I want to use PHPOffice/PHPWord to generate a word file in Laravel 5.2. This is working great! Only thing is, I would like to stream the file. Or, when the user chooses to generate a word document, it automatically opens.
I looked inside the WriterInterface.php and the only function possible is the save function. Does anyone know how to implicate a stream or open function?
$objWriter->open('../public/uploads/helloWorld.docx');
Save the file to a temporary folder, then use the download function #laravel Docs

What I want to archive:
I want to write a feature test using phpunit in Laravel.
What does the controller I want to test do:
It accepts uploads of test records to store it into a database. Each record consists of two files (xml, yml) with the same file name. Both files have to be read and stored in the database. The uploaded files are never stored on the server, they are directly processes.
What I want to test:
Upload a record and check if the correct data is in the database and available over the API
Check if I get the correct error if one file (xml or yml) is missing
Check if I get the right error if the files are not a valid record
and so on ...
What is my current problem?
I would like to use a template for the xml and yml files and use Faker to generate fake data for this test. The reason: Why not? My understanding of testing is, that you should test as many cases as possible and if static data is enough why do we use Faker and Factory in the Unit tests for the database and so on?
When I look at Laravel: Testing File Uploads, they generate there testing files with UploadedFile::fake(). My understanding of those files is, that they are empty and you can't use a template or something like that, to fill it with useful data. Most solutions I found just kept real files in their project. Like this.
I could use blade for this, as shown here, but I'm not really sure if I should abuse blade like this.
I could fully generate the xml and yml files using Yaml and XMLReader/XMLWriter, but there is a lot of static text in those files and I only need to fill data into some specific points.
Questions:
So what is the best way to create such a fake file? Should I use blade or twig or some other templating engine? A small solution would be appreciated.
Or should I generate the full file by myself and why is this better?
Or is there no point in generating fake data and I should use static data instead?
Here is my current test function:
public function testFullRecordUpload() {
// Generate record files to upload
// TODO Use template files with faker, or something like that
$xml_file = UploadedFile::fake()->create('test_file.xml', $sizeInKilobytes = 566);
$yml_file = UploadedFile::fake()->create('test_file.yml', $sizeInKilobytes = 20);
// Send Files
$response = $this->json('POST', '/upload', [
'xml' => $xml_file,
'yml' => $yml_file
]);
// Check response
$response->assertOk();
// Check if the uploaded data is available over API
// TODO
}
I am trying to generate an archive on-the-fly in PHP and send it to the user immediately (without saving it). I figured that there would be no need to create a file on disk as the data I'm sending isn't persistent anyway, however, upon searching the web, I couldn't find out how. I also don't care about the file format.
So, the question is:
Is it possible to create and manipulate a file archive in memory within a php script without creating a tempfile along the way?
I had the same problem but finally found a somewhat obscure solution and decided to share it here.
I came accross the great zip.lib.php/unzip.lib.php scripts which come with phpmyadmin and are located in the "libraries" directory.
Using zip.lib.php worked as a charm for me:
require_once(LIBS_DIR . 'zip.lib.php');
...
//create the zip
$zip = new zipfile();
//add files to the zip, passing file contents, not actual files
$zip->addFile($file_content, $file_name);
...
//prepare the proper content type
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=my_archive.zip");
header("Content-Description: Files of an applicant");
//get the zip content and send it back to the browser
echo $zip->file();
This script allows downloading of a zip, without the need of having the files as real files or saving the zip itself as a file.
It is a shame that this functionality is not part of a more generic PHP library.
Here is a link to the zip.lib.php file from the phpmyadmin source:
https://github.com/phpmyadmin/phpmyadmin/blob/RELEASE_4_5_5_1/libraries/zip.lib.php
UPDATE:
Make sure you remove the following check from the beginning of zip.lib.php as otherwise the script just terminates:
if (! defined('PHPMYADMIN')) {
exit;
}
UPDATE:
This code is available on the CodeIgniter project as well:
https://github.com/patricksavalle/CodeIgniter/blob/439ac3a87a448ae6c2cbae0890c9f672efcae32d/system/helpers/zip_helper.php
what are you using to generate the archive? You might be able to use the stream php://temp or php://memory to read and write to/from the archive.
See http://php.net/manual/en/wrappers.php.php
Regarding your comment that php://temp works for you except when you close it, try keeping it open, flushing the output, then rewind it back to 0 and read it.
Look here for more examples: http://us.php.net/manual/en/function.tmpfile.php
Also research output buffering and capturing: http://us.php.net/manual/en/function.ob-start.php
You need to use ZipArchive::addFromString - if you use addFile() the file is not actually added until you go to close it. (Horrible bug IMHO, what if you are trying to move files into a zip and you delete them before you close the zip...)
The addFromString() method adds it to the archive immediately.
Is there really a performance issue here, or does it just offend your sense of rightness? A lot of processes write temporary files and delete them, and often they never hit the disk due to caching.
A tempfile is automatically deleted when closed. That's it's nature.
There are only two ways I can think of to create a zip file in memory and serve it and both are probably more trouble than they are worth.
use a ram disk.
modify the ziparchive class to add a method that does everything the close() method does, except actually close the file. (Or add a leave-open parameter to close()).
This might not even be possible depending on the underlying C libraries.
I want to rename input file to be uploaded before sending to laravel.
Basically, i found an another way to rename the file in laravel but in this question I want to rename the file before sending to laravel.
In my case, I'm using jquery upload file, and now I want the input file to be renamed before uploading it. I want to get the new file name that I used to insert in the hidden input text.
Is there any solution to solve this kind of matter?
By the way, thank you in advance! ^_^
Did you check this: File Docs
as per this doc you can do this as follow:
$request->file('photo')->move($destinationPath, $fileName);
where $fileName is an optional parameter that renames the file.
so you can use this like:
$fileName = str_random(30); // any random string
then pass this as above.
So this is simple to understand what i want to achieve. So i get links like theese:
http://rockdizfile.com/atfmzkm7236t
http://rockdizfile.com/xuj5oincoqmy
http://rockdizfile.com/pg8wg9ej3pou
So theese links are from one cloud storage site I want to make a php script that automates their downloading.
So I can't find which is the script or the thing these links download button starts and how can I start that so i can download it with php on my server?
Basically my idea is to download a lot of files but don't wanna do it manually so need automatic way of doing it. As far as I know I make a request which is the following 2 urls:
http://rockdizfile.com/pg8wg9ej3pou
http://wi32.rockdizfile.com/d/wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz/Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3
So the first url is executing the next one but here comes the tricky part as far as I tested that last string Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 is the file name we get when downloading so if you change it with for example somefile.mp3 it will download somefile.mp3 but with the same file content as http://wi32.rockdizfile.com/d/wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz/Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 so the data is hidden in this hash wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz or i think so. And now is the tricky part how to get this hash? we have almost everything we have the code for the url atfmzkm7236t the hash wsli6rbhfp4r2ge4t7cqeeztijrprelfiw4afvqg5iwspmvqabpkmgiz and the filename Desislava%20feat.%20Mandi%20&%20Ustata%20-%20Pusni%20go%20pak%20(CDRIP).mp3 There must be a way to download from this site without clicking so please help me kinda a hack this :)
you can use PHP's header function to force a file to download
header('Content-disposition: attachment; filename=index.php');
readfile('Link');
You should know that this will not give you the ability to download PHP files from external websites.
You can only use this if you got the direct link to a file
It's impossibly to tell you without the source code
e.g. sha1("Test Message") gives you 35ee8386410d41d14b3f779fc95f4695f4851682 but sha256("Vote this up") gives you 65e03c456bcc3d71dde6b28d441f5a933f6f0eaf6222e578612f2982759378ed
totally different... unless you're hidden function add's "65e03c456bcc3d71dde6b28dxxxxxxxxxxxxxxxxxxxxxxxxxx" (where xxxxxxxxxxxxxxxxxxxxxxxxxx is a bunch of numbers I can't be arsed to work out) to each hash...
then sha1("Test Message") gives you 65e03c456bcc3d71dde6b28d441f5a933f6f0eaf6222e578612f2982759378ed
The file is embedded into the swf player.
alert(jwplayer('mp3player').config.file);
Something like:
<?PHP echo file_get_contents($_GET["url"]); ?>
<script>
document.location=jwplayer('mp3player').config.file;
</script>
Though I've actually just noticed they change 5 digits of the URL on each page request, and the script above uses 2 page requests. One to get the URL and HTML source and another to try and download the file, meaning the URL has changed before the second request has started.
I'm generating a pdf file with html2fpdf.
$pdf = new HTML2FPDF();
$pdf->HTML2FPDF("P","mm","A4");
$pdf->AddPage();
$pdf->WriteHTML($html);
$pdf->output('sample.pdf');
This sample works great. But:
How do I delete the pdf after the output? I just want to have links in my tool, the users can download the pdf and after that it shoud be deleted on the server.
How can I 'clean up' after generating the pdf?
You can use PHP's file deletion function called unlink()
Call this function with the full path to the generated PDF file (or any file for that matter) and PHP will delete that file.
http://php.net/manual/en/function.unlink.php
You don't necessarily have to delete the file immediately after the user has downloaded it. You can just as easily place all the generated files in one central folder and have a cron job execute a more general clean up script simply removing the older files.
One method could be -
Scan the contents of the folder using scandir().
Iterate over its files in a foreach loop..
Inspect the creation time of each file using filemtime().
If the creation time was over hour ago, delete the file using unlink().
Because you are generating the PDF file yourself within your PHP code, I didn't mention the permissions consideration. Here would be a good place to mention that your PHP must have the correct file system permissions in order to perform any action on the file system. You are creating a PDF file so it's safe to assume that you have the correct permissions to make changes to the file system but if you plan on using this unlink() function in other scripts make sure that the files you are dealing with have the correct permissions set.
If you don't add the 'F' flag to the output function there will be no pdf files stored on the server at all:
$pdf->output('sample.pdf', 'F'); //stores PDF on server
In your case the script itself behaves like an actual pdf file. So, creating a link to the script is just like a link to the pdf, except that the PDF is created every time the script is requested. To tell the browser it's a PDF the content-type response header must be set to application/pdf:
content-type: application/pdf
This way the broser knows that it's a pdf even if the URL is ending in a .php. You can use rewrite engine to make it end in pdf or whatever else.
Sending the headers is done by the fpdf/tcpdf. In short: you don't have to do any cleanup, because no pdf file is stored on the server.
If you wonder what the name is for than, try saving the pdf file. The recommanded name when saving will be sample.pdf.
Reference:
PHP header() function, at the examples there is one for sending pdf
FPDF::Output()
TCPDF::Output()
