Rails 3: best way to preview image before upload
So! :) The main idea is to use the FileReader Javascript Class, which is really handy for what you need to do. You just have to listen to the "change" event on your file input and then call a method that will use the "readAsDataURL()" method of the FileReader class. Then you just have to fill the source of a "preview img tag" with the returned result of the method... I've wrote you a simple jsFiddle that achieves what you want. You can see my code below: <!-- HTML Code --> <div class="upload-preview"> <img /> </div> <input class="file" name="logo" type="file"> //JS File $(document).ready(function(){ var preview = $(".upload-preview img"); $(".file").change(function(event){ var input = $(event.currentTarget); var file = in

Does this PHP image upload code has any secure bugs(Image files on LNMP server had been malicious replaced)?
Yes, there are security bugs. The upload filename is controlled by the user: $filename = explode(".",$_FILES['upload_file']['name']); $ext = end($filename); the filename doesn't necessarily have to contain a dot, $ext will be the whole filename everyting after the last dot will end up in $ext In both cases $ext can be freely controlled by an attacker, and seen that you later use it in your sql query without sanitation, you have a serious sql injection vulnerability. You shouldn't build sql queries by concatenating strings. You're using PDO, so do yourself a favor and use parameterized queries, it will save you a lot of trouble. edit: Another vulnerability may be that your script allows you to upload any file type, so if you didn't disable execution of php for your upload directo

How do you upload image and set it as featured image on wordpress using C# metaweblog api?
I found the answer to the problem. XML-RPC alone cannot set any uploaded image to featured image. Head over to this issue page http://core.trac.wordpress.org/ticket/15098. The patch allows returning the ID information of the uploaded image when using wp.uploadFile/metaWeblog.newMediaObject. Once the image ID(not the image URL) is returned, you can set it to wp_post_thumbnail and it should appear as featured image. Another workaround without going this route is by uploading the image first and you should be able to retrieve the URL of the image. Query ID information from wordpress database table called wp_posts where image id is equal to the name of the image uploaded. From there, you can then set the ID to wp_post_thumbnail. Thanks a lot.

Django-Postman disable email notification per user
That code says that django-postman reads a setting (from your settings.py file) called POSTMAN_DISABLE_USER_EMAILING, and if no value is set, it defaults to False. The docs say: POSTMAN_DISABLE_USER_EMAILING Set it to True if you do not want basic email notification to users. This setting does not apply to visitors (refer to POSTMAN_DISALLOW_ANONYMOUS), nor to a notifier application (refer to POSTMAN_NOTIFIER_APP) Defaults to: False. However, that turns emailing on and off across the whole system. To disable user emailing on a per-user basis as you request, this code in postman/utils.py points to an answer: if notification: # the context key 'message' is already used in django-notification/models.py/send_now() (v0.2.0) notification.send(users=[user], label=label

iOS tweet image - Can I get the image url before upload?
1) I don't see how you plan on conjuring an image URL before you upload the image - that is a chicken/egg situation. I would recommend taking a look at an actual image URL after you upload it to facebook, twitter, etc and try to figure out even one character of what it would be for the next image you upload. Regarding twitter specifically the image URL is also going to vary depending on what upload service is being used. 2) regarding uploading the image and getting the URL why not look into tapping into the flickr API?

Rails: Upload CSV file without header
You could just load the CSV file into an array of arrays and remove the first row: data = CSV.read("path/to/file.csv") data = data[1..-1] However this will store the data as an array of values only. When you use headers: true it uses a hash where the keys are the column header names.

jquery file upload rails redirect
there's a couple of things you have to consider. First, you have to be able to get the url to the edit action. If your js is in the page and not in an asset file, the following change should work. jqXHR = data.submit() .complete(function() { window.location = "#{url here}" }) you also need to use <%= %> if you are using erb instead of #{...}. If this is in an asset file, you don't have access to instance variables so you have to rely on the response of the server. As an example, you can set the response to be json. $('#fileupload').fileupload({ dataType: 'json', add: function(json) { jqXHR = data.submit() .complete(function() { window.location = json.url }) } }) since you're using json.url above, it expects you to return the url in the json response so in your

Rails - Upload and parse multiple CSV files
Well, as far as I see. This behavior shouldn't actually be happening. I would suggest another way of doing this code, since it's looking a bit polluted. def import (1..x).each do |i| #with x being the max number of files uploaded at the same time RatingSet.multi_uploader(params["file_#{i}".to_sym]) end redirect_to "/multi_uploader", :flash => { :notice => "Successfully Uploaded." } end Either way, this shouldn't solve your problem. I can't tell why this is happening to be honest. UPDATE: Have you considered using: <%= f.file_field :file, :multiple => true %> instead of mutiple file_tags?

Your other option is to use http://json2csharp.com/ to generate a class file that matches the layout of the JSON and will allow you to deserialize into an exact object.

How upload multiple photos at the same time?? Ruby on Rails
I would suggest using a gem such as Carrierwave or Paperclip. In your view, to allow multiple file upload, you may need to implement asynchronous file upload. A very handy way to do this that uses jQuery is a plugin called jQuery-file-upload (which can handle multiple files). Ryan Bates has an excellent video on Railscasts jQuery File Upload on how to do this. There's also a gem that prepackages this jQuery plugin for you, called jquery-fileupload-rails.

jQuery-File-Upload Plugin integration into Rails
I think what instruction #4 is telling you is to simply copy the various javascript files into your custom server environment, in this case, Ruby on Rails. It's best to use the assets pipeline to serve up Javascript in RoR. 1) download and extract the archive to your development environment, you want to extract the folder JQuery-File-Upload to app/assets/javascripts directory. when you are done you should have: /whatever/app/assets/javascripts/JQuery-File-Upload/stuff So now, you have to tell rails WHEN that javascript needs to be loaded. To keep things easy we are going to assume that that javascript is needed on EVERY page! If your current app is fairly 'default', the javascript manifest file: app/assets/javscripts/application.js controls the javascript that will be incl

It could have to do with the .read call on line 2. Somehow inputFile is turning into the contents of the csv and not the name of the file itself.

Rails - MassAssignmentSecurity:: Error on multiple photo upload
Just add photos_attributes to the attr_accessible list in the Product model. Or even better, try to migrate to strong_parameters gem, will save you sometime when you migrate to Rails 4. Update In create action, you create a @photo variable from params[:photo], which is knows to return nil, yielding the object invalid always. That said, you don't need to create that variable as Photo objects are already made for as you use accepts_nested_attributes_for already. I understand that you need to know if the Photos are created successfully, but you shouldn't be worrying about it as errors from product's new photos will propagate to the product, stopping the saving process.

Rails 4: upload attachments to Amazon S3 before saving model
I can think of 2 approaches: Go ahead and save the note, but have a column on the model that tells you whether or not it's temporary. If the user clicks save, then you change that column from temporary to permanent. You could run a rake task in the background to clear out temporary notes that are more than a day old, etc., if you wanted to do that. Put some sort of reference in the image's file name. You can't use an id, since that won't exist yet, but you may have other unique identifiers such as a combination of username and post title. If you can do the 1st option, I'd say it is much preferable. It gives you a unique ID for the note, which has the express purpose of making it possible to reference the note externally.
