    Set Checkbox State

      OK. I need help please. My setup is so:

      I have 3 SQL tables, a students table, with a column for either of their 8 classes, and a username column. the username is how i track users and the classes column is filled with the Class_ID when the user is added to the class.  My second table is the Classes table. it contains a class_id column and a period column (there are  8 periods in the day, A1-A4, B1-B4). My third table is the teachers table that stores the Teacher_Username as well as a column for each of their periods, populated with the appropriate class_id

       

      To add a student to a class, the Class_ID is placed into that students row in their appropriate period.

       

      I need to add users, but I can't figure out the checkboxes (I manually added some test users). The page lists all students and a check box next to the user to change their class membership. the form page before it sets the current period and teacher_username.

       

      I have queries to get the correct class_id by teacher_username and period from the teachers table, as well as to get the student username and period to be added to.

       

      What I need is if the user is in the class, the box is already checked. If they are not in the class, the box is unchecked, each student has a checkbox... Can anyone help me on this? Would my current code help? (NOTE: A user is in the class when their period column value equals that of the Class_ID for that class).

       

      Thanks so much!

          <cfloop query="qry_users">
          <cfif not IsDefined("user_#qry_users.UserID#")><cfset "user_#qry_users.UserID#" = 0><cfelse><cfset "user_#qry_users.UserID#" = 1></cfif>

            Thanks, but I'm not sure how that helps. I doesn't take into account whether the users Period column value is equal to the value of the Class_ID I am editing (as set via the form on the previous page...). If the user period column matches the Class_ID i am editing, teh user is in the class, otherwise, they're not...

             

            Thanks for the help!

             

            Would you like to see my code so far? Maybe it will help...

              so this means i am not clear about the request. The descriptions about the logic is ok. Please specify what you want to resolve.

              Yes, provide code, that will help.

                I posted this on two forums, and got an answer on the other one, but thanks anyways. I ended up using an array...
