variable variable name

[v.]

I have a session variable that I need to output in a view.

Let's say the key is

@SESSION.result.parent_age

A view is included dynamically where "parent" is set in the calling view, like this:

<set famMember="parent" />
<include href="age.htm" />

In age.htm I need to ouput the resulting @SESSION.result.parent_age, but I fail to do so.

I have tried

<set age="@SESSION.result"{{ @famMember}}"_age" /> //also tried with concatenating dots
{{ @age}}

and

<set age="{{ '@SESSION.result' .  @famMember. '_age'}}" />

and all combinations with or without colnos and concatenating dots, but I always get a 500 error

 

{{ @SESSION.result.@famMember.'_age' }}

outputs 'Arrayparent_age'. I understand why this would happen, but how do I get the correct value?

To be clear: in this particular case there are 40 famMembers with their corresponding _age, so I really need to get the values dynamically.

Hi!

You are close...

You could try:

<set age="{{ @SESSION.result[@famMember . '_age'] }}">

or directly:

{{ @SESSION.result[@famMember . '_age'] }}

because you are building the index into the array dynamically.

I'm assuming @SESSION.result is an associative array.

Thanks yet again doc, you're a life saver.

The amount of beers I owe you (and also ved) will destroy your liver :)
