I uploaded this excel file: myExceldocument.xlsx
After uploading I want to store in a folder.
I used this method:
$uploadedFile = $request->file('files')[0]->getClientOriginalName(); //it worked
Excel::store(new DeductionsImport, $uploadedFile, 'documents');
'documents' is related to filesystem.
The excel file is correctly filed in my folder called 'documents'.
The problem is when I open it, the excel file is empty!
Do you know why ?
My goal is only upload an excel document and store in folder.
Excel::store is for storing exports, not saving uploaded files.
If you are simply trying to save your myExceldocument.xlsx to your documents folder, the request object has a simple method for it.
// Where 'files' is the name of the upload field in HTML.
$request->file('files')->store('documents');
Another example:
$fileNameToStore = $request->file('files')[0]
Storage::disk('documents')->put($fileNameToStore, fopen($file, 'r+'));
work but is not the best solution because folder is filed with '' :
$file->storeAs('',$file->getClientOriginalName(),'documents');

I am allowing users to upload any kind of file on my page, but there might be a clash in names of files. So, I want to rename the file automatically, so that anytime any file gets uploaded, in the database and in the folder after upload, the name of the file gets changed also when other user downloads the same file, renamed file will get downloaded.
I tried:
if (Input::hasFile('file')){
echo "Uploaded</br>";
$file = Input::file('file');
$file ->move('uploads');
$fileName = Input::get('rename_to');
}
But, the name gets changed to something like:
php5DEB.php
phpCFEC.php
What can I do to maintain the file in the same type and format and just change its name?
I also want to know how can I show the recently uploaded file on the page and make other users download it??
For unique file Name saving
In 5.3 (best for me because use md5_file hashname in Illuminate\Http\UploadedFile):
public function saveFile(Request $request) {
$file = $request->file('your_input_name')->store('your_path','your_disk');
}
In 5.4 (use not unique Str::random(40) hashname in Illuminate\Http\UploadedFile). I Use this code to ensure unique name:
public function saveFile(Request $request) {
$md5Name = md5_file($request->file('your_input_name')->getRealPath());
$guessExtension = $request->file('your_input_name')->guessExtension();
$file = $request->file('your_input_name')->storeAs('your_path', $md5Name.'.'.$guessExtension ,'your_disk');
}
Use this one
$file->move($destinationPath, $fileName);
You can use php core function rename(oldname,newName) http://php.net/manual/en/function.rename.php

file uploads 101
Everything you need to know about file upload is there.
-- Edit --
I modified my answer as below after valuable input from #cpburnz and #Moinuddin Quadri. Thanks guys.
First your storage driver should look like this in /your-app/config/filesystems.php
'public' => [
'driver' => 'local',
'root' => storage_path('app/public'), // hence /your-app/storage/app/public
'visibility' => 'public',
],
You can use other file drivers like s3 but for my example I'm working on local driver.
In your Controller you do the following.
$file = request()->file('file'); // Get the file from request
$yourModel->create([
'file' => $file->store('my_files', 'public'),
]);
Your file get uploaded to /your-app/storage/app/public/my_files/ and you can access the uploaded file like
asset('storage/'.$yourModel->image)
Make sure you do
php artisan storage:link
to generate a simlink in your /your-app/public/ that points to /your-app/storage/app/public so you could access your files publicly. More info on filesystem - the public disk.
By this approach you could persists the same file name as that is uploaded. And the great thing is Laravel generates an unique name for the file so there could be no duplicates.
To answer the second part of your question that is to show recently uploaded files, as you persist a reference for the file in the database, you could access them by your database record and make it ->orderBy('id', 'DESC');. You could use whatever your logic is and order by descending order.
You can rename your uploaded file as you want . you can use either move or storeAs method with appropiate param.
$destinationPath = 'uploads';
$file = $request->file('product_image');
foreach($file as $singleFile){
$original_name = strtolower(trim($singleFile->getClientOriginalName()));
$file_name = time().rand(100,999).$original_name;
// use one of following
// $singleFile->move($destinationPath,$file_name); public folder
// $singleFile->storeAs('product',$file_name); storage folder
$fileArray[] = $file_name;
}
print_r($fileArray);
correct usage.
$fileName = Input::get('rename_to');
Input::file('photo')->move($destinationPath, $fileName);
at the top after namespace
use Storage;
Just do something like this ....
// read files
$excel = $request->file('file');
// rename file
$excelName = time().$excel->getClientOriginalName();
// rename to anything
$excelName = substr($excelName, strpos($excelName, '.c'));
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;
$excel->move(public_path('equities'),$excelName);
This guy collect the extension only:
$excelName = substr($excelName, strpos($excelName, '.c'));
This guy rename its:
$excelName = 'Catss_NSE_'.date("M_D_Y_h:i_a_").$excelName;
I would like to rename a collection of uploaded files, but when I use addAllMediaFromRequest() I can't retrieve information from the files.
In this example; I need to know the file extension in order to rename the file.
$files = $post->addAllMediaFromRequest();
$files->each(function (FileAdder $file) {
$file->usingFileName(Str::random(16) . '.jpg') // What if it's a png?
->toMediaCollection();
});
To get a file extension within laravel:
$request->file('photo')->extension()
To create new file name:
$newFileName = Str::random(20) .'.'.$request->file('photo')->extension();
don't forget to import Str class.
then you could rename the uploaded file before storing it easily
$item->addMedia($request->photo)->usingFileName($newFileName)->toMediaCollection('photo');
code tested Laravel v9
I have a upload form and also a Dropzone file uploader beside it where users can upload their .csv files .
I want to check whether the file is new or not.
the check should contain if the contents of file are new or not
I store the file names in database for checking new files, but the problem is when the user rename the same file and upload it again.
My solution is hashing the content of each file and store it beside its name in database.
but I don't know how to hash content of .csv file in php , Laravel.
I've tried using
hash_file('md5' , Request::file('myFileName')->getClientOriginalName());
but it results in file or stream not found.
What is the correct way of checking the new file regardless of its name?
Thanks in advance.
Calculating hash of a file is a correct way to go.
Do something like this:
public function uploadFile() {
// check if upload is valid file (example: request()->file('myFileName')->isValid() )
// calculate hash of a file
$fileHash = sha1_file( request()->file('myFileName')->path() );
//search for file in database and block same file upload (Files is Elequent model)
if( Files::where('hash', $fileHash)->firstOrNull() != null) {
abort(400); // abort upload
}
// do something with file and save hash to DB
}
My purpose is uploading a remote file create from my PC to specific folder, but I don't know whats wrong with my code below. It uploads the file with the name and the .jpg extension, but it is not moving the file to the specified folder.
if(isset($_POST["image"])){
define("SITE_NAME","project_name/"); //constant for project name
define("SITE_PATH",$_SERVER['DOCUMENT_ROOT']."/".SITE_NAME); //constant for project base directory
define("IMAGES_URL",SITE_URL."images/"); //constant for image directory
$upload_base_dir=IMAGES_URL;
$upload_time_dir=date('Y')."/".date('m')."/".date('d')."/"; // setup directory name
$upload_dir = $upload_base_dir.$upload_time_dir;
if (!file_exists($upload_dir)) {
mkdir($upload_dir, 0777, true); //create directory if not exist
}
$input = $_POST["image"];
$file = fopen(time()."image.jpg", 'wb');
fwrite($file, $input);
//$image_name=basename($_FILES['image']['name']);
$image=time().'_'.$image_name;
move_uploaded_file($file,$upload_dir.$image);
fclose($file);
}
Any suggestions? Thank you in advance.
move_uploaded_file($file,$upload_dir.$image) will only work for items within temp, that are accessable via $_FILES superglobal. If you are sending your file as a strieam within post, that wont work.
1) If file is a form upload make sure form is a multipart and access your file via $_FILES superglobal
move_uploaded_file($_FILES['userfile']['tmp_name'], $yourDirectory.$yourFilename);
2) If you post the file as a stream via post (keep in mind this will only work for small files as large ones will exceed request limit). Save the file directly to it's destiantion using fopen or to move it after you created it use rename() - http://php.net/manual/en/function.rename.php
rename($currentFilePath, $newFilePath)
P.S. sending files as post streams is a very very bad idea.
I have a problem with saving PDF files to folders on my server. The code worked at one time and now it doesn't. What I want it to do is to check if someone is trying to upload a PDF when a form is submitted, and if there is a PDF in the file field it uploads it and then saves the path to the mysql database. Code is below:
if (!empty($_FILES['pdf'])){
$idir = "../files/PDF/"; //my directory file is supposed to be saved in
$randomd=rand(0000000,9999999); //creates a random number as filename
$domain = "http://".$_SERVER['HTTP_HOST'];
$file_ext = strrchr($_FILES['pdf']['name'], '.'); grabs file extension. my code checked if the file was a pdf a different way and neither seems to work.
$destination=$randomd.$file_ext; //new filename
if ($file_ext=='pdf') {
move_uploaded_file($_FILES['pdf']['tmp_name'], "$idir" . $destination);
$pdf= $domain."/files/PDF/".$destination; } else { echo("File type not supported.");
mysql_query("UPDATE tbl_listings SET pdf='$pdf' WHERE listing_id='$lid'");
}
The if not empty does not work and it always tries to upload a file, but when I check the folder nothing is in there and it doesnt update the mysql.
$_FILES['pdf'] will never be empty(when the form has been submitted), no matter if a file has been selected or not, it will always return an array.
Check $_FILES['pdf']['error'] , it will be 4 when no file has been uploaded.
