Right now i'm doing a foreach loop.

The value of the loop is another sub-array, with ONE key/value combination.

is there a quick way of finding the key/value "values" quickly ? the only way i can figure it out is by doing another foreach loop. but this seems cumbersome.

Code:

{foreach from=$levels key=k item=v}
<tr><td>{$k}</td><td>{$stats.NAME.$k}</td><td>{$stats.NAME2.$k}</td><td>{$stats.NAME3.$k}</td></tr>
{/foreach}



$stats is ok - the key to $stats is taken from $levels. This is correct. within $stats are further keys - NAME, NAME2, NAME3,

$stats.NAME.$k produces a sub-array with one key/combintion. i do not know the "key" in advance.

is there a way, to just say "display the 1st key/value combination found"

Cumbersome? To whom? I would let the computer do it.

Key-value or just value?
Also, where are stats came from, if you only have $v ?

ive got the $stats as a separate array. the keys/value combination is also the key in $stats.

in the above script - it will ALWAYS have a sub-array with one key-value set.

just wondering if theres a quick way of extracting them - without doing a foreach loop on the sub-array.

I could just do $v.0 to get the 1st value of $v - however the keys in $v are not numerical, & i cant just go $v.1 $v.2 etc.. as i do not know the keys in advance.

You could try if Smarty will allow the use of PHP function each().
Code:
{{$v|each}[0]}
should get you the key of the array element in $v that the array pointer is currently sitting at. The value of the array element referenced is at index [1].

I haven't tried this.

each() is deprecated.

foreach is quick. All other methods are slower.
