Question

我试图使用cakephp上传图片，我收到以下错误：

注意（8）：数组到字符串转换[CORE \ Cake \ Model \ Datasource \ DboSource.php，第1009行]

<?php echo $this->Form->create('User',array('type'=>'file')); 
      echo $this->Form->input('profile_pic', array('type'=>'file')); 
      echo $this->Form->end('submit');
?>

我所做的事情有什么不对吗？

Answer 1

您需要在控制器中处理文件上传。如果您调试请求，您将看到profile_pic字段是一个数组：

# in controller:
if ($this->request->is('post')) {
            debug($this->request->data); die();
        }

# result:
array(
    'User' => array(
        'profile_pic' => array(
            'name' => 'wappy500x500.jpg',
            'type' => 'image/jpeg',
            'tmp_name' => '/tmp/phptk28hE',
            'error' => (int) 0,
            'size' => (int) 238264
        )
    )
)

简短回答：

public function upload() {
        if ($this->request->is('post')) {
            if(isset($this->request->data['User']['profile_pic']['error']) && $this->request->data['User']['profile_pic']['error'] === 0) {
                $source = $this->request->data['User']['profile_pic']['tmp_name']; // Source
                $dest = ROOT . DS . 'app' . DS . 'webroot' . DS . 'uploads' . DS;   // Destination
                move_uploaded_file($source, $dest.'your-file-name.jpg'); // Move from source to destination (you need write permissions in that dir)
                $this->request->data['User']['profile_pic'] = 'your-file-name.jpg'; // Replace the array with a string in order to save it in the DB
                $this->User->create(); // We have a new entry
                $this->User->save($this->request->data); // Save the request
                $this->Session->setFlash(__('The user has been saved.')); // Send a success flash message
            } else {
                $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
            }

        }
    }

当然，您需要对上传的文件进行额外验证。

你正确学习cakephp手册如何表格类型可以是文件?????? ：）

使用此

<?php echo $this->Form->create('User',array('enctype'=>'multipart/form-data')); 
      echo $this->Form->input('profile_pic', array('type'=>'file')); 
      echo $this->Form->end('submit');
?>
