Searching the forum I found this:
Checkbook
It is php/mysql, perhaps you can use it.
I do not know how dynamic you would like to have it, I would just publish screenshots of the respective excel sheets as a quick solution.
Was hoping to find one that would run a simple test before displaying the Post Comment to find out if th user ogged in was the Administrator. If the user is the Administrator then to display a button in the comments tool menu for spreadsheet. Upon clicking of that button a small popup (hidden div would work better 😉 ) that would ask how many columns and how many rows. The Administrator would input the information and then voila the spreadsheet would appear in the comments. Then all they Administrator would need to do is click in each box and input the appropriate data. I am sure I could create a similar mod if I knew of a way to allow only Administrators to insert html into text but the downfall to my solution would be that once they inpur the how many columns/rows then the Administrator would need to go to each line of html and replace the “TEXT HERE” with their individual text. If anyone would find use of this let m know about the Admin only portion and I will try to put something together. Still never new to PhP but the few mods I wrote in ASP have helped me out a bit with the code.
