Re: Webpage response to selection & $_POST

It doesn't look like you're actually retrieving data using the $_POSTed data from that code snippet. Are you doing anything like $j = $_POST ['j']; in order to get the value of j before you retrieve your array data? Or are you allowing PHP to declare $_POST variables globally? The reason you need brackets is because brackets are always used in the declaration of a user array, assuming that this is what you want. If you don't want an array, than your original code was correct -- [] always signals an array type to PHP. -- Peter Ellis - pellis@naturalaxis.com Web Design and Development Consultant naturalaxis | http://www.naturalaxis.com/ On Mon, 2004-08-30 at 11:02 -0500, Philip Thompson wrote: > Peter, > > On Aug 29, 2004, at 6:26 PM, Peter Lovatt wrote: > > > Hi > > > > you need to check for $_POST["user1"], $_POST["user2"] etc - is that > > what > > you are doing? > > Yes, this is how I am checking the post variables. > > > > > Your other variables are done as an array - $firstName[$j] etc, should > > your > > check box be > > > > echo ' <td><input type="checkbox" name="user[' . $j .
