Gurus,
I've created the following file (see HTML/JavaScript code below) which
allows end-users to dynamically (on the client-side) move items from one
form select list (called "list_managers" to another (called simply
"managers[]"). When, however, I attempt to access the end-user created
"managers[]" form select list with PHP, I'm unable to do so! My testing
(using the empty and isset functions) revealed that the "managers[]" array
shows up as being empty, even though items were added to it from the
"list_managers" select list prior to the form's submission. Has anyone
encountered this problem before? What am I doing wrong here? Are there any
suitable workarounds?
P.S. Thank you, in advance, for all of your help and cooperation.
