image - 蛋糕PHP图片上传

Question

我是蛋糕 PHP 的新手，我需要一些上传图片的帮助。我需要允许用户上传图像，我希望该图像保存在目录中(www/CakePHP/app/webroot/img/)，并且还希望数据库存储图像的文件路径。这是我到目前为止所得到的

产品ADD.ctp:

<div class="products form">
<?php echo $this->Form->create('Product'); ?>


    <fieldset>
        <legend><?php echo __('Add Product Details'); ?></legend>
    <?php
        echo $this->Form->input('product_name', array('required'=>false));
        echo $this->Form->input('product_model_number', array('required'=>false));
        echo $this->Form->input('product_brand', array('required'=>false));
        echo $this->Form->input('product_description', array('required'=>false));
        echo $this->Form->input('price_bronze', array('required'=>false));
        echo $this->Form->input('price_silver', array('required'=>false));
        echo $this->Form->input('price_gold', array('required'=>false));
        echo $this->Form->input('upload', array('type'=>'file'));


    ?>
    </fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>

产品 Controller :

   public function add() {
            if ($this->request->is('post')) {
                $this->Product->create();
                if ($this->Product->save($this->request->data)) {
                    $this->Session->setFlash(__('The product has been saved.'));
                    return $this->redirect(array('action' => 'index'));
                } else {
                    $this->Session->setFlash(__('The product could not be saved. Please, try again.'));
                }
                if(!empty($this->data))
                {
                    //Check if image has been uploaded
                    if(!empty($this->data['products']['upload']['name']))
                    {
                        $file = $this->data['products']['upload']; //put the data into a var for easy use

                        $ext = substr(strtolower(strrchr($file['name'], '.')), 1); //get the extension
                        $arr_ext = array('jpg', 'jpeg', 'gif'); //set allowed extensions

                        //only process if the extension is valid
                        if(in_array($ext, $arr_ext))
                        {
                            //do the actual uploading of the file. First arg is the tmp name, second arg is
                            //where we are putting it
                            move_uploaded_file($file['tmp_name'], WWW_ROOT . 'CakePHP/app/webroot/img/' . $file['name']);

                            //prepare the filename for database entry
                            $this->data['products']['product_image'] = $file['name'];
                        }
                    }

                    //now do the save
                    $this->products->save($this->data) ;
                }
            }

        }

我似乎无法弄清楚为什么上传的图像没有保存到目录中。有人可以帮忙吗。

在带有文件输入的 cakephp 中创建新表单时，您必须设置 'enctype'=>'multipart/form-data'

代码应该是这样的:

<?php echo $this->Form->create('Product',array('enctype'=>'multipart/form-data')); ?>

我希望这会奏效
