As a work-around, I was able to use a multiple-choice field with two options, both of which conditionally show a new field. Making that multiple-choice field required, technically makes either of the two conditional fields below it required.</p> <p>Not the most ideal solution, but in an either or instance, it does the trick.</p> <p>I, like many others, still vote for the ability to group fields (beyond sections), and apply conditional requirement logic to the fields in groups :) </p> https://legacy.forums.gravityhelp.com/topic/making-at-least-one-of-two-fields-mandatory#post-26312 Wed, 25 May 2011 15:31:31 +0000 Carl Hancock 26312@https://legacy.forums.gravityhelp.com/ <p>There is no built in way to make one or the other required. A field is either required, or it is not required.</p> <p>You can, however, write your own custom validation using the gform_validation hook. So you could do this as a customization.

Is there a way to apply conditional logic to make at least one of any X fields required? </p> https://legacy.forums.gravityhelp.com/topic/making-at-least-one-of-two-fields-mandatory#post-25517 Sat, 14 May 2011 01:07:02 +0000 dmjarvis 25517@https://legacy.forums.gravityhelp.com/ <p>In one of my contact forms I have a field for telephone number and a field for email address. I don't want to force my visitors to enter both fields, but I would like at least one of them entered before the form can be submitted.</p> <p>Is there a way of making 'at least one' of a group of fields mandatory?</p> <p>Thanks. </p>
