I want to prevent duplicate entries in by database in the hostname
field.
So far, I have modified my hostname column as such to prevent duplicate
entries into it, it works:
alter table <table> modify <column> varchar(15) null unique;
Now I need to notify the user that enters a duplicate hostname of their
error, the database prevents the entry, but the user dosn't know it.
Here's my PHP script, any thought how best to modify it?
THX!
