Generate tree directory for Fancytree

[ScottMeyer]

Hello,

I am using Fancytree, I want to generate a file / folder tree but excluding all folders that are not from the current user.

Example:
BOLD= FOLDER

I want to create a tree structure with the user "Peter"

[Tree]
├─PERSONNAL (take)
│ ├─PAN (not take)
│ │   └─GAMES (not take)
│ │      └─list (not take)
│ └─PETER (take)
│      └─GUITAR (take)
│           └─tabs (take)
└─TEAM (take)
     ├─CONTACT (take)
     │      └─phone (take)
     └─INFORMATION (take)
             └─technique (take)

I have several problems:
1) I don't understand the "listFolders" function, I can't give it a parameter (like $ name_user) otherwise it doesn't work.
2) the lines >> print_r ('TAKE THIS'. $ Dir); << show what I want to take, but it is "foreach" which does not work
3) my code is duplicated because I can't create a function inside a function ...

Here is my code:

<?php
$name_user = 'Peter'; // actualy not user :-( 
print_r(listFolders());

function listFolders($dir = __DIR__ . '/datausers') {
    $dh = scandir($dir);
    $name_user = "Peter";
    $return = [];

    if (strpos($dir, "/datausers/PERSONNAL") !== false){ // PERSONNAL found !
        if ($dir === __DIR__ . '/datausers/PERSONNAL') {  
            print_r($dir);
            echo '</br>';

            foreach ($dh as $item) {
                if ($item != '.' && $item != '..') {
                    if (is_dir($dir . '/' . $item)) { // it's a folder
                        $return[] = array(
                            'title' => $item,
                            'folder' => true,
                            'expanded'=> true,
                            'children' => listFolders($dir . '/' . $item, $key)
                        );
                    } else { // it's a file
                        $return[] = [
                            'title' => $item,
                        ];
                    }
                }
            }
        }
        if (strpos($dir, "/datausers/PERSONNAL/" . $name_user) !== false){ // Peter found
            print_r($dir);
            echo '</br>';

            foreach ($dh as $item) {
                if ($item != '.' && $item != '..') {
                    if (is_dir($dir . '/' . $item)) { // it's a folder
                        $return[] = array(
                            'title' => $item,
                            'folder' => true,
                            'expanded'=> true,
                            'children' => listFolders($dir . '/' . $item, $key)
                        );
                    } else { // it's a file
                        $return[] = [
                            'title' => $item,
                        ];
                    }
                }
            }
        }
    } 
    else {
        print_r($dir);
        echo '</br>';

        foreach ($dh as $item) {
            if ($item != '.' && $item != '..') {
                if (is_dir($dir . '/' . $item)) { // it's a folder
                    $return[] = array(
                        'title' => $item,
                        'folder' => true,
                        'expanded'=> true,
                        'children' => listFolders($dir . '/' . $item, $key)
                    );
                } else { // it's a file
                    $return[] = [
                        'title' => $item,
                    ];
                }
            }
        }
    }
    return $return;
}
?>

Please help me I'm desperate ...

1. What's the original code before you started making changes?
2. How do you know what folders are "from" a user?

[ScottMeyer]

hi, thank you for your answer.

I am using a POST AJAX request to find out the name of the user. This part works, here the ajax request is simulate with "$name_user".

I would have liked to do:

$user_name = "Peter";
echo json_encode (listFolders ($user_name));
function listFolders ($path_user, $dir = __DIR__. '/datausers') {

i compare, if $_SESSION['username'] = $name_user for sécurity
The goal is to use as return with "echo json_encode (listFolders ());" to put in Fancytree.

Okay. What's the original code before you started making changes, and how do you know what folders are "from" a user?

[ScottMeyer]

I give you my original code. it is currently returning all folders and files.

<?php
if(session_status() != 2) {	session_start(); } else { header('Location: deco.php'); } // (2 = session active) if don't active session
if (!isset($_SESSION['username']) || empty($_SESSION['username'])) {header('Location: deco.php');} // redirection si pas de session ouverte
if (time() > $_SESSION['expire']) {
    session_destroy();
    header('Location: deco.php');
}
$e1 = isset($_POST['e1']) ? $_POST['e1'] : null;
$e2 = isset($_POST['e2']) ? $_POST['e2'] : null;
if (empty($e1) || empty($e2)) {
    $return_data['key1'] = 'error';
    echo json_encode($return_data);
    return;
}

if ($e1 == 'read'){
    $e2 = str_replace('<','',$e2); // just for prevent html injection
    $e2 = str_replace('?','',$e2); // just for prevent php injection
    $return_data['key1'] = 'read';
    $return_data['key2'] = $e2;
    echo json_encode($return_data);
    return;

    $e2 = str_replace('}','',$e2); 
    $e2 = str_replace('"','',$e2); 
    $e2 = explode(":", $e2);        // take only name node 
}

if ($e1 == 'tree'){ 
    if ($_SESSION['username'] !== $e2){ // verification right name user
        $return_data['key1'] = 'error';
        $return_data['key2'] = ' tree authentication problem';
        echo json_encode($return_data);
        return;
    }
    echo json_encode(listFolders()); // here i want put $e2 = name user
    return ;
}

function listFolders($dir = __DIR__ . '/datausers_tmp/tree_ckeditor') {
    $dh = scandir($dir);
    $return = [];
    
    foreach ($dh as $folder) {
        if ($folder != '.' && $folder != '..') {
            $Folder_data = "/datausers/tree_ckeditor";
            
            if (is_dir($dir . '/' . $folder)) { // it's a folder
                $return[] = array(
                    'title' => $folder,
                    'folder' => true,
                    'expanded'=> true,
                    'children' => listFolders($dir . '/' . $folder, $key)
                );
            } else { // it's a file
                $return[] = [
                    'title' => $folder,
                    'title' => $folder,
                ];
            }
        }
    }
    return $return;
}
?>

currently the best result gives me this, with code in my firts post :

ok now it almost works. My output (checked with http://jsonviewer.stack.hu/ - click to expand all)

[{"title":"PERSONNAL","folder":true,"expanded":true,"children":[{"title":"Peter","folder":true,"expanded":true,"children":[{"title":"guitar","folder":true,"expanded":true,"children":[{"title":"tabs"}]}]}]},{"title":"TEAM","folder":true,"expanded":true,"children":[{"title":"contact","folder":true,"expanded":true,"children":[{"title":"Phone"}]},{"title":"information","folder":true,"expanded":true,"children":[{"title":"technique"}]}]}]

I added this line to take that one user:
if ($ item === $name_user) {// Take only a user

now, how to give in the function the variable $name_user and avoid repetitions ?

my last code : 

<?php
$name_user = 'Peter'; // currently not used :-( 
echo json_encode(listFolders());

function listFolders($dir = __DIR__ . '/datausers') {
    $dh = scandir($dir);
    $name_user = "Peter";
    $return = [];

    if (strpos($dir, "/datausers/PERSONNAL") !== false){ // PERSONNAL found !
        if ($dir === __DIR__ . '/datausers/PERSONNAL') {  
            foreach ($dh as $item) {
                if ($item != '.' && $item != '..') {
                    if ($item === $name_user){ // Take only a user
                        if (is_dir($dir . '/' . $item)) { // it's a folder
                            $return[] = array(
                                'title' => $item,

                                'expanded'=> true,
                                'children' => listFolders($dir . '/' . $item, $key)
                            );
                        } else { // it's a file
                            $return[] = [

Ok I found the solution.
It's crazy I spent the day yesterday on this problem.
and today I finally find the solution. Thank you requinix for answering me.

I put here my solution (not perfect) but it works.

<?php
if(session_status() != 2) {	session_start(); } else { header('Location: deco.php'); } // (2 = session active) if don't active session
if (!isset($_SESSION['username']) || empty($_SESSION['username'])) {header('Location: deco.php');} // redirection si pas de session ouverte
if (time() > $_SESSION['expire']) {
    session_destroy();
    header('Location: deco.php');
}
$e1 = isset($_POST['e1']) ? $_POST['e1'] : null;
$e2 = isset($_POST['e2']) ? $_POST['e2'] : null;
if (empty($e1) || empty($e2)) {
    $return_data['key1'] = 'error';
    echo json_encode($return_data);
    return;
}

if ($e1 == 'read'){
    $e2 = str_replace('<','',$e2); // just for prevent html injection
    $e2 = str_replace('?','',$e2); // just for prevent php injection
    $return_data['key1'] = 'read';
    $return_data['key2'] = $e2;
    echo json_encode($return_data);
    return;

    $e2 = str_replace('}','',$e2); 
    $e2 = str_replace('"','',$e2); 
    $e2 = explode(":", $e2);        // take only name node 
}

if ($e1 == 'tree'){ 
    if ($_SESSION['username'] !== $e2){ // verification right name user
        $return_data['key1'] = 'error';
        $return_data['key2'] = ' tree authentication problem';

    }
    echo json_encode(listFolders($e2, __DIR__ . '/datausers')); // $e2 = name user

Otherwise build a tree structure with a different directory level and a filter of the directories to be taken.
if it can help someone

Root

$e2 = "name folder";
$path_array = explode('/', __DIR__); // put path to array

On an unrelated note, if you're trying to redirect a user away because they do not have permission to access the page, you need to exit; after your call to header() otherwise the script will keep going and still do whatever it is they are not supposed to be doing.

 

On a more related note, you code could probably be cleaned up a lot if you switched to using RecursiveDirectoryIterator / RecursiveFilterIterator.  For example:

<?php

class PrefixFilter extends RecursiveFilterIterator {
    private $prefixList;

    public function __construct(RecursiveIterator $iterator, array $prefixList){
        parent::__construct($iterator);
        $this->prefixList = $prefixList;
    }

    public function accept() : bool{
        /** @var SplFileInfo $current */
        $current = $this->current();
        $path = $current->getPathname();
        $path = strtr($path, '\\', '/');

        $pathLength = strlen($path);
        foreach ($this->prefixList as $prefix){
            $length = min(strlen($prefix), $pathLength);
            if (strncmp($path, $prefix, $length) === 0){
                return true;
            }
        }

        return false;
    }

    public function getChildren() : RecursiveFilterIterator{
        return new self($this->getInnerIterator()->getChildren(), $this->prefixList);
    }
}


header('Content-type: text/plain');
$root = './datausers';
$prefixList = [
  $root . '/TEAM',
  $root . '/PERSONAL/' . strtoupper($_GET['user'])
];

echo 'Found the following files for the selected user:', PHP_EOL;
$iter = new RecursiveDirectoryIterator($root);
$iter = new PrefixFilter($iter, $prefixList);
$iter = new RecursiveIteratorIterator($iter);
foreach ($iter as $item){
  if ($item->isDir() && $item->getFilename() === '.'){
    echo 'Directory: ', $item->getPath(), PHP_EOL;
  } else if ($item->isFile()){
    echo 'File: ', $item->getPathname(), PHP_EOL;
  }
}

The directory iterator takes care of scanning the directories and you can choose what you want/don't want with the filter class.  Here it's based on a simple prefix filter but you could make it more complex if needed.  Once all that's setup getting the list of files and folders is a simple foreach loop over the iterator.
