我是cakephp的新手,我正在尝试使用cakephp创建一个简单的文件上传2.3这里是我的控制器
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 $this->Form->end('Submit')
它保存了数据库中的名字,姓氏,关键字和文件名,但是我要保存在app / webroot / documents中的文件没有保存,有人可以帮忙吗?感谢
更新
thaJeztah我按照你说的做了但是如果我没错的话,它会给出一些错误
public function add() {
if ($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.');
}
}
}
和我的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')
,错误是
注意(8):数组到字符串的转换 [CORE \ Cake \ Model \ Datasource \ DboSource.php,第1005行]
数据库错误错误:SQLSTATE [42S22]:找不到列:1054未知 “字段列表”中的“数组”列
SQL查询:INSERT INTO first.posts(firstname,lastname,keywords, doc_file)VALUES('dfg','cbhcfb','dfdbd',Array)
和Victor我也做了你的版本,它也不起作用。
答案 0 :(得分:14)
您似乎使用了错误的“密钥”来访问发布的数据;
$this->data['posts'][....
应匹配您Model的'别名'; 单数和 captial 第一个字母
$this->data['Post'][....
此外,$this->data
是$this->request->data
的向后兼容性包装器,所以最好使用它;
$this->request->data['Post'][...
要检查发布数据的内容并了解其结构,您可以使用此进行调试;
debug($this->request);
确保启用调试,方法是将debug
设置为1
或2
内的app/Config/core.php
我刚刚注意到你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'));
嵌套表单将从不工作,删除该行并添加'type =>将文件'发送到第一个Form->create()
“数组到字符串转换”问题是由于您尝试直接将“doc_file”数据用于数据库这一事实。因为这是一个文件上传字段,'doc_file'将包含 Array 数据('name','tmp_name'等)。
对于数据库,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。
以示例这种方式;
// 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;

..确保文件目录已存在并检查您是否有权写入该文件目录?如果它不存在则创建它或在您的代码中检查它是否存在并创建它,如果它不存在: 将检查目录是否存在的代码示例并创建它然后上传文件 -
$dir = WWW_ROOT. DS . 'documents';
if(file_exists($dir) && is_dir($dir))
{
move_uploaded_file($this->data['posts']['doc_file']['tmp_name'],$filename);
}
elseif(mkdir($dir,0777))
{
move_uploaded_file($this->data['posts']['doc_file']['tmp_name'],$filename);
}
还确保您没有上传空白/空文件 - 它可能会失败。

只是因为有人再次搜索它。这是我的代码(在Cakephp 2.5.5上测试和使用)。它基于http://www.templemantwells.com.au/article/website-development/cakephp-image-uploading-with-database& http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html#FormHelper::file
查看文件(* .ctp)
<?php
echo $this->Form->create('Image', array('type' => 'file'));
?>
<fieldset>
<legend><?php echo __('Add Image'); ?></legend>
<?php
echo $this->Form->input('Image.submittedfile', array(
'between' => '<br />',
'type' => 'file',
'label' => false
));
// echo $this->Form->file('Image.submittedfile');
?>
</fieldset>
<?php echo $this->Form->end(__('Send My Image')); ?>
控制器功能(* .php)
public function uploadPromotion() {
// Custom
$folderToSaveFiles = WWW_ROOT . 'img/YOUR_IMAGE_FOLDER/' ;
if (!$this->request->is('post')) return; // Not a POST data!
if(!empty($this->request->data))
{
//Check if image has been uploaded
if(!empty($this->request->data['Image']['submittedfile']))
{
$file = $this->request->data['Image']['submittedfile']; //put the data into a var for easy use
debug( $file );
$ext = substr(strtolower(strrchr($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
$newFilename = $file['name']; // edit/add here as you like your new filename to be.
$result = move_uploaded_file( $file['tmp_name'], $folderToSaveFiles . $newFilename );
debug( $result );
//prepare the filename for database entry (optional)
//$this->data['Image']['image'] = $file['name'];
}
}
//now do the save (optional)
//if($this->Image->save($this->data)) {...} else {...}
}
}

我已经找到了从CakePHP上传文件和图片的完整指南 - Handling File Uploads in CakePHP
示例代码如下所示。
<强>控制器:强>
$fileName = $this->request->data['file']['name'];
$uploadPath = 'uploads/files/';
$uploadFile = $uploadPath.$fileName;
if(move_uploaded_file($this->request->data['file']['tmp_name'],$uploadFile)){
//DB query goes here
}

<?php echo $this->Form->create($uploadData, ['type' => 'file']); ?>
<?php echo $this->Form->input('file', ['type' => 'file', 'class' => 'form-control']); ?>
<?php echo $this->Form->button(__('Upload File'), ['type'=>'submit', 'class' => 'form-controlbtn btn-default']); ?>
<?php echo $this->Form->end(); ?>
