What exactly are you refering to? question about taking information off the form or question relating to the input of data into the DB/
If it is the former i cannot help as i have not learned that yet, however SQL language is Easy

INSERT INTO table_name
VALUES (value1, value2, value3,...);

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...);

both those examples were plagiarized from w3schools. Really good information on here and easy to follow this was one of the sites i studied whilst doing Modules on Databases, helped me receive a 7 or high distinction.

they also have tutorials on ASP PHP CSS HTML etc. study that,and you will work out your own answer it is very easy working on database.
If your database is already functional with tables and relations correctly assigned and constrained with DDL the rest is easy, Designing a good EER DB is a fair bit mor challenging, hence why those guys are some of the best paid in the industry

Here is a link that shows examples on PHP
will give you the general format

still though check out w3schools they have good information easily explained covering all the basics. another place to look for questions others have already answered is SQLteam.com I also regularly go through there reading threads and learning more.
