Convert Javascript Associative Object and Output it in PHP

Question

Using Javascript i create an associative object called 'basketItems'. (that resembles an associative array) I then add 'item' objects to this which hold certain item specifications as can be seen below:

// create main basketItems Object
var basketItems = new Object();

function createItem() {
    var item = new Object();
    item["number"] = number variable;     
    item["color"] = color variable;
    item["engine"] = engine variable;
    item["shape"] = shape variable;
    item["seats"] = seats variable;
    item["price"] = price variable;

    var itemUnique = unique variable;

    // Add Item into BasketItems Object
    basketItems[itemUnique] = item;
}

I then send basketItems to the server using post and on the server side my PHP code is:

<?php
$basketItems = $_POST['items'];
print $basketItems;
?>

This gives me the complete basketItems object and outputs it like below as an example:

{ 546523 = { seats = \"FOUR\"; shape = \"HATCHBACK\"; price = \"6500\"; engine = \"TWO LITRE\"; color = \"ORANGE\"; number = \"36408974\"; }; }

I need to be able to call specific parts of the basketItems object though and not just the complete contents. I have tried several attempts using the 'foreach' statement below but i always get an invalid foreach argument:

<?php
$basketItems = $_POST['items'];

foreach($basketItems as $key => $item) {
print $item['shape'];
}
?>

How could i achieve the above so that i can pick out say just the 'shape' value for all items in the basketItems Object?

If anyone could help me out on this i would really appreciate it.

Thank you in advance

---------------------Quick Update--------------------

The javascript is all being used in a mobile app being built in Titanium Appcelerator. I am not posting it with JSON, just as a standard object. The post is sent as below:

var xhr = Ti.Network.createHTTPClient();
xhr.open('POST', 'http://www.xxxxxx.com/xxxxxx.php');
xhr.onload = function () {webview.html = this.responseText;};
xhr.send({items:basketItems});

The syntax doesn't match at various places. Can you give a real example of any of the data? — mario

Hi Mario, it should be 90% correct to what i am using. I have just been asked to change some of the variable names etc by the client. Where abouts are the syntax issues as it may have just been a typo by me... — user1157360

90% isn't close enough. The structure must be exact, even if you change the identifiers. — Ignacio Vazquez-Abrams

After some consideration I believe your actual problem lies in Using Javascript i create an associative object and this is foremost a Javascript question. Show your relevant request code there. — mario

Well, your example data is all wrong. But if your input was JSON then it'd be something like:

[ { "seats": "FOUR", "shape": "HATCHBACK", "price": "6500", "engine": "TWO LITRE", "color": "ORANGE", "number": "36408974" } ]

Note that the same traversal would apply for an actual $_POST array. And it should be exactly like your example foreach.

The input you've shown is neither. It looks like some magic_quotes hampered JSON, but I'm not really sure.

Otherwise before you try anything else, use var_dump($_POST); to see the actual received structure, before you loop over it.

Is this suppose to be a JSON string? If yes, it's incorrect format.

{ 546523 = { seats = \"FOUR\"; shape = \"HATCHBACK\"; price = \"6500\"; engine = \"TWO LITRE\"; color = \"ORANGE\"; number = \"36408974\"; }; }

The value of $basketItems is a string not an array. Use json_decode http://php.net/manual/en/function.json-decode.php to decode JSON string and then you can loop over an array.

$basketItems = $_POST['items']; 

foreach($basketItems as $key => $item) {
print $item['shape'];
}
