Hi,
I am fairly new to php3 and mysql. I would like to know how it is possible to make sure that only unique field entries can be made (ie. if the telephone number 123456 is already taken it cannot be registered again). I would much appreciate any help.

Thanks

Use the UNIQUE keyword when defining the field.
