Helper References

A helper reference is a reference that points to data created by a helper. For example, when looping through an object using the foreach helper, you can access the value of the current child key by using {{@index}}

Hi, could you please give some examples about the IDs, especially the benefit/where it will be useful?

Thanks

[nebrelbug]

@tafandi great question! Basically, ID's are really helpful in easily accessing references inside scoped helpers. So if you have a really large nest of loops and you want to access the key of the topmost loop from inside the innermost loop, instead of doing this:

{{foreach(obj1)}}
{{foreach(obj2)}}
{{foreach(obj3)}}
{{foreach(obj4)}}
{{@../../../key}}
{{/foreach}}
{{/foreach}}
{{/foreach}}
{{/foreach}}

You can do this:

{{foreach(obj1) loop1}}
{{foreach(obj2)}}
{{foreach(obj3)}}
{{foreach(obj4)}}
{{@loop1:key}}
{{/foreach}}
{{/foreach}}
{{/foreach}}
{{/foreach}}
