Menu
I am building a form where a user will have the ability to add items from selection lists. The items will be stored in session arrays after beeing added.
The user will also have the ability to remove added items and that is the problem: I don´t know how to build such a function.
I have added [b]echo “<a href=”#” id=”remove” onClick=”document.forms[0].submit(); return false”>Remove</a> <br />”;
Please, help!
