Question

我正在尝试上传用户图片，但是通过以下示例，没有任何内容保存到数据库中，并且没有给出错误。我知道必须完成验证，一旦我将文件存储起来就会完成。

以下是视图文件中的代码段：

<?php 
echo $this->Form->create('User', array('enctype' => 'multipart/form-data'));
echo $this->form->input('upload', array('type' => 'file')); 
echo $this->Form->end('Submit');
?>

控制器：

public function add() {
    if ($this->request->is('post')) {
        if(!empty($this->data['User']['upload']['name'])){
             $file = $this->data['User']['upload'];
             move_uploaded_file($file['tmp_name'], WWW_ROOT . 'img/uploads/users/' . $file['name']);
             $this->data['User']['image'] = $file['name'];
        }                   
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash('The employee has been saved');
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash('The employee could not be saved. Please, try again.');
        }
    }
}

像这样改变你的观点

<?php echo $this->Form->file('Document.submittedfile'); ?>

和您的控制器一样

public function fileupload() {

if ($this->request->is('post') || $this->request->is('put')) {
     //die();
     $file = $this->request->data['Document']['submittedfile'];

     //$this->pdfadd1->save($this->request->data);
     move_uploaded_file($this->data['Document']['submittedfile']['tmp_name'],     $_SERVER['DOCUMENT_ROOT'] . '/cakephp3/cakephp1/cakephp/app/webroot/files/' . $this->data['Document']['submittedfile']['name']);
if ($this->User->save($this->request->data)) {

            $this->Session->setFlash(__('Thanks for the submission'));

            return $this->redirect(array('controller' => 'users','action' => 'index'));
 }
}

忘记在webroot或任何其他地方（对于上传的文件）创建文件夹

文件上传在cakePHP 2.x上不起作用
