I have a form button that submits the data to generic script (the same page that the form is loaded from, index.php) and if the right POST variables are submitted to that script, it returns a PDF for the user to print (with the relevant form info loaded, and other DB info, etc).

Hi, I want to parse the contents of a dynamic .csv file.

I have a directory of images that alternately be viewed directly in the browser, and other times downloaded. So, say I have a file /gallery/gal_4254.jpg.

Content-Type: image/jpeg; name=image0.jpeg Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename=image0.jpeg Content-ID: <image0> Gmail seems to modify the headers for some reaso...
