Usage
--------------
* Must use 'forceChunkSize=true' on client side.
* Chunk preprocessor not supported.
* One should ensure indices on the gridfs collection on the property 'flowIdentifier'.
Besides the points above, the usage is analogous to the 'normal' flow-php:
```php
$config = new \Flow\Mongo\MongoConfig($yourGridFs);
$file = new \Flow\Mongo\MongoFile($config);
if ($_SERVER['REQUEST_METHOD'] === 'GET') {
if ($file->checkChunk()) {
header("HTTP/1.1 200 Ok");
} else {
header("HTTP/1.1 204 No Content");
return ;
}
} else {
if ($file->validateChunk()) {
$file->saveChunk();
} else {
// error, invalid chunk upload request, retry
header("HTTP/1.1 400 Bad Request");
return ;
}
}
if ($file->validateFile()) {
// File upload was completed
$id = $file->saveToGridFs(['your metadata'=>'value']);
if($id) {
//do custom post processing here, $id is the MongoId of the gridfs file
}
} else {
// This is not a final chunk, continue to upload
}
```
Delete unfinished files
-----------------------
For this you should setup cron, which would check each chunk upload time.
If chunk is uploaded long time ago, then chunk should be deleted.
Helper method for checking this:
```php
\Flow\Mongo\MongoUploader::pruneChunks($yourGridFs);
```
