FMElfinderBundle 5 - how to set temp folder for upload - symfony

Question

I am using FMElfinderBundle v.5 (for some reasons I cannot use latest version) with Symfony 2.8.12. I followed documentation and it worked fine, until there was request to allow upload large files (up to 20MB). I changed upload_max_size parameter to 20M and it was ok, but during upload files are split to 2MB chunks and elfinder tries to store them in temp directory. Problem is, that it has no access there. It does not read settings from virtual host definition, it always uses system temp folder.
Reading documentation I have found that there can be used two parameters for configuring elfinder temp dir - upload_temp_path and common_temp_path. But i didn't have luck with setting them. Every time I run in PHPStorm console command s cache: clear --no-warmup I get InvalidConfigurationException.
I tried to put parameters somewhere else in config structure under fm_elfinder key, but still the same exception.
This is my configuration in config.yml:
fm_elfinder:
instances:
default:
locale: %locale%
editor: ckeditor
fullscreen: true
theme: smoothness
include_assets: true
relative_path: false
connector:
roots:
uploads:
driver: LocalFileSystem
path: uploads
upload_max_size: 20M
Anyone please can help me, how to set temp dir?

Answer 1

Ok, some detailed info:
I took ElFinderConfigurationReader from ElFinder bundle and saved it into my project under name ElFinderConfigurationCustomReader. Then this class i defined as a service:
service.custom_fm_elfinder.configurator:
class: CSBN\SVJBundle\Component\ElFinder\ElFinderConfigurationCustomReader
arguments: ['%fm_elfinder%', '#request_stack', '#service_container', '%elfinder_temporary_path%']
variable elfinder_temporary_path is set in parameters.yml.
in config.yml i set my own configuration reader:
fm_elfinder:
configuration_provider: service.custom_fm_elfinder.configurator
And in my newly created file ElFinderConfigurationCustomReader i just in method getConfiguration added one row:
$options['uploadTempPath'] = $this->temporaryPath;
which is taken from service parameters in constructor.
Hope this helps you.
Edit: full function copy:
/**
* #param $instance
*
* #return array
*/
public function getConfiguration($instance)
{
$request = $this->requestStack->getCurrentRequest();
$efParameters = $this->parameters;
$parameters = $efParameters['instances'][$instance];
$options = array();
$options['corsSupport'] = $parameters['cors_support'];
$options['debug'] = $parameters['connector']['debug'];
$options['bind'] = $parameters['connector']['binds'];
$options['plugins'] = $parameters['connector']['plugins'];
$options['uploadTempPath'] = $this->temporaryPath;
$options['roots'] = array();
foreach ($parameters['connector']['roots'] as $parameter) {
$path = $parameter['path'];
$homeFolder = $request->attributes->get('homeFolder');
if ($homeFolder !== '') {
$homeFolder = '/'.$homeFolder.'/';
}
$driver = $this->container->has($parameter['driver']) ? $this->container->get($parameter['driver']) : null;
$driverOptions = array(
'driver' => $parameter['driver'],
'service' => $driver,
'glideURL' => $parameter['glide_url'],
'glideKey' => $parameter['glide_key'],
'plugin' => $parameter['plugins'],
'path' => $path.$homeFolder, //removed slash for Flysystem compatibility

'URL' => $this->getURL($parameter, $request, $homeFolder, $path),
'alias' => $parameter['alias'],

'copyTo' => $parameter['copy_to'],
'uploadOverwrite' => $parameter['upload_overwrite'],
'uploadAllow' => $parameter['upload_allow'],

'separator' => $parameter['separator'],
'timeFormat' => $parameter['time_format'],
'archiveMimes' => $parameter['archive_mimes'],
'archivers' => $parameter['archivers'],
);
if ($parameter['volume_id'] > 0) {
$driverOptions['id'] = $parameter['volume_id'];
}
if (!$parameter['show_hidden']) {
$driverOptions['accessControl'] = array($this, 'access');
};
$options['roots'][] = array_merge($driverOptions, $this->configureDriver($parameter));
}
return $options;
}

Answer 2

Ok, i have found solution. It is necessary to make yoour own custom configuration reader and replace the original one. Configuration class must implement ElFinderConfigurationProviderInterface. See [https://github.com/helios-ag/FMElfinderBundle/blob/master/Resources/doc/advanced-configuration.md#custom-configuration-provider][1] for more details.
