I am trying to convert an array obtained by the code below using non-deprecated techniques with php pdo:
$stm = $conn->prepare("SELECT * FROM mysqltable");
$stm->execute();
$results = $stm->fetchAll(PDO::FETCH_ASSOC);
print_r($results);
to the following format required for fusioncharts to be used
[
{
label: "CJ Anderson",
value: "25"
},
{
label: "Imran Tahir",
value: "25"
},
...
...
]
The original array is as follows:
Array (
[0] => Array (
[Id] => 6
[Number] => 1234567890
[Visits] => 1
[Name] => John
)
[1] => Array (
[Id] => 7
[Number] => 1236549871
[Visits] => 9
[Name] => Jerry
)
[2] => Array (
[Id] => 8
[Number] => 2147483647
[Visits] => 3
[Name] => Jane
)
)
Any help would be appreciated, thanks.
EDIT:
As I commented below. I have a full php file that works if you put data in manually. I can't get it to work though when I put the $jsonEncodedData in though. Thoughts?

==============Edit 12/28/15==========
Tried the following code with no results, Question I have is shouldn't we end in "}" as they require that:
$columnChart = new FusionCharts(
"column2d",
"ex1" ,
"600",
"400",
"chart-1",
"json",
'{
"chart":
{
"caption":"Harry\'s SuperMart",
"subCaption":"Top 5 stores in last month by revenue",
"numberPrefix":"$",
"theme":"ocean"
},
"data": ' . $jsonEncodedData);
//}';
// Render the chart
print_r($columnChart);
$columnChart->render();
?>
<div id="chart-1"><!-- Fusion Charts will render here--></div>
</body>
</html>
I wanted to post the array differences as well between the "manual" method and the "fetch method (above in this edit).
With fetch:
FusionCharts Object ( [constructorOptions:FusionCharts:private] => Array ( >[type] => column2d [id] => ex1 [width] => 600 [height] => 400 [renderAt] => >chart-1 [dataFormat] => json [dataSource] => { "chart": { >"caption":"Harry's SuperMart", "subCaption":"Top 5 stores in last month by >revenue", "numberPrefix":"$", "theme":"ocean" }, "data": >[{"label":"John","value":"125"},{"label":"Jerry","value":"125"},{"label":"Jane","value":"125"}] ) [constructorTemplate:FusionCharts:private] => >[renderTemplate:FusionCharts:private] => )
With Manual Method (that works):
FusionCharts Object ( [constructorOptions:FusionCharts:private] => Array ( >[type] => column2d [id] => ex1 [width] => 600 [height] => 400 [renderAt] => >chart-1 [dataFormat] => json [dataSource] => { "chart": { >"caption":"Harry's SuperMart", "subCaption":"Top 5 stores in last month by >revenue", "numberPrefix":"$", "theme":"ocean" }, "data": [ { >"label":"Bakersfield Central", "value":"880000" }, { "label":"Garden Groove >harbour", "value":"730000" }, { "label":"Los Angeles Topanga", >"value":"590000" }, { "label":"Compton-Rancho Dom", "value":"520000" }, { >"label":"Daly City Serramonte", "value":"330000" } ] } ) >[constructorTemplate:FusionCharts:private] => >[renderTemplate:FusionCharts:private] => )
I see two differences offhand, the manual inserts spaces around "data" and the ending } parameter.
There is an automatic (and much much easier) way of doing this:
$stm = $conn->prepare('SELECT Name AS label, Visits AS value FROM mysqltable;');
$stm->execute();
$results = $stm->fetchAll(PDO::FETCH_ASSOC);
$jsonEncodedData = json_encode($results);
echo $jsonEncodedData;
Output (locally tested):
[{"label":"Foo","value":"5"},{"label":"Bar","value":"15"}]
That way you can just use it like this:
$columnChart = new FusionCharts('...
...
"data": ' . $jsonEncodedData . '}');
Note the . '}' in the end.
Before Edit:
You could do something like this:
// This part is just for running purposes
$foo = array (
0 => Array (
'Id' => 6,
'Number' => 1234567890,
'Visits' => 1,
'Name' => 'John'
),
1 => array (
'Id' => 7,
'Number' => 1236549871,
'Visits' => 9,
'Name' => 'Jerry'
),
2 => array (
'Id' => 8,
'Number' => 2147483647,
'Visits' => "3", // Example to output quoted
'Name' => 'Jane'
)
);
$bar = array();
foreach($foo as $k => $v){
$bar[] = array('label' => $foo[$k]['Name'], 'value' => $foo[$k]['Visits']);
}
echo json_encode($bar);
Output:
[{"label":"John","value":1},{"label":"Jerry","value":9},{"label":"Jane","value":"3"}]
Compare with yours (from question) in one line:
[{label: "CJ Anderson",value: "25"},{label: "Imran Tahir",value: "25"},...]
Note: I assumed that value is represented by Visit and label by Name.
Read more about json_encode.
As a summary this is the piece that solved the issue including FirstOne's foreach statement:
$stm = $conn->prepare("SELECT Name, Visits FROM mysqltable"); //WHERE Area :SelArea");
$stm->execute();
$results = $stm->fetchAll(PDO::FETCH_ASSOC);
include("fusioncharts.php");
$jsnarray = array();
foreach($results as $k => $v){
$jsnarray[] = array('label' => $results[$k]['Name'], 'value' => $results[$k]['Visits']);
};
$jsonEncodedData=json_encode($jsnarray);
//print_r($jsonEncodedData);
new FusionCharts("type of chart",
"unique chart id",
"width of chart",
"height of chart",
"div id to render the chart",
"type of data",
"actual data");
$columnChart = new FusionCharts(
"column2d",
"ex1" ,
"600",
"400",
"chart-1",
"json",
'{
"chart":
{
"caption":"Harry\'s SuperMart",
"subCaption":"Top 5 stores in last month by revenue",
"numberPrefix":"$",
"theme":"ocean"
},

// Render the chart
print_r($columnChart);
$columnChart->render();
?>

Thanks for everyone's help in solving the issue.

I am trying to build a multi-dimensional array from a query return and ran into a problem. Here is a sanitized snippet similar to what I am trying to do. My problem is building the sub array. Any suggestions to get my desired output? I used JSON so it would be more obvious. I can parse an array or JSON.
<?php
// this is my query
global $wpdb;
$locationData = $wpdb->get_results("SELECT
locations.locationID,
locations.location_name,
locations.city,
locations.state,
locations.products,
locations.type,
locations.sku
");
// which returns something like
// [locationID] [location_name] [city] [state] [products] [type] [sku]
// 001 Tulsa Outlet Tulsa OK cakes chocolate 3763
// 001 Tulsa Outlet Tulsa OK cakes lemon 3765
// 001 Tulsa Outlet Tulsa OK sodas coke 4983
// 001 Tulsa Outlet Tulsa OK sodas sprite 4950
// and so on..
// I build an array to be consumed by another function that I created in my plugin:
foreach( $locationData as $key => $location ) {
$output[$row['locationID']] = array(
'locationID' => $row['locationID'],
'location_name' => $row['location_name'],
'products' => array(
// this is where my previous attempts broke down
)
);
$output[$key]['city'] = $location->city;
$output[$key]['state'] = $location->state;
}
// and the $output I need would look like this:
{
"locations" : [
{
"locationID" : "001",
"location_name" : "Tulsa Outlet",
"products" : {
"cakes" : {
"chocolate" : "3763",
"lemon" : "3765"
},
"sodas" : {
"coke" : "4983",
"sprite" : "4950"
}
},
"city" : "Tulsa",
"state" : "ok"
}
]
}
?>
These should help:
$output = [];
foreach ($locationData as $location) {
$locId = $location->locationID;
if (empty($output[$locId])) {
$output[$locId] = [
'locationID' => $location->locationID,
'location_name' => $location->location_name,
'city' => $location->city,
'state' => $location->state,
'products' => [],
];
}
$productType = $location->products;
if (empty($output[$locId]['products'][$productType])) {
$output[$locId]['products'][$productType] = [];
}
$output[$locId]['products'][$productType][$location->type] = $location->sku;
}
Not really sure what you use - $row or $location, so changed everything to $location.
To reindex $output to 0-index array, use array_values.
I need to make a join between two collections at the same time i need to execute filter for the first collection , exemple :
... // code inside my classe
$this->MDBManager = new MongoDB\Driver\Manager("mongodb:// xxxxx: xxxxx #" . $this->host);
$filter = array ("date", array('$gte' =>str_replace("-","/", "2019-10-5") , '$lte' => str_replace("-","/", 2019-10-15)))
$this->MDBQuery = new MongoDB\Driver\Query($filters, $options);
$this->results = $this->MDBManager->executeQuery("mydb.colllection1", $this->MDBQuery);
so this is my first collection and i need to join the soconde collection id to matche the same value of productEnsembleId attribute in collection 1.
The join request need to be in only one request .
Thnak you so much for your help .
For more details :
exemple collection 1 :
{

So assuming you want the join results for one document in the first collection, here is a mongo shell query.

I have a JSON array like this:
{

customer_dashboard_email:"******",

used:"0.00",
name:"Trial",
price:0,
bandwidth:1,
start_date:"2018-07-20",
end_date:"2018-07-27",
package_is_active:1
},
{
customer_id:16648,
customer_name:"asd#asd.asd",
customer_login_name:"******",
customer_login_pwd:"********",
customer_active:1,
customer_register_date:"2018-08-08 17:24:16",
customer_dashboard_email:"******#*******.com",
customer_dashboard_pwd:"******",
used:"0.00",

},

customer_name:"MarioRossiTEST",

}
}
Now in PHP i would like to provide the "customer_name" and retreive the "customer_id" of the same customer.
For example i provide "test#test.test" and i would like to get "16096".
Any way i could do this?
EDIT: After decoding the JSON array to PHP:
If you are doing this very often, I would suggest for looping through the array and creating a dictionary with the "customer_name" value as the key and the "customer_id", "customer_login_name", etc. in a dictionary that's the value to the "customer_name" key.
$customers_dic = {
"test#test.test"=> {
customer_id => 16096,
customer_login_name => "******",
customer_login_pwd =>"*****",
customer_active => 0,
customer_register_date => "2018-07-20 10:48:22",
customer_dashboard_email => "******",
customer_dashboard_pwd => "******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-07-20",
end_date => "2018-07-27",
package_is_active => 1
},
"asd#asd.asd" => {
customer_id => 16648,
customer_login_name => "******",
customer_login_pwd => "********",
customer_active => 1,
customer_register_date => "2018-08-08 17:24:16",
customer_dashboard_email => "******#*******.com",
customer_dashboard_pwd => "******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-08-08",
end_date => "2018-08-15",
package_is_active => 1
},
"mario#test.test" => {
customer_id => 15271,
customer_name => "MarioRossiTEST",
customer_login_pwd => "*****",
customer_active => 0,
customer_register_date => "2018-06-22 11:36:42",
customer_dashboard_email => "*****#******.com",
customer_dashboard_pwd => "*******",
used => "0.00",
name => "Trial",
price => 0,
bandwidth => 1,
start_date => "2018-06-22",
end_date => "2018-06-30",
package_is_active => 0
},
}
This way you can quickly access any "customer_id" by going $customers_dic["some#customer.name"]["customer_id"].
If you are just doing this a small number of times, you can just for loop through the customers array, keeping track of the index and checking if you have arrived on the desired customer's name.
$desired_customer_id;
for ($i = 0; $i < count($customers); $i++) {
if ($customers[$i]["customer_name"] === $desired_customer_name) {
$desired_customer_id = $customers[$i]["customer_id"];
}
}
You could also do this with a foreach instead; choice is up to you. :)
http://php.net/manual/en/function.json-decode.php
$arr = json_decode($json, true);
then you need to find your customer
array_filter($arr['result']['customers'], function ($customer) {
return ($customer['customer_name'] === 'test#test.test')
});

Here i have one array, in this array i have one more array called studentabsentId,
public function admin_getabsentlist()
{
$data = array(
"schoolId" => $_POST['schoolName'],
"classId" => $_POST['className'],
"sectionId" => $_POST['sectionName'],
"absentDate" => date("Y-m-d", strtotime($_POST['absentDate']))
);
$absentresponse= $this->Admin_attendance_model->admin_options_listdisplay($data);
$optionsList = array();
foreach($absentresponse as $hmres)
{
$hmparent['studentabsentId']=json_decode($hmres['studentAbsentId']);
$hmparent['studentAbsentDate']=$hmres['studentAbsentDate'];
array_push($optionsList,$hmparent);
}
//echo $json = json_encode($optionsList);
$return = array("status" => 1, "data" => $optionsList);
echo json_encode($return);
}
echo json_encode($return);
{
"status": 1,
"data": [
{
"studentabsentId": [
"1"
],
"studentAbsentDate": "2017-04-12"
}
]
}
upto now its working fine,now what i want means,studentabsentId 1 means what is his name,suppose studentabsentId 2 means what is name, for that purpose i written the function called getStudentnameById in helper/custom_helper.php.
So in my for each loop i added one more line like this
$hmparent['studentabsentName']=json_decode(getStudentnameById($hmres['studentAbsentId']));
But now i am getting the error of Undefined offset: 0,how can solve this error and , how to display the name
custom_helper.php
if ( ! function_exists('getStudentnameById')){
function getStudentnameById($id){
$ci =& get_instance();
$ci->load->database();
$ci->db->select('firstName');
$ci->db->where('student_id', $id);
$q = $ci->db->get('new_student')->result();
return $q[0]->firstName; // particulart filed
}
}
My updated code
print_r($absentresponse);
Array
(
[0] => Array
(
[absendId] => 2
[studentAbsentId] => ["1"]
[studentAbsentDate] => 2017-04-12
[schoolId] => 2
[classId] => 1
[sectionId] => 1
[reg_date] => 2017-04-13 01:01:14
[created_by] => kanniyappan#g2evolution.co.in
[status] => 0
)
)
Expected Results
{
"status": 1,
"data": [
{
"studentabsentId":"1"
"studentabsentName":"Kani"
"studentAbsentDate": "2017-04-12"
}
]
}
Your getStudentnameById returns a string supposedly, so why are you doing a json_decode on top of that. $hmparent['studentabsentName']=json_decode(getStudentnameById($hmres['studentAbsentId']));
Also check the return by that function. You should be able to debug this kind of code if you turned on your error_reporting which tells you the line at which error occurred, then var_dump all the variables that's relevant to it.
I use this method to generate a pass: public function setJSON($JSON) {
if(json_decode($JSON) !== false) {
$this->JSON = $JSON;
return true;
}
$this->sError = 'This is not a JSON string.';
return false;
}
I call this method to generate pass by: $pass->setJSON('{
"passTypeIdentifier": "'.$passTypeID.'",
"formatVersion": 1,
..............
"barcode": {
"altText" : "'.$alt.'",
"format" : "PKBarcodeFormatPDF417",
"message": "Member-Card",
"messageEncoding": "iso-8859-1",
"changeMessage" : "This pass now has altText %# !"
},
"locations" : [
{
"longitude" : 104.89529371261597,
"latitude" : 11.576150037278605,
"relevantText": "CamMob (dis. 1%)"
},
.....................
]
}');
But now I don't write those locations statically and I get those data from database by : $query5 = mysql_query("select * from company");
while ($row5 = mysql_fetch_array($query5)){
$companyName = $row5['relevantTextName'];
$discount = $row5['relevantTextDiscount'];
$long = $row5['longitute'];
$lat = $row5['latitute'];
$link = $row5['link'];
$location['locations'][] = array("longitute" => $long, "latitute" => $lat, "relevantText" => $companyName." (" . $discount. "%)" );
}
$jsonString = json_encode($location) ;
error_log("Locations: ".$jsonString,0);
$pass->setJSON($jsonString);
$pass->setJSON('{
"passTypeIdentifier": "'.$passTypeID.'",
"barcode": {
"altText" : "'.$alt.'",
"format" : "PKBarcodeFormatPDF417",
"message": "Member-Card",
"messageEncoding": "iso-8859-1",
"changeMessage" : "This pass now has altText %# !"
}
}');</pre>
There is no error when I test for updating pass, but I cannot see the pass on lock screen like before. Thus it means that I not yet include those locations to the pass. What should I change ? Is it the problem of method setJSON ? If I do like this, how can I combine these 2 jsons to become together ?
Rather than constructing the JSON directly, construct an array first, then transform it into JSON.
$pass_data = array("passTypeIdentifier" => $passTypeID,
"formatVersion" => 1,
"barcode" => array (
"altText" => $alt,
"format" => "PKBarcodeFormatPDF417",
"message" => "Member-Card",
"messageEncoding" => "utf-8", // use UTF8 in case you want to encode Khmer or other non ASCII
"changeMessage" => "This pass now has altText %# !"
),
"locations" => $locationsArray,
"organizationName" => "Digi club card",
"description" => "Membership card",
"logoText" => "Digiclub",
"foregroundColor" => "rgb(0,0,0)",
"backgroundColor" => "rgb(211,211,211)",
"generic" => array (
"headerFields" => array(
array ( "key" => "Status",
"label" => " ",
"value" => "Membership card"
),
),
"primaryFields" => array(
array ( "key" => "Name",
"value" => $memberName,
),
),
"secondaryFields" => array(
// Secondary Field data
),
"auxiliaryFields" => array(
// Auxiliary Field data
),
"backFields" => array(
// Backfiels Field data
),
)
);
Then transform the array into JSON:
$pass->setJSON(json_encode($pass_data));
