I have created a very simple test case to use the D3.JS v5 stratify method. Everything looks to be in order based on similar code but mine fails and I am not sure why. Can anyone help?

data = d3.csvParse(csvdata);
data.forEach(function(d) {
d.pk = +d.pk;
d.fk_staff = +d.fk_staff;
});
console.log(data);
let root = d3.stratify()
.id(function(d) { return d.pk; })
.parentId(function(d) { return d.fk_staff; })
(data);
console.log(root);
</script>
</body>
</html>
The issue is happening here:
data.forEach(function(d) {
d.pk = +d.pk;
d.fk_staff = +d.fk_staff;
});
Some of the data has an empty string as d.fk_staff. When the empty string is coerced to a number it becomes 0, and there is no data with d.pk equals to 0, hence the error.
A simple fix is to not coerce the empty string:
data.forEach(function(d) {
d.pk = +d.pk;
d.fk_staff = d.fk_staff === '' ? '' : +d.fk_staff;
});

I am trying to upload single image using codeigniter. But getting error
"Undefined property: Main::$upload
Filename: controllers/Main.php
Line Number: 14"
This is my controller file "controller/Main.php"
<?php
class Main extends CI_Controller
{
public function index(){
$this->load->view('main_view', array('error' => ''));
}
public function upload(){
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|png|gif';
$this->load->initialize('upload', $config);
if(!$this->upload->do_upload()){
$error = array('error' => $this->upload->display_errors());
$this->load->view('main_view', $error);
}
else {
$file_data = $this->upload->data();
$data['img'] = base_url().'/images/'.$file_data['file_name'];
$this->load->view('success_msg', $data);
}
}
}
?>
and this is my view file "views/main_view.php"
<!DOCTYPE html>
<html>
<head>
<title>Image</title>
</head>
<body>
<?php echo $error; ?>
<?php echo form_open_multipart('main/upload');?>
<input type="file" name="userfile" />
<input type="submit" name="Submit" value="upload image"/>
</form>
</body>
</html>
when image upload is successful I'm trying to show the image by this "view/success_msg.php"
<!DOCTYPE html>
<html>
<head>
<title>Image</title>
</head>
<body>
<h1>File has been uploaded.</h1>
<img src="<?php $img?>" width="300" height="300">
</body>
</html>
my image folder name is "images" and it is in the root directory. Please help my why I am having this error ?
Maybe the upload library isn't loaded. Change the first few lines ofpublic function upload() to the following
public function upload(){
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|png|gif';
$this->load->library('upload', $config);
By sending $config to load->library you do not need to use initialize().
Controller
public function upload(){
$cc = $_FILES['userfile']['name'];
$extension = pathinfo($cc, PATHINFO_EXTENSION);
$newfile = preg_replace('/[^A-Za-z0-9]/', "", $_FILES["userfile"]['name']);
$config['file_name'] = time() . $newfile;
$ss = ".";
$picture1 = time() . $newfile . $ss . $extension;
$config['upload_path'] = "./images/";
$config['allowed_types'] = 'jpg|jpeg|png|gif|pdf';
$this->load->library('upload', $config);
if (!$this->upload->do_upload('userfile')) {
echo $this->upload->display_errors();
} else {
$this->load->view('success_msg', $picture1 );
}
}

</head>
<body>
<button onclick="getImage()">get img</button>
<div id="imager"></div>

And this is my prova.php test page:
$max = 0;
$imgToLoad = null;
// Open image dir
if ($handle = opendir('img')) {
while (false !== ($entry = readdir($handle))) {
if($entry == '.' || $entry == '..' ) continue;
if($_POST['index'] == $max)
// Save next image to show
$imgToLoad =$entry;
// Image counter
$max++;
}
closedir($handle);
}
$array = array(
"max" => $max,
"imageToLoad" => "http://192.168.1.96/prove/cache/img/".$imgToLoad
);
// Return next image and max number of image the we can show
echo json_encode($array);
The problem is that every time that i call "getImage()" the memory browser incrase ( IE and Firefox tested).
My 'img' folder contains a lot of very huge images, about 4600x3000px (400kb), and after a little time the memory brower is about 1 gb and so on.
Thanks for help
I am developing an app with 2 files:
index.php (application container)
process.php (called in ajax)
index.php
<?php
include 'config.php';
include 'lib/functions.php';
require_once 'lib/sdk/facebook.php';
$facebook = new Facebook(array(
'appId' => APP_ID,

));
$userID = $facebook->getUser();
if (!$userID)
{
$scope = 'read_stream, publish_stream, user_likes, user_photos, user_status, friends_hometown, friends_location, friends_likes, photo_upload';
$params = array(
'scope' => $scope,
'redirect_uri' => "https://apps.facebook.com/".APP_NAME."/"
);
$loginUrl = $facebook->getLoginUrl($params);
}
else
{
$access_token = $facebook->getAccessToken();

}
In 95% of cases application works fine but sometimes $facebook->api('/me'); trows the exception "An active access token must be used to query information about the current user." and the $userID is equal to 0.
In order to have the same session id in all files I have to start manually session with the session_id passed by index.php in POST. This is because some browser (IE, safari) don't pass cookies of third party pages in iframe. (http://stackoverflow.com/questions/9930671/safari-3rd-party-cookie-iframe-trick-no-longer-working)
Any suggestions?
Thank you
check whether the session value is passing properly or not?
