Forms + While Loops

[supanoob]

Ok so i have a 5x5 grid filled with 25 Option Buttons, now i want to make a loop that circles through them to see which one is selected and then compares that to a number in the database to see if something should be done. Is this possible? if so how?

Post your code so we can see whats going on. Do all the options have the same name attribute?

thats pretty much it. Basically it will be a fishing thing but the fish will move and you have to guess where they have moved too.

You don't need a loop for this. All of your radio buttons have the same name, which means only one can be selected. The value of the selected button will be returned in $_POST['R1'].

so how would i know which part of the grid it is? i was planning on changing the R1 to the Coords on the 5x5 grid. So i would need a loop right? the coords would be like

 

11 | 21 | 31 | 41 | 51

12 | 22 | 32 | 42 | 51

 

etc etc

 

then i would need to do a loop to see which one matchs the number in the db.

[supanoob]

anyone?

[pocobueno1388]

You have all the grids values labeled from v1-v24 which will be stored in the $_POST['R1'] variable. So you will know which part of the grid is selected because they all have different values. Now you would just do a query based on that to see if it matches the one in the database or whatever.

 

If that isn't what your trying to do, you need to explain a little more.
