Cake上传图片在Cake PHP的“webroot/img”文件夹中

"我想在蛋糕 php 的 webroot/img 文件夹中上传图像，但我无法 建议我一些解决方案，因为我是蛋糕PHP的新手。我从我的 但没有什么 works.so 帮助我">

my HomesController.php code as
public function admin_add() {
    if ($this->request->is('post')) {
        $this->Home->create();
         $image = $this->request->data['Home']['image'];
         //$imageTypes = array("image/gif", "image/jpeg", "image/png");
         //$uploadFolder = "upload";
         //$uploadPath = WWW_ROOT . $uploadFolder;
         pr($this->request->data);
         //echo $image['type'];
         if ($this->Home->save($this->request->data)) {
            $this->Session->setFlash(__('The home has been saved.'));
            //echo pr($this->request->data);
            //echo die(debug($this->request->data));
            //return $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The home could not be saved., tryagain '));
        }
    }
}

admin_add.ctp 代码是

<div class="homes form">
<?php echo $this->Form->create('Home', array('type' => 'file')); ?>
<fieldset>
    <legend><?php echo __('Add Home content'); ?></legend>
<?php
    echo $this->Form->input('title');
    echo $this->Form->input('body');
    echo $this->Form->input('image');
?>
</fieldset>

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

运行代码时，我无法上传图像，并且在打印图像数据时我收到错误。

Output:

`Array
    (
    [Home] => Array
        (
            [title] => vhbk
             [body] => ,bjljbl.
             [image] => Array

            )
         )
