You just need to pass the name of a global function to the ValidationServerFunction and make it return 1 if the field is valid. For instance I use this function in conjunction with the email validation class to figure if the e-mail address is acceptable. AddInput( ... "ValidationServerFunction"=>"ValidateEmailBox" ... ); Function ValidateEmailBox($email) { global $global_options; $validator=new email_validation_class; $validator->timeout=10; $validator->localuser="info"; $validator->localhost="phpclasses.UpperDesign.com"; return($validator->ValidateEmailBox($email)!=0); } >2) How can I validate the following: A drop down ><select> box contains an item: other.

I don't have a automatic solution for that. You may use either a client side or server side function to check if the value in the select field is set and then figure if you are going to validate the other field. >3) If validation of the whole form passed, is it >somehow possible to format the layout of the output >which is sent back with the submitted and accepted >values? > >Eg.: If in the example above the other field is left >blank (the user selected a value from the drop down >menu), s/he did not need to use the 'other' field. >After validation, would it be possible that the blank >other field would not even show up?

You have the complete control over the layout. You may use a PHP conditional statement (if) and only add the fields and data to the form output that you want to show. >4) How can I validate that the sum of 3 numeric input >fields should not be more than 50? (Possibly with >server side validation, instead of JavaScript.) Again, client side or server side validation custom functions passed with "ValidationClientFunction" or "ValidationServerFunction" parameters.
