问题 I am using the https://github.com/blueimp/jQuery-File-Upload It uses XHR file uploads in modern browser and hidden iframe uploads in oldIEs (8,9). The server returns a 4xx status code (error/fail), when file validation failed. $('#fileupload').fileupload({ url: url, dataType: 'json', done: function (e, data) { console.log("done") }, fail: function (e, data) { console.log("fail") } }) However in oldIEs the done callback is called even when I send a 4xx status code. Is there a way to make it

问题 I am using jQuery File Upload plugin (http://blueimp.github.io/jQuery-File-Upload/) for image upload for my website. I want to add image from URL, when user add in textbox. 回答1: You have to find a way to download the image from the URL, convert the img into any Type supported by the blob constructor, build a blob file, and call the jQuery File Upload add method like $('#fileupload').fileupload('add', {files: blob})', all grammatically with javascript.

问题 I have a weird problem with jQuery File Upload plugin.

问题 I need to use the formData parameter available in the jQuery File Upload control to send additional data to the server on submit. The default implementation for formData is to invoke a function that grabs all controls in the form and serializes them to an array (using the jQuery serializeArray() method). I have controls in my form, but when the file is uploaded, I am not getting any additional data. When I inspect via Fiddler, there is nothing in the request that shows these form fields are

问题 I'm using the jquery file upload script and have had success uploading the main image to Amazon S3. I'm now trying to swap out the multiple image sizes for uploads to sub folders or objects in S3. Inside the create_scaled_image function in the UploadHandler.php file how do I replace the imagecopyresampled call with an S3 call? Is this even possible? Here is what does the image resizing and writes the file out: $success = $src_img && @imagecopyresampled( $new_img, $src_img, $dst_x, $dst_y, 0,

问题 Edited With the jQuery File Upload Documentation I am able to save Data with the pictures in MySQL DB (see pic 1+2) Now where I'm stuck is how to retrieve the Data back. After the Upload I would like to show the pics with the Data from DB but there is nothing I can find how to do that.

The json now

问题 I'm using jQuery-File-Upload with jQuery-Iframe-Transport to try to get support for older versions of IE. I've set the forceIframeTransport option to true so that it behaves more or less the same way in all browsers, but I don't seem to get any data back on the server-side regardless of browser when it uses the iframe transport. I've spat out the request headers server-side and I get back: array( Host => "*******" Connection => "keep-alive" Content-Length => "0" Accept => "*/*" Origin => "***

问题 I am wondering if this flow is possible: Click a button that says "Upload". It is styled very differently from the usual . It does not show the "No file selected" text. The usual file browser pops open. The user chooses a file to upload. They click the "open" button in the file browser. Upon clicking "open", the file browser is closed (like normal) and the file immediately begins uploading (unlike normal where it requires a submit). I detect when the file is finished uploading, and direct to
