Checking To See If A File Is Uploaded?
May 18, 2011
So I'm trying to create a custom file uploader which will display the name of the file selected, but since I can't seem to figure out how to do this I've settled for checking to see if a file has been selected, but I'm still having trouble with it.Here's what I have...
<style>
#upload {
display: inline-block;
text-align: center;
[code]....
However the value doesn't change after the file has been selected. Could someone tell me a means of modifying this so that it will properly display once the file has been uploaded? Do I need to have some sort of constant refresh on the Javascript to check to see if the value has been changed?

I'm trying to make some kind of progress bar using AJAX and PHP.
I want to check the size of tmp file (before it moves to the destination dictionary) during it's being uploaded.
Is that possible to check the file size of tmp file that is being created when someone click on upload form button, before it's fully uploaded.
I noticed that you can do it only after the file is already uploaded so only after isset($_FILES['name_of_file']) will give the truth.

I would like to create a script that behaves differently according to the date it was uploaded to the webserver. Meaning - if I send the script to my friends and each one uploads it to his server on a different date - each one will get a different behavior.
Something like:uploaddate=getuploaddate();
if uploaddate between Jan 1...Jan15, 2010
do this1;
elseif uploaddate between Jan 16...Jan31, 2010
[Code]...

I am using uploadify (a jQuery plugin) to upload files as I am adding clients to my DB. I would like to attach files to clients. The issue #1 is that the client is a new client so it has not been added to the DB just yet. I have overcome this by getting the next Client_ID in the DB.
NOW the real issue is that all files that are uploaded should be prepended with this ID...something like: (29) ---i would like the parenthesis as an added open and close of the client_ID----I have searched on stackoverflow and uploadify.com but can't make heads or tails on how to do this.
I NEED TO DO IT VIA JS, because of the fact that I am using the PHP elsewhere in my application and I don't want to change it, if at all possible.

I would like to be able to delete an uploaded image file whenever a PHP page is navigated away from, either by the use of buttons on the page or the browser arrows.
I want to do this to stop a directory being filled with 'leftover' files.
I think that using an onblur function with the <body> tag would enable me to do this, the problem is that the filename is a PHP variable.
I have searched for an AJAX function that would enable me to do this, but haven't been able to find one.
I have a PHP script for uploading and cropping an image file, this file is selected by a form that calls the cropping script.
In the form there are buttons to Crop, Load File and Exit.
The Crop button starts the cropping process and finishes by deleting the original file.

I am a total newbie, but am trying to get my feet wet by adding some JavaScripts into/onto my website that I am creating. I am trying to have people "upload a file" which will then take them to my order page where it will tell them how many words their "file" has, then in the background divide the number of words by 350 for the page count then multiply by my price per page, then display their cost of their job? I seen one like that on another website [URL].. but cannot figure out how they did it. I'd like to be able to put this at the top of my order page where after they see the cost, they would fill in their own info (which I know how to do) and then submit the whole thing along with payment.

I set up the following code to check how many days have elapsed since a file has been uploaded:
[Code]...
alert("Days since file was uploaded="+diff); My problem is that modified.getTime() doesn't work. Apparently the result of Oxml.getResponseHeader('Last-Modified') is a string, such as Sun, 21 Nov 2010 21:17:49 GMT. I tried and tried - but couldn't get to make a proper date out of this.

I have a site with a news pages and I'd like the navigation to include a
blinking 'NEW!' when that page has been updated within the last three days.
It works fine for the one page (if you're on the news page, it works great)
but I can't figure out how to check the time/date stamp on a file other
than the one currently loaded ...

I have seen many Javascripts on Internet that checks the extension of the file before uploading. But all these scripts checks the extension when the Submit button is pressed. I want to check the file extension as soon as the file is selected. The script should delete the selected file from the type=file box and display an error message (when a file with the wrong extension is selected).

In client side, we can check if some image exists using onerror. I wish the same behavior to check files used in object tag (in client cache, not in file system), like swf, wmv and wma, etc.

I was looking in the firebug debugger and noticed that my main .js file was somehow being called twice, but I don't see where. There are dozens of files involved in this particular problem, so I think the best way to go about solving it is to test - in run time - if my js file is already in place on the page, do nothing - otherwise call it. This is pseudo that I have monkeying around with but it's not working.
Code:
function checkFile() {
var fileExist = new fileExist();
fileExist.onLoad = isPresent;
[code]....
I thought this would work, perhaps it's because of an argument I need to pass in to checkFile(ZYX) but not sure.

Is there a way using javascript to have it check if a file exists on the server? I'm trying to check for a file on my server without having to refresh the open webpage. If this can't be done with javascript, do you know which webpage languange can execute this?

I'm try to set up a webpge that will play a live flash video on the left-hand side(got that part working) and display one slide of a presentation(jpg) to the right of the video. I would like to be able to control when the slide image changes by having some js check a text file on my server. The text file could contain something as simple as "Slide1.jpg". I will manipulate the text file with some code I've already written. Is there some simple js code I can put in my page that will cause it to check the text file every 5 seconds, and if the content of the file has changed, to refresh the image on the page with the new image? I'm try to get away from the "clicking" sound that is caused by doing a simple refresh of an Iframe.

I am allowing users to upload images using an input with a type of file. Ideally what I'd like to do is use Javascript to get the size of the image that their trying to upload and to error if the image is too large.I'm using php to resize the image, but I'd like to warn the user before they submit the form, so they don't have to go back and start again.

I'm a php developer and have come across a mind boggling issue involving Javascript. I'm uploading images to a server without issue. They are being returned to the page in thumbnails.
The script works great but I can't get the links for the images that I've uploaded.
If I right click and view the image I can see the link on the server. How would I go about getting that link? If I look at the source code the link isn't present. Its a dynamically generated link for the uploaded image.
Being completely unfamiliar with Javascript
Here's the code I'm working with:
<input type="file" name="u" size="40" style="width:500px"/><br/>
</div>
<style type="text/css">
.flashUpload {width : 151px;}
</style>
[Code].....

I've been working on a college project to rebuild a php/mysql web application. My local dev. environment runs php/mysql on IIS, and the server that hosts the web-app runs php/mysql on Apache. As part of the revamp I've coded a few bits of javascript that works perfectly in my dev machine, but when upload do not work properly. Here is the latest bit:
Form with hidden fields I want to post to the next page.
<form action="ADToDoPrintPage.php" target="_blank" method="post" id="fm">
<input type="hidden" name="TotalHours" id="TtlHour" value="<?php echo
"$total_hours" ?>"><input type="hidden"
name="TotalCycles" id="TtlCycle" value="
<?php echo "$total_cycles"; ?>">
Then a list of links, one of which posts the form to the desired page:
<li><a href="" onclick="document.getElementById('fm').
submit();return false;">
Printer Friendly View</a></li>
Problem is rather than going to the desired page, it simply directs to the homepage. I'm baffled as to why this is happening and dont know where to start looking. Could it be something do to with javascipt not being enable or permitted on the webserver? I've made sure the site is in the 'trusted sites' list in IE but with no joy.

It states:"The ie6-upgrade-warning is a little script (7.9kb) that displays a warning message politely informing the user to upgrade the browser to a newer version (links to newest IE, Firefox, Opera, Safari, Chrome are provided). The webpage is still visible behind a transparent background, but access to it is prevented. The idea is to force users to upgrade from IE6 and avoid the website from a bad reputation that website is not rendering correctly in IE6.InstallationJust insert the line<!--[if lte IE 6]><script src="js/ie6/warning.js"></script><script>window.onload=function(){e("js/ie6/")}</script><![endif]-->right after the <body> declaration of the webpage and change the e("js/ie6/") to the folder where the script's icons images are located."
So I uploaded the IE6 folder and put the line of code below the <body> declaration and changed the {e("js/ie6/")} to the icon folder.But I don't see any instructiosn after I uploaded the IE6 warning folder. Has anyone used this? Is there somthing I should do after I zipped the IE6 folder and uploaded it?

I am working on the following page: [URL]
There is a news script on the right-handside which rotates news items (a kind of scroller).
Locally this works without any problems, but once I've uploaded it to the hosting server this doesn't work. There is no javascript error sign.
I have double checked with the hosting and they support javascript by default.
