以相同的形式提交和保存 PDF 文件和 JPG/PNG 文件

Question

我有一个表单，用户应该能够在一个输入中上传图像，在另一个输入中上传 PDF。他们只能上传一个或另一个。我的问题是，由于我添加了 PDF 字段，用户无法再上传图像。数据库仍在检索图像名称，但尚未将图像上传到服务器。

视图中的我的表单：

 <?= $this->Form->create($work, ['class'=> 'worksform', 'enctype'=>'multipart/form-data']) ?>

<?= $this->Html->image('upload.png', ['class' => 'uploadform center']); ?>

<div class="worksformname"><?= $this->request->session()->read('Auth.User.first_name')?> <?= $this->request->session()->read('Auth.User.last_name');?></div>

<fieldset>
        <div class= "worksformtitle"><?= $this->Form->control('Title');?></div>

        <div class= "worksformcourse"><?= $this->Form->control('course_id', ['options' => $courses]);?></div>

        <div class= "worksformunit"><?= $this->Form->control('unit_id', ['options' => $units]); ?></div>

        <div class= "worksformdesc" data-container="body"><?= $this->Form->control('description');?></div>

        <p class="worksformtext">I want to upload a... </p>

        <li class="buttonworks">
        <button type="button" class="videoworks"id="videob"> Video Project </button>
        <button type="button" class="audioworks" id="audiob">  Audio Project</button>
        <button type="button" class="pdfworks" id="pdfb"> PDF File </button>
        <button type="button" class="imageworks" id="imageb"> Image File </button> </li>

        <div class="worksformvideo d-none" id="videof" data-container="body"><?= $this->Form->control('video_url')?> </div>

        <div class="worksformvideo d-none" id="audiof" data-container="body" ><?= $this->Form->control('sound_url');?> </div>

        <div class="worksformvideo d-none"id="pdff"><?= $this->Form->control('pdf', ['type'=> 'file'])?> </div>

        <div class="worksformvideo d-none"id="imagef"><?= $this->Form->control('image', ['type'=> 'file'])?> </div>
</fieldset>
<div class="buttonbox">
   <?=$this->Form->button(__('Submit')) ?>
    </div>
<?= $this->Form->end() ?>

控制器：

public function add()
{
    $work = $this->Works->newEntity();

    if ($this->request->is('post')) {
        $work = $this->Works->patchEntity($work, $this->request->getData());
        $work->user_id = $this->Auth->user('id');

        $file =$this->request->data['image'];
        $name =$this->request->data['image']['name'];

        $work->image_url = $name;

        $file =$this->request->data['pdf'];
        $name1 =$this->request->data['pdf']['name'];

        $work->pdf_url = $name1;

        if ($this->Works->save($work)) {
            move_uploaded_file($file['tmp_name'], WWW_ROOT . 'files/' . $name);
            $this->Flash->success(__('The work has been saved.'));

            move_uploaded_file($file['tmp_name'], WWW_ROOT . 'files/' . $name1);
           $this->Flash->success(__('The work has been saved.'));

            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('The work could not be saved. Please, try again.'));
    }
    $users = $this->Works->Users->find('list', ['limit' => 200]);
    $units = $this->Works->Units->find('list', ['limit' => 200]);
    $courses = $this->Works->Courses->find('list', ['limit' => 200]);
    $this->set(compact('work', 'users', 'units', 'courses'));


}

视图中的输出：

Answer 1

如cmets中所说，问题出在：

    $file =$this->request->data['image'];
    $name =$this->request->data['image']['name'];

    $work->image_url = $name;

    $file =$this->request->data['pdf'];
    $name1 =$this->request->data['pdf']['name'];

    $work->pdf_url = $name1;

所以$file 总是等于 pdf 数据。您需要将其更改为：

if ($this->request->data['image']) {
    $file =$this->request->data['image'];
    $name =$this->request->data['image']['name'];

    $work->image_url = $name;
} else ($this->request->data['pdf']) {
    $file =$this->request->data['pdf'];
    $name1 =$this->request->data['pdf']['name'];

    $work->pdf_url = $name1;
}
