I have below code to upload excel file provided by API in base64_encode format.
I would like to download that file and save in to file system.
public function import(Request $request) {
if ($request->getMethod() === 'POST') {
$data = json_decode($request->getContent(), TRUE);
$directory = 'public://import/';
// create directory if it does not exist
file_prepare_directory($directory, FILE_CREATE_DIRECTORY | FILE_MODIFY_PERMISSIONS);
$uri = $directory. $data['name'];
$files_data = preg_replace('#^data:application/\w+;base64,#i', '', $data['data']);
$file_data = base64_decode($files_data);
$file = file_save_data($file_data, $uri, FILE_EXISTS_RENAME);
echo $file->id();
}
}
It goes to below function and gives error, although I have created tmp folder on project root and given needed 777 permission.
/drupal/web/core/includes/file.inc
function file_unmanaged_save_data($data, $destination = NULL, $replace = FILE_EXISTS_RENAME) {
// Write the data to a temporary file.
$temp_name = drupal_tempnam('temporary://', 'file');
if (file_put_contents($temp_name, $data) === FALSE) {
\Drupal::messenger()->addError(t('The file could not be created.'));
return FALSE;
}
// Move the file to its final destination.
return file_unmanaged_move($temp_name, $destination, $replace);
}
What I am missing? It is not converting and saving file.
Usually this happen because of wrong temporary location and permission, what I suggest you is go to /admin/config/media/file-system and make sure you set Temporary Directory correctly. if its fine. check the permission of it. you need to set it writeable by webservice.
Fixed
On URL : domain.com/admin/config/media/file-system
Temporary directory -> Folder location and permission issue.

I'm struggling around with a simple PHP functionality: Creating a ZIP Archive with some files in.
The problem is, it does not create only one file called filename.zip but two files called filename.zip.a07600 and filename.zip.b07600. Pls. see the following screenshot:
The two files are perfect in size and I even can rename each of them to filename.zip and extract it without any problems.
Can anybody tell me what is going wrong???
function zipFilesAndDownload_Defect($archive_file_name, $archiveDir, $file_path = array(), $files_array = array()) {
// Archive File Name
$archive_file = $archiveDir."/".$archive_file_name;
// Time-to-live
$archiveTTL = 86400; // 1 day
// Delete old zip file
#unlink($archive_file);
// Create the object
$zip = new ZipArchive();
// Create the file and throw the error if unsuccessful
if ($zip->open($archive_file, ZIPARCHIVE::CREATE) !== TRUE) {
$response->res = "Cannot open '$archive_file'";
return $response;
}
// Add each file of $file_name array to archive
$i = 0;
foreach($files_array as $value){
$expl = explode("/", $value);
$file = $expl[(count($expl)-1)];
$path_file = $file_path[$i] . "/" . $file;
$size = round((filesize ($path_file) / 1024), 0);
if(file_exists($path_file)){
$zip->addFile($path_file, $file);
}
$i++;
}
$zip->close();
// Then send the headers to redirect to the ZIP file
header("HTTP/1.1 303 See Other"); // 303 is technically correct for this type of redirect
header("Location: $archive_file");
exit;
}
The code which calls the function is a file with a switch-case... it is called itself by an ajax-call:
case "zdl":
$files_array = array();
$file_path = array();
foreach ($dbh->query("select GUID, DIRECTORY, BASENAME, ELEMENTID from SMDMS where ELEMENTID = ".$osguid." and PROJECTID = ".$osproject.";") as $subrow) {
$archive_file_name = $subrow['ELEMENTID'].".zip";
$archiveDir = "../".$subrow['DIRECTORY'];
$files_array[] = $archiveDir.DIR_SEPARATOR.$subrow['BASENAME'];
$file_path[] = $archiveDir;
}
zipFilesAndDownload_Defect($archive_file_name, $archiveDir, $file_path, $files_array);
break;
One more code... I tried to rename the latest 123456.zip.a01234 file to 123456.zip and then unlink the old 123456.zip.a01234 (and all prior added .a01234 files) with this function:
function zip_file_exists($pathfile){
$arr = array();
$dir = dirname($pathfile);
$renamed = 0;
foreach(glob($pathfile.'.*') as $file) {
$path_parts = pathinfo($file);
$dirname = $path_parts['dirname'];
$basename = $path_parts['basename'];
$extension = $path_parts['extension'];
$filename = $path_parts['filename'];
if($renamed == 0){
$old_name = $file;
$new_name = str_replace(".".$extension, "", $file);
#copy($old_name, $new_name);
#unlink($old_name);
$renamed = 1;
//file_put_contents($dir."/test.txt", "old_name: ".$old_name." - new_name: ".$new_name." - dirname: ".$dirname." - basename: ".$basename." - extension: ".$extension." - filename: ".$filename." - test: ".$test);
}else{
#unlink($file);
}
}
}
In short: copy works, rename didn't work and "unlink"-doesn't work at all... I'm out of ideas now... :(
ONE MORE TRY: I placed the output of $zip->getStatusString() in a variable and wrote it to a log file... the log entry it produced is: Renaming temporary file failed: No such file or directory.
But as you can see in the graphic above the file 43051221.zip.a07200 is located in the directory where the zip-lib opens it temporarily.
Thank you in advance for your help!
So, after struggling around for days... It was so simple:
Actually I work ONLY on *nix Servers so in my scripts I created the folders dynamically with 0777 Perms. I didn't know that IIS doesn't accept this permissions format at all!
So I remoted to the server, right clicked on the folder Documents (the hierarchically most upper folder of all dynamically added files and folders) and gave full control to all users I found.
Now it works perfect!!! The only thing that would be interesting now is: is this dangerous of any reason???
Thanks for your good will answers...
My suspicion is that your script is hitting the PHP script timeout. PHP zip creates a temporary file to zip in to where the filename is yourfilename.zip.some_random_number. This file is renamed to yourfilename.zip when the zip file is closed. If the script times out it will probably just get left there.
Try reducing the number of files to zip, or increasing the script timeout with set_time_limit()
http://php.net/manual/en/function.set-time-limit.php
I am pulling my hair out over here. I have spent the last week trying to figure out why the ZipArchive extractTo method behaves differently on linux than on our test server (WAMP).
Below is the most basic example of the problem. I simply need to extract a zip that has the following structure:
my-zip-file.zip
-username01
--filename01.txt
-images.zip
--image01.png
-songs.zip
--song01.wav
-username02
--filename01.txt
-images.zip
--image01.png
-songs.zip
--song01.wav
The following code will extract the root zip file and keep the structure on my WAMP server. I do not need to worry about extracting the subfolders yet.
<?php
if(isset($_FILES["zip_file"]["name"])) {
$filename = $_FILES["zip_file"]["name"];
$source = $_FILES["zip_file"]["tmp_name"];
$errors = array();
$name = explode(".", $filename);
$continue = strtolower($name[1]) == 'zip' ? true : false;
if(!$continue) {
$errors[] = "The file you are trying to upload is not a .zip file. Please try again.";
}
$zip = new ZipArchive();
if($zip->open($source) === FALSE)
{
$errors[]= "Failed to open zip file.";
}
if(empty($errors))
{
$zip->extractTo("./uploads");
$zip->close();
$errors[] = "Zip file successfully extracted! <br />";
}
}
?>
The output from the script above on WAMP extracts it correctly (keeping the file structure).
When I run this on our live server the output looks like this:
--username01\filename01.txt
--username01\images.zip
--username01\songs.zip
--username02\filename01.txt
--username02\images.zip
--username02\songs.zip
I cannot figure out why it behaves differently on the live server. Any help will be GREATLY appreciated!
To fix the file paths you can iterate over all extracted files and move them.
Supposing inside your loop over all extracted files you have a variable $source containing the file path (e.g. username01\filename01.txt) you can do the following:
// Get a string with the correct file path
$target = str_replace('\\', '/', $source);
// Create the directory structure to hold the new file
$dir = dirname($target);
if (!is_dir($dir)) {
mkdir($dir, 0777, true);
}
// Move the file to the correct path.
rename($source, $target);
Edit
You should check for a backslash in the file name before executing the logic above. With the iterator, your code should look something like this:
// Assuming the same directory in your code sample.
$dir = new DirectoryIterator('./uploads');
foreach ($dir as $fileinfo) {
if (
$fileinfo->isFile()
&& strpos($fileinfo->getFilename(), '\\') !== false // Checking for a backslash
) {
$source = $fileinfo->getPathname();
// Do the magic, A.K.A. paste the code above
}
}
So I am using this script to upload a file to a directory and show it live.
<?php
function UploadImage($settings = false)
{
// Input allows you to change where your file is coming from so you can port this code easily
$inputname = (isset($settings['input']) && !empty($settings['input']))? $settings['input'] : "fileToUpload";
// Sets your document root for easy uploading reference
$root_dir = (isset($settings['root']) && !empty($settings['root']))? $settings['root'] : $_SERVER['DOCUMENT_ROOT'];
// Allows you to set a folder where your file will be dropped, good for porting elsewhere
$target_dir = (isset($settings['dir']) && !empty($settings['dir']))? $settings['dir'] : "/uploads/";
// Check the file is not empty (if you want to change the name of the file are uploading)
if(isset($settings['filename']) && !empty($settings['filename']))
$filename = $settings['filename'] . "sss";
// Use the default upload name
else
$filename = preg_replace('/[^a-zA-Z0-9\.\_\-]/',"",$_FILES[$inputname]["name"]);
// If empty name, just return false and end the process
if(empty($filename))
return false;
// Check if the upload spot is a real folder
if(!is_dir($root_dir.$target_dir))
// If not, create the folder recursively
mkdir($root_dir.$target_dir,0755,true);
// Create a root-based upload path
$target_file = $root_dir.$target_dir.$filename;
// If the file is uploaded successfully...
if(move_uploaded_file($_FILES[$inputname]["tmp_name"],$target_file)) {
// Save out all the stats of the upload
$stats['filename'] = $filename;
$stats['fullpath'] = $target_file;
$stats['localpath'] = $target_dir.$filename;
$stats['filesize'] = filesize($target_file);
// Return the stats
return $stats;
}
// Return false
return false;
}
?>
<?php
// Make sure the above function is included...
// Check file is uploaded
if(isset($_FILES["fileToUpload"]["name"]) && !empty($_FILES["fileToUpload"]["name"])) {
// Process and return results
$file = UploadImage();
// If success, show image
if($file != false) { ?>
<img src="<?php echo $file['localpath']; ?>" />
<?php
}
}
?>
The thing I am worried about is that if a person uploads a file with the same name as another person, it will overwrite it. How would I go along scraping the filename from the url and just adding a random string in place of the file name.
Explanation: When someone uploads a picture, it currently shows up as
www.example.com/%filename%.png.
I would like it to show up as
www.example.com/randomstring.png
to make it almost impossible for images to overwrite each other.
Thank you for the help,
A php noob
As contributed in the comments, I added a timestamp to the end of the filename like so:
if(isset($settings['filename']) && !empty($settings['filename']))
$filename = $settings['filename'] . "sss";
// Use the default upload name
else
$filename = preg_replace('/[^a-zA-Z0-9\.\_\-]/',"",$_FILES[$inputname]["name"]) . date('YmdHis');
Thank you for the help
I need to know if a folder exists before creating it, this is because I store pictures inside and I fear that the pictures are deleted if overwrite the folder.
The code I have to create a folder is as follows
$path = public_path().'/images';
File::makeDirectory($path, $mode = 0777, true, true);
how can I do it?
See: file_exists()
Usage:
if (!file_exists($path)) {
// path does not exist
}
In Laravel:
if(!File::exists($path)) {
// path does not exist
}
Note: In Laravel $path start from public folder, so if you want to check 'public/assets' folder the $path = 'assets'
With Laravel you can use:
$path = public_path().'/images';
File::isDirectory($path) or File::makeDirectory($path, 0777, true, true);
By the way, you can also put subfolders as argument in a Laravel path helper function, just like this:
$path = public_path('images/');
You can also call this method of File facade:
File::ensureDirectoryExists('/path/to/your/folder')
which creates a folder if it does not exist and if exists, then does nothing
In Laravel 5.x/6 you can do it with Storage Facade:
use Illuminate\Support\Facades\Storage;
$path = "path/to/folder/";
if(!Storage::exists($path)){
Storage::makeDirectory($path);
}
Way -1 :
if(!is_dir($backupLoc)) {
mkdir($backupLoc, 0755, true);
}
Way -2 :
if (!file_exists($backupLoc)) {
mkdir($backupLoc, 0755, true);
}
Way -3 :
if(!File::exists($backupLoc)) {
File::makeDirectory($backupLoc, 0755, true, true);
}
Do not forget to use use Illuminate\Support\Facades\File;
Way -4 :
if(!File::exists($backupLoc)) {
Storage::makeDirectory($backupLoc, 0755, true, true);
}
In this way you have to put the configuration first in config folder
filesystems.php . [Not recommended unless you are using external disks]
The recommended way is to use
if (!File::exists($path))
{
}
See the source code
If you look at the code, it's calling file_exists()
I normally create random folders inside the images for each file this helps a bit in encrypting urls and thus public will find it hardr to view your files by simply typing the url to your directory.
// Check if Logo is uploaded and file in random folder name -
if (Input::hasFile('whatever_logo'))
{
$destinationPath = 'uploads/images/' .str_random(8).'/';
$file = Input::file('whatever_logo');
$filename = $file->getClientOriginalName();
$file->move($destinationPath, $filename);
$savedPath = $destinationPath . $filename;
$this->whatever->logo = $savedPath;
$this->whatever->save();
}
// otherwise NULL the logo field in DB table.
else
{
$this->whatever->logo = NULL;
$this->whatever->save();
}
This is what works great for me
if(!File::exists($storageDir)){
File::makeDirectory($storageDir, 0755, true, true);
$img->save('Filename.'.png',90);
}
I'm a PHP novice and so looking for some advice on a PHP function i have created to use within a Wordpress installation.
As you can see from the code below, it runs when one of the admin's press 'Publish' on a pending post.
It takes a Zip file that has been uploaded by a user via Gravity Forms, then unzips ONLY .mp3 extensions. Re-zips and moves all the files to a new folder in our Amazon S3 directory.
The code is pieced together from my limited knowledge and some help along the way with questions on here.
So, here's what i ended up with:
add_action('pending_to_publish', 'unzip_to_s3');
function unzip_to_s3() {
global $post;
global $wpdb;
// Only run function if post is portfolio post type
if ('portfolio' == $post->post_type) {
// Set temp path
$temp_path = '../wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/tmp/';
// Get filename from Zip file
$file = get_post_meta($post->ID, 'file_url', true);
$zip_file = basename($file);
// Create full Zip file path
$zip_file_path = $temp_path.$zip_file;
// Generate unique name for temp sub_folder for unzipped files
$temp_unzip_folder = uniqid('temp_TMS_', true);
// Create full temp sub_folder path
$temp_unzip_path = $temp_path.$temp_unzip_folder;
// Make the new temp sub_folder for unzipped files
if (!mkdir($temp_unzip_path, 0755, true)) {
die('Error: Could not create path: '.$temp_unzip_path);
}
// Unzip files to temp unzip folder, ignoring anything that is not a .mp3 extension
$zip = new ZipArchive();
$filename = $zip_file_path;
if ($zip->open($filename)!==TRUE) {
exit("cannot open <$filename>\n");
}
for ($i=0; $i<$zip->numFiles;$i++) {
$info = $zip->statIndex($i);
$file = pathinfo($info['name']);
if(strtolower($file['extension']) == "mp3") {
file_put_contents($temp_unzip_path.'/'.basename($info['name']), $zip->getFromIndex($i));
} else {
$zip->deleteIndex($i);
}
}
$zip->close();
// Re-zip the unzipped mp3's and store new zip file in temp folder created earlier
$temp_unzip_path = $temp_unzip_path.'/';
$zip = new ZipArchive();
$dirArray = array();
$new_zip_file = $temp_unzip_path.$zip_file;
$new = $zip->open($new_zip_file, ZIPARCHIVE::CREATE);
if ($new === true) {
$handle = opendir($temp_unzip_path);
while (false !== ($entry = readdir($handle))) {
if(!in_array($entry,array('.','..')))
{
$dirArray[] = $entry;
$zip->addFile($temp_unzip_path.$entry,$entry);
}
}
closedir($handle);
} else {
echo 'Failed to create Zip';
}
$zip->close();
// Set Media bucket dir
$bucket_path = '../wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/mixtape2/';
// Generate unique name for sub_bucket
$sub_bucket = uniqid('TMS_', true);
// Create full sub_bucket path
$sub_bucket_path = $bucket_path.$sub_bucket;
// Make the new sub_bucket
if (!mkdir($sub_bucket_path, 0755, true)) {
die('Error: Could not create path: '.$sub_bucket_path);
}
// Move mp3's to new sub_bucket
// Get array of all source files
$files = scandir($temp_unzip_path);
// Identify directories
$source = $temp_unzip_path;
$destination = $sub_bucket_path.'/';
// Cycle through all source files
foreach ($files as $file) {
if (in_array($file, array(".",".."))) continue;
// if move files is successful delete the original temp folder
if (rename($source.$file, $destination.$file)) {
rmdir($temp_unzip_path);
}
}
// Delete original Zip file
unlink($temp_path.$zip_file);
// Update Custom field for new Zip file location
update_post_meta($post->ID, 'file_url', 'http://themixtapesite.com/wp-content/uploads/gravity_forms/1-9e5dc27086c8b2fd2e48678e1f54f98c/2013/02/mixtape2/'.$sub_bucket.'/'.$zip_file);
}
}
Whilst this function does work, we're dealing with large files and so it does take a while to process...
What is happening is when the admin presses publish it triggers this function but the page just sits there until it's finished this function and then will continue. This function can take upto around 5 minutes to run.
I'm looking to optimise this function (in terms of code) but also see if there's a way i can run this in the background so that the admin can carry on with other things and not have to sit there waiting around.
Any help appreciated.
You may want to try to WP cron and schedule the task at that point so that it runs in the background. Here is some resources for that. the basic concept would go something like this.
if ( ! wp_next_scheduled( 'pending_to_publish' ) ) {
wp_schedule_single_event($timestamp,'pending_to_publish');
}
add_action('pending_to_publish', 'unzip_to_s3');
