If I have an array that looks like this:

Array
(
[Salary] => Array
(
[0-50K] => Array
(
[filterType] => range
[fieldLabel] => 0-50K
[fieldName] => SALARY
[lowerValue] => 0
[upperValue] => 50
[inclusive] => LEFT
)

[50-70K] => Array
(
[filterType] => range
[fieldLabel] => 50-70K
[fieldName] => SALARY
[lowerValue] => 50
[upperValue] => 70
[inclusive] => BOTH
)
)
)


How can I access the key values? Individually, that is. What about the
child array key/values? Individually, that is. In the template, I've
tried:

{$myArray[0]}
{$myArray[0].filterType}
{$myArray[0][0]}

Nothing seems to work. I know how to iterate through the entire array and
display the contents that way, but I don't know how to get the key/value of
just one particular element (and/or any child arrays of that element).

Any help would be greatly appreciated!

thnx,
Christoph

{$myArray.Salary.0-50K.filterType} should work, but the key 0-50K might be
problematic due to the leading numeric character (I haven't tried it). If
it doesn't work, try adding a leading alpha char to those key names.

And if I don't know the key value off hand because the array was generated
dynamically?

As an aside, 2 features that would be really nice when working with arrays
in a smarty template:

* get the total count of the elements w/o having to iterate through the
array
* be able to access the first or last element even if the keys aren't
numeric

thnx,

You can get the count of an array with {$array|@count}

But, you are better off assigning the count if you need it, and also
assigning your keys/index values that make things as simple as possible
in the template. Instead of assuming the template should be able to
traverse your data in any format, instead format your data in a way that
is a easy as possible to traverse and display.

Not very efficient but could do:

{foreach from=$my_array item=arr name=arr_loop}
{if $smarty.foreach.arr_loop.first}
do something for first only
{/if}
{/foreach}
