Form Questions

I'm pulling data from a data base and for every record I create a radio button
something like

where $id is the key for a given record in the data base, on this page the users can select from all the records listed (clicking in the radio button) and click the submit buttom to send all the information, the problem is that I cant figured out how can I know which records were selected in the previous page, even when I have the name of them, how can I do to know which one were selected or which were not.

Does anybody have any idea, thanks in adv. sanddy

Well, since you are using radio buttons, only one can be chosen. So look for the variable $Sid. That will store whatever value is in $id for the selected radio button

all the radio buttoms have different names, let's say that I display 100 records from the data base and the user select 5 of them and clicks submit, how can I know which record were selected, if I use isset, it will always be true since the variables are legal even when they were not selected, I dont know if I'm explaining this clearly, please anyone have any idea?

Gotcha...so basically you are treating the radio buttons just like checkboxes....
probably the easiest solution would be to use checkboxes. Then you can check to see what exists. Checkbox variables are not transmitted if not checked. The variables just kind of go away...😉
If this is not an option, then you probably want to loop through php_track_vars(I think thats it), and see what variables are actually populated, and not just null
hope this helps
