In a php upload Form when a User chooses an image file to upload, the name of the file appears next to the Choose File button (see attachment) is it possible to grab that file name, add it to the page, and proceed with completing the Form?
Yes, but not with PHP - javascript is your friend, if you want it to appear on the page before the picture is already uploaded. It can also display a thumbnail of the file, if you want, or other information, based on what you deem necessary.
Here is an example on how to do this http://www.itorian.com/2014/01/display-images-and-its-name-size-before.html
