Re: Simple Validation using PHP

Yes, you can use parameterized statements with a UDF.

And Todd...if you're using a UDF that requires parameters, do you treat it
like an SP with prepare, param, and execute?

Stored procedures are used for validation. These are usually external

be very useful when directly invoking an SQL select or update statement.

Good point Todd. Do you use UDFs for validation, or Stored Procedures?

The drop-down list of available values works fine on a browser-based

web service then the input values cannot be limited like that. This
may not be a concern for you but something to consider. I always
try to think of all the ways a "back-end" process can be called.
You generally don't want to rely on "front-end" validation.

Thanks,
Todd

Good idea Paul, and one I'll implement. Still unclear on how to do
validation against information that's dynamic.

I want to be able to use an SQL UDF from PHP, Seems like I need to
use the same method as using an SQL Stored Procedure. If that's the
case, the value of a function seems to be less than expected.

Michael,

If you are validating against data on the i, couldn't you have a
drop down list of possible values? So if you are validating
invoice type or store, then you just allow drop down lists with
the valid entries that way the user can only select valid values?

If you list is large, you could use a type ahead approach as well.

THanks, Paul

execute a stored procedure when all I need is a simple true or

program) that returns what I want, but I'm having trouble
executing that function from PHP. I don't have a problem with a
stored procedure that returns values

or

a stored procedure that returns a result set.

Is there something special/different about functions?

Thanks!
