getting image dimensions

[Anon]

Will PHP return the dimensions of an image at time of upload? If not during upload, is there another method for getting the dimensions?

Also, I have been working with the input attributes for file uploads in HTML. I am trying to restrict the file type:

<input name="uploadedFile" type="file" accept="image/gif, image/jpeg">

Which should work but I am still able to upload files of any type. Any ideas?

Thanks!

PHP won't automatically give you image dimensions at the time of upload. What it gives you is the file's in the tmp directory it's stored in upon upload, the file's original name from the sender's computer, its size, and its type. See:

http://www.php.net/manual/en/features.file-upload.php

In the script that handles the upload, check the type, and if you don't like it, do nothing with the file. It will be deleted when your scripts finishes executing.

If it does turn out to be of type .gif or .jpg, you can use GetImageSize() -- on either its tmp location or its permanent location after you move it -- to determine its dimensions. See:
