swfupload limit the number of uploaded files - limit

Is there anyway to limit the number of uploaded files in swfupload ?
If there is no such setting in swfupload how can I check that number ?
Thanks

You can restrict the number of uploaded files using 'file_upload_limit' property in the setting object. eg:
var swfu = new SWFUpload({
upload_url : "http://www.swfupload.org/upload.php",
flash_url : "http://www.swfupload.org/swfupload.swf",
file_upload_limit: "10" // limit uploads to 10 files
});
You can use setFileUploadLimit(file_upload_limit) method to dynamically modify this setting.

Where can I access serverId?

I'd like to retrieve the serverId of an uploaded file. I tried to retrieve it in onupdatefiles, since it has a parameter which is fileitems. I assumed that I could use fileItems[0].serverId to fetch the uploaded file's servierId, but it showed null.
Who knows where am I wrong?
Sadly the event FilePond:updatefiles is called before files are (successfully) uploaded. Thus the file object has a the serverId null.
I had a similar issue and I worked around that with the following code:
document.addEventListener('FilePond:processfile', e => {
global.newFileIds = global.filePond.getFiles().map(x => x.serverId)
})
document.addEventListener('FilePond:removefile', e => {
global.newFileIds = global.filePond.getFiles().map(x => x.serverId)
})
FYI
FilePond:updatefiles is called when new files are added to the upload queue . In my case this was called too early (and twice).
FilePond:processfile is called after a file is successfully uploaded
FilePond:removefile is called when a file is removed but does not have a serverId ever (this is by design !?)

Corrupted PDF When Saving to Database over 50kB

I have a webpage where the user can upload a PDF file and send it using AJAX to my Flask application. Here is the ajax code:
var formData = new FormData();
formData.append('attachment', document.getElementById("attachment").files[0]);
$.ajax({
type: 'POST',
url: 'process_award_storage',
contentType: false,
processData: false,
data: formData
})
I do not think that this has any problems because I can print out the content and title of file in the python code. Then my flask model is defined as such, using LargeBinary for the PDF attachment:
class AwardStore(db.Model):
__tablename__ = 'awards_store'
id = db.Column(db.Integer, primary_key=True)
...
file = db.Column(db.LargeBinary, nullable=True) #I am sure this is the right file type for PDF saving
Lastly, here is how the AJAX file is saved to the database:
award = AwardStore(name=name, file=request.files['attachment'].read())
db.session.add(award)
db.session.commit()
I can see using my MySQL Workbench that it is saved. However, when I try to download the BLOB from there to the Desktop and open it, it says "Failed to load PDF document". The same happens when I use flask's send_file. It seems like I did everything as I saw online, but something is wrong.
Maybe these warnings are related?:
C:\Users\msolonko\Desktop\NICKFI~1\CACHTM~1\APP_DE~1\virt\lib\site-packages\pymysql\cursors.py:170: Warning: (1300, "Invalid utf8 character string: 'C4E5F2'")
result = self._query(query)
C:\Users\msolonko\Desktop\NICKFI~1\CACHTM~1\APP_DE~1\virt\lib\site-packages\pymysql\cursors.py:170: Warning: (1265, "Data truncated for column 'file' at row 1")
result = self._query(query)
I tried googling them and did not find anything. I appreciate any assistance.
EDIT:
I noticed that small files are typically uploaded and displayed properly. The issue is with files with sizes > ~50kB. The database I am using the AWS RDS, Is there a setting I can change somewhere to enable greater sizes?
The LargeBinary accepts a length field also.
which converts to mysql's BLOB whose default length is 65535 bytes (64kb).
Try increasing the length and set it to
a MEDIUMBLOB for 16777215 bytes (16 MB)
a LONGBLOB for 4294967295 bytes (4 GB).
Hope this will help

How do I set the individual upload file names?

I have a Laravel 5.3 app that has a form which users can upload multiple files using multiple file fields. The form work in that the files can be uploaded and moed to the destinationPath as I expect but I can't seem to change each of the files 'filename' values. It keeps saving the filename value as the php**.tmp.
Here is the foreach in my controller;
$files = $request->files;
foreach($files as $file){
$destinationPath = 'images/forms'; // upload path
$filename = $file->getClientOriginalName(); // get image name
$file->move($destinationPath, $filename); // uploading file to given path
$file->filename = $filename;
}
If I dd($filename) and dd($file->filename) within the foreach I do get the value (original name) I am looking for but if I dd($files) outside that foreach, the filename is set as the temp php value.
What am I missing? Thanks.
EDIT
The file object looks like this;
-test: false
-originalName: "sample_header_1280.png"
-mimeType: "image/png"
-size: 51038
-error: 0
path: "C:\xampp\tmp"
filename: "php7240.tmp"
basename: "php7240.tmp"
pathname: "C:\xampp\tmp\php7240.tmp"
extension: "tmp"
realPath: "C:\xampp\tmp\php7240.tmp"
I am trying to save the originalName to the db but it seems to default to saving the filename.
Turns out using a foreach for Input::file is not he approach here. If uploading multiple files from the same field - then you'd use a foreach to loop, move and save.
To upload files from multiple file inputs on the same form all you need to do is treat each input individually - as you might with any other form.
In my example I did this in my controller;
$data['image1'] = Input::file('image1')->getClientOriginalName();
Input::file('image1')->move($destinationPath, $data['image1']);
$data['image2'] = Input::file('image2')->getClientOriginalName();
Input::file('image2')->move($destinationPath, $data['image2']);
Not sure this is the best approach (there's always another way) but it worked for me.

Importing binary data to parse.com

I'm trying to import data to parse.com so I can test my application (I'm new to parse and I've never used json before).
Can you please give me an example of a json file that I can use to import binary files (images) ?
NB : I'm trying to upload my data in bulk directry from the Data Browser. Here is a screencap : i.stack.imgur.com/bw9b4.png
In parse docs i think 2 sections could help you out depend on whether you want to use REST api of the android sdk.
rest api - see section on POST, uploading files that can be upload to parse using REST POST.
SDk - see section on "files"
code for Rest includes following:
use some HttpClient implementation having "ByteArrayEntity" class or something
Map your image to bytearrayEntity and POST it with the correct headers for Mime/Type in httpclient...
case POST:
HttpPost httpPost = new HttpPost(url); //urlends "audio OR "pic"
httpPost.setProtocolVersion(new ProtocolVersion("HTTP", 1,1));
httpPost.setConfig(this.config);
if ( mfile.canRead() ){
FileInputStream fis = new FileInputStream(mfile);
FileChannel fc = fis.getChannel(); // Get the file's size and then map it into memory
int sz = (int)fc.size();
MappedByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, sz);
data2 = new byte[bb.remaining()];
bb.get(data2);
ByteArrayEntity reqEntity = new ByteArrayEntity(data2);
httpPost.setEntity(reqEntity);
fis.close();
}
,,,
request.addHeader("Content-Type", "image/*") ;
pseudocode for post the runnable to execute the http request
The only binary data allowed to be loaded to parse.com are images. In other cases like files or streams .. etc the most suitable solution is to store a link to the binary data in another dedicated storage for such type of information.

Does anyone know what is the 32 character string before the product image filename in Magento?

I ask this question, since I am trying to get the images I have just copied from Domain A to work in Domain B, (which is using the same database).
http://DOMAIN_A/magento/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/b/0/b0041-1.jpg
I think knowing what the 32 character string is, which help me find a good explanation why the images are not being found in the front or backend of Magento after reinstall on DOMAIN B.
RE: Magento version 1.4.0.1
Here's the code that creates that filename path, found in Mage_Catalog_Model_Product_Image:
// build new filename (most important params)
$path = array(
Mage::getSingleton('catalog/product_media_config')->getBaseMediaPath(),
'cache',
Mage::app()->getStore()->getId(),
$path[] = $this->getDestinationSubdir()
);
if((!empty($this->_width)) || (!empty($this->_height)))
$path[] = "{$this->_width}x{$this->_height}";
// add misk params as a hash
$miscParams = array(
($this->_keepAspectRatio ? '' : 'non') . 'proportional',
($this->_keepFrame ? '' : 'no') . 'frame',
($this->_keepTransparency ? '' : 'no') . 'transparency',
($this->_constrainOnly ? 'do' : 'not') . 'constrainonly',
$this->_rgbToString($this->_backgroundColor),
'angle' . $this->_angle,
'quality' . $this->_quality
);
// if has watermark add watermark params to hash
if ($this->getWatermarkFile()) {
$miscParams[] = $this->getWatermarkFile();
$miscParams[] = $this->getWatermarkImageOpacity();
$miscParams[] = $this->getWatermarkPosition();
$miscParams[] = $this->getWatermarkWidth();
$miscParams[] = $this->getWatermarkHeigth();
}
$path[] = md5(implode('_', $miscParams));
// append prepared filename
$this->_newFile = implode('/', $path) . $file; // the $file contains heading slash
So, the hash is generated from the configuration info (aspect ratio, etc), as well as the watermark info. This information will not usually change. However, I do see that the path is partially generated from the store_id of the current store, so your trouble may be there.
Is there a reason you can't let Magento use its normal caching procedures for both stores? Since Magento checks the filesystem for the cached image, there shouldn't be a conflict.
Hope that helps!
Thanks,
Joe
Upon contemplation, are you just trying to get the catalog images to work in both domains? The non-cached version of the catalog images are at %magento%/media/catalog/product. Copy the directories from that location and your catalog images should work.
Moving over the cached images isn't going to go far, since they will be deleted next time you flush the Magento cache. So, having moved the images that are in /media/catalog/product, flush the Magento image cache. Make sure that the file permissions are correct for reading. Then, head into Mage_Catalog_Model_Product_Image and take a look at the following code (approx line 270):
if ($file) {
// add these for debugging
Mage::log($baseDir.$file);
Mage::log(file_exists($baseDir.$file));
Mage::log($this->checkMemory($baseDir.$file));
if ((!file_exists($baseDir . $file)) || !$this->_checkMemory($baseDir . $file)) {
$file = null;
}
}
Add a var_dump or Mage::log statement in there (depending on whether you have logging enabled), and verify that the path to the images is correct, and that you have enough memory for the operation. This is the code that will choose the default image for you if no image path exists. If you still can't get it, post the output of those three logging statements and we'll keep trying. :)
