RE: [flexcoders] AMFPHP / databinding nested arrays

[dj]

The way you constructed your array might come out like this, but not
sure, looks a little crazy…


myResultObject[0].day.mon.start.100.end.300


Nested Arrays return into Flex as objects.  I haven’t tried nesting
an array as complicated as this, I guess it’s doable – but it
might be better to reorganize your array structure .  I think it will
be easier to read than a big old nested array constructor than in php
if you use the following example, and this is how I do it.


?
$my_array = array();
$my_array[0]['days'] =$some array
$my_array[0]['starts'] =$some_other_array
Return $my_array;
?


//in flex your result arrays work like this...

Var someArray:Array  = myResultObject[0].days
Var someOtherArray:Array  = myResultObject[0].starts


Then you can get your values and organize your arrays which ever way
you like.

Hope this Helps

Subject: [flexcoders] AMFPHP / databinding nested arrays

Hi there,

I guess this is a typical newbie question,  maybe someone could
kindly direct me to a tutorial or sample:

I try to bind e.g. using a charts control to a nested array I receive
from an AMFPHP service.
On the php side I have as an example:
$outputArr[] = array('day' = 'Mon', array('start' = '100', 'end' =
'300'));
$outputArr[] = array('day' = 'Tue', array('start' = '250', 'end' =
'600'));
$outputArr[] = array('day' = 'Wed', array('start' = '500', 'end' =
'600'));
return $outputArr;
..which will deliver the data correctly as I can see from the flex
debugger.

In flex I have eg.:
mx:series
mx:ColumnSeries xField=day yField=??? /
/mx:series
Now, how do I access e.g. the value 'start' to use it for
databinding? Well, 'day.start' does not do the trick : )

I had similar probs using XML for binding, where I wouldnt be able to
access sub-children?
Do I have to somehow wrap the server response into an actionscript
object which I'd have to manually add properties to?

Any hint greatly appreciated!!

Hmmm, why exactly are you sending nested arrays from amfphp? Why can't 
you just send a flat array?
