Question

关注Prassanna D's method to upload files on CakePHP 3.x，我做了类似的事情：

public function upload()
{
    $uploadData = $this->Files->get($id,[
        'contain' => ['Sessions']
    ]);
    if($this->request->is(['patch', 'put', 'post'])){
        if (!empty($this->request->data)) {
        if (!empty($this->request->data['link']['name'])) {
        $file = $this->request->data['link']; 
        $ext = substr(strtolower(strrchr($file['name'], '.')), 1); 
        $arr_ext = array('xls', 'xlsx'); //set allowed extensions
        $datestart = $uploadData->session->datestart;
        $dateend = $uploadData->session->dateend;
        $setNewFileName = 'file'.$datestart.'-'.$dateend;

        if (in_array($ext, $arr_ext)) {
            move_uploaded_file($file['tmp_name'], WWW_ROOT . '\uploads\files' . DS. $setNewFileName . '.' . $ext);

            $filesFileName = $setNewFileName . '.' . $ext;
            }
        }

        $getFormvalue = $this->Files->patchEntity($uploadData, $this->request->data);

        if (!empty($this->request->data['link']['name'])) {
            $getFormvalue->name = $filesFileName;
            $getFormvalue->link = 'uploads/files';
        }


        if ($this->Files->save($getFormvalue)) {
           $this->Flash->success('Your file has been successfully uploaded.');
           return $this->redirect(['controller' => 'pages', 'action' => 'display', 'home']);
           } else {
           $this->Flash->error('File could not be uploaded. Please, try again.');
           }
        }
    }
}

我的上传功能查看：

<?php echo $this->Form->create($uploadData, ['type' => 'file']); ?>
<?php echo $this->Form->input('link', ['type' => 'file', 'class' => 'form-control', 'label' => 'Link' ]); ?><br>
<?php echo $this->Form->button(__('Upload File'), ['type'=>'submit', 'class' => 'btn btn-primary', 'style' => 'width:25%;']); ?>
<?php echo $this->Form->end(); ?>

文件表的模型：

public function validationDefault(Validator $validator)
    {
        $validator
            ->integer('id')
            ->allowEmpty('id', 'create');

        $validator
            ->allowEmpty('link')
            ->add('link',[
            'validExtension' => [
                'rule' => ['extension',['xls', 'xlsx']],
                'message' => __('Only files in Excel formats .xls and .xlsx are allowed')
            ]
    ]);

        $validator
            ->allowEmpty('name');

        return $validator;
    }

当我选择要上传的随机xlsx文件然后单击提交按钮时，在填写相关数据库属性时，文件本身不会上传到uploads目录。

我收到两条与move_uploaded_file相关的警告：

move_uploaded_file(C:\xampp\htdocs\project\webroot\uploads\files\file 1/4/17-9/4/17.xlsx): failed to open stream: No such file or directory
move_uploaded_file() [<a href='http://php.net/function.move-uploaded-file'>function.move-uploaded-file</a>]: Unable to move 'C:\xampp\tmp\php7143.tmp' to 'C:\xampp\htdocs\project\webroot\uploads\files\file 1/4/17-9/4/17.xlsx'

然而，这确实存在。

如果我将move_uploaded_file($file['tmp_name'], WWW_ROOT . '\uploads\files' . DS. $setNewFileName . '.' . $ext);更改为move_uploaded_file($file['tmp_name'], WWW_ROOT . '/uploads/files/'. $setNewFileName . '.' . $ext); - 我收到同样的错误，只有网址显示为move_uploaded_file(C:\xampp\htdocs\project\webroot\/uploads/files/file 1/4/17-9/4/17.xlsx): failed to open stream: No such file or directory

如果我删除$ setNewFileName的所有实例（即我保持原始文件名完整），如下所示：

move_uploaded_file($file['tmp_name'], WWW_ROOT . '/uploads/files/' . $data['link']['name']);
$filesFileName = $data['link']['name'];
$getFormvalue->name = $filesFileName;

我可以让它工作，但我确实想在保存时实际更改文件名，这样当用户下载文件时，它对他们有意义。

更新：忘记我的日期格式是在日期时间。

修复：将我的日期格式化为字符串：

$datestart->format('d-m-y');
$dateend->format('d-m-y');

Move_uploaded_file：无法打开流：没有这样的文件或目录
