Steam API Looping Help

[TheNoobCoder]

Hello. I am trying to use steam web API to access my steam inventory and report it to my website page. This is part of what I am originally returned.

        "num_backpack_slots": 150,

        },

            "inventory": 2147483650,
            "quantity": 1,
            "origin": 4
        },
        {
            "id": 1828947700,
            "original_id": 1176491289,
            "defindex": 5009,
            "level": 1,
            "quality": 6,
            "inventory": 2147483651,
            "quantity": 1,
            "origin": 4
        },
        {
            "id": 1828947742,
            "original_id": 1178541917,

            "inventory": 2147483652,
            "quantity": 1,
            "origin": 4
        },
        {
            "id": 1828947755,
            "original_id": 1178542060,
            "defindex": 5009,
            "level": 1,
            "quality": 6,
            "inventory": 2147483757,
            "quantity": 1,
            "origin": 4
        },

And so on.

What I would like to do is loop through this data for all of the defindexes of 5001 and count those up and then print them. So far this is my code. Ignore the [insert_php], that is what my WordPress plugin uses to start/end it.

$api = "http://api.steampowered.com/IEconItems_440/GetPlayerItems/v0001/?key=key+removed&steamid=id+removed&format=json";

$json = file_get_contents($api);
$schema = json_decode($json, true);
$total_metal = 0;
foreach($schema as $item)
{
    if (in_array($item->defindex, $schema));
    {
        if($item->defindex == 5001);
        {
            $total_metal+= 3;
        }
        if($item->defindex == 5002);
        {
            $total_metal+= 9;
        }
    }
}   

print $total_metal;

So far I am only returned 12 when I should be returned 63. Any help here would be great. Thanks.

MOD EDIT: [noparse][insert_php]..[/insert_php] changed to the more useful bbcode tags

..

[/noparse] - please use these in the future. Also, the 'key' in the URL is probably meant to be kept private and not given out.

Thanks. That and the steam id were meant to be taken out but I forgot to do that when copying the link.

Since I have no idea what anything actually means, I can only guess.

Considering the data excerpt you posted, it would seem that "defindex" may coexist in an item alongside "quantity". Perhaps you'd need something like

if($item->defindex == 5001);
        {
            $total_metal+= 3 * $item->quantity;
        }
        if($item->defindex == 5002);
        {
            $total_metal+= 9 * $item->quantity;
        }
}

If that doesn't help, I also noticed that some items contain "attributes" which in turn contains "defindex". Could these also be 5001 or 5002? If so, you'd need to check

foreach($item->attributes as $attr)
   if ($attr->defindex...)
