Disallow Characters Like %$& In A File Name In An Upload Form
Aug 30, 2010
i have a html/php form which let users upload pictures onto my server. the problem with it is, it says the picture has been uploaded but if the file name contains any of character apart from text (A-z) and numbers, the picture never shows up in the admin panel.
is there a way using ajax or jquery to disallow certain file names in the upload field of the html which uses these characters !@#$%^'&*()"?
I have a problem with the latest version of the jQuery Form Plugin (2.80). To be more precise, I guess I am doing something wrong, and with an older version (2.67) somehow it didn't matter.With the old version, the file was uploaded without problems. Now Firefox opens a new Tab on clicking the submit button and nothing is done. Chrome doesn't open a new tab, but also nothing happens. In Wireshark I can see that there is no file attached in the POST message with the older version, the file was sent.My first guess was that my file handling on the server side is erroneous - but on the other hand, when there is no file attached, what should I handle there?
I implemented Malsups jquery form and use it for ajax file uploads. Works fine in FF, but in IE as soon as the ajax has completed the upload IE gives me a File Download box - Security warning. If I click on save it save thereturnedJson object (I do JS call onsuccessto get a file list and display it). If I click cancel or save on the popup has same effect the file still gets uploaded but just looks ugly.
How can I get rid of this? All coming form the same domain, calling from the same domain. This is on a python django project and I am testing it on the dev server.
Its pretty basic jquery nothing to exciting, don't get why IE would cause.
I am trying to upload a file from a HTML form using jQuery and PHP. I have the following script, which I just need to adapt to add the support for uploading files.
I am trying to implement this jQuery form plugin to do ajax file uploads. Although the documentation is great I am still a little unclear about one thing. Usually when I do ajax submissions I return a response in JSON(using PHP), something like :
When doing some simple tests I have run into a problem and I believe it is due to the way this plugin handles JSON responses. My form :
[Code]...
This does not result in the success event firing but rather the error event. In the plugin documentation it states that it does not handle json responses well and that it recommends wrapping the response in a textarea. Unfortunatly I'm not sure what they mean by that, and what I've tried so far has not worked. ould anyone give me some advice as to how to output the response in JSON properly? Could anyone that has used this plugin for AJAX file uploads offer any advice on doing so?
I have a page users can click to upload a photo. When users click I want a modal window to pop up with a simple file upload input inside it and a submit button. I have this working except that when users click submit nothing happens. I'm using nyroModal [URL] and the code I use is:
If I take the code out of the div=id"test" the form appears on the normal page and submits just fine. Inside the test div tho the modal window pops up with the form inside but the submit button does nothing.
I'm a CSS and PHP developer, finding myself using jquery and AJAX more and more, of course, and learning a little about it as i go. but only a little. :o)i have a client who's asked me to add an image upload feature to a simple comments post script i've "built". i can see, kind of, how this jquery is posting the form text inputs, but have no idea if this thing can even be made to post a file at the same time.Hoping someone might add a function for me to do this if it can be done?
$(document).ready(function(){ /* The following code is executed once the DOM is loaded */ /* This flag will prevent multiple comment submits: */
I've a form having input feilds name , email, image and comments. I want to submit the form without page refresh and upload the file on server using ajax jquery in php language. i
I've added file upload support to the form plugin and I could use some help testing it out.If this feature interests you then go ahead and grab the beta plugin at:URL...File upload support is baked right into the plugin and there are no external dependencies.The plugin will automatically detect file input elements and use an iframe to submit the form if there are files to be uploaded.No extra coding or metadata is needed to take advantage of this new feature.In addition, even though an iframe is used instead of the XHR object, callbacks and global triggers still work as expected (so any code that you have in place to display activity indicators or blocking elements will still work).However, there are some challenges when using iframes in this manner.For one, it is quite difficult to determine if the submit operation succeeded or failed.The iframe becomes the target of the submit operation and so that is where the server response is written.The form plugin does its best to determine the data type (html, xml, etc),but the status is always 'success' unless an exception is caught during the type determination.URL...
If you use this page for testing *please* be kind to my server and only upload small files! I'd really prefer that you download the plugin and integrate it into your own test environment if possible.I've done some testing on FF, IE and Opera and the results are encouraging. I don't have access to Safari so I'm sure there are issues lurking for that platform.If you're interested in the code you can find it all tucked into the end of the ajaxSubmit method in a function called "fileUpload".
I am quite new a web scripting and making web pages in general and I have stumbled across a problem I have as yet been unable to solve. I am trying to take the contents of a textarea box and save it to a file. This step is not to hard however the contents of the textarea is mostly latex source so it contains just about every special character you can imagine. My question is this, how do I save an exact copy of the textarea contents with special characters, carriage returns, etc to a file?
Just wondering if anyone knew how to make it so that if someone types an apostrophe in a form's textbox, a popup box appears. The popup box would preferably appear the second that the apostrophe is entered int he form box and then once the popup box is closed, the apostrophe is deleted.
I'm was able to successfully use your plugin for firefox, safari, chrome. When the form submits the request with file upload, here is the html I send back to the browser (via Rails): <textarea>{'status': 'success', 'avatar_url': '<%=@user.avatar.url(:medium)%>'}
This is driving me nuts. I'm using the File Upload. It works fine in Chrome, but in FF4 and IE9 it executes the beforeSubmit, but never reaches the success, and the file never reaches the server.
I'm novice with jQuery and Web in General and I have a problem with "jQuery Form Plugin" [URL]... Everything works well except when trying to upload large files (I need to upload video files).Itriedupload a video with about 24 MB in the example(demo) page in the[URL]../#file-upload and seems that i don't get the expected result. Can you tell me what constraints or custom options i'm facing with this plugin or IIS7 for that matter? Is there a way to see that something went wrong? Because the file seems to be uploaded but nothing happens after.
I'm trying to put in place a file upload validation check. So at the client-side, the User selects a file. Before uploading, at the GUI, if the file exceeds an imposed limit, it will prompt the User that it exceeds the permitted size for upload.
And if it is within the permitted size, the full file path of the file to be uploaded will then be obtained and then used for the actual upload to the Server.
My program is built on EXTJS and Java, running using Tomcat. Browser restricted to Internet Explorer 7 only.
I am looking for a upload form to upload pictures and then when the pictures are uploaded, then they get emailed to me. Kind of like a contact form but attached is the pictures.
I know that the input "file" type can't be customized very well using css, so I figured I might try to make my own with javascript. The only problem is, I don't know too much about javascript. point me in the right direction on how to make my own custom file upload box in javascript that works the same way as the default one works (so I don't have to edit my PHP coding). Also, heres something I'd like to achieve: [URL]
I am wanting to simplify a page that I'm writing... the guts behind the page is PHP and wondering if it's possible to upload a photo in one click. How would I approach having the browsed file detected once it's populated into the form field and have it auto uploaded? Can this be done?
