RE: CFFILE action="upload"
I just posted this to the "cool things about cf" thread as an easy, useful
example of java instantiation.
function bhimginfo(imgfile){
jFileIn = createObject("java","java.io.File").init(imgfile);
ImageInfo = StructNew();
ImageObject =
createObject("java","javax.imageio.ImageIO").read(jFileIn);
imageFile = CreateObject("java", "java.io.File");
imageFile.init(imgfile);
sizeb = imageFile.length();
sizekb = numberformat(sizeb / 1024, "9.99");
sizemb = numberformat(sizekb / 1024, ".99");
bhImageInfo = StructNew();
bhImageInfo.ImgWidth = ImageObject.getWidth();
bhImageInfo.ImgHeight = ImageObject.getHeight();
bhImageInfo.SizeB = sizeb;
bhImageInfo.SizeKB = sizekb;
bhImageInfo.SizeMB = sizemb;
}
It builds a structure called bhImageInfo that holds width, height and file
size (b, kb, and mb) about the image passed to it.
Just call it like so...
#bhimginfo('d:\path\to\image.jpg')#
Then dump bhimginfo to see everything returned
Also... dump imageFile to see a TON of other methods/properties that could
be used.

All,
Does anyone know a way to check a image file's height and width before or
after an image has been uploaded? I'm restrictinig the file type for *.jpg
only.
I want to take the height and width values of the image being uploaded and
see if the values fall within an acceptable height and width range.
Thanks.

You could also just resize the image (using image.cfc) to fit within the range.

Remember that CFFILE works by first uploading or reading the file into the server's RAM and then performing the appropriate actions. Now you obviously have to keep in mind that larger files are a bit more intensive processing-wise on the server, but that doesn't effect the actual file size limitation...just your server's memory.

CFFILE action = upload

Currently working on a document managment application and some fairly large files need to be uploaded and I was curious about the limitations of cffile. >From a 'user experience' standpoint, i know i can use cfflush to present the user with a "file uploading" type graphic or text, so that aspect can be taken care of for the large load time.

cffile action=upload error
I have designed some forms which allow the user to upload jpegs and QuickTime movies to the server. It was working before, but now I am getting the following error: === Error Occurred While Processing Request Error Diagnostic Information Request canceled or ignored by serverServer busy or unable to fulfill request. The server is unable to fulfill your request due to extremely high traffic or an unexpected internal error. Please attempt your request again (if you are repeatedly unsuccessful you should notify the site administrator). (Location Code: 26) === I am running a browser and the CFserver on the same machine for testing. I'm the only person hitting the CFserver, and like I said, it was working before (with more CFML going on on the same page). What could I have changed to cause this error? When it was working before, I was uploading 3 jpegs and a quicktime all on the same page and it worked fine; I just figured it would be more scalable if I made each one a separate page.

RE: cffile action="upload" accetps all file types
Doug: I'm doing a similar thing with accept = "image/gif,image/pjpeg,image/pjpeg" instead. If the user tries to upload a bmp then, and error will be raised which I can catch... even if it is a bmp simply renamed to a jpeg.

I am using the below code to upload some text files, if the file has an .csv extension is will fail the test and get the error, if I just rename the same file with no extension it works ok. I though the accept="text/plain" looks at the file contents not the extension. Any recommendations on how to get around this? Thanks,Adrian The File Cold NOT Be Uploaded.
