cakephp - 无法让 CakePHP 3.8 多文件上传工作

Question

我正在做这个项目，起初它有一个非常好的单个文件上传，但不得不更改为多个文件上传，现在我无法让它工作！收到“标题已发送”错误：

Deprecated (16384): Accessing `here` as a property will be removed in 4.0.0. Use request->getAttribute("here") instead. - /home1/thecyb80/seibo.the-cyberpunk.com/src/Controller/AppController.php, line: 92
 You can disable deprecation warnings by setting `Error.errorLevel` to `E_ALL & ~E_USER_DEPRECATED` in your config/app.php. [CORE/src/Core/functions.php, line 311]

这是我的代码：add.ctp

<?= $this->Form->create($atividade, ['type' => 'file']) ?>

[...]

<div class="form-group m-0">
    <label class="btn btn-light p-3 rounded border d-flex align-items-center justify-content-center flex-column" style="cursor: pointer; min-height: 350px;">
        <strong class="d-block">Selecione o(s) arquivo(s) da atividade. Você pode enviar até 10 arquivos.</strong>
        <span class="exercicio-nome d-flex aling-items-center justify-content-center w-100 mt-3"></span>
        <?= $this->Form->file('arquivos[]', [ 'class' => 'exercicio-item', 'multiple' => 'multiple', 'style' => 'display: none;', 'label' => [ 'class' => 'd-none' ] ]) ?>
    </label>
</div>

验证成立于AtividadesTable.php（这是该字段的唯一出现）：

$validator
    ->scalar('arquivos')
    ->maxLength('arquivos', 255)
    ->allowEmptyString('arquivos')
    ->allowEmptyFile('arquivos');

我尝试了几种解决方案，我在互联网上找到了这些解决方案，但没有一个对我有帮助。我在 PHP 7.2.31 上使用 CakePHP 3.8.11。

这是我composer.json安装的模块（不知道是否有帮助）：

"require": {
    "php": ">=5.6",
    "cakephp/cakephp": "3.8.*",
    "cakephp/migrations": "^2.0.0",
    "cakephp/plugin-installer": "^1.0",
    "mobiledetect/mobiledetectlib": "2.*"
}

由于我无法完成这一步，我假设现在，我的控制器是无关紧要的。我能做些什么？

多文件上传（上传4个文件）

使用

<?= $this->Form->file('arquivos[]', [ 'class' => 'exercicio-item', 'multiple' => 'multiple', 'style' => 'display: none;', 'label' => [ 'class' => 'd-none' ] ]) ?>

输出

单个文件上传

使用

<?= $this->Form->file('arquivos[]', [ 'class' => 'exercicio-item', 'multiple' => 'multiple', 'style' => 'display: none;', 'label' => [ 'class' => 'd-none' ] ]) ?>

Atividades控制器

我将展示我的AtividadesController.php（添加方法）：

/**
* Add method
*
* @return \Cake\Http\Response|null Redirects on successful add, renders view otherwise.
*/
public function add($nivelId = null)
{
    $atividade = $this->Atividades->newEntity();

    if ($this->request->is('post')) {

        // Edit - StackOverflow
        debug($this->getRequest()->getData()); exit;

        $atividade = $this->Atividades->patchEntity($atividade, $this->request->getData());

        die(debug($_FILES));

        // Salvando os arquivos
        if (!empty($_FILES['arquivos']['name'])) {
            $file = $_FILES['arquivos'];
            $arquivoName = $file['name'];
            $userId = $this->Auth->user('id');

            $ext = substr(strtolower(strrchr($arquivoName, '.')), 1);
            $arr_ext = array('zip', 'rar', 'pdf', 'doc', 'docx', 'ppt', 'pptx');

            if (in_array($ext, $arr_ext)) {
                $imgHashed = md5($arquivoName) . time() . '.' . $ext;
                $fileDir = WWW_ROOT . 'files/' . $userId;

                if (!is_dir($fileDir)) {
                    mkdir($fileDir);
                }

                @move_uploaded_file($file['tmp_name'], $fileDir . '/' . $imgHashed);

                $atividade['arquivos'] = $imgHashed;
                $atividade['arquivo_nome'] = $arquivoName;
            } else {
                $this->Flash->error(__("Só aceitamos imagens dos tipos 'zip', 'rar', 'pdf', 'doc', 'docx', 'ppt' ou 'pptx'."));

                return $this->redirect(['action' => 'add']);
            }
        }

        if ($this->Atividades->save($atividade)) {
            $this->Flash->success(__('A atividade foi salva.'));

            return $this->redirect(['action' => 'index', $this->Auth->user('id')]);
        }
        $this->Flash->error(__('A atividade não pode ser salva. Por favor, tente novamente.'));
    }

    $arquivos = $this->Atividades->Arquivos->find('list');
    $materias = $this->Atividades->Materias->find('list');

    if ($nivelId) {
        $turmas = $this->Atividades->Turmas->find('list')->matching('Nivels', function($q) use ($nivelId) {
            return $q
                ->select()
                ->where(['Nivels.id' => $nivelId]);
        });
    } else {
        $turmas = $this->Atividades->Turmas->find('list');
    }
    $users = $this->Atividades->Users->find('list')->where(['tipo' => 'professor']);
    $this->set(compact('atividade', 'arquivos', 'materias', 'turmas', 'users'));
}

我错过了什么吗？一些 CakePHP 组件，也许吧？一些 PHP 扩展？
