Hey there, thank you so much for replying, this is still really doing my head in!
Thanks for the suggestions, that helped :) It's not really an ajax call though. The JS creates an invisible iframe to submit the form into, the php uploads the file and then returns some html with the img src in it which gets copied into the main document by the JS. I've got a bit futher now and I'm getting results returned back, so the onchange is working, the php upload bit isn't though. I'm having trouble figuring out where different things should go. In the default version of the scripts, the onchange does it's thing in JS and eventually passes a bunch of parameters to a php file to process the upload. The problem parameter looks like: 'upload.php? filename=name&maxSize=9999999999&maxW=500&fullPath=http:// localhost/sponster/app/webroot/uploads/&relPath=../uploads/ &colorR=255&colorG=255&colorB=255&maxH=800' How to call this file within cakephp is my problem, Cake wants there to be a controller function. So... in the php file there's a upload function which processes the file and then underneath there's some code doing: $filename = strip_tags($_REQUEST['filename']); to the parameters which were sent before calling the upload function. I tried to split it up into two functions, one which the JS calls (and which then calls the upload function) but that didn't work. It's how to split up the code I can't figure out. Is it not possible to un- cakify things and just open a php file? Once again, I appreciate your help :) On Nov 17, 11:04 am, phpMagpie <[email protected]> wrote: > Barricades, > > The idea of firing of an ajax request (which means your existing page does > not get reloaded) to upload a file and have the files path returned is > relatively simple and I'm sure you will be able to modify any of the > existing plugins to do this, you just need to get a grip on how to use > javascript and what happens when you fire an ajax call. > > What you need to be able to do is debug what's happening with your script. > > 1.
