Upload a file to specific folder using WordPress - php

I need help for how to upload a file in WordPress, I don't want to upload files into the default path of media files i.e. into uploads/../.., I want to upload my files into wp-content/uploads/my_folder, I just created one file in wp-admin folder and added some functionality there, from that form I want to upload my file (not creating plugin).
Is it possible to do like this? If yes then how? If no then what I want to do for uploading file?
I tried the following solution for it:
$path_array = wp_upload_dir();
$upload_path = $path_array['baseurl'].'/myfoldername/';
$target_path = $upload_path."/".$file_name;
$file_name = $_FILES['fieldname']['name'];
$tmp_name = $_FILES["fieldname"]["tmp_name"];
upload_user_file($_FILES,$upload_path); // Called this function
In functions.php of my theme, I defined the above called function upload_user_file() like as follows:
function upload_user_file( $file = array(),$path) {
if(!empty($file))
{
$uploaded=move_uploaded_file($file['fieldname']['tmp_name'],$path.$file['fieldname']['name']);
if($uploaded)
{
echo "Uploaded successfully ";
}
else
{
echo "Some error in upload ";
print_r($file['error']);
}
}
}
Please help me for this issue.
Thanks.

It's not working because of FILES array loses its values very soon..
Upload it in the same code where you called function it will work...
Thanks cale_b its really helpful.

Removing an image from server

I am trying to delete the images from the server using unlink() function. This is deleting the image name from the database, but the image is not deleted from the server, what am i doing wrong?
public function actionDelete()
{
if(Yii::$app->request->isAjax)
{
$id = $_POST['id'];
$product=Product::find()->where(['id'=>$id])->one()->delete();
$delete=CategoryProduct::find()->where(['product_id'=>$id])->all();
foreach($delete as $del)
{
$del->delete();
}
$imgfile="<?php echo Yii::$app->request->baseUrl;?>/web/assets/uploads/<?php echo $product->image;?>";
unlink($imgfile);
echo json_encode(TRUE);die;
}
echo json_encode(FALSE);die;
}
Its is best to set an alias for the upload path (best place will be config/bootstrap.php)so that we can have standard name to all the upload folder. i.e
Yii::setAlias('image_uploads', dirname(dirname(__DIR__)) . '/web/assets/uploads');
You can use the same for saving and deleting the file.
Saving will be like
move_uploaded_file($tmp_file, \Yii::getAlias('#image_uploads/products/') . $product->image);
or
You can use Yii Methods i.e for e.g.
$this->imageFile->saveAs($orignal_file_full_path); // where imageFile in input type file
Deleting will be something like:
unlink (\Yii::getAlias('#image_uploads/products/') . $product->image);
the Core idea is to use real paths for deleting and saving rather then URLs

How to display a file that is stored on disk using laravel

I am new to laravel and while reading Dayle Rees's book on retrieving data I came across this succinct code for files and storing the file on disk.
Route::post('handle-form', function()
{
$name = Input::file('book')->getClientOriginalName();
Input::file('book')->move('/storage/directory', $name);
return 'File was moved.';
});
My question is how do you display the file that has been stored to the user.
Treat the file as a usual file that you would like people to access with a url.
So suppose that your website's public path is at /var/www/myproject/public, you will want to move the input file into that folder. For example:
Input::file('book')->move('/var/www/myproject/public/uploads', $name);
Then you can display your file with a typical HTML <a> tag:
return 'File was moved. Access your file.';
After uploading the file, you should use Input interface to retrieve the path to your uploaded path. You can get more on it here:
http://laravel.com/docs/requests#files
I will do something like this:
Route::post('handle-form', function()
{
$name = Input::file('book')->getClientOriginalName();
Input::file('book')->move('/storage/directory', $name);
$path = Input::file('book')->getRealPath();
Session::flash("path", $path);
Session::flash("message", "success");
Redirect::to("someRoute");
});
And then in your Message-Route:
Route::get("someRoute", function(){
if(Session::has("message"))
{
?>
<p>You have successfully uploaded a file. Download your file.
</p>
<?php
}
});

$_FILES empty when uploading Magento package

I am trying to install a Magento package, but I get No file was uploaded
Its coming from this code because $_FILES is an empty array in /downloader/Maged/Controller.php
/**
* Install uploaded package
*/
public function connectInstallPackageUploadAction()
{
if (!$_FILES) {
echo "No file was uploaded";
return;
}
if(empty($_FILES['file'])) {
echo "No file was uploaded";
return;
}
$info =& $_FILES['file'];
if(0 !== intval($info['error'])) {
echo "File upload problem";
return;
}
$target = $this->_mageDir . DS . "var/" . uniqid() . $info['name'];
$res = move_uploaded_file($info['tmp_name'], $target);
if(false === $res) {
echo "Error moving uploaded file";
return;
}
$this->model('connect', true)->installUploadedPackage($target);
#unlink($target);
}
It might be worth noting that product uploads work fine.
The only log output I get is
2014-07-03T18:44:15+00:00 ERR (3): Warning: array_key_exists() expects parameter 2 to be array, null given in /var/www/vhosts/example.com/httpdocs/app/code/core/Mage/Captcha/Model/Observer.php on line 166
exception.log was empty
Make sure that your var folder in magento installation is fully writable. 777 permission. All folders and files.
You can try uploading a small dummy file first to check if the error stays the same.
There is a file upload limit which might be reached.
File upload often fails due to upload_max_filesize or post_max_size being too small as mentioned in Common Pitfalls section of the PHP documentation.
Use firebug in firefox to check if your form does has enctype="multipart/form-data".
Check the user group it was created with,
To explain, recently I had some file saving issues. Turned out I had created the folder using the Root user for the server, and the CPanel user ( the one php was running under ) didn't have permission to write in folders owned by the Root account, even when setting the permissions to 777.
Just a thought.
First check if your installation is configured properly
see#http://php.net/manual/en/features.file-upload.common-pitfalls.php
Also, if you upload with PUT/xhr the file is on the input stream
$in = fopen('php://input','r');
see#http://php.net/manual/en/features.file-upload.put-method.php and https://stackoverflow.com/a/11771857/2645347,
this would explain the empty $FILES array, in case all else is ok and the upload works via xhr/PUT.
$_FILES is an associative array of items uploaded to the current script via the HTTP POST method. All uploaded files are stored in $HTTP_POST_FILES contains the same initial information, but is not a superglobal. So, ... be sure that method is POST
Always check that your form contains correct enctype:
<form ... enctype="multipart/form-data"> ... </form>
Sometimes happens that when someone upload multiples file, $_FILES return empty. This could happen when I select files that exceed some size. The problem can be in the POST_MAX_SIZE configuration.
On
app/code/core/mage/captcha/model/observer.php
change

Your issue is:
"Captcha Observer throws an error if login in RSS feed" issue #208
or if you wish you could only replace the variable $login to be like this:
$login = array_key_exists('username', array($loginParams)) ? $loginParams['username'] : null;
You may try out below points.
Use Magento Varien File Uploaded Classes to Upload the files.
Magento File Uploader
1) Check enctype="multipart/form-data" in your form.
2) Use Magento Form Key in your form.
3) Use Varien file uploader to upload your files using below links answers.

jQuery File Upload 'undefined' image url

I'm using a plugin called jQuery file upload to upload images to a page. Currently it uploads with the original image name as the file name (IMG_1234). I need a specific format for the image name on the server (eg 1.123456.jpg)
I found this PHP code that works for changing the image name:
class CustomUploadHandler extends UploadHandler
{
protected function trim_file_name($name, $type) {
$name = time()."_1";
$name = parent::trim_file_name($name, $type);
return $name;
}
}
When I upload an image, it is named correctly, but the link for the image preview is undefined. This prevents me from deleting the image via the plugin.
The variable data.url is undefined... If I go back to the original code that doesn't rename the image, everything works fine.
Has anyone had any experience with this plugin that could help? Thanks!
EDIT:
I've found part of the problem at least...the function to return the download link (which is also used for deletion) is giving the original file name, not the updated one. I am really new to PHP classes, so I'm not sure where the variable originates and how to fix it. I'd really appreciate any help I can get!
Here's the PHP code for that function:
protected function get_download_url($file_name, $version = null, $direct = false) {
if (!$direct && $this->options['download_via_php']) {
$url = $this->options['script_url']
.$this->get_query_separator($this->options['script_url'])
.'file='.rawurlencode($file_name);
// The `$file_name` variable is the original image name (`IMG_1234`), and not the renamed file.
if ($version) {
$url .= '&version='.rawurlencode($version);
}
return $url.'&download=1';
}
if (empty($version)) {
$version_path = '';
} else {
$version_url = #$this->options['image_versions'][$version]['upload_url'];
if ($version_url) {
return $version_url.$this->get_user_path().rawurlencode($file_name);
}
$version_path = rawurlencode($version).'/';
}
return $this->options['upload_url'].$this->get_user_path()
.$version_path.rawurlencode($file_name);
}
EDIT 2: I think it has something to do with 'param_name' => 'files', in the options. Anyone know what that does?
Fixed it by editing the trim_file_name function inside UploadHandler.php instead of extending the class in index.php.

Codeigniter -> File Upload Path | Folder Create

Currently I have the following:
$config['upload_path'] = 'this/path/location/';
What I would like to do is create the following controller but I am not sure how to attack it!!
$data['folderName'] = $this->model->functionName()->tableName;
$config['upload_path'] = 'this/'.$folderName.'/';
How would I create the $folderName? dictionary on the sever?
Jamie:
Could I do the following?
if(!file_exists($folderName))
{
$folder = mkdir('/location/'$folderName);
return $folder;
}
else
{
$config['upload_path'] = $folder;
}
am not sure what they are talking about by using the file_exist function since you need to check if its the directory ..
$folderName = $this->model->functionName()->tableName;
$config['upload_path'] = "this/$folderName/";
if(!is_dir($folderName))
{
mkdir($folderName,0777);
}
please note that :
i have added the permission to the folder so that you can upload files to it.
i have removed the else since its not useful here ( as #mischa noted )..
This is not correct:
if(!file_exists($folderName))
{
mkdir($folderName);
}
else
{
// Carry on with upload
}
Nothing will be uploaded if the folder does not exist! You have to get rid of the else clause.
$path = "this/$folderName/";
if(!file_exists($path))
{
mkdir($path);
}
// Carry on with upload
$config['upload_path'] = $path;
Not quite sure what you mean by 'dictionary', but if you're asking about how to create a variable:
$folderName = $this->model->functionName()->tableName;
$config['upload_path'] = "this/$folderName/";
To add/check the existence of a directory:
if(!file_exists($folderName))
{
mkdir($folderName);
}
else
{
// Carry on with upload
}
Not 100% sure what you want from your description so here are a few suggestions:
If you need to programmatically create a folder using PHP you can use the mkdir() function, see: http://php.net/manual/en/function.mkdir.php
Also, check out the Codeignitor file helper for reading and writing files:
http://codeigniter.com/user_guide/helpers/file_helper.html
If the folder already exists, you need to make sure the permissions are write-able. On windows you can right click on the folder, properties, security and edit there. On Linux you'll want the chmod command.
