Question

i’ve tried a few different json methods (stringify, toJSON, and probably some totally irrelevant others out of desperation) but can’t seem to figure out how to stringify this so i can pass it to a php script. i am able to create a two dimensional array that which could be represented something like this:

array(
    'image'=>array(
        0=>'hello.jpeg', 
        1=>'goodbye.jpeg', 
        2=>'etc.jpeg'),
    'resume'=>array(
        0=>'resume.doc'),
    'reel'=>array(
        0=>'reel.mov')
    )

the array looks okay when i print it to console using this dump function. i tried figuring out how to get this to work with objects because i thought i read something that said objects were already JSON friendly, but since i’m not super familiar with javascript i was pretty much floundering about.

edit: some more details… the declaration of my array (when i had it working) was something like this, although i may have messed up:

var fileArray = [];
fileArray['image'] = [];
fileArray['resume'] = [];
fileArray['reel'] = [];

var type;
var name;

var divs = $("#upload-container").children('div');

$.each(divs, function() {
    type = $(this).attr('id');
    name = $(this).html();

    fileArray[type].push(name);
});

The object for that array structure might look like this in JavaScript:

var objects = 
[
    {
        'image': [
            { '0': 'hello.jpeg' },
            { '1': 'goodbye.jpeg' },
            { '2': 'etc.jpeg' }
        ]
    },
    {
        'resume': [
            { '0': 'resume.doc' }
        ]
    },
    {
        'reel': [
            { '0': 'reel.mov' }
        ]
    }
]

So now you’ve got an array of three objects, each of which contains a property (image, resume, reel) that is another array of objects with basically key:value pairs ('0':'hello.jpeg'). Maybe you could simplify it by not bothering to use the indexes:

var objects = 
[
    {
        'image': [ 'hello.jpeg', 'goodbye.jpeg', 'etc.jpeg' ]
    },
    {
        'resume': [ 'resume.doc' ],
    },
    {
        'reel': [ 'reel.mov' ]
    }
]

Then you can use JSON.stringify(objects) to pass to your PHP action.
