The grid generator code:

This is an improvement over [Adam|Adam's] crossword puzzle generator. Each cell now conatins a 1 character text field, allowing you to actually fill it in and submit your answers to a site. The processing script is straightforward and one can program any number of events to happen when someone solves a puzzle (or submits an incorrect answer) :-). The one in the example is the same puzzle that was written by [KM] [id://29550|here]. Since he said that he would post the answers in a few days, I shall refrain from including the solution in the code. <br><br>
Basically, in order to find the correct solution string to plug into the solution checker, you need to run each block's character together into one long string. It's ugly from a human standpoint, but it's easy to process. I hope to create a dynamic generator in the near future which would, from a list of words and corresponding clues automatically generate the grid, and thereby easily generate the solution string. Enjoy!
