Form Checking - Verifying Name Using PHP Ereg
June 23, 2006 @ 07:40:01

On WebProNews.com, there's a brief tutorial on using regular expressions, specifically for filtering "names" entered by users.

One important use of Regular Expressions (Regex) is to verify fields submitted via a form. In this article, we attempt to write an expression that is able to verify the user's first name, middle name, last name or just names in general.

The expression should allow names such as "Mary", "Mr. James Smith" and "Mrs O'Shea" for example. So the challenge here is to allow spaces, periods and single quotation marks in the name field and reject any other characters.

Their examples use the preg_* functions in PHP to work, first looking for any invalid characters in the string(s), then amending it to ensure that there aren't any numbers involved either. The few lines of code it takes are included as well.
