I would know, why JSON encoded data (from MongoDB via PHP) presented as:
{
"53a6e02221360e263e000000": {
"_id": {
"$id": "53a6e02221360e263e000000"
},
"title": "1"
},
"53a6e02221360e263e000001": {
"_id": {
"$id": "53a6e02221360e263e000001"
},
"title": "2"
}
}
is bad, but:
[
{
"id": "53a6e02221360e263e000000",
"title": "1"
},
{
"id": "53a6e02221360e263e000001",
"title": "2"
}
]
is good?
Is any idea? Both valid JSON.
PHP code example:
// MongoDB init before it
$cursor = $mongo->db->collection->find();
// For not large data
$result = iterator_to_array( $cursor );
$json = json_encode($result);
var_dump($json);

Ive got the following JSON:
{
"servers": [
{
"id": "f34c0185-4c9e-40fd-82f6-1d6e9a5d499e",
"name": "vm01"
},
{
"id": "d671ac7d-3b5a-4777-8510-6e8e58295061",
"name": "vm02"
},
{
"id": "h59j23cc-9ve2-4508-1277-85y1lo27562m",
"name": "vm03"
}
]
}
I also have another JSON that gives me the ID I want to search for.
For example: "d671ac7d-3b5a-4777-8510-6e8e58295061".
I want to search for the JSON Object, that contains that ID and get the value of the name key. I tried with loops and if, else's but I didn't manage to get it working.
Thanks for your help!
decode the json as array object then loop through with the ID that u want to search
<?php
$json = '{
"servers": [
{
"id": "f34c0185-4c9e-40fd-82f6-1d6e9a5d499e",
"name": "vm01"
},
{
"id": "d671ac7d-3b5a-4777-8510-6e8e58295061",
"name": "vm02"
},
{
"id": "h59j23cc-9ve2-4508-1277-85y1lo27562m",
"name": "vm03"
}
]
}';
$j = json_decode($json, true);
foreach($j['servers'] as $arr)
{
if( $arr['id'] == 'd671ac7d-3b5a-4777-8510-6e8e58295061' ) echo $arr['name'];
}

How to get absentees using angular in an array.
Angular part i tried didnt work
this.http.post("http://localhost/android/Api.php?apicall=getattendance", JSON.stringify(this.postData),options)
.subscribe( (data) => {
this.setUsersArray(data);
console.log(data + "URL DATA"+JSON.stringify(this.postData));
}
);
=====================================================================
setUsersArray(data){
if (data instanceof Array) {
{
this.date_present = data.map(function (ele) {
if(ele.status==='present')
{
return ele.date;
}
});
this.date_absent = data.map(function (ele) {
if(ele.status==='absent')
return ele.date;
});
}
}
I am getting date_absent and date_present as null.Why am i getting this as null.Please help me. I am new to angular.
try for loop in typescript
setUsersArray(data:any){
for(let item of data){
console.log(item);
if(item.status==='present') {
this.present.push(item.date);
}
if(item.status==='absent') {
this.absent.push(item.date);
}
}
Trying to this url
$characters = json_decode($data, true); // decode the JSON feed and make an associative array

I have never used JSON before so apologies if this is a simple request.
I have a webhook setup that sends me a JSON Post (Example Below) - I want to extract the two answers from this "text":"250252" & {"label":"CE"}
{
"event_id": "1",
"event_type": "form_response",
"form_response": {
"form_id": "VpWTMQ",
"token": "1",

"ref": "9ac66945-899b-448d-859f-70562310ee5d",
"allow_multiple_selections": false,
"allow_other_choice": false
},
{

"title": "Please select the skill required",

}
},
{
"type": "choice",
"choice": {
"label": "CE"
},
"field": {
"id": "JQD4ksDpjlln",
"type": "multiple_choice"
}
}
]
}
}
I have this currently in my PHP file:
$data = json_decode(file_get_contents('php://input'));
$ID = $data->{"text"};
$Skill = $data->{"label"};
This does not work and all I get is null - Any help would really be appreciated, Thank You.
You need to look at the JSON object you're receiving to know the structure of the object you're receiving after using json_decode, what you're trying to get is in $data->form_response->answers, So you can have a variable for easier access:
$answers = $data->form_response->answers;
remember $answers is an array
So to achieve what you're trying to get, you can do:
$data = json_decode(file_get_contents('php://input'));
$answers = $data->form_response->answers;
$ID = $answers[0]->text;
$Skill = $answers[1]->choice->label;
I a trying to decode a json callback.
The json code is posted to callback.php - Here is an example of the json:
{
"order": {
"id": "5RTQNACF",
"created_at": "2012-12-09T21:23:41-08:00",
"status": "completed",
"total_btc": {
"cents": 100000000,
"currency_iso": "BTC"
},
"total_native": {
"cents": 1253,
"currency_iso": "USD"
},
"custom": "order1234",
"receive_address": "1NhwPYPgoPwr5hynRAsto5ZgEcw1LzM3My",
"button": {
"type": "buy_now",
"name": "Alpaca Socks",
"description": "The ultimate in lightweight footwear",
"id": "5d37a3b61914d6d0ad15b5135d80c19f"
},
"transaction": {
"id": "514f18b7a5ea3d630a00000f",
"hash": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
"confirmations": 0
},
"customer": {
"email": "coinbase#example.com",
"shipping_address": [
"John Smith",
"123 Main St.",
"Springfield, OR 97477",
"United States"
]
}
}
}
I can echo the json and get the following response:
{"order""id":null,"created_at":null,"status":"completed","total_btc":{"cents":100000000,"currency_iso":"BTC"},"total_native":{"cents":83433,"currency_iso":"USD"},"custom":"123456789","receive_address":"1A2qsxGHo9KjtWBTnAopTwUiBQf2w6yRNr","button":{"type":"buy_now","name":"Test Item","description":null,"id":null},"transaction":{"id":"52d064b59eeb59985e00002c","hash":"4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b","confirmations":0}}}
However if I try to decode the json using the following:
$array = json_decode($jsonString, true);
echo $array;
I get the following response: "200 Array"
I want to be able turn each json parameter in to a php variable.
You can access the variables within $array, for example by doing:
echo $array['custom']; // prints out "order1234"
You don't want to extract the variables directly into the local lexical scope of your program as that would create security concerns. Just use the data as indicated in the snippet above.
Need some help with the sample code provided the facebook. I can't get it to return a series of IDs that I need to run a sql query against.
$friends = '{
"data": [
{
"name": "Paul",
"id": "12000"
},
{
"name": "Bonnie",
"id": "120310"
},
{
"name": "Melissa",
"id": "120944"
},
{
"name": "Simon",
"id": "125930"
},
{
"name": "Anthony",
"id": "120605"
},
{
"name": "David",
"id": "120733"
}
]
}';
$obj = json_decode($friends);
print $obj->{'data'}[0]->{'name'};
I can return the "Paul"
what I want is to return all the id's using implode(array_keys($obj),",")
I am only getting data to return.
What I'd like to do is retrieve all the IDs separated by a comma.
Thanks!
Try implode-ing on the data key with array_map:
function get_id($o) {
return $o->id;
}
implode(array_map('get_id', $obj->data),",")
