Upload file Yii The second argument to copy() function cannot be a directory - upload

Question

I'm trying to upload file but get this error message :
move_uploaded_file() [<a href='function.move-uploaded-file'>function.move-uploaded-file</a>]: The second argument to copy() function cannot be a directory
I think there's something problem with this file but I've no idea to solve it..
<?php
class FileUploadController extends CController {
public function actionUpload() {
$model = new FileUpload();
$form = new CForm('application.views.fileUpload.uploadForm', $model);
if ($form->submitted('submit') && $form->validate()) {
$form->model->image = CUploadedFile::getInstance($form->model, 'image');
if($model->validate())
{
$model->image->saveAs('/opt/lampp/htdocs/upl/images');
Yii::app()->user->setFlash('success', 'File Uploaded');
$this->redirect(array('upload'));
}
}
$this->render('upload', array('form' => $form));
}
}
?>

Answer 1

You either need to check all files existed at '/opt/lampp/htdocs/upl/images' and check if the same named file is available or not, if available then just rename the file with extra "_1" every time, or you can always upload the file by renaming the file into some machine name sort of thing see the code below,
$name = rand(1000,9999) . time(); // rand(1000,9999) optional
$name = md5($name); //optional
$model->image->saveAs('/opt/lampp/htdocs/upl/images/' . $name . '.jpg');
This is what I usually do with file uploads, provided that you're saving the files references into the database or in any text file.
EDIT
Get Extension.
In case if you're required to get extension of the file rather then of hard-coded, you can use $model->image->getExtensionName(); it will get you the extension of the uploaded file without . (dot)

Finally, I solved it by myself:
The problem was located in line
$model->image->saveAs('/opt/lampp/htdocs/upl/images');
It should be :
$model->image->saveAs('/opt/lampp/htdocs/upl/images/images.jpg');
Now, there's another problem: when I upload 'new image', it will be replace the old file, I want the file(s) being uploaded not replaced the old file or I need something like rename as new file. Does anyone knows?

goto cuploadedfile.php .
over write this function with this
if($this->_error==UPLOAD_ERR_OK)
{
if($deleteTempFile)
return move_uploaded_file($this->_tempName,$file."/".$this->getName());
elseif(is_uploaded_file($this->_tempName))
return copy($this->_tempName, $file."/".$this->getName());
else
return false;
}
thank u.........
