Thanks for the help Duncan Hill wrote: > Use different variable names. Or make your function return a value, and > use assignment to handle it. Finally I made the function to take the select name as an optional variable and used different names for the two. This helped me in other situations also. Thanks a lot.

The flow is like this: Browser requests page. Webserver serves page, after parsing (if needed). Browser displays page to user, and essentially disconnects from webserver. User fills in form. Server has no clue as of yet. User presses submit. Browser connects to server and sends data. Server now knows about the data. -- Sapere aude My mind not only wanders, it sometimes leaves completely.

[PHP] Accessing a form variable before the form is posted
My function for generating a select menu for a city sets the select name to form[city_id]. In one of the forms, there is a selection for City in the address details as well as one for the port of destination. If I use the function both the the select name will be form[city_id]. The port of destination selection overwrites the form[city_id] from the selection of City. Is there a way to access the first form[city_id] for assigning to another variable? In short is it possible to access a variable from the form before the form is posted?
