Search engine form validation.

[co.ador]

 

I have a form that has 5 fields, One is name, zip, state and two string arrays.

 

When validating the name input field what other checking beside isEmpty and isNull has to be done in the input field name in order to fully validate the field?

if you're going to use the string in a SQL query make sure you use mysql_real_escape_string().

What you should really use is isset, instead of isNull. And what is isEmpty, Do you mean empty?

 

mysql_real_escape_string is a good idea for queries to check for injection. But you've not told us much more, so it's hard to suggest much.
