文件上传 CakePHP 3.4

Question

我试图从表单上传一个简单的文件以保存在我的 webroot/img 文件夹中，但是我遇到了一些困难。

这是视图中的表单：

<?= $this->Form->create($productImage) ?>
<fieldset>
    <legend><?= __('Add Product Image') ?></legend>
    <?php
        echo $this->Form->control('product_id', ['options' => $products]);
        echo $this->Form->file('image', ['label' =>'','size'=>'50']); //Uploaded file
        echo $this->Form->control('image_path');
    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

这是控制器中的功能：

    public function add()
{
    $productImage = $this->ProductImages->newEntity();
    if ($this->request->is('post')) {
        $image = $this->request->data['image'];
        if (move_uploaded_file($image,WWW_ROOT . '/img')) {
            $this->Flash->success(__('file upload successful'));
        } else {
            $this->Flash->success(__('file upload unsuccessful'));
        }
        $productImage = $this->ProductImages->patchEntity($productImage, $this->request->getData());

        if ($this->ProductImages->save($productImage)) {
            $this->Flash->success(__('The product image has been saved.'));

            return $this->redirect(['action' => 'index']);
        }
        $this->Flash->error(__('The product image could not be saved. Please, try again.'));
    }
    $products = $this->ProductImages->Products->find('list', ['limit' => 200]);
    $this->set(compact('productImage', 'products'));
    $this->set('_serialize', ['productImage']);
}

move_uploaded_file 一直返回 false，我不知道为什么。

非常感谢您的帮助。

你必须关心两件事

1.正确的声明

在您的 html 表单中添加 enctype="multipart/form-data" (['type' => 'file']) 在 CakePHP 表单中创建。那么你的代码将是

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

2。上传图片

以正确的方式上传图片 使用
$this->request->data['image']['name'];
