Looping over arrays

To be able to include several array values in the output, you must use the #foreach directive to loop over arrays (see The #foreach directive).

Looping over all values in a one dimensional array

If you do not know in advance how many values there are in an array, you can create a #foreach directive that loops over all values in a one dimensional array.

Example 15

Looping over all values in a one dimensional array

In this example, the #foreach directive loops over all values of the array $array, and writes the values to the output. The variable $array is defined in a StreamServe script.

#foreach($j in $variables.array)

$j

#end

 

Looping over an array using a fixed range

You can also create a #foreach directive that loops over a fixed number of values of an array.

Example 16

Looping over an array using a fixed range

In this example, the #foreach directive loops over the first four values of the array $array, and writes the values to the output.

#foreach($j in [0..3])

$variables.array[$j]

#end

 

Looping over an array using a variable range

In the StreamServe script you can create a counter variable that defines the full range of an array, and then use this counter variable to define the range to loop over.

Example 17

Looping over an array using a variable range

In this example, the #foreach directive loops over the range [0..$counter] of the array $array, and writes the values to the output. The variables $array and $counter are defined in a StreamServe script.

#foreach($j in [0..$variables.counter])

$variables.array[$j]

#end
