John, thanks so much for helping out.
I’ve run the code you suggested, and you can see the results here (under the heading Optional Extras – the other two columns are coded line by line – not ideal): https://bushlapa.storiesandscience.co.za/caravans/goggas/rooimier/
Just to take a step back – what I’d like to achieve is the following:
– Display the field names and values from one field group at a time.
– Exclude any fields that do not have a value.
Here is a snippet of the printed result:
Array
(
[dry_weight] => Array
(
[ID] => 439
[key] => field_5937f37f96261
[label] => Dry weight
[name] => dry_weight
[prefix] => acf
[type] => text
[value] => 620
[menu_order] => 0
[instructions] =>
[required] => 1
[id] =>
[class] =>
[conditional_logic] => 0
[parent] => 303
[wrapper] => Array
(
[width] => 33
[class] =>
[id] =>
)
[_name] => dry_weight
[_prepare] => 0
[_valid] => 1
[default_value] =>
[placeholder] =>
[prepend] =>
[append] => kg
[maxlength] =>
)
[total_length] => Array
(
[ID] => 440
[key] => field_5937f3b496262
[label] => Total length
[name] => total_length
[prefix] => acf
[type] => text
[value] => 3360
[menu_order] => 1
[instructions] =>
[required] => 0
[id] =>
[class] =>
[conditional_logic] => 0
[parent] => 303
[wrapper] => Array
(
[width] => 33
[class] =>
[id] =>
)
[_name] => total_length
[_prepare] => 0
[_valid] => 1
[default_value] =>
[placeholder] =>
[prepend] =>
[append] => mm
[maxlength] =>
)
