Issue with JSON and jQuery Iteration - php

Question

I'm pretty sure it's an obvious error somewhere on this - but let me explain what I'm donig :
I'm calling a PHP file via jQuery as follows :
$.getJSON("/phpincs/getbucket.php?awskey="+awskey+"&awssecret="+awssecret+"&bucket="+bucket,
function(json){
$.each(json,function(i,item){
$(new Option(item.name,item.name)).appendTo('#bucket_contents_0');
});
}
and the JSON file it returns is as follows :
Array
(
[bt_shop.png] => Array
(
[name] => bt_shop.png
[time] => 1260393948
[size] => 156985
[hash] => 8a4eba621d5e08b84c962a0ad21ec2ae
)
[me_profile.jpg] => Array
(
[name] => me_profile.jpg
[time] => 1260393952
[size] => 2714
[hash] => 4f5d185b0c671e6165902762681f098b
)
[thumbnail.aspx.jpeg] => Array
(
[name] => thumbnail.aspx.jpeg
[time] => 1260393951
[size] => 5268
[hash] => 6939efa58ff7ffcac17218ffdd0d5d8c
)
)
true
for some reason it doesn't seem to fire the function(json){} - I've stuck an alert(''); in and it doesn't do anything.
Can someone quickly explain to me what seems to be going wrong there?
Cheers,
Carl

Answer 1

It is more than likely not calling the callback function because it doesn't look like what you are returning is json. If you have an $variable defined that contains your array...call
echo json_encode($jsondata); exit;
At the end of your script.

Answer 2

I've changed the names of the inner arrays as your previous labels are going to cause problems with the dot. You will get an error like:
myArray.bt_shop is undefined
when you try to call
alert(myArray.bt_shop.png.name);
the only way it could be called is with
alert(myArray["bt_shop.png"].name);
So having changed your code a bit, this is the JSON version of your arrays...
{
"one":
{
"name": "bt_shop.png",
"time": "1260393948",
"size": "156985",
"hash": "8a4eba621d5e08b84c962a0ad21ec2ae"
},
"two":
{
"name": "me_profile.jpg",
"time": "1260393952",
"size": "2714",
"hash": "4f5d185b0c671e6165902762681f098b"
},
"three":
{
"name": "thumbnail.aspx.jpeg",
"time": "1260393951",
"size": "5268",
"hash": "6939efa58ff7ffcac17218ffdd0d5d8c"
}
}
Then you reference your fields like this when you have the object:
myArray["two"]["name"]
myArray["two"].name
myArray.two.name

Answer 3

Your returned file isn't JSON. Unless you're using PHP syntax to describe your JSON object for us, you need to encode it into JSON format using json_encode.

Answer 4

What you call the JSON file isn't JSON. Or maybe do you use some PHP library that converts that strange format into JSON ?
