Regular expression to alphanumeric plus some special characters

Hi there,

I need to validate an input field.  The input allowed should be 'alpha numeric, spaces, and some special characters.  As this data is feeded into a database as a name, I want to know if there are any characters that I should avoid.  Can you please let me know the regular expression to filter this input.  Thanks.

You can put any characters in the database if you use a prepared statement and your apps handle cross site scripting. If not, then you might want to exclude characters depending on the app which uses the data.

You can test the above regex and modify/test it here: http://regexr.com/3bn8q
