How to use the flow-php-server

[tombujok]

Hi,

Is there a small example available how to use the flow-php-server from scratch?

Thanks
Tom

+1 for example plz

[AidasK]

Basic usage example at readme.md is almost complete, just put it to php file:

index.php:

if (\Flow\Basic::save('./final_file_destination', './chunks_temp_folder')) {
  // file saved successfully and can be accessed at './final_file_destination'
} else {
  // This is not a final chunk or request is invalid, continue to upload.
}

We can also improve it by providing our config class and request class:

index.php:

$config = new Config(array(
   'tempDir' => './chunks_temp_folder'
));
$request = new Request();
if (\Flow\Basic::save('./final_file_destination', $config, $request)) {
  // file saved successfully and can be accessed at './final_file_destination'
} else {
  // This is not a final chunk or request is invalid, continue to upload.
}

Now, we have access to flow.js request params, because we have created Request class.
Please look for available getters here: https://github.com/flowjs/flow-php-server/blob/master/src/Flow/Request.php

Our final index.php:

$config = new Config(array(
   'tempDir' => './chunks_temp_folder'
));
$request = new Request();
if (\Flow\Basic::save(__DIR__ . '/' . $request->getFileName(), $config, $request)) {
  echo "Hurray, file was saved in " . __DIR__ . '/' . $request->getFileName();
}
// In most cases, do nothing, \Flow\Basic handles all errors

For more detailed explanation, please look inside the source: https://github.com/flowjs/flow-php-server/blob/master/src/Flow/Basic.php

Flow.js configuration:

var flow = new Flow({
  target:'index.php'
});
flow.assignBrowse(document.getElementById('browseButton'));
flow.on('fileSuccess', function(file,message){
    console.log(file,message);
    alert("File was uploaded: " + message);
});
flow.on('filesSubmitted', function(file) {
   flow.upload();// instant upload
});

Thanks.
I am sorry, but I am new to PHP - how can I include/import the "flow-php-server" server code in the index.php cass.?
How should the folder structure look like?

Sorry, I can't teach you PHP, but I can give you some hints:

• Use composer - https://getcomposer.org/
  Composer should do all the nasty job of downloading packages and autoloading classes.
  Please google some composer tutorials.
• Or you can use flow autoloader: https://github.com/flowjs/flow-php-server/blob/master/src/Flow/Autoloader.php
  But I don't think this is a good idea. Use composer, it will do everything for you.

Hello,

I have exactly the same issue Tombujok, I see only classes but nothing that's instantiated, how to load these classes?

I tested:

<code
require_once('flow-php-server/src/Flow/Basic.php');
$config = new Config(array(
'tempDir' => './chunks_temp_folder'
));
$request = new Request();
if (\Flow\Basic::save('./final_file_destination', $config, $request)) {
// file saved successfully and can be accessed at './final_file_destination'
die(json_encode([
'success' => true,
'files' => $_FILES,
'get' => $_GET,
'post' => $_POST,

    ]));
} else {
    // This is not a final chunk or request is invalid, continue to upload.
    die(json_encode([
        'success' => false,
        'files'   => $_FILES,
        'get'     => $_GET,
        'post'    => $_POST,

    ]));
}

Return : Fatal error: Class 'Config' not found in /var/www/wamteam/PHP/controler.php on line 32

No, it's not about teaching PHP - it's about usability.

In the Java world we normally create a sample project that simply works -
you just take it and use it.
Code snippets are cool, but it's time consuming to put it all together-
and everybody does the same thing all the time...
It would be great to have a sample PHP project with the working service - I
could just grab it and copy to my Apache...

If you are using composer, then your index.php should start with:

<?php
// path to composer autoloader
require_once( __DIR__ . '/../vendor/autoload.php');
...

Without composer:

<?php
require_once(__DIR__ . '/../src/Flow/Autoloader.php');
Flow\Autoloader::register();
....

Hope this helps

[120dev]

Thanks works great after
composer install (path flow-php-server/)

and load autoload.php in vendor.

Thanks

Alright! Got this working with Laravel. There were some problems but I recreated the basic class and it's looking good.

Hello, I'm trying implementing this at YII Framework, but I have some problems because my application make a lot of GET and POST request to send chunks.

I understand that, but my question is.

why GET requests return a "404 not found"?

or even

how can I avoid the GET Requests to use just POST?

[ImanMh]

I'm also having an issue with using this library:

This is the first lines in my flow-php-server/src/index.php

<?php
    require_once( __DIR__ . '/../vendor/autoload.php');

but I'm getting this error:

Fatal error: Class 'Config' not found in /Users/Iman/Documents/experiments/flow.js/flow-php-server/src/index.php on line 4

should I use this at top of my index.php?

namespace Flow;

When I add the namespace, I get 404 and "Provisional headers are shown" errors in my browser network panel.

What am I missing?

[jesusp]

I solved the problem I had by doing the next steps:

1.- include the files and using the following namespaces:

require_once(dirname(FILE) . "/../extensions/vendors/Flow/Autoloader.php");
use Flow\Autoloader as FAutoloader;
use Flow\Config as FConfig;
use Flow\Request as FRequest;
use Flow\Basic as FBasic;

2.- instantiate config and Request:

 FAutoloader::register();
$config = new FConfig(['tempDir'=>$tmpDir]);
$request = new FRequest();

3.- call the Static function save in Basic passing the required parameters:

FBasic::save($fileName, $config, $request);

and finally in the JavaScript file I changed a property called testChunks which is normally "true" to "false", that's to avoid lots of GET requests!.

I hope those steps work for you!.

[ImanMh]

I solved my problem by copy pasting the source code of Node.js sample into my html file that I was using to select files to upload. I think I was making a mistake in my JavaScript.
Any way I think there would be awesome if there was a working samlpe of flow.js and flow-php-server integration available.

[batusa]

@jesusp thanks for the advice! it helped me to make flow.js work out on Yii.

[jesusp]

@batusa You're welcome it's always a great pleasure to contribute with comments!. I feel very well because that worked well for you!...

[ivigr]

my frontend seems to run well and pictures are uploaded, chrom console like below:

catchAll
["fileAdded", e, Event]
shop.js:98
catchAll
["filesAdded", Array[1], Event]
shop.js:98
catchAll
["filesSubmitted", Array[1], Event]
shop.js:98
catchAll ["uploadStart"] shop.js:98
catchAll
["fileProgress", e, f]
shop.js:98
catchAll ["progress"] shop.js:98
catchAll
["fileSuccess", e, "<script language='javascript' type='text/javascript'>window.location.href='user/#/login/0';</script>", f]
shop.js:98
catchAll ["complete"]

but in fact flow listeners are not called, console.log nothing. The code like this:

//flow event listener
var flow = new Flow({});
flow.on('fileSuccess', function(file,message){
console.log(file,message);
});
flow.on('filesSubmitted', function(file) {
console.log('filesSubmitted');
flow.upload();// instant upload
});

and nothing is happened in backend.

I am sorry to ask the same question again, Is there a full example available how to use the flow-php-server from scratch?

much appreciated.

help::
i used flow.js php server to upload a file and its working
the only problem i faced is the file is uploaded with out extension for example jpg
an image file was uploaded as
filenamejpg and the file is not opening.

[ofix]

Without any third-party php framework in my php server side, when using this library I also encountered the problem that Class 'Config' not found. I fixed it as following, may it would help.

require_once (DIR.'/../lib/flow-php-server/src/Flow/Autoloader.php');
Flow\Autoloader::register();
$config = new Flow\Config(array(
'tempDir' => DIR.'./../upload/chunks_temp_folder'
));
$file = new \Flow\File($config);

[muhammadyibr]

@jesusp having testChunks to false worked for me

Thanks

[aklassen]

@viruskst Do you already have an solution for your extension problem? I'm having similar issues here as well.

[muhammadyibr]

@aklassen do you have testChunks as false?

[vasimlook]

in PHP
