adding a file to a directory

[igpxnaruto4]

so i have a pic editing website set up, and i have a function which lets you download images.http://jsfiddle.net/9Ytsk/ is what it looks like. what i want it to do is also generate the image to a different directory (gallery/gallery), and add +=1 if the image already exists (ex. image.png exists so it's named image1.png). Thanks!

If you're talking about saving a canvas image on the server, there's a discussion about that here: http://stackoverflow...age-on-a-server Renaming would involve something like this, in PHP:

$fname_orig = 'image.png';$fname = $fname_orig;$nr = 1;while (file_exists($fname)){  $chunks = explode('.', $fname_orig);  $chunks[count($chunks) - 2] .= $nr++;  $fname = implode('.', $chunks);} echo $fname;

i tried everything and i cant seem to get it to work. right now i have this set up - http://jsfiddle.net/9Ytsk/2/ i added that php part (does nothing on jsfiddle). and i forgot to mention on the main post that this is for a webpage which im using dreamweaver for (it doesn't display errors so i cant check the code). thanks

It's going to work to run that on jsfiddle or Dreamweaver, you need an actual PHP web server. The PHP code is only half of it, you also need the ajax code to send the image data to PHP. That's how the image data gets from Javascript to PHP. PHP gets the image data from Javascript and creates a file on the server.

i really don't have much experience with this type of stuff. i was looking at

		    var url = canvas.toDataURL("image/png;base64;");		    downloadImage.attr('href', url);

of the js and was wuondering if changing this (downloadImage.attr('href', url); ) in any way could possibly make it generate the file?like for example downloadImage.attr('./gallery/gallery', url);or url.copy('./gallery/gallery');Thanks

This line: downloadImage.attr('href', url); Sets the "href" attribute of the downloadImage element to the given URL. The downloadImage element is a link on the page. So if the URL says "test", then that line is the same as doing this: <a class="downloadimage" href="test"> So it doesn't make sense to do this: downloadImage.attr('./gallery/gallery', url); which would be the same as this: <a class="downloadimage" ./gallery/gallery="test"> It doesn't mean anything to do that, it's not a valid attribute for a link. Javascript cannot save files. If you want to save a file you have to use something other than Javascript. Javascript can get the data you want to save, but it needs to send it to something like a PHP script which can actually save a file. Javascript just runs in your web browser, it can't save a file on the server. It can't do anything with the server except send requests to it. PHP runs on the server, it can save files there.
