/*

Codes:

"req"             - required - field should not be empty
"maxlen=x"        - checks the length entered to a maximum x 
"minlen=x"        - checks the length entered to a minimum x 
"alnum"           - field is alpha or numeric 
"alnum_s"         - field is alpha, numeric or white space 
"num"             - field is numeric 
"alpha"           - field is alpha 
"alpha_s"         - field is alpha with white space 
"email"           - validates email address 
"lt=x"            - value is less than x (only for numeric fields) 
"gt=x"            - value is greater than x (only for numeric fields) 
"regexp=x"        - enter any regular expression for x, and it will validate 
"dontselect=x"    - set x = 0 if you have a select box with the first option of "-Choose One-" or a value you don't want them to select 
"dontselectchk=x" - the user should not select this checkbox; here x is the value tied to the checkbox 
"shouldselchk=x"  - the user should select the checkbox; here x is the value tied to the checkbox 
"selone_radio"    - checks to make sure at least one radio button is checked
