Hello to all!

Is there any straight and obvious way to count the number of elements
in some array???

maybe I'm blind, but can't find that in the manual, and the only way
out I've found so far is like this.

{foreach from=$some_arr item=$i name="my_foreach"}{/foreach}
Number of elements: {$smarty.foreach.my_foreach.total}

Looks horribly stupid So, any other way?

Best regards
Dmitriy

That FAQ page Monte Ohrt sent has lots of useful info.

Remember, any PHP function can be used in a smarty template. The simple
array functions are handy in a pinch.

{$array|@count}
{$array|@min}
{$array|@max}
{$array|@array_sum}

the order is weird for functions that expect multiple params especially
the needle, haystack array functions. you have to send the needle and
then put the array as the param to the function like so:

{$value|@in_array:$array}

some functions just don't make any sense for use in the templates.

Q: How do I count the number of elements in an array?
A:

{$array|@count}
The "@" applies the modifier directly to the array instead of each
individual element.
