Question

我正在尝试使用cakephp 2创建多个文件上传。请提供帮助。我是Cakephp的新手如您所见，我的控制器和视图编码对于单个图像来说都是醒目的。

public function admin_add() {
    if ($this->request->is('post')) {
        $this->Portfolio->create();
        $error_message = $this->Portfolio->checkFileSize($this->request->data);
        if( $error_message === true ) {
            $this->request->data['Portfolio'] = $this->Common->processMedia($this->request->data['Portfolio']);
           //echo '<pre>'; print_r($this->request->data); echo '</pre>';
           // exit();

            if ($this->Portfolio->save($this->request->data)) {

                $this->Session->setFlash(__('The portfolio has been saved'), 'flash_success');

                $this->redirect(array('action' => 'index'));

            } else {

                $this->Session->setFlash(__('The portfolio could not be saved. Please, try again.'), 'flash_error');

            }

        } else {

            $this->Session->setFlash(__($error_message), 'flash_error');

        }

    }

    $talents = $this->Portfolio->Talent->find('list');


    $skills = $this->Portfolio->Skill->find('list', array(

        'order' => array('Skill.name ASC')

    ));

    $this->set(compact('talents', 'skills'));

}

查看-

<input type="file" name="data[Portfolio][media_url_file][]" class=" validate[] m-wrap large" id="PortfolioMediaUrlFile" multiple>

我的数据库结构数据库：-enter image description here

genrated Array-。使用foreach无法启用将此数组保存到数据库中。

Array
(
    [Portfolio] => Array
        (
            [talent_id] => 435
            [title] => asas
            [status] => Approved
            [type_of_media] => picture

                            [error] => 0
                            [size] => 17457
                        )

                    [1] => Array
                        (
                            [name] => unnamed.png
                            [type] => image/png
                            [tmp_name] => /tmp/phpPcqpQw
                            [error] => 0
                            [size] => 14362
                        )

                )

            [media_url] => Array
                (
                    [0] => Array
                        (
                            [name] => wi-logo.png
                            [type] => image/png
                            [tmp_name] => /tmp/phpn8ne7a

                            [size] => 17457
                        )

                    [1] => Array

                        )

                )

Answer 1

如果该文件适用于单个上传，则可以将其扩展为多个。为什么不创建多个输入字段？每个文件都有自己的输入。给每个输入一个唯一的名称，然后在控制器中可以循环引用该输入

$this->request->data['Portfolio1']
$this->request->data['Portfolio2']
$this->request->data['Portfolio3']
...

Answer 2

我想我现在已经明白了这个问题。您想要保存请求的数据，但是您的数据包含数组，该数组不起作用。因此，您必须创建一个与您的db结构匹配的数据数组。在这里，我不明白为什么您有包含相同数据的“文件”和“ mediaurl”。但是这里是我的解决方案：

$this->Portfolio->create();
for($i = 0;$i < $this->request->data['Portfolio'][file];i++){
    $dataArray = [];
    //fill in your data which will be the same for each uploaded file
    $dataArray['talen_id'] = $this->request->data['Portfolio']['talen_id'];
    $dataArray['title'] = $this->request->data['Portfolio']['title'];
    $dataArray['status'] = $this->request->data['Portfolio']['status'];
    $dataArray['picture'] = $this->request->data['Portfolio']['picture'];
    //fill in your data which is different for each uploaded file
    $dataArray['media_url'] = $this->request->data['Portfolio']['media_url'][$i]['name'];
    $dataArray['file'] = $this->request->data['Portfolio']['file'][$i]['name'];
    //now you can save the data
    $this->Portfolio->save($dataArray);
}

cakephp 2上载带有数据的多个文件
