Display steam inventory using php and api - php

Question

At the moment im getting a json reponse when i query http://api.steampowered.com/IEconItems_{appid}/GetPlayerItems/v0001/?key={apikey}&steamid={steamid}&format=json
The problem however is that i dont know what to do with this reponse without any aditional info that i cant find anywhere. A part of response im getting when looking at my own cs:go inventory:

]
}
The id's correnspond with the weapons and the rarity and quantity makes sense too. But i cant be expected to manually find every id of every weapon in every state right? Am i missing a different API that i can use to see what weapon corrensponds with what id?
ps: Sorry for bad english

Answer 1

You will call the GetSchema to determine which items these are. You'll compare DefIndex values against the ones returned by GetSchema
Your work flow will look like this:
Call GetSchema and store result of result['items'] some place to look up later
Call your current call and parse through the items. For each item, look up a result in your stored value from above
GetSchema also has rarities and other values you may need (ie. those attributes)

Answer 2

Compare your inventory defindex (not attributes) value with this schema.
http://api.steampowered.com/IEconItems_730/GetSchema/v0002/?key=xxxxx
For example,defindex = 19 is weapon_p90 on schema.

Answer 3

Try to parse JSON strings into an array. Because this response is not totaly a valid JSON string try to insert this into a new array to parse a valid JSON string.
Such as: {"main_container": [ --> YOUR POSTED CODE <-- ]}
<?php
$jsonResponse = '{"main_container": [
{
"id": 235322185,
"original_id": 190991409,
"defindex": 19,
"level": 1,
"quality": 4,
"inventory": 70,
"quantity": 1,
"rarity": 4,
"attributes": [
{
"defindex": 6,
"value": 1130627072,
"float_value": 228
},
{
"defindex": 7,
"value": 1148436480,
"float_value": 975
},
{
"defindex": 8,
"value": 1031063904,
"float_value": 0.059762358665466309
},
{
"defindex": 147,
"value": "models\/weapons\/stattrack.mdl"
},
{
"defindex": 145,
"value": "models\/weapons\/w_smg_p90_mag.mdl"
}
]
},
{
"id": 236527226,
"original_id": 236502674,
"defindex": 27,
"level": 1,
"quality": 9,
"inventory": 82,
"quantity": 1,
"rarity": 3,
"attributes": [
{
"defindex": 6,
"value": 1133608960,
"float_value": 291
},
{
"defindex": 7,
"value": 1142240880,
"float_value": 596.8505859375
},
{
"defindex": 8,
"value": 994750258,
"float_value": 0.0030927178449928761
},
{
"defindex": 80,
"value": 0,
"float_value": 0
},
{
"defindex": 81,
"value": 0,
"float_value": 0
},
{
"defindex": 147,
"value": "models\/weapons\/stattrack.mdl"
},
{
"defindex": 145,
"value": "models\/weapons\/w_shot_mag7_mag.mdl"
}
]
},
{
"id": 236529059,
"original_id": 136971214,
"defindex": 35,
"level": 1,
"quality": 4,
"inventory": 77,
"quantity": 1,
"rarity": 2,
"attributes": [
{
"defindex": 6,
"value": 1077936128,
"float_value": 3
},
{
"defindex": 7,
"value": 1141712676,
"float_value": 564.611572265625
},
{
"defindex": 8,
"value": 1031160533,
"float_value": 0.060122329741716385
},
{
"defindex": 147,
"value": "models\/weapons\/stattrack.mdl"
}
]
}
]}
';
$jsonDecodeArray = json_decode($jsonResponse, true);
foreach($jsonDecodeArray as $mainContainerItems){
// LOOP THROUGH ALL ITEM GROUP. IN THIS CASE WE HAVE 3 ITEM GROUPS IN
// $mainContainerItems ARRAY
foreach($mainContainerItems as $inventoryItem){
echo $inventoryItem['id']; // will return for example: 236529059
echo $inventoryItem['original_id']; // will return for example: 136971214
echo $inventoryItem['defindex'];
}
}
?>
In this case the resoult will be a multi dimensional array, where you can loop through with multiple foreach.
The resoult is:
$jsonDecodeArray contains the main_container array with all items, where a single item is also an array.
$inventoryItem contains a single item with it's all properties. Like shown below.
Array
(
[id] => 236529059
[original_id] => 136971214
[defindex] => 35
[level] => 1
[quality] => 4
[inventory] => 77
[quantity] => 1
[rarity] => 2
[attributes] => Array
(
[0] => Array
(
[defindex] => 6
[value] => 1077936128
[float_value] => 3
)
[1] => Array
(
[defindex] => 7
[value] => 1141712676
[float_value] => 564.61157226562
)
[2] => Array
(
[defindex] => 8
[value] => 1031160533
[float_value] => 0.060122329741716
)
[3] => Array
(
[defindex] => 147
[value] => models/weapons/stattrack.mdl
)
)
)
