cakephp - cakephp 2.3 中的文件上传

Question

我是 cakephp 的新手，我正在尝试使用 cakephp 2.3 创建一个简单的文件上传，这是我的 Controller

public function add() {
    if ($this->request->is('post')) {
        $this->Post->create();
           $filename = WWW_ROOT. DS . 'documents'.DS.$this->data['posts']['doc_file']['name']; 
           move_uploaded_file($this->data['posts']['doc_file']['tmp_name'],$filename);  


        if ($this->Post->save($this->request->data)) {
            $this->Session->setFlash('Your post has been saved.');
            $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash('Unable to add your post.');
        }
     }
 }

和我的add.ctp

echo $this->Form->create('Post');
echo $this->Form->input('firstname');
echo $this->Form->input('lastname');
echo $this->Form->input('keywords');
echo $this->Form->create('Post', array( 'type' => 'file'));
echo $this->Form->input('doc_file',array( 'type' => 'file'));
echo $this->Form->end('Submit')

它在数据库中保存名字、姓氏、关键字和文件名，但我想保存在 app/webroot/documents 中的文件没有保存，任何人都可以帮忙吗？谢谢

Update

thaJeztah i did as u said but it gives some errors here is controller if i'm not wrong

public function add() {
     if ($this->request->is('post')) {
         $this->Post->create();
            $filename = WWW_ROOT. DS . 'documents'.DS.$this->request->data['Post']['doc_file']['name']; 
           move_uploaded_file($this->data['posts']['doc_file']['tmp_name'],$filename);



         if ($this->Post->save($this->request->data)) {
             $this->Session->setFlash('Your post has been saved.');
             $this->redirect(array('action' => 'index'));
         } else {
            $this->Session->setFlash('Unable to add your post.');
         }
     }

 }

and my add.ctp

 echo $this->Form->create('Post', array( 'type' => 'file'));
 echo $this->Form->input('firstname'); echo $this->Form->input('lastname');
 echo $this->Form->input('keywords');
 echo $this->Form->input('doc_file',array( 'type' => 'file'));
 echo $this->Form->end('Submit') 

and the errors are

Notice (8): Array to string conversion [CORE\Cake\Model\Datasource\DboSource.php, line 1005]

Database Error Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Array' in 'field list'

SQL Query: INSERT INTO first.posts (firstname, lastname, keywords, doc_file) VALUES ('dfg', 'cbhcfb', 'dfdbd', Array)

and Victor i did your version too , it doesnt work too .

Answer 1

您似乎使用了错误的“ key ”来访问发布的数据；

$this->data['posts'][....

应与您模型的“别名”匹配； 单数和大写首字母

$this->data['Post'][....

此外，$this->data 是 $this->request->data 的包装器，用于向后兼容，因此最好使用它；

$this->request->data['Post'][...

要检查已发布数据的内容并了解其结构，您可以使用它进行调试；

debug($this->request);

只需确保启用调试，方法是将 app/Config/core.php< 中的 debug 设置为 1 或 2/

更新；重复的表单标签!

我刚刚注意到您还在代码中创建了多个(嵌套)表单；

echo $this->Form->input('keywords');

// This creates ANOTHER form INSIDE the previous one!
echo $this->Form->create('Post', array( 'type' => 'file'));

echo $this->Form->input('doc_file',array( 'type' => 'file'));

嵌套表单永远无法工作，请删除该行并将“type => file”添加到第一个Form->create()

仅使用数据库的文件名称

“数组到字符串转换”问题是由于您尝试直接使用数据库的“doc_file”数据而引起的。因为这是一个文件上传字段，“doc_file”将包含一个数据数组(“name”、“tmp_name”等)。

对于您的数据库，您只需要该数组的“名称”，因此您需要在将数据保存到数据库之前修改数据。

例如这样；

// Initialize filename-variable
$filename = null;

if (
    !empty($this->request->data['Post']['doc_file']['tmp_name'])
    && is_uploaded_file($this->request->data['Post']['doc_file']['tmp_name'])
) {
    // Strip path information
    $filename = basename($this->request->data['Post']['doc_file']['name']); 
    move_uploaded_file(
        $this->data['Post']['doc_file']['tmp_name'],
        WWW_ROOT . DS . 'documents' . DS . $filename
    );
}

// Set the file-name only to save in the database
$this->data['Post']['doc_file'] = $filename;
