I have reviewed a few PHP/MySQL code generators, but I couldn't find any which can do a multi row update much like the way you would do a spreadsheet with a single save/submit at the end.
Everything I see seems to allow updates "1 row at a time".
I need to be able to update an entire column with a single submit at the end.
There should also be a confirmation page before committing the change for any web cells which have been modified.
Does HTML have a way of detecting changes in cells via a boolean flag? I prefer that method over having PHP compare the before and after values.
