I'm using the jquery validator supplied here: http://bassistance.de/jquery-plugins/jquery-plugin-validation/
The form I made has six different sections corresponding to six different sets of information being entered. For clarity, I should mention that this is an RSVP form, and the user is able to RSVP for up to six people. The sections and input fields are numbered accordingly: section1 firstname1 lastname1, section2 firstname2 lastname2... section6 firstname6 lastname6 To indicate how many people are being entered, there is a radio button, and the user is required to select a number 1 through 6. (i.e. if the number "3" is selected, the user is RSVPing for 3 people, and thus must enter all required information for person 1, person 2, and person 3.) The problem is that I don't know how to require validation on a certain field if one of several conditions are met. This works: 'firstname2': { required: "#guests_two:checked", }, This does not: 'firstname2': { required: "#guests_one:checked", required: "#guests_two:checked", }, This does not: 'firstname2': { required: "#guests_one:checked" || "#guests_two:checked", }, This does not: 'firstname2': { required: "#guests_one:checked" }, 'firstname2': { required: "#guests_two:checked" }, Any help would be greatly appreciated!
