Question

We have a web application that creates a dynamic PHP page with all the MySQL stored details a user has entered via a number a forms. So far so good, but we want this information stored some how to be refereed to at a later date, as an administrator can make changes to the data, which reflects on calculations that are worked out from this saved data.

When going back over this saved data we need to be able to see all the information submitted for that particular calculation, so if that data has changed we will see what is was relating to that calculation. Now we have thought about maybe a snapshot when the calculation is done, pdf of the webpage or something similar would do, but is this simple to do?

I hope this makes sense...

Answer 1

Hmm this is quite difficult to understand. Sounds like you should make a new MySQL table containing snapshots of the calculations and the time they were saved?

What kind of data are you looking to snapshot?

Answer 2

You can easily generate PDF files from a web page in PHP. Many libraries are able to do this. Like FPDF or FPDI (opensource projects).

Answer 3

A bit of a left field answer but you could use Selenium and PHPUnit. Selenium can grab a page and screenshot it, PHPUnit can drive Selenium.
