Defining Form elements based on db ids
I am just starting out with Struts and I am trying to do something fairly simple. I have a form with 1 to x number or rows that were retrieved from a database. Each one can be selected via a checkbox. Initially I wanted to name the checkbox process_xxx where xxx is the key from the database (i.e. process_345; process_621...) - that way I can easily tell which rows were selected and do my backend processing. I don't think I can do this being that the form class has to have the fields defined beforehand. What is the best way to go about what I am trying to do? Is the indexed attribute intended for this use? Thanks, Mike -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Defining Form elements based on db ids
The easiest way to do handle a list on a form is with an index. Use the logic:iterate tag to iterate the list. For the checkbox you use something like this: input type=checkbox name='%= name[ + index + ]%' value='%= value[ + index + ]%' Marcel -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 13, 2001 5:57 PM To: [EMAIL PROTECTED] Subject: Defining Form elements based on db ids I am just starting out with Struts and I am trying to do something fairly simple.

RE: Defining Form elements based on db ids
Thanks Marcel, but I wanted to use the Struts html:checkbox tag. Is there a document or FAQ that someone can point me to regarding dynamic form elements?
