leg" of the array is designated by a variable ($space)? (no errors from the parser, though...)

Any help here is greatly appreciated.

Thanks in advance...

It returns the text 'Array'.

You have to remove the spaces around the pipe sign:

{$vehicles.cars.$space|@count}

Instead of:

{$vehicles.cars.$space | @count}

(I like space too so I just ran into the same problem Wink )
