Hi,
I need a way to do the following:
When the page loads, I have 20 or so checkboxes that correspond to categories a user is a member of. A couple checkboxes may be checked indicating a user is a member of that category, or he/she may have none checked, 2 checked or even all of them.
What I want to do is allow the user to join other categories and/or be removed from categories that they are a member of simply by unchecking the checbox and clicking a button that calls a JavaScript function.
Currently I pass in the memberId and the list of categories they are already subscribed to to an" empty" function called saveCategories. We need a way to know what the user was subscribed to in the event they uncheck those categories we need to do run a DELETE SQL statement and perhaps an INSERT SQL statement as well if the user removes his/herself from category A and joins category D for example. I am thinking the flow should be:
1. Loop through all the "checkboxes" in this form that have an id that starts with "category".
2. Build a comma delimited list of the values of each checkbox.
3. Compare the newly subscribed categories to the original subscribed list and basically figure if I need to just do an INSERT or an INSERT and a DELETE statement
Step 3 could be done on the server side I suppose.
Any help appreciated at least for 1 and 2, I think I can do 3 on the server side.
function saveCategories(memberId,su
}
Best regards,

If you are going to do this AJAX-style, I don't think you need a button, as you can use an onclick event on the checkboxes to trigger the database side of things. What I do need to know is the details of the SOAP service the Javascript will call to do stuff in the database. This way just clicking on a checkbox will change the database.
Alternatively, if this is a traditional form submission, you just need the logic in the server-side transaction script.
Either way, can you let me know how the server-side of things needs to be processed, and I'll provide your answer :D
