Fancytree

Question

我正在使用 Fancytree，我想生成一个 file/folder 树，但要排除所有不是来自当前用户的文件夹。

示例：

UPPERCASE = FOLDER
lowercase = file

我想用用户“Peter”创建一个树结构

我有几个问题：

我不明白listFolders这个函数，不能给它一个参数（比如$name_user）否则不能用
行 >> print_r ('TAKE THIS'. $ Dir); << 显示了我想要拍摄的内容，但 foreach 行不通
我的代码重复了，因为我无法在函数内部创建函数...

这是我的代码：

    <?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('TAKE THIS' . $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('TAKE THIS' . $dir);
                echo '</br>';

好的，我找到了解决方案。昨天我花了一天时间解决这个问题真是太疯狂了。今天我终于找到了解决办法。谢谢 requinix 回复我。

我把我的解决方案（不完美）放在这里，但它有效。

<?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 
}

否则构建一个具有不同目录级别的树结构和要获取的目录的过滤器。
如果它可以帮助某人:)

根目录
--Admin [此处PHP脚本]
--Datauser [这里取树结构]

$e2 = "name folder";
$path_array = explode('/', __DIR__); // put path to array
$path_shortcut_array = array_slice($path_array,0,(count($path_array)-1)); // rebuild array path without the last 
$path_base_string = implode("/", $path_shortcut_array); // rebuild with '/'

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

function listFolders($path_user, $dir) {
    $dh = scandir($dir);
    $name_user = $path_user;
    $return_data = [];

    if (strpos($dir, "/datausers/PERSONNAL") !== false){ // PERSONNAL found !
        $path_array = explode('/', __DIR__);
        $path_shortcut_array = array_slice($path_array,0,(count($path_array)-1));
        $path_base_string = implode("/", $path_shortcut_array);
        
        if ($dir === $path_base_string . '/datausers/PERSONNAL') {  
            foreach ($dh as $item) {
                if ($item != '.' && $item != '..') {
                    if ($item === $name_user){ // Take only a user
                        if (is_dir($dir . '/' . $item)) { // it's a folder
