问题 I have a setup with a traditional form that's checked with jQuery Tools validator and submitted via POST. I like that this class does not require extra classnames or other superfluous metadata to validate, standard HTML5 attributes are enough. I now would like to extend this functionality with the Plupload upload solution. I know that all modern upload solutions work via Ajax these days, so I was thinking about a setup in which the user fills out the form, puts files in the upload queue and

问题 I have a form with an input type=file . Internet Explorer lets the user type anything they want into that input (whereas Firefox brings up a file chooser). If the user enters a blatantly invalid name, for example: a and tries to submit the form, Internet Explorer does not even try to submit the form. Is there any way for me to know that this has happened and let user know this is happening with an alert? 回答1: You should add an "onclick()" event to the submit button which calls a JavaScript

问题 I have a Perl app that runs some perforce operations, in the end I would like it to upload the results to SharePoint website. What is the simplest Perl script that can accomplish a task of adding a document to SharePoint? The script would need to run on Solaris and use as few as possible external libraries as possible (definitely pure classic Perl) getting anything additional installed on these unix boxes is a pain and would have to be done by remote team. If this can uploading document can

问题 I'd like to store uploaded files into a specific directory that depends on the URI of the POST request. Perhaps, I'd also like to rename the file to something fixed (the name of the file input for example) so I have an easy way to grep the file system, etc. and also to avoid possible security problems. What's the preferred way to do this in Django? Edit: I should clarify that I'd be interested in possibly doing this as a file upload handler to avoid writing a large file twice to the file

问题 Like many variables in PHP using ini_set() on a page doesn't actually work. I've recently upgraded my PHP version and found that my multiple image uploader is now capped. After 3 hours of frustration, I've found that my new PHP install has the new "max_file_uploads" parameter set to "20". So only the first 7 images get uploaded (each is in three sizes, 7*3=21). I can now change my php.ini value of "max_file_uploads" to 300, but I'd rather not do that side wide. Is there any way to set that

问题 I have a Zend_Form with file element like this: ->addElement('file', 'image', array( 'required' => false, 'label' => 'Venue Image', 'validators' => array( array('IsImage', false), array('Size', false, '2097152'), array('Upload', false), ), )) And when I'm using localhost the image is uploaded successfully. But when I move to my hosting the validation error shows for image field. The mimetype of file 'foto.jpg' could not be detected. What can be the reason of this? 回答1: same thing happened to

问题 I'm trying to make an image upload script with laravel 4. (using Resource Controller) and i'm using the package Intervention Image. And what i want is: when uploading an image to save it as 3 different images (different sizes). for example: 1-foo-original.jpg 1-foo-thumbnail.jpg 1-foo-resized.jpg This is what i got so far.. it's not working or anything, but this was as far as i could get with it. if(Input::hasFile('image')) { $file = Input::file('image'); $fileName = $file-

问题 I have a Meteor app and would like to upload data (from csv) to a meteor collection. I have found: solutions (e.g. Collectionfs) which deal with file uploads methods for uploading directly to the underlying mongo db from the shell references to meteor router - but I am using the excellent iron-router, which does not appear to provide this functionality My requirement is that the app user be able to upload csv data to the app from within the app. I do not need to store the csv file anywhere
