I'm using Laravel Excel 2.1.0 in a local project to write a row into an excel file.
This is my code:
$filePath = storage_path('myfile.xls');
$rows = \Excel::load($filePath, function($reader) {
$sheet = $reader->sheet(0);
$sheet->appendRow(
array(
'Hello'
)
);
});
Everything works and a new line was appended to my file.
Sometimes can happens the excel file is opened while user try to append a new line. In this case Laravel, rightly, show me this error:
fopen(mypath\myfile.xls): failed to open stream: Resource temporarily unavailable
How can I handle this error in order to skip the function and go on with my code without append the row?
I solved in this way:
$filePath = storage_path('myfile.xls');
$fp = #fopen($filePath, "r+");
if($fp) {
$rows = \Excel::load($filePath, function($reader) {
$sheet = $reader->sheet(0);
$sheet->appendRow(
array(
'Hello'
)
);
});
}

I have a problem when uploading a file. I have multiple files in the array, I am uploading these files two times in the same function for the first time I am checking pdf file version, and file dimensions this block of code works perfectly but in the second block of code I am again uploading these files for merging these files it gives me this error "The file "A4.pdf" was not uploaded due to an unknown error". When I remove the first block of code then the second block of code start working.I don't know where I did mistake, I have searched a lot but not found the answer.
This block of code checking pdf file version and dimensions.
$paper_size = array();
$del_files = array();
foreach ($files as $file) {
$filename = time().date('m-d-y').$file->getClientOriginalName();
$file->move(public_path().'/uploads/check_pdf_files/', $filename);
$version = $this->pdfVersion(public_path().'/uploads/check_pdf_files/'.$filename);
if($version > 1.5)
{
File::delete('public/uploads/check_pdf_files/'.$filename);
return Response::json(" Your PDF file version is greater than 1.4 which is not compatible with our system, Please make it lower version.", 400);
}
$get_paper_size = $this->get_pdf_dimensions('public/uploads/check_pdf_files/'.$filename);
$paper_size[] = $get_paper_size;
$del_files[] = $filename;
}
if(round($paper_size[0]['width']) != round($paper_size[1]['width']))
{
foreach ($del_files as $del)
{
File::delete('public/uploads/check_pdf_files/'.$del);
}
return Response::json(" Your Files dimensions is not matching please try with same dimensions.", 400);
}
This block of code using for merging the files.
$new_pdf_file = array();
foreach ($request->file as $merge_file)
{
$newFile_name = time().$merge_file->getClientOriginalName();
$merge_file->move('public/uploads/', $newFile_name);
$new_pdf_file[] = $newFile_name;
}
dd($new_pdf_file);
$pdf = new \LynX39\LaraPdfMerger\PdfManage;
foreach($new_pdf_file as $new)
{
$pdf->addPDF('public/uploads/dummy_uploads/'.$new, 'all');
}
$temp_name = time().$request->merge_name;
$pdf->merge('file',base_path(). '/public/uploads/' . Auth::user()->email . '/'.$temp_name.'.pdf', 'P');
foreach($new_pdf_file as $delete_new)
{
File::delete('public/uploads/dummy_uploads/'.$delete_new);
}
$user = DB::table('user_pdf_files')->insert([
'user_files' => $request->merge_name.'.pdf',
'filename' => $temp_name.'.pdf',
'type' => $request->type[0],
'user_id' => Auth::user()->id,
]);
Session::flash('success', 'Files Merged Successfully');
return Response::json('success', 200);`
You need the fully qualified path to where you want the files saved to. Anytime you are moving or copying a file, ensure that you are using public_path() with the relative path as a parameter. This function outputs the fully qualified path to the public folder. For example:
$merge_file->move(public_path('uploads'), $newFile_name);
This should be why the first code block is working vs. the second one. Not a very descriptive error, though!
I am performing SSH in Laravel whereby I connect to another server and download a file. I am using Laravel Collective https://laravelcollective.com/docs/5.4/ssh
So, the suggested way to do this is something like this
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path);
if($result) {
return $path;
} else {
return 401;
}
Now that successfully downloads the file and moves it to my local server. However, I am always returned 401 because $result seems to be Null.
I cant find much or getting the result back from the SSH. I have also tried
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path, function($line){
dd( $line.PHP_EOL);
});
But that never gets into the inner function.
Is there any way I can get the result back from the SSH? I just want to handle it properly if there is an error.
Thanks
Rather than rely on $result to give you true / false / error, you can check if the file was downloaded successfully in another way:
// download the file
$result = \SSH::into('scripts')->get('/srv/somelocation/'.$fileName, $path);
// see if downloaded file exists
if ( file_exists($path) ) {
return $path;
} else {
return 401;
}
u need to pass file name also like this in get and put method:
$fileName = "example.txt";
$get = \SSH::into('scripts')->get('/remote/somelocation/'.$fileName, base_path($fileName));
in set method
$set = \SSH::into('scripts')->set(base_path($fileName),'/remote/location/'.$fileName);
in list
$command = SSH::into('scripts')->run(['ls -lsa'],function($output) {
dd($output);
});
Have a problem while trying to queue mail that have attachment.
I can send an email without any problems without queue. Attachment is correct and can be opened. Problem appear when I try to queue that email. Excel generated by maatwebsite/excel lib
Error:
InvalidPayloadException in Queue.php line 89:
5
I found that this part of code throws this error:
...\vendor\laravel\framework\src\Illuminate\Queue\Queue.php
protected function createPayload($job, $data = '', $queue = null)
{
$payload = json_encode($this->createPayloadArray($job, $data, $queue));
if (JSON_ERROR_NONE !== json_last_error()) {
throw new InvalidPayloadException;
}
return $payload;
}
My code looks like:
excel = Excel::create('Report', function($excel) {
$excel->sheet('Sheetname', function($sheet) {
$sheet->fromArray([['aaa']]);
});
})->string('xlsx');
Mail::to('mail#mail.com')
->queue(new Report($excel));
I've tried to utf8_encode($excel) but then I cannot open mail attachment and I think that any operation on generated excel will corrupt file...
This problem also appear when I try to attach excel file from disk.
Any help?
I have been going round and round with this. I have uploads working with the follow:
public function store(Tool $tool)
{
If(Input::hasFile('file')){
$file = Input::file('file');
$name = $file->getClientOriginalName();
$path=Storage::put('public',$file); //Storage::disk('local')->put($name,$file,'public');
$file = new File;
$file->tool_id = $tool->id;
$file->file_name = $name;
$file->path_to_file = $path;
$file->name_on_disk = basename($path);
$file->user_name = \Auth::user()->name;
$file->save();
return back();
}
however when I try to download with:
public function show($filename)
{
$url = Storage::disk('public')->url($filename);
///$file = Storage::disk('public')->get($filename);
return response()->download($url);
}
I get the FileNotFound exception from laravel
However, if I use this instead:
$file = Storage::disk('public')->get($filename);
return response()->download($file);
I get
FileNotFoundException in File.php line 37: The file "use calib;
insert into
notes(tool_id,user_id,note,created_at,updated_at)
VALUES(1,1,'windows server 2008 sucks',now(),now());" does not exist
which is the actual content of the file...
It can obviously find the file. but why wont it download?
Try this:
return response()->download(storage_path("app/public/{$filename}"));
Replace:
$file = Storage::disk('public')->get($filename);
return response()->download($file);
With:
return response()->download(storage_path('app/public/' . $filename));
response()->download() takes a path to a file, not a file content. More information here: https://laravel.com/docs/5.4/responses#file-downloads
If any one still could not find their file even though the file clearly exists then try
return response()->file(storage_path('/app/' . $filename, $headers));
It could be due to a missing directory separator or it isn't stored inside the public folder.
I am trying to upload multiple files but I only get 1 file in return.Below is my code:
public function uploadQuoteItemImage(){
$file=Input::file('filename');
$file_count=count($file);
dd($file_count);
$uploadcount=0;
foreach($file as $f){
$random_name=str_random(8);
$destinationPath='images/';
$extension=$file->getClientOriginalExtension();
$filename=$random_name.'_quote_itm_image.'.$extension;
$byte=File::size($file); //get size of file
$uploadSuccess=Input::file('filename')->move($destinationPath,$filename);
$uploadcount ++;
}
if ($uploadcount == $file_count){
QuoteItemImage::create(array(
'quote_item_id'=>Input::get('quote_item_id'),
'filename'=>$filename,
'filesize'=>$byte
));
return Common::getJsonResponse(true, 'image created', 200);
}
}
Even though I sent 3 files its returning only 1 file. Please help.
so in the form-data of postman you are giving the key attribute as filename for files
in turn it should be filename[] since you are sending array of data
once you set it it works fine .
now you can check in the php code like below
$files = Input::file('filename');
foreach ($files as $one) {
$filename = $one->getClientOriginalName();
$listfilenames[] = $filename;
}
echo $listfilenames
