Question

Hi have some forms that I want to use some basic php validation (regular expressions) on, how do you go about doing it? I have just general text input, usernames, passwords and date to validate. I would also like to know how to check for empty input boxes. I have looked on the interenet for this stuff but I haven’t found any good tutorials.

Thanks

1. Read in the PHP.net documentation on Text processing.
2. Use the string methods and regular expressions to make a function for email type, date type etc., returning true if valid, false otherwise.
3. Test with the functions when submitting the form, and display the appropriate error messages to the user.
