upload a file in cakePHP - cakephp

Question

Hi I want to upload a file using cake php, i got the file and i am using
move_uploaded_file() to move to a specific location but it is not moving my simple logic is
shown below
if (move_uploaded_file($this->data['Add']['upload']['tmp_name'], APP . 'views' . DS .
'static' . DS.'uploads'.DS.'Rajaram'.DS )) {
LogUtil::$logger->debug('KMP File upload Url :
'.var_export($this->data, true));
}
Thanks in Advance.

File uploading is something CakePHP doesn’t do out of the box, which is one of the only thing that annoys me about the framework.
I tackled this by adding file handling to a model using callback methods. I upload the actual file with beforeSave(), and delete the file from the file system with beforeDelete(). A sample model looks like this:
<?php
App::uses('File', 'Utility');
class Image extends AppModel {
public $name = 'Image';
public function beforeSave($options = array()) {
$fieldName = 'filename';
$field = $this->data[$this->alias][$fieldName];
if (!is_array($field)) {
$this->validationErrors[$fieldName][] = 'No file detected';
return false;
}
switch ($field['error']) {
case UPLOAD_ERR_OK:
$newFilename = time() . '.jpg';
$uploadDir = WWW_ROOT . 'files/';
$source = $field['tmp_name'];
$destination = $uploadDir . $newFilename;
if (move_uploaded_file($source, $destination)) {
$this->data[$this->alias][$fieldName] = $newFilename;
return true;
}
else {
$this->validationErrors[$fieldName][] = 'No file detected';
return false;
}
break;
default:
$this->validationErrors[$fieldName][] = 'No file detected';
return false;
break;
}
}
public function beforeDelete($cascade = true) {
$image = $this->findById($this->id);
$file = new File(WWW_ROOT . 'files/' . $image['Image']['filename']);
return $file->delete();
}
}
Obviously this isn’t a perfect implementation, so feel free to take from it, learn from it, adapt it.
This was written off-the-cuff for a project recently where there’s only one model that has images attached, but on a larger project I’d more than likely wrap it up into a nice model behavior.

In your model you can use the afterSave callback method to handle your file upload:-
public function afterSave($created) {
if (isset($_FILES['data']['name'][$this->alias]['filename'])) {
$filename = $_FILES['data']['name'][$this->alias]['filename'];
$fileInfo = pathinfo($filename);
$fileExt = isset($fileInfo['extension']) ? $fileInfo['extension'] : '';
$filename = $fileInfo['filename'];
$newFilename = "$filename.$fileExt";
$dir = WWW_ROOT . 'files' . DS . 'uploads';
$target = $dir . DS . $newFilename;
move_uploaded_file($source, $target);
}
}
You can use $newFilename to change the filename to something appropriate if need be (I tend to check if a file with the same name already exists and rename the new one to avoid overwriting it.
