file-upload

问题 I have a file upload input and when I click the browse button and select the file, I want the filename and extension to appear in two input text boxes (see code sample). It works correctly with the extension, but the filename also shows the path which gives me the fakepath warning. I understand why, but what's a good way to do this and just get the filename into that box. I don't need the path. function getoutput(){ outputfile.value=inputfile.value.split('.')[0]; extension.value=inputfile

问题 I'm using Uploadify and Kohana and I'm creating file uploader. User can upload only few types of files. Kohana have great library of MIME types built-in. I thought that it would be cool to check that MIME type of uploaded file (it came from Uploadify) match setted file extensions. That's why I made an array of allowed MIME types. $mimes = (array) Kohana::config('mimes'); $allowed_mimes = array_merge($mimes['bmp'], $mimes['gif'], $mimes['jpg'], $mimes['jpeg'], $mimes['png']); Next, I wanted to

问题 I'm trying to make dynamic upload path to FileField model. So when user uploads a file, Django stores it to my computer /media/(username)/(path_to_a_file)/(filename).

问题 On image preview, when I select a video, an empty image box is displayed on the right side of the video image preview. And when I select a picture, an empty space is displayed on the left side of the picture image preview. So both <video> tag and <img> tag are displayed together.

问题 I have a form in Symfony where the user uploads files to. These files can be up to 50Mb in size. However, when I try to upload a file that is about 10Mb (before this, the files were no bigger than 7.2Mb) the form reloads with this error: The uploaded file was too large.
