Re: Problem of a beginner with Array

I want to make a lottery site (just as an exercise), so I made a page with 6 grids of 50 numbers each (check boxes). Now, I want to know which numbers have been checked by the player. I have a : "input name="Grid1" type="checkbox" for the first grid. Grid2 for the grid #2... I was thinking to get the numbers chosen by the player with $_POST['Grid1[]'] Grid1 being a table but it doesn't work. I thought I wouldn't have to declare an array. I have 50 numbers for each grid, I don't want to have to type array followed by the 50 numbers. There is not a way to do something like array(1...50). What is the solution?

Name them like this: <input type="checkbox" name="Grid[1]"> <input type="checkbox" name="Grid[2]"> etc... Then, you can use array_keys($_POST['Grid']) to get the numbers checked. -- ---John Holmes...
