upload

I've been using rails for past few days and wanted to know what is best way to show image previews before upload in rails & carrierwave. I came across a few options like using plupload or jquery file upload or using uploadify. If you only need image preview in a form before upload, you (as me) will see that JQuery Upload plugin is just too much complex and not so easy to run properly (I was able to see the preview, but then I couldn't upload the picture). http://saravani.wordpress.com/2012/03/14/preview-of-an-image-before-it-is-uploaded/ It's simple and fast to code. I put the code here just

Answered by me bellow When I try to upload my .APK file i get this error: Upload failed I have tried cleaning my project, exporting it, and running it about 100 times over a span of almost 24 hours. This is just an updated version of my .APK. I have already successfully uploaded several updated .APK to the play store. I changed the Version and I am using the same keystore for this update as I have for all my other updates. Any suggestions? And sorry that this isn't a code specific problem. Also I only made a small edit to one of my activities. The problem has nothing to do with using Chrome.

I want to use ajax to upload image. In this module: On clicking browse and selecting image, it will be uploaded and displayed over file field. After adding title and description, and clicking on the button, that image will be displayed below and upper image field will be blank You can't upload files through AJAX. You need to work with IFRAMEs or a Flash-Based uploader. Actualy you can upload images with the ajax function in Jquery in atleast the lates version of chrome. HTML: <form action="/" enctype="multipart/form-data" method="post" accept-charset="utf-8"> <input type="file" name="image"/>

I have about 4000 records that I need to upload to Datastore. They are currently in CSV format. I'd appreciate if someone would point me to or explain how to upload data in bulk to GAE. You can use the bulkloader.py tool: The bulkloader.py tool included with the Python SDK can upload data to your application's datastore. With just a little bit of set-up, you can create new datastore entities from CSV files. I don't have the perfect solution, but I suggest you have a go with the App Engine Console . App Engine Console is a free plugin that lets you run an interactive Python interpreter in your

Can anyone please tell me how to store images in an oracle database as BLOBs using PHP? A working example would be nice. Thankyou. DRiFTy You first need to get the image that is being uploaded from the $_FILES #global array: $image = file_get_contents($_FILES['image_field_name']['tmp_name']); Then to insert the image in the database try this: $sql = "INSERT INTO table (id, image) VALUES(1, empty_blob()) RETURNING image INTO :image"; $result = oci_parse($connection, $sql); $blob = oci_new_descriptor($connection, OCI_D_LOB); oci_bind_by_name($result, ":image", $blob, -1, OCI_B_BLOB); oci_execute

I am looking for a solution to upload multiple files (click on browse button, and select multiple files using shift key). I see several solutions that need to be uploaded one by one by clicking browse button, and click submit button. But I need to allow users to select multiple files at the same time. The <input type="file"> is heavily locked down by the web browser due to security concerns. It does not allow multiple file selections. You will need to use Flash or Silverlight to do this, or use multiple <input type="file"> fields. You can allow the user to select one file and then provide an
