Hello.

I do know how to use the count feature

if $myarray|@count >0 etc...

I am wondering if its possible to do a 'count' of a sub array ?

$myarray.name1
$myarray.name2.population
$myarray.name3.population
$myarray.name4

Now myarray.name2 & name3 both have a 'population' sub-array within them.

I am already doing a 'foreach' loop to display the main content below... But I am wanting to adda 'header' lime in the table, & need a yes/no answer as to whether 'population' exists in the main table below.


I COULD do another 'foreach' loop to do the 'header' but i'll rather not, as it wastes processing time (will it?)

PS - the 'name' field is not standardised - Ive only used it in the above example. I do not know the name of "name" in advance, but i do know there can be a "population" field / array (did that make sense ?)

Not sure if I know what you want but have you tried something like

[quote="elpmis"]

[code]{if $myarray.name2.population|@count >0}[/code]
[/quote]

Thats ok, if i know "name2" in advance - but I do not.

It could be 20-30 different unknown names..

{if $myarray.name2.population|@count >0}

{if $myarray.biggles.population|@count >0}

{if $myarray.turnips.population|@count >0}

{if $myarray.carrots.population|@count >0}

{if $myarray.mrbig.population|@count >0}

{if $myarray.places.population|@count >0}


I'm guessing theres not a simple 1-liner or so. ? I have it going, with a foreach loop to do this... - But appears inefficient... (but going)

By the way - you should find another method to hide output ... "@" to suppress errors is a real performance eater.

What do you mean ? (looking as to where I have used @).

Original :-

$array.2ndfield.3rdfield

Ive moved on with this. I'm guessing there's no 1-liner command to find if '3rdfield' exists (count >0) without knowing the name of 2ndfield in advance.

We need to do a loop over the whole array & work our way down to the 3rd array.

I've moved on, doing a loop.

but I am interested in the correct way to 'count'..

Why do you use "dozens of other websites" and ignore the only aurthoritative source of information about Smarty?…

Instead of blindly copying the code, you should understand its meaning and write your own code based on provided examples.
Glad you've found the note by yourself though. Please keep it up, you may yet make it past copypaste into a real programming.
