[PHP] Problem receiving POSTed data
Hi everyone,
So, I'm trying to receive POSTed data which is being sent from Flash
structured as a nested array pictured (conceptually):
id contains (a, b, c)
a contains (prop1 = a1, prop2 = a2, ...)
b contains (prop1 = b1, prop2 = b2, ...)
c contains (prop1 = c1, prop2 = c2, ...)
where a1, a2, b1, b2, c1, c2 are values stored in the keys prop1, prop2 etc.
of their respective arrays. That's the conceptual structure, but that isn't
how the information is passed to PHP from Flash. In Flash (which uses .
notation for arrays), the data is packaged with a LoadVars object (for those
who care) as follows:
postObject.id1
postObject.id1.prop1 = a1
postObject.id1.prop2 = a2
...
postObject.id2.prop1 = b1
postObject.id2.prop2 = b2
...
etc.
I *think* this data *should be* received by PHP (with dots converted to
_ since that's what I've read php does) in the $_POST array as follows:
$_POST contains (id1 - a, id1_prop1 - a1, id1_prop2 - a2, ..., id2 - b,
id2_prop1 - b1, id2_prop2 - b2, ...)
However, that's not what I appear to be getting from the $_POST array. When
I run this code:
/*/
$data = $_POST;
$stuff = \n \n Post contains:;
foreach($data as $prop = $val) {
$stuff .= \n {$prop}: {$val};
}
/*/
and write $stuff to a .txt file, I get the following output:
Post contains:
id1: a
id2: b
id3: c
and that's it! No information at all about id1_prop1, id1_prop2, id2_prop1,
etc etc.
I am really stuck at this point. Does anyone know how multidimensional
information is passed to the $_POST variable? I know it can be done with
HTML forms and arrays, but I'm using flash and so I think my
multidimensional array of information simply gets flattened into a
one-dimensional array when POSTed as a described above (since Flash uses dot
notation for arrays and php changes dots to underscores and just makes it
one long variable name). And that would work fine if that's what it was
doing, but, for some reason, $_POST doesn't seem to be receiving the second
array dimension at all which contains all of my property information (which
should have been flattened into the first dimension).
If that's doesn't make any sense please let me know and I will attempt to
clarify. Otherwise, any and all help is very much appreciated!

Re: [PHP] Problem receiving POSTed data
Hang on - my php code may be working fine. It might be a problem with my
actionscript code - particularly that the LoadVars object I'm using to send
the data might not be able to take multidimensional data (though it
definitely does not say that *anywhere* in the documentation!!). Stupid
actionscript documentation.
Raphael, here is the code I am using (I am iterating through all of the
movieclips in my flash doc and gathering data on their name and position):
/*/
for(var i in _level0) {
if(typeof(_level0[i]) == movieclip) {
data_lv[i] = _level0[i];
data_lv[i].id = _level0[i]._name;
data_lv[i].x = _level0[i]._x;
data_lv[i].y = _level0[i]._y;
}
}
data_lv.sendAndLoad(myScript.php, data_lv, POST);
/**/
The odd thing is that I print out the contents of data_lv and everything is
there as expected in multidimensional form so I thought that was working
fine, but someone on a flash message board just posted saying they thought
LoadVars objects could not handle multidimensional data. So maybe even
though the contents of the object print as expected, it doesn't send as
expected. I'll try this in a completely one-dimensional array from flash to
php and see if it works. If it does, I'll let everyone know.

Did you explicitly checked if the id1 'a' prop isn´t an array?
Can you post your ActionScript codemaybe it´ll help!
:D
Good Luck

PHP does pretty minimal munging of the POST data.
It's unlikely that Flash is sending what you think it's sending.
Even if it is, you have two options:
1. Use HTTP_RAW_POST_DATA (turn it on in PHP) and write your own Flash
array parser in PHP.
2. Convince Flash to POST data more like PHP wants it:
id[a][prop1]=a1id[a][prop2]=a2id[b][prop1]=b1...
#2 will probably be WAY easier, unless Flash is even more broken than
I think. And I think Flash is pretty broken. :-)

Re: [PHP] Problem receiving POSTed data
Problem solved: it was indeed that the flash object did not like
multidimensional data.
I didn't change my PHP code one little bit. But I changed my my
ActionScript code to write the data in a 1-dimensional form as follows:
/*/
for(var i in _level0) {
if(typeof(_level0[i]) == movieclip) {
data_lv[i + _path] = _level0[i];
data_lv[i + _id] = _level0[i]._name;
data_lv[i + _x] = _level0[i]._x;
data_lv[i + _y] = _level0[i]._y;
}
}
data_lv.sendAndLoad(myScript.php, data_lv, POST);
/**/
This works perfectly and php receives all of the data correctly. Thanks
guys for your thoughts. I'm going to be posting an addition to the online
ActionScript documentation to hopefully help others avoid this pitfall!
